GAS INSULATED SWITCHING DEVICE AND CAMERA SYSTEM FOR OPTICAL CHECK OF SWITCHING POSITION IN THE SWITCHING DEVICE

Description

[0001] The invention relates to a gas insulated switching device with a gastight housing, wherein switching means are mounted in the housing, provided with an optical window on which an external camera can be positioned outside the housing on a support element in such, that the contacts and/or the contact positions of a switch or of switches can be displayed by this camera on a display screen, and with a switchable light source, which illuminates the aforesaid area the camera is focused on to display the contact positions of a switch or switches.

[0002] A switchgear with a camera system adapted to the switchgear housing, in order to make the position of the internal of the switches visable, is shown in CA 2 274 854 A1. CA 2 274 854 A1 relates to switch panels - either monopolar or multipolar, with metal enclosure, divided into compartments or gas insulated of a switch facility, connected by means of three-switch disconnectors operating both as a circuit breaker and a ground connection, to power switches provided or not with vacuum switches and mounted, as need be, in busbar cabinets or in separate circuit-breaking cabinets, and fitted with transmitting devices for the visual recording of fixed contacts. The transmitting equipment includes a camera module which can be linked through a connection mechanism to a display unit outside the switch panel, while a lighting device mounted out of alignment relative to the camera module is provided to enable a glare-free display of the fixed busbar contacts.

[0003] In CA 2 274 854 A1, the camera is fixed directly to the housing of switchgear, in order to be a fixed installed part of the switchgear.

[0004] DE9312384U1 relates to attachment of an endoscope to the window of a switchgear.

[0005] The resulting disadvantage is, that for each switchgear panel a separate camera is need.

[0006] So it is the object of the invention, to use a camera system in a easier and cost effective way, considering, that direct optical control of specific switch positions are not desired oftenly.

[0007] In an aspect, there is provided a gas insulated switching device with a gastight housing as defined in appended claim 1.

[0008] Based on that, the invention is, that the camera is a portable camera which is positionable only temporarily, and the support element as well as the camera itself are provided with complementary means for the temporarily positioning of the portable camera to the support.

[0009] "Temporarily" means for the time, when the observation of the contact position is required.

[0010] So important for the invention is, that the camera is not a part of the switchgear, but separated from that. So with that, in difference to the mentioned state of the art, one single camera can be used for several switch gears, because it is portable.

[0011] According to the invention the support element and the camera are provided with complementary magnetic elements, in such, that the portable camera can be attached to the support temporarily in the aforesaid optically centered, precalibrated optical and mechanical position, in order to make the contacts and/or the contact positions of the switch or of the switches visible on a display screen.

[0012] "Optically centered" includes also the meaning focused to the elements which are important to observe, like the contact pieces, or indicating elements of the contact pieces fixed to the contact piece, by which the contact position can be observed.

[0013] According to the invention the complementary support elements on the support of the switching device housing are magnetic rings or elements, with interacting mechanical guiding pins and holes for a temporarily and centered predetermined reproducable positioning of the portable camera in the aforesaid position.

[0014] The support element is provided as an adapter element, with magnetic elements near its periphery, and with a centering ring for the camera lens adaption.

[0015] To the invention concerns directely a Camera system for temporarily adaption to a gasinsulated switching device or a switchgear panel.

[0016] The camera is a portable camera which can be temporarily attached to a support element of a switchgear housing of the panel.

[0017] The camera system also includes or is connectable to a portable display.

[0018] So the portable observation system consist of camera, display, light source, power supply, cables and an transport box for this equipment.

[0019] The portable camera system is transported in a carrying case, and that the display is mounted directly in the carrying case.

[0020] By this, only one camera system is need for several switchgear panels.

[0021] The invention is shown in the figures.

Figure 1: Camera system in use at a medium voltage switchgear housing

Figure 2. Adapter

[0022] Figure 1 shows a housing of a gas insulated medium voltage switchgear 1, with defined windows in the housing, where the light source 4 as well as the camera 2 can be attached temporarily, that means when needed for a sure observation of the switching contacts position of the disconnector or earthing switch inside the switchgear housing. Therefore an attachable adapter 7, like also shown in figure 2, for the light source 4 as well as a further attachable adapter for the camera 2 can be fixed temporarily by magnetic means. The contures of each adapter and each window are provided complementary, so that the camera and the light source can be attached in a selfadjusting way, in order to be focused to the contact positions which have to displayed. Both, camera 2 and light source 4 are attachable externally to the housing 1. Camera 2 and light source 4 are not a fixed part of the switchgear housing of the panel, but interchangeable and therefore portable.

[0023] So the camera 2 and the light source 4 can be attached to the windows of the switchgear housing 1. Light source 4 and camera 2 are electrically connected with a power source 3 which is implemented for example in the portable case 10, where also the display 6 is located. Camera and light source are activated by the electronic means inside the case 10.

[0024] The display 6 is integrated into the upper part oft the openable case 10.

[0025] The case 10 is inside in such a way portioned, that also the portable camera 2 and the portable light 4 can be transported after the use

[0026] So the compelte system includes also the aforesaid case 10, in order to have fully transportable system.

[0027] Figure 2 shows the adapter 7. This adapter 7 is provided with magnet elements near the periphery, in order to attach this adapter as a support for the light source, in this case for example LED-elements 9 intergated into the inner opening of the adapter 7.

[0028] For the camera 2, the adapter 7 is the same, except of the integrated light source.

[0029] This adapter is the aforesaid support for the camera.

[0030] As fixation means are here used magnetic elements 8.
