Description

CROSS-REFERENCE OF RELEVANT APPLICATION



[0001] The present application claims priority of a Chinese patent application for a utility model with application No. 201721476126.1 filed on November 7, 2017

FIELD



[0002] Embodiments relate to a power distribution apparatus, and more specifically, to a low-voltage power distribution apparatus in an application aspect.

BACKGROUND



[0003] At present, various low-voltage power distribution apparatuses (also known as low-voltage power distribution accessory products), such as leakage protectors, arc fault protectors and overvoltage/undervoltage protectors etc., are connected between the main power supply and the load circuit to protect the main power supply or the load circuit from leakage, arc and overvoltage/undervoltage and further guarantee safe use of the main power supply or the load circuit. Some low-voltage power distribution apparatuses can provide one or more of the above functions. Conventional low-voltage power distribution apparatus has a closed state and an open state. In the closed state, the low-voltage power distribution apparatus connects the main power supply to the load circuit; in the open state, the low-voltage power distribution apparatus disconnects the main power supply from the load circuit. The low-voltage power distribution apparatus generally is provided with a control circuit board which can control a tripping mechanism to trip in case of faults like leakage, arc and overvoltage/undervoltage, such that the low-voltage power distribution apparatus is switched from the open state to the closed state, thereby preventing the above faults from damaging the power supply or the load.

[0004] The low-voltage power distribution apparatus usually adopts a connection approach of an upper incoming line, i.e., an incoming line connecting the main power supply is connected from an upper interface of the low-voltage power distribution apparatus while a lower interface of the low-voltage power distribution apparatus is connected to the load circuit. Most of the low-voltage power distribution apparatuses are also designed for the upper incoming line. Accordingly, in case of the above fault in the circuit or the low-voltage power distribution apparatus, the low-voltage power distribution apparatus cutting off the power supply of the control circuit board while triggering the tripping. A variety of low-voltage power distribution apparatuses employing the connection approach of the lower incoming line are also developed to satisfy various needs of the uses, for example, the users are forced to connect the main power supply to the load circuit via the lower incoming line due to different reasons. The lower incoming line, just as the name implies, means that the main power supply is connected to the lower interface of the low-voltage power distribution apparatus, and the load circuit is connected to the upper interface. However, because the interior circuits of the low-voltage power distribution apparatus are not adjusted correspondingly, different problems occur when the low-voltage power distribution apparatus adopts the connection approach of the lower incoming line.

DETAILED DESCRIPTION OF EMBODIMENTS



[0016] Principles of the present disclosure will now be described with reference to various example embodiments illustrated in the drawings. It should be appreciated that description of those embodiments is merely to enable those skilled in the art to better understand and further implement example embodiments disclosed herein and is not intended for limiting the scope disclosed herein in any manner. It should be noted that similar or same reference signs can be used in the drawings under feasible cases, and similar or same reference signs can represent similar or same functions. Those skilled in the art can easily recognize that alternative embodiments of the structure and method described in the text can be employed from the following description without deviating from the principles of the present disclosure depicted in the text.

[0017] As used herein, the term "includes" and its variants are to be read as open-ended terms that mean "includes, but is not limited to." The term "based on" is to be read as "based at least in part on." The term "one embodiment" is to be read as "at least one embodiment." The term "a further embodiment" is to be read as "at least one further embodiment."

[0018] A low-voltage power distribution apparatus is generally provided with a control circuit board, on which a detecting module is provided for detecting faults, such as leakage, arc and undervoltage/overvoltage etc., and sending detection results in the form of electrical signals to a control unit. The control unit will determine, according to the signals, presence of a tripping condition that causes the low-voltage distribution apparatus to trip in the circuit, so as to send a tripping trigger signal that triggers a tripping mechanism to trip. The tripping mechanism performs a tripping action based on the tripping trigger signal. In certain low-voltage power distribution apparatuses, it is also possible that the detecting module is not disposed on the control circuit board and instead powered by an individual power supply.

[0019] Under certain situations of the low-voltage power distribution apparatus, especially when its connection is performed with a lower incoming line, the low-voltage power distribution apparatus continues to use the control circuit board employed when using an upper incoming line, which causes many problems. For example, the lower incoming line refers to connecting a main power supply to a lower interface of the low-voltage power distribution apparatus; in such case, although the control circuit board, upon detecting the above faults, can control the tripping mechanism to perfrom the tripping action to disconnect the main power supply from a load circuit, the control circuit board is still charged as the main power supply is connected from the lower interface after the tripping (i.e., in the open state of the low-voltage power distribution apparatus).

[0020] The control circuit board can achieve various functions as long as it is charged. That is, the control units still can send, according to the tripping condition, the tripping trigger signals to the tripping mechanism which performs a tripping action based on the signals. In this event, however, the low-voltage power distribution apparatus in the open state will not respond to the tripping action. In other words, the tripping mechanism will always perform useless operations in this case, which usually leads to burnout of the tripping mechanism and further damages the entire low-voltage power distribution apparatus.

[0021] In view of the above problem, some low-voltage power distribution apparatuses with the lower incoming line disable the fault detecting mechanism after the tripping, to avoid the burnout of the tripping mechanism. In such case, if the faults in the circuit still exist, users also can perfrom a closing operation. As the fault detecting mechanism is disabled at this moment, the control unit will not receive fault signals from the fault detecting mechanism and accordingly will not send a tripping trigger signal. The tripping mechanism therefore will not perform actions. That is, in case of circuit faults, the circuit is still connected and the low-voltage power distribution apparatus warns the users of the faults just by a flickering alarm light. Although the damage to the tripping mechanism and even to the low-voltage power distribution apparatus is avoided in the above scenario, it may bring more serious problems. For example, users may fail to notice the flickering alarm light and continue to perform other work, which may damage the load in the circuit and further threaten users' safety.

[0022] Embodiments of the present disclosure provide a low-voltage power distribution apparatus 200 capable of detecting a predetermined state to address or at least partially address the above and other potential problems of the traditional solutions.

[0023] Improvements of the low-voltage power distribution apparatus 200 in accordance with example embodiments of the present disclosure are described in details below with reference to FIGS. 1 to 5. FIG. 1 illustrates a structural diagram of the detecting unit and the test assembly of the low-voltage switching device in accordance with example embodiments of the present disclosure. The improved low-voltage power distribution apparatus 200 is introduced below with reference to FIG. 1.

[0024] In general, according to FIGS. 1 to 3, the low-voltage power distribution apparatus 200 according to embodiments of the present disclosure includes a group of conductive pins, an elastic element 205 and a drive part 209. The group of conductive pins at least includes two conductive pins (hereinafter referred to as first conductive pin 203 and second conductive pin 204 for the sake of description). The elastic element 205 includes an helix portion 206 and at least one free end protruding from the helix portion, namely, a first free end 207. The helix portion 206 is conductively sleeved on the first conductive pin 203. The drive part 209 is pivotablly arranged inside the low-voltage power distribution apparatus 200 and rotatable from a first position P1 to a second position P2 when the low-voltage power distribution apparatus 200 is being switched to a predetermined state. The drive part 209 at the second position P2 can force the first free end 207 of the elastic element 205 to contact the second conducive pin 204.

[0025] According to the above structure, after the low-voltage power distribution apparatus 200 is switched to the predetermined state, a conductive path from the second conductive path 204, via the first free end 207 of the elastic element 205, to the first conductive pin 203 is formed by the contact of the first free end 207 with the second conductive pin 204. Accordingly, the low-voltage power distribution apparatus 200 according to embodiments of the present disclosure can transmit, via the conductive path, the predetermined state of the low-voltage power distribution apparatus 200 to the control unit 202 of the low-voltage power distribution apparatus 200. The above setting allows the control unit 202 to control the tripping mechanism based on the predetermined state of the low-voltage power distribution apparatus, which is equivalent to a closed-loop control for detecting the predetermined state. In this way, the low-voltage power distribution apparatus can be controlled more intelligently.

[0026] In some embodiments, the predetermined state may include a closed state. In other words, the tripping action is triggered only when the low-voltage power distribution apparatus is detected in the closed state and also satisfies the tripping condition.

[0027] It is to be understood that the predetermined state may also include other states, such as an open state, or a state of upper incoming line, or a state of lower incoming line. In some embodiments, the control unit may correspondingly perform the control based on the state of upper incoming line state or lower incoming line and the closed state or the open state. The low-voltage power distribution apparatus is described in details below with the closed state as an example predetermined state. It should be understood that the following description is also suitable for the low-voltage power distribution apparatus with the predetermined state comprising other states.

[0028] In some embodiments, after the control unit 202 of the low-voltage power distribution apparatus 200 according to embodiments of the present disclosure receives a closed state signal, the control unit 202 controls the low-voltage power distribution apparatus 200 to trip if the tripping condition still exits in the circuit. That is, even if the tripping condition still exists in the open state, the control unit 202 will not trigger any actions due to failure of detecting or receiving predetermined state signals and the tripping mechanism accordingly will not perform any actions. Therefore, a detecting unit 100 arranged for detecting the closed state achieves a closed-loop control of the low-voltage power distribution apparatus 200. The control unit 202 can make a clearer judgment of the state of the low-voltage power distribution apparatus 200, so as to avoid damaging the low-voltage power distribution apparatus 200 and its load and circuit.

[0029] The first free end 207 connects a power supply 215 to the detecting unit 100 only in the closed state, to allow the detecting unit 100 to send a closed state signal to the control unit 202. However, after the low-voltage power distribution apparatus 200 is tripped, the detecting unit 100 is disconnected from the power supply 215. At this time, the detecting unit 100 is not powered and thus cannot send the closed state signal. The closed state is detected simply by the detecting unit 100 and a connection assembly 201, and the above detecting function can be fulfilled almost without any structural adjustments to the conventional low-voltage power distribution apparatus, which saves costs and also enhances reliability of the low-voltage power distribution apparatus. In this way, even if the tripping condition exists in certain low-voltage power distribution apparatuses, the tripping action will not be constantly triggered under the open state, especially those adopting the lower incoming line, thereby prolonging the service life of the low-voltage power distribution apparatus 200.

[0030] In some embodiments, the control unit 202 may be directly coupled to the first conductive pin 203 or indirectly coupled thereto via a filter circuit, a modulation circuit or a detecting unit. In some embodiments, the second conductive pin 204 may be coupled to the power supply 215, so as to inform the control unit 202 of the closed state by connecting the power supply 215 to the control unit 202 when the first conductive pin 203 and the second conductive pin 204 are connected. In some embodiments, the power supply 215 may be a step-down module in the low-voltage power distribution apparatus 200. The step-down module lowers the voltage of the main power supply to provide electricity power for the detecting unit 100. In some embodiments, the power supply 215 may be an individual battery etc.

[0031] In some embodiments, the low-voltage power distribution apparatus 200 may also include the detecting unit 100, through which the first conductive pin 203 may be indirectly coupled to the control unit 202. In some embodiments, the detecting unit 100 may be a circuit as shown in FIG. 1. The circuit, when connected to the power supply 215, can send electric signals at an output and the control unit 202 can determine that the low-voltage power distribution apparatus 200 is in the closed state after receipt of the electric signals. It is to be understood that the detecting unit 100 may also take other forms as long as it can send the closed state signals when connected to the power supply 215.

[0032] In some embodiments, the low-voltage power distribution apparatus may also include a tripping mechanism (not shown). The control unit 202 sends the tripping trigger signal to the tripping mechanism to perfrom the tripping action. In some embodiments, the detecting unit 100, the power supply 215, the connection assembly 201, the control unit 202 and the tripping mechanism may be disposed on the control circuit board (not shown) in the low-voltage power distribution apparatus. The control circuit board may be an integral circuit board or of a separated structure. Each module is respectively located in different separated structures to more accurately control each unit or module.

[0033] How the circuit is connected by allowing a second contact portion 207 to contact the second conductive pin 204 under the closed state situation in some embodiments with reference to FIGS. 2 and 3 will be described as below. FIG. 2 illustrates a side view of the low-voltage switching device in the closed state in accordance with example embodiments of the present disclosure; FIG. 3 illustrates a side view of the low-voltage switching device in the open state in accordance with example embodiments of the present disclosure. As shown, the low-voltage power distribution apparatus 200 may also include a handle 208 in some embodiments. The handle 208 is at least partially disposed external to the low-voltage power distribution apparatus 200 for operations by users. In response to users' operations, the handle 208 can be switched between two positions (respectively known as a closed position and an open position for the sake of description). When the handle 208 is at the closed position, the low-voltage power distribution apparatus 200 is in the closed state; when the handle 208 is at the open position, the low-voltage power distribution apparatus 200 is in the open state.

[0034] During the switching of the handle from the open position in FIG. 3 to the closed position in FIG. 2, the drive part 209 can be driven to rotate from the first position P1 to the second position P2. During the above process, the drive part 209 forces the second contact portion 207 to contact the second conductive pin 204, such that the second contact part 207 contacts the second conductive pin 204 in the closed state to achieve the connection between the detecting unit 100 and the power supply 215.

[0035] As described above, the low-voltage power distribution apparatus 200 is switched from the closed state to the open state via the tripping action, to disconnect the main power supply from the load circuit. It is to be understood that the low-voltage power distribution apparatus 200 may also be switched from the closed state to the open state via the handle 208. No matter the low-voltage power distribution apparatus 200 is switched from the closed state to the open state via the tripping action or the handle 208, the handle 208 is correspondingly switched from the closed position to the open position. The drive part 209 therefore rotates back to the first position P1 from the second position P2. At this time, the second contact portion 207 is no longer forced by the drive part 209 and is further disconnected from the contact with the second conductive pin 204, thereby disconnecting the connection between the detecting unit 100 and the power supply 215.

[0036] In some embodiments, the elastic element 205 is a torsion spring as shown in FIGS. 1, 2 and 3. It is to be understood that the elastic element 205 may also take other forms as long as it can implement the above functions. In some embodiments, the elastic element 205 may also include a second free end 213 and the low-voltage power distribution apparatus 200 further includes a test assembly 210, which for example may test validity of the low-voltage power distribution apparatus 200. In some embodiments, the test assembly 210 includes a test unit 211, a test pin 212 and a test button 214. In some embodiments, the test unit 211 may be a circuit connected to a corresponding module to be tested. The test unit 211 is coupled to the test pin 212 and in response to a press of the users, the test button 214 can drive the second free end 213 to contact the test pin 212, such that the power supply 215 is connected to the test unit 211 to power the test unit 211 in the closed state (i.e., when the first free end 207 contacts the second conductive pin 204).

[0037] As shown in FIG. 1, the test unit 211 may be a circuit implementing the test functions. It is to be understood that the test unit 211 may also take other forms as long as it can fulfill the test functions.

[0038] According to FIGS. 4 and 5, it can be seen from the above that the first conductive pin 203, the second conductive pin 204 and the test pin 212 are arranged parallel to each other in the low-voltage power distribution apparatus 200. With the form of a pin, the conductive pin can act as a fulcrum or a pivot of the movement of certain components, such as elastic element while enabling the conductive function. The three conductive pins, i.e., first conductive pin 203, second conductive pin 204 and test pin 212, may be made of metallic materials.

[0039] It is to be understood that instead of the form of a pin, the first conductive pin 203, the second conductive pin 204 and the test pin 212, for example, may be any other forms of contact structures which are arranged individually in the low-voltage power distribution apparatus 200 and can implement circuit conduction.

[0040] In some embodiments, considering the structural requirements in the low-voltage power distribution apparatus 200, the first free end and the second free end may have a suitable length and may be bent or deformed to allow the elastic element to adapt to the setting of the first conductive pin 203, the second conductive pin 204 and the test pin 212 in the low-voltage power distribution apparatus 200. For example, in the embodiments shown by FIGS. 2 to 5, the second conductive pin 204 and the test pin 212 may be respectively disposed at two different sides of the first conductive pin 203 (respectively known as first side and second side for the sake of description). For example, the second conductive pin 204 may be arranged on the first side of the first conductive pin 203 while the test pin 212 may be disposed on the second side of the first conductive pin 203 opposite to the first side. Such arrangement can more reasonably utilize the limited space within the low-voltage power distribution apparatus 200 to obtain a more rational spatial layout.

[0041] In some embodiments, the low-voltage power distribution apparatus 200 may further include a bending pin 216 as shown in FIGS. 2 and 3 The bending pin 216 is arranged on the same side of the first conductive pin 203 as the test pin 212, i.e., the second side. The first free end 207, after being bent by the bending pin 216, is adjacent to the second conductive pin 204 in the open state or contacts the second conductive pin 204 in the closed state. In other words, by providing the bending pin 216, the first free end 207, which is originally pivoted at the first conductive pin 203, is extended to pivot at the bending pin 216. The above arrangements reduce the driving force of the drive part 209 for driving the first free end 207 to contact the second conductive pin 204 and meanwhile rationalize the spatial layout.

[0042] In some embodiments, the low-voltage power distribution apparatus 200 also includes an alarming mechanism (not shown), which can send an alarm to the users when the fault detecting mechanism detects the tripping condition in the circuit. For example, the alarming mechanism may send a light alarm, a sound alarm or a combination thereof according to the tripping condition to warn the users of the faults in need of immediate maintenance in the circuit.

Those skilled in the art should understand that the above embodiments can be modified without deviating from the scope and spirits of the present disclosure.
