Description

Technical Field

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

[0002] In power systems, high-voltage switchgear is a crucial device for controlling and protecting high-voltage electrical equipment. When performing maintenance, repairs, or other operations on high-voltage switchgear, the equipment may still carry residual charge. If this residual charge is not released promptly, it can pose a significant threat to the safety of operators, potentially leading to electric shock. Even after the power supply to the high-voltage switchgear has been disconnected for a period of time, a large amount of charge may still be stored internally due to factors such as capacitance. Therefore, a grounding wire for high-voltage switchgear is required.

[0003] The existing patent document with technical announcement number CN217281642U provides a special grounding wire conductive terminal device for switch cabinets that can effectively improve the grounding reliability of switch cabinets after the grounding wire is installed without affecting the installation of the grounding wire. It includes: a clamp body with a grounding slot; a grounding wire electrically connected to the clamp body; and a clamping assembly including a conductive fixed clamping plate, a conductive movable clamping plate, an elastic element, and a clamping opening formed between the conductive fixed clamping plate and the conductive movable clamping plate located in the grounding slot. The conductive fixed clamping plate is fixed in the grounding slot, and one end of the conductive movable clamping plate near the slot opening is hinged to the inner wall of the grounding slot. The other end of the conductive movable clamping plate rotates towards the conductive fixed clamping plate under the action of the elastic element. The conductive movable clamping plate is electrically connected to the clamp body via a flexible wire. However, the CN217281642U technology is not convenient for quick fixing of the device during operation, is not convenient for storing excess wires, and is prone to collision and pulling that causes it to fall off. Therefore, there is an urgent need for a grounding wire for high-voltage switchgear. Utility Model Content
