Problems solved by technology

However, for the 500kV line, the first three types of clip structures are not reasonable, and they are easy to fall off, making the working point lose protection
Although the spiral type can ensure reliable grounding, using it is labor-intensive, inefficient, and difficult to operate, and it is easy to cause construction personnel to sometimes not operate according to safety regulations, and there are certain safety risks

Abstract

The discloses a self-locking wire end earthing clamp which comprises a wire holder main body, a sub wire clamp and an angle adjusting mechanism, the earthing clamp provided by the invention utilizes a resetting self-lock principle to realize the purpose of clamping high-pressure wire, a clamp head is splayed and closed through only drawing back and relaxing a bracing wire, thereby thereby quicklycompleting the clamping of the high-pressure wire and loosen action, and operation is very simple; in addition, the earthing clamp is provided with the angle adjusting mechanism, the angle adjusting mechanism is utilized to regulate an angle between the wire clamp and an operation rod according to the requirements, thereby adapting to relative position variation of an operator and the tested high-pressure wire.

Description

technical field [0001] The invention relates to a high-voltage wire detection tool, in particular to a self-locking wire end grounding clip. Background technique [0002] The grounding clamp at the wire end is a safety device used to temporarily short-circuit and ground the power-off transmission wire. Its function is to prevent the harm to the human body caused by the sudden incoming power or the induced voltage generated by the adjacent high-voltage live equipment during the maintenance of the high-voltage transmission wire. At present, the clamps used by various power grid companies mainly include double tongue type, flat type, impact type and spiral type. However, for the 500kV line, the first three types of clip structures are not reasonable, and they are easy to fall off, making the working point lose protection. Although the spiral type can ensure reliable grounding, the use of it is labor-intensive, inefficient, and difficult to operate, and it is easy to cause cons...
