The grounding switch of the high-voltage switchgear is provided with an insulating rod, a guide block, a handle and a transparent cover. When grounding is required, the handle is pushed upward, the guide block is plugged into the conductor block and energized, and the transparent cover can effectively prevent the device from causing harm to the staff in the event of an accident. The rain shield and the rain guide groove are provided to effectively discharge rainwater through the rain guide groove to prevent rainwater from eroding the device.

[0004] In the above scheme, by setting up components such as rain shields and boxes, the device can be protected, rain can be prevented from eroding the device, and a sealed protective structure can be formed for the device. However, since the device will generate a lot of heat when in use, and a sealed structure is formed inside the box at this time, and no components for dissipating the internal heat are installed, it is easy for the heat inside the device to not be discharged to the outside in time, which will affect the normal operation of the device and cause dangerous situations. For this reason, we provide a grounding switch for high-voltage switchgear to solve the above problems. Utility Model Content

[0028] A switch body 4 is installed inside the outer box 1, a grounding wire 14 is connected inside the switch body 4, a grounding module 15 is installed outside the grounding wire 14, and components such as conductor blocks and guide blocks are installed inside the switch body 4 to connect the lines. A fixing plate 5 is installed outside the switch body 4, and the switch body 4 can be installed and fixed through the fixing plate 5.
[0029] The inner wall of the outer box 1 is fixedly connected with a fixing groove 17, and the interior of the fixing groove 17 is a convex hollow structure. The inner wall of the fixing groove 17 is slidably connected with a moving plate 18. Through the connection between the moving plate 18 and the fixing groove 17, the moving plate 18 can be stably moved inside the outer box 1, and the moving plate 18 is arranged up and down inside the fixing groove 17 for sliding.
[0030] The outer surface of the movable plate 18 is fixedly connected to a limit rod 19, and the outer surface of the limit rod 19 is slidably connected to the inside of the fixed plate 5. Four groups of limit rods 19 are provided, and the four groups of limit rods 19 are distributed in pairs on the left and right sides of the switch body 4. The port directions of the upper and lower groups of limit rods 19 are opposite. The fixed plate 5 can be fixed by the limit rod 19 when installing, and the fixed plate 5 can be propped up by fixing the fixed plate 5 toward different limit rods 19. At this time, the fixed plate 5 controls the switch body 4 to be stably fixed on the outside of the fixing groove 17, and the overall connection is relatively stable.
[0031] The inner wall of the outer box 1 is fixedly connected to a support plate 20, and a double-headed screw 21 is rotatably connected inside the support plate 20. A rotating handle is installed outside the double-headed screw 21, and the double-headed screw 21 can be driven to rotate by the rotating handle. The outer surface of the double-headed screw 21 is threadedly connected to a control plate 22, and the outer surface of the control plate 22 is fixedly connected to the outer surface of the movable plate 18. When the double-headed screw 21 is rotated, the control plate 22 can be driven to move up and down, and multiple groups of control plates 22 can be driven to move separately at the same time, and the limit rod 19 can be further controlled to move to fix the fixed plate 5.

[0033] A ventilation hole 6 is opened inside the outer box 1, and a radiator 7 is installed inside the outer box 1. Multiple sets of fans are installed inside the radiator 7, which can increase the air circulation speed inside the outer box 1 and effectively dissipate the heat inside the outer box 1.

A temperature sensor 16 is installed inside the outer box 1. The temperature sensor 16 can monitor the temperature inside the outer box 1. The filter plate 10 can filter the air entering the outer box 1 to prevent dust from entering the outer box 1 and being adsorbed on the outside of the switch body 4, thereby preventing dust from entering the switch body 4 and affecting the normal operation of the switch body 4.
[0035] The interior of the card plate 8 is slidably connected with a wedge block 11, and the outer surface of the wedge block 11 is slidably connected to the interior of the fixing frame 9.

When installing the filter plate 10, the fixing frame 9 can be directly placed into the interior of the card plate 8. At this time, the wedge block 11 will enter the interior of the fixing frame 9 under the action of the spring 12. The fixing frame 9 can be fixed by the wedge blocks 11 arranged up and down. When the filter plate 10 is disassembled and replaced, the fixing frame 9 can be disassembled by directly pulling the handle outside the fixing frame 9, and the installation and disassembly are very convenient.
[0036] Working principle: When installing the switch body 4, first rotate the double-headed screw 21. At this time, the double-headed screw 21 can drive the control plate 22 to move, and the movable plate 18 can be controlled to move up and down. The limit rod 19 is controlled by the movable plate 18 to enter the interior of the fixed plate 5. At this time, multiple groups of fixed plates 5 can be stably fixed by the limit rod 19. When dismantling, the double-headed screw 21 can be rotated in the opposite direction. At this time, the limit rod 19 will be separated from the fixing effect on the fixed plate 5, and the switch body 4 can be quickly dismantled. The radiator 7 can effectively dissipate heat inside the outer box 1. By setting the filter plate 10, the air entering the outer box 1 can be filtered to prevent dust in the air from entering the interior of the switch body 4 or being adsorbed on the outside of the switch body 4. When replacing the filter plate 10, just pull the fixing frame 9 directly. Under the action of the spring 23, the wedge block 11 can fix the fixing frame 9, which is convenient for installing and replacing the fixing frame 9.
