The high-voltage switch is an important means of high-voltage switch automatic control equipment for power system power generation, transmission, distribution, control and protection. It occupies a very important position in the entire power industry. The high-voltage switch control cabinet is an electric power equipment used for power generation, transmission, distribution, power conversion and consumption of power system to play the role of on-off, control or protection. High-voltage electrical appliances are equipment used to achieve closing, breaking, protection, control, regulation and measurement in high-voltage lines. General high-voltage electrical appliances include switching appliances, measuring appliances and current-limiting and voltage-limiting appliances. Low-voltage appliances are high-voltage switch automatic control equipment for high-voltage electrical appliance detection. They can manually or automatically connect and disconnect circuits according to external signals and requirements to achieve switching, control, protection, detection, transformation and regulation of circuits or non-electrical objects. Components or equipment, control appliances can be divided into two categories: high-voltage control appliances and low-voltage control appliances according to their working voltage, with AC 1200V and DC 1500V as the boundary.

[0003] When using existing control equipment, it is impossible to determine whether there is damage, short circuit or leakage inside the switch before operating the main switch, and direct contact with the switch is likely to cause danger. In addition, high-voltage electrical switches are easily contaminated by dust and water vapor when exposed to the air for a long time, which reduces the service life of the switch and makes it easy for the switch to be damaged and leak. In addition, the control equipment usually fixes the lighting equipment in the cabinet. When repairing the electrical components in the control equipment, the lighting position of the lighting equipment cannot be adjusted, causing inconvenience in maintenance. Summary of the invention

Under the influence of gravity, the protective shell 22 rotates and leaks out the main valve switch body 11. When the detection is completed, the protective shell 22 can be rotated first to make it stick to the inner wall of the high-voltage switch automatic control device 1, and the first motor 31 can be reversed to make the sleeve plate 25 return to its original position, and the tooth plate 37 also returns to its original position. The limit rod 372 penetrates the protective shell 22, so that the protective shell 22 can be limited. The protective shell 22 can cover the main valve switch body 11 inside it to avoid water vapor and dust pollution;

[0046] When it is necessary to adjust the position of the lighting lamp 43, the limit screw 45 can be rotated first to disengage its end from the moving block 42 and also from one of the circular holes 44. The position of the lighting lamp 43 can be adjusted by moving the moving block 42. When it is adjusted to a suitable position, the limit screw 45 can be inserted into the other circular hole 44 and then connected to the threaded hole opened in the moving block 42, so that the limit can be easily adjusted.

[0047] When the device is moved to a suitable position through the universal wheel 12, the rotating disk 58 cooperates with the connecting rod 57 to rotate the double-headed screw 52. The rotation of the double-headed screw 52 can move the two rectangular sleeves 53 mounted on its outer surface. The supporting plate 55 can be moved downward through the rotating rod 54. After the position of the supporting plate 55 exceeds the universal wheel 12, the device can be supported, thereby improving the stability of the device during use.
