CROSS-REFERENCE TO RELATED APPLICATIONS
TECHNICAL FIELD
[0002] The present invention relates to a mechanical interlock mechanism, in particular
a mechanical interlock mechanism for electrical devices.
BACKGROUND ART
[0003] As is known, the function of an isolating switch is to disconnect a circuit having
no load current, so that there is a clear disconnection point between equipment being
overhauled and a power supply, to ensure the safety of maintenance personnel. A fast
ground switch is a special-purpose ground switch which has a certain short circuit
current closing capacity; the function thereof is to put the equipment being overhauled
into a grounded state, i.e. the equipment being overhauled is switched to a maintenance
state.
[0004] In view of electrical safety considerations, an isolating switch can only be operated
once a circuit breaker has opened, and a fast ground switch can only perform a closing
operation once the isolating switch is in an open state. Moreover, since the fast
ground switch is connected to the isolating switch on one side, if the isolating switch
is closed when the fast ground switch is still closed, i.e. the elements (circuit,
power supply etc.) on the other side of the isolating switch are connected to ground,
a major short circuit accident will occur, so the isolating switch can only be closed
once the fast ground switch has been opened.
[0005] However, since the fast ground switch needs to perform fast closing and opening during
operation, whereas the closing and opening operations of the isolating switch are
slow, those skilled in the art have developed a novel mechanical interlock mechanism
for electrical devices in order to ensure electrical safety and also to ensure coordination
and continuity during interlocking operations, such that only one of the fast ground
switch and the isolating switch is in a closed state while the other is in an open
state.
[0006] Document D1 (
FR 1 587 240 A) discloses a mechanical interlock mechanism for electrical devices, comprising a
first rotary element 5 with a first track, a second rotary element 8 with a second
track, a first linkage element 4, wherein one end being capable of moving along the
first track, and a second linkage element 11, wherein one end being capable of moving
along the second track.
CONTENT OF THE INVENTION
[0007] The object of the present invention is to provide a mechanical interlock mechanism
for electrical devices, which is capable of controlling two electrical devices connected
thereto to realize connection or disconnection asynchronously, ensuring the reliability
of the interlock operation thereof while reducing the action delay.
[0008] The object is met by the independent claim. Further preferred embodiments are part
of the dependent claims.

PARTICULAR EMBODIMENTS
[0011] To furnish a clearer understanding of the technical features, object and effects
of the present invention, particular embodiments of the present invention are now
explained with reference to the accompanying drawings, in which identical labels indicate
identical parts. In the drawings representing various embodiments, numbers with the
same last two digits represent components with the same structure, or with similar
structures but the same function.
[0012] To make the drawings appear uncluttered, only those parts relevant to the present
invention are shown schematically in the drawings; they do not represent the actual
structure thereof as a product. Furthermore, to make the drawings appear uncluttered
for ease of understanding, in the case of components having the same structure or
function in certain drawings, only one of these is drawn schematically, or only one
is marked.
[0013] Figs. 1 and 2 shows a mechanical interlock mechanism according to an embodiment of
the present invention, for controlling two different electrical devices in a cooperative
manner. Specifically, the mechanical interlock mechanism comprises: a first rotary
element 11 and a second rotary element 12. The first rotary element 11 and second
rotary element 12 can rotate synchronously about the same shaft 30. It is worth pointing
out that a first track 111 is also provided on the first rotary element 11, while
a second track 121 is also provided on the second rotary element 12.
[0014] Moreover, the mechanical interlock mechanism also comprises a first linkage element
21 and a second linkage element 22, the first linkage element 21 and the second linkage
element 22 each having two ends. One of the ends of the first linkage element 21 can
move along the first track 111 on the first rotary element 11; one of the ends of
the second linkage element 22 can move along the second track 121 on the second rotary
element 12.
[0015] It is worth pointing out that during synchronous rotation of the first rotary element
11 and second rotary element 12, the first linkage element 21 passes a first section
111a of the first track 111, the second linkage element 22 passes a first section
121a of the second track 121, and the first linkage element 21 and the second linkage
element 22 are in different states. Specifically, when the first linkage element 21
is in a moving state, the second linkage element 22 is in a stationary state; when
the first linkage element 21 is in a stationary state, the second linkage element
22 is in a moving state.
[0016] The first linkage element 21 and second linkage element 22 of the mechanical interlock
mechanism are connected to two different electrical devices, for instance a fast ground
switch and an isolating switch, respectively in a cooperative manner, so as to be
capable of realizing an arrangement whereby when one of the electrical devices is
in a connected state, the other electrical device is in a disconnected state, and
when one of the electrical devices is in a disconnected state, the other electrical
device is in a connected state. Since only one of the electrical devices can be connected
each time, while the other is in a disconnected state, it is possible to realize interlock
effectively, and realize anticipated disconnection and connection of a circuit through
predetermined operations of the first linkage element 21 and second linkage element
22, to ensure electrical safety.
[0017] Preferably, the first track 111 or the second track 121 consists of multiple sections
of arc. Referring to Fig. 2, the first track 111 and second track 121 are both of
irregular arcuate shape; the first linkage element 21 and second linkage element 22
perform non-continuous movement in the first track 111 and second track 121 respectively,
so as to control electrical devices connected thereto to realize connection or disconnection
asynchronously.
[0018] According to a preferred embodiment of the present invention, the first track 111
also comprises a second section 111b connected at one end of the first section 111a
of the first track 111. The first section 111a and second section 111b of the first
track 111 are separated from the shaft 30 by different distances. Specifically, the
distance between the first section 111a of the first track 111 and the shaft 30 is
variable, the distance between the second section 111b of the first track 111 and
the shaft 30 is constant, and the distance between the second section 111b of the
first track 111 and the shaft 30 is greater than the distance between the first section
111a of the first track 111 and the shaft.
[0019] According to a specific embodiment, the first section 111a of the first track 111
is of an irregular arcuate shape, and is separated from the shaft 30 by a gradually
increasing distance. The second section 111b of the first track 111 is of a regular
arcuate shape, and is separated from the shaft 30 by a constant distance. The first
linkage element 21 is in a moving state in the first section 111a, and in a stationary
state in the second section 111b.
[0020] The second track 121 also comprises a second section 121b connected at one end of
the first section 121a of the second track 121. The first section 121a and second
section 121b of the second track 121 are separated from the shaft 30 by different
distances. Specifically, the distance between the first section 121a of the second
track 121 and the shaft 30 is constant, the distance between the second section 121b
of the second track 121 and the shaft 30 is variable, and the distance between the
second section 121b of the second track 121 and the shaft 30 is greater than the distance
between the first section 121a of the second track 121 and the shaft 30.
[0021] According to a particular embodiment, the first section 121a of the second track
121 is of a regular arcuate shape, and is separated from the shaft 30 by a constant
distance. The second section 121b is of an irregular arcuate shape, and is separated
from the shaft 30 by a gradually increasing distance. The second linkage element 22
is in a stationary state in the first section 121a, and in a moving state in the second
section 121b.
[0022] It is worth pointing out that in order to ensure continuity of movement between the
first linkage element 21 and second linkage element 22, and reduce action delay, the
central angle corresponding to the first section 111a of the first track 111 is the
same as the central angle corresponding to the first section 121a of the second track
121. The central angle corresponding to the second section 111b of the first track
111 is the same as the central angle corresponding to the second section 121b of the
second track 121.
[0023] As the first rotary element 11 rotates, the first linkage element 21 will switch
from a moving state to a stationary state at a particular moment; at this time, the
first linkage element 21 will not stop moving immediately, but continue to move forward
a certain distance due to its own inertia. In order to prevent the first rotary element
11 from experiencing certain shock and bumping, it is preferred that a safe movement
buffer distance must also be reserved for the first linkage element 21 on the first
track 111 of the first rotary element 11.
[0024] Specifically, according to a preferred embodiment of the mechanical interlock mechanism
of the present invention, the first track 111 also comprises a third section 111c,
located at the other end of the first section 111a of the first track 111. The distance
between the third section 111c of the first track 111 and the shaft 30 is constant,
and less than the distance between the second section 111b of the first track 111
and the shaft 30.
[0025] By the same principle, as the second rotary element 12 rotates, the second linkage
element 22 will switch from a moving state to a stationary state at a particular moment;
at this time, the second linkage element 22 will not stop moving immediately either,
but continue to move forward a certain distance due to its own inertia. In order to
prevent the second rotary element 12 from experiencing certain shock and bumping,
it is preferred that a safe movement buffer distance must also be reserved for the
second linkage element 22 on the second track 121 of the second rotary element 12.
[0026] Specifically, according to a preferred embodiment of the mechanical interlock mechanism
of the present invention, the second track 121 also comprises a third section 121c,
located at another end of the second section 121b of the second track 121. The distance
between the third section 121c of the second track 121 and the shaft 30 is constant,
and greater than the distance between the second section 121b of the second track
121 and the shaft 30.
[0027] To realize the function of guiding the movement of the first linkage element 21,
and thereby better control an electrical device connected thereto so as to realize
anticipated on/off switching, the mechanical interlock mechanism of the present invention
also comprises a first limiting element, capable of defining the movement direction
of the first linkage element 21. According to a specific embodiment of the present
invention, the mechanical interlock mechanism also comprises a first housing 31, the
first limiting element is a third track 311 disposed on the first housing 31, the
first housing 31 is located on one side of the first rotary element 11, and another
end of the first linkage element 21 can move along the third track 311. Optionally,
the third track 311 is of a linear shape extending in a radial direction of the first
housing 31.
[0028] It is worth pointing out that in order to achieve better limiting and guiding results
while ensuring the mechanical strength of the mechanism, the mechanical interlock
mechanism preferably also comprises a third housing 33; the third housing 33 is located
on another side of the first rotary element 11, and an identical third track 311 is
also disposed thereon, as with the first housing 31. The third track 311 on the third
housing 33 and the third track 311 on the first housing 31 are parallel to each other,
and the first housing 31 and third housing 33 are both in a stationary state. In this
embodiment, two ends of the first linkage element 21 are limited in the third track
311 located on the first housing 31 and in the third track 311 located on the third
housing 33 respectively; a middle part of the first linkage element 21 is located
in the first track 111 on the first rotary element 11. Through the joint action of
the first track 111 and the third tracks 311, the first linkage element 21 is enabled
to move according to a predetermined path. It should be understood that in an optional
embodiment, the limiting element here may also be a locating sleeve, which can cooperate
with and limit the movement direction of the first linkage element 21.
[0029] To realize the function of guiding the movement of the second linkage element 22,
and thereby better control another electrical device connected thereto so as to realize
anticipated on/off switching, the mechanical interlock mechanism of the present invention
also comprises a second limiting element, capable of defining the movement direction
of the second linkage element 22. According to a specific embodiment, the mechanical
interlock mechanism also comprises a second housing 32, the second limiting element
is a fourth track 321 disposed on the second housing 32, the second housing 32 is
located on one side of the second rotary element 12, and another end of the second
linkage element 22 can move along the fourth track 321. Optionally, the fourth track
321 is of an arcuate shape extending in a radial direction of the second housing 32.
[0030] It is worth pointing out that in order to achieve better limiting and guiding results
while ensuring the mechanical strength of the mechanism, the mechanical interlock
mechanism preferably also comprises a fourth housing 34; the fourth housing 34 is
located on another side of the second rotary element, and an identical fourth track
321 is also disposed thereon, as with the second housing 32. The fourth track 321
on the second housing 32 and the fourth track 321 on the fourth housing 34 are parallel
to each other, and the second housing 32 and fourth housing 34 are both in a stationary
state. In this embodiment, two ends of the second linkage element 22 are limited in
the fourth track 321 located on the second housing 32 and in the fourth track 321
located on the fourth housing 34 respectively; a middle part of the second linkage
element 22 is located in the second track 121 located on the second rotary element
12. Through the joint action of the second track 121 and the fourth tracks 321, the
second linkage element 22 is enabled to move according to a predetermined path.
[0031] Optionally, as Fig. 1 shows, the first housing 31 and second housing 32 are disposed
on an outer side of the first rotary element 11 and the second rotary element 12 respectively.
The third housing 33 and fourth housing 34 are disposed on an inner side of the first
rotary element 11 and the second rotary element 12 respectively. To serve the function
of protecting the internal structure, the mechanical interlock mechanism for electrical
devices of the present invention also comprises: a casing 50. The first housing 31,
second housing 32, third housing 33 and fourth housing 34 are connected in a fixed
manner to the casing 50 by multiple fasteners 51 therebetween.
[0032] Preferably, the shaft 30 is a drive shaft for supplying a driving force; the first
rotary element 11 and second rotary element 12 are fitted round the drive shaft coaxially.
In order to supply a stable driving force to the mechanical interlock mechanism, referring
to Fig. 1, the mechanical interlock mechanism of the present invention also comprises:
a driving force apparatus 40, with an output end of the driving force apparatus being
connected to the drive shaft. Optionally, the driving force apparatus 40 is an electric
motor. It should be appreciated that a person skilled in the art could also use a
hydraulic or pneumatic driving apparatus according to actual circumstances; no restrictions
are imposed here.
[0033] According to an optional embodiment of the present invention, the first housing 31,
second housing 32, third housing 33 and fourth housing 34 as well as the first rotary
element 11 and second rotary element 12 can have the disk-shaped structures shown
in the figures. The first linkage element 21 and second linkage element 22 may each
have a connecting shaft structure. It should be appreciated that the shapes and structures
of these components are not unique; a person skilled in the art could make any alterations
or changes according to actual requirements, as long as the abovementioned effects
of the present invention can be achieved.
[0034] According to a particular embodiment of the present invention, as Fig. 3 shows, one
of the electrical devices, for instance a fast ground switch 60, is connected to the
first linkage element 21 via a connecting rod 61. As the first linkage element 21
moves or is stationary, it drives the connecting rod 61 synchronously, so as to control
the connection or disconnection of the fast ground switch 60. The other electrical
device, for instance an isolating switch (not shown in the drawing) is connected to
the second linkage element 22 via a crank 71. As the second linkage element 22 moves
or is stationary, it drives the crank 71 synchronously, so as to control the connection
or disconnection of the isolating switch.
[0035] In summary, during synchronous rotation of the first rotary element 11 and second
rotary element 12, when the first linkage element 21 is in a moving state, the second
linkage element 22 is in a stationary state; when the first linkage element 21 is
in a stationary state, the second linkage element 22 is in a moving state. Due to
mutual constraint of movement between the first linkage element 11 and the second
linkage element 12, the isolating switch is in a connected state when the fast ground
switch is in a disconnected state; the fast ground switch is in a connected state
when the isolating switch is in a disconnected state. Thus it is possible to reliably
and efficiently realize asynchronous on/off switching operations between two electrical
devices in a coordinated manner, to prevent the occurrence of erroneous operations.
[0036] The mechanical interlock mechanism for electrical devices according to the present
invention can ensure that only one of two electrical devices is in a connected state,
while the other electrical device is in a disconnected state. In contrast to the prior
art, the present invention can control the switching of two electrical devices connected
thereto between different states by means of just one mechanical interlock mechanism.
This not only lowers the cost thereof, but can also increase the reliability of the
interlock operation, and can reduce the action delay; at the same time, accidents
caused by operational mistakes can be avoided effectively, ensuring the safety of
operation of electrical devices.
