Description

Technical Field

[0001] This utility model relates to the field of switchgear, specifically to a visual high-voltage disconnect switchgear. Background Technology

[0002] A visual high-voltage disconnect switchgear is a high-voltage electrical device with visualization capabilities. It is mainly used to isolate power supplies in high-voltage circuits to ensure maintenance safety. The visualization components commonly include observation windows, which are made of transparent materials such as plexiglass, allowing direct observation of the open and closed states of the disconnect switch contacts. Some high-end products are also equipped with cameras to enable remote real-time monitoring. For example, the visual high-voltage disconnect switchgear for electrostatic precipitators uses infrared cameras to monitor the heating of the contact points of the disconnectors in real time and uploads the video signal to the host computer. However, the cameras currently used to observe the condition of the disconnectors inside the high-voltage disconnect switchgear are difficult to adjust in terms of angle and are inconvenient to install and remove, making it difficult to maintain them quickly in the future. Utility Model Content

Detailed Implementation

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0015] This utility model provides, for example Figures 1-11 The illustrated high-voltage disconnect switchgear includes a cabinet 1, a switch box 2 is installed inside the cabinet 1, a through hole 6 is opened on the front surface of the switch box 2, and a fixing plate 5 is fixed to one side of the front surface of the switch box 2 by bolts. A transparent cover 7 is fixed inside the fixing plate 5, one end of the transparent cover 7 extends into the interior of the switch box 2, and a camera 16 for monitoring the status of the switch knife inside the switch box 2 is installed inside the transparent cover 7 by an angle adjustment mechanism.

[0016] Furthermore, a sealing ring 8 is provided between the fixed plate 5 and the switch box 2 to improve the sealing performance between the fixed plate 5 and the switch box 2.

[0017] Furthermore, the angle adjustment mechanism includes a fixing ring 9, which is fixed inside the transparent cover 7. A rotating ring 10 is rotatably connected inside the fixing ring 9 via a bearing ring. Fixing blocks 11 are fixed on both sides inside the rotating ring 10. A fixing plate 12 is fixed on one side of the fixing block 11 by bolts. The camera 16 is mounted on the fixing plate 12, and the lens of the camera 16 is close to the transparent cover 7.

[0018] Furthermore, an angle adjustment mechanism for adjusting the angle of the camera 16 is provided on one side of the fixing plate 12; The angle adjustment mechanism includes a limiting frame 13, which is fixed to one side of the fixed plate 12. Movable movable blocks 19 are provided on both sides of the interior of the limiting frame 13. A lever 17 is connected to one side of the movable block 19. One side of the lever 17 extends to the outside of the limiting frame 13, and a rectangular groove for the lever 17 to move is provided on the outer wall of the limiting frame 13. A spring 18 connects the two movable blocks 19; Positioning rods 14 are fixed on opposite sides of the two movable blocks 19. The ends of the positioning rods 14 pass through the limiting frame 13. The inner wall of the fixing ring 9 is provided with a number of positioning holes 15 that match the positioning rods 14 in a ring array.

[0019] Furthermore, the end of the positioning rod 14 has a spherical structure.

[0020] Furthermore, the front surface of the switch box 2 is equipped with a lighting lamp 4 for illuminating its interior and an observation mirror 3 for observing the opening and closing of the internal switches. The lighting lamp 4 can illuminate the interior of the switch box 2 so that the staff can see the opening and closing status of the internal switches through the observation mirror 3.

[0021] Through the above technical solution: In use, the transparent cover 7 can be inserted into the switch box 2 through the round hole, and then the fixing plate 5 is fixed to the switch box 2 with bolts to ensure the stability of the transparent cover 7 (the shape of the transparent cover 7 is not fixed, and it is shown as a cuboid in this case. The transparent cover 7 and the fixing plate 5 are fixedly connected by bolts, and a sealing gasket is used to seal the connection. In addition, the transparent cover 7 and the fixing plate 5 can also be fixed by adhesive, provided that the adhesive is strong enough and has good sealing performance to prevent the leakage of sulfur hexafluoride gas inside the switch box 2). After the transparent cover 7 and the fixing plate 5 are installed, the fixing plate 12 and the fixing block 11 are fixed with bolts so that the camera 16 can be located inside the transparent cover 7. Next, press the two levers 17 inward to compress the spring 18. At this time, the two positioning rods 14 will be pulled out from the positioning holes 15 on both sides. Then, continue to squeeze the levers 17 and drive the fixing plate 12 to rotate. Since the fixing plate 12, the fixing block 11 and the rotating ring 10 are in a "whole state" at this time, the rotation of the fixing plate 12 will drive the rotating ring 10 to rotate inside the fixing plate 9, thereby quickly adjusting the position of the camera 16 to ensure that the camera 16 can be aligned with the position of the switch knife inside the switch box 2. Once the camera 16 reaches the designated position, release the lever 17. With the spring 18 resetting, the positioning rod 14 will re-enter the positioning hole 15, thus completing the position locking of the camera 16. Since the camera 16 is not directly installed inside the switch box 2, the subsequent maintenance and angle adjustment process of the camera 16 is extremely convenient. The power supply of camera 16 can be the same as that of the lighting lamp 4 in the disconnect switch cabinet (generally, the disconnect switch is equipped with a lighting lamp 4, and the specific power supply circuit of the lighting lamp 4 is existing technology, which will not be described in detail in this case).

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
