[0002] Cable grounding boxes are key equipment for ensuring the safe operation of high-voltage cables. They are mainly used to limit induced overvoltage and fault overvoltage of the cable's metal shielding layer and sheath, protect the cable sheath, and provide a safe grounding path. It is necessary to regularly check the appearance of the grounding box for damage and corrosion, check the connection of the grounding terminals for looseness and oxidation, check the operating status of the cable sheath protector for signs of overheating, discharge, or other abnormalities, test the grounding resistance, and ensure that the grounding resistance value meets the requirements. They are installed near the cable terminal and must meet the environmental requirements of -40 degrees Celsius to +40 degrees Celsius. Regularly checking the appearance, connections, and grounding resistance ensures that the insulation and withstand voltage performance meet the standards, which is an important guarantee for the safe operation of cables.

[0003] In power transmission and distribution networks, especially urban underground cable systems, dense cable channels in large industrial and mining enterprises, and critical facilities requiring high-reliability power supply, cable grounding boxes play a crucial role.

This instrument is an environmental monitoring component that displays the temperature and humidity values ​​inside or near the distribution box in real time. A support column 3 is fixedly installed at the bottom of the box bottom plate 29, forming a lifting support structure. A support column 4 is slidably connected to the outer wall of the support column 3, allowing the support column 4 to extend and retract along the support column 3, thereby changing the overall height. A lifting base 5 is fixedly installed at the bottom of the support column 4. This base serves as a load-bearing component of the entire distribution box and has a large contact area to enhance stability. A screw 6 is threadedly connected to the top of the lifting base 5 for fixing it to the ground.

[0043] Working principle: When maintenance is required, the handle 16 is rotated, and the handle 16 is rotatably connected to the locking block 17, so that the handle 16 is separated from the locking slot 14 to unlock the cabinet door. Subsequently, the locking block 17 will automatically return to its original position because it is rotatably connected to the handle 16. After the cabinet door is unlocked, the cabinet door panel 8 and the side panel 26 are rotatably connected by the hinge 12, so they can be opened 90 degrees. The side panel 26 and the cabinet back panel 1 are rotatably connected by the hinge 28, so they can be opened further.

[0044] When a cable needs to be connected, the cable should be connected to the conductive mechanism 2. The cable connector should be directly inserted into the clip 203 on the copper busbar 202. Because the clip 203 is rotatably connected to the copper busbar 202, the clip 203 will press the sliding post 204 into the conduit 206. After insertion, the sliding post 204 in the copper busbar 202 will return the clip 203 to its original position through the spring 205. Then, the surge arrester can be quickly installed and removed through the guide rail 208, thereby completing the quick cable connection.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
