Short-circuit ground clamp with locking anti-loosening function

Abstract

The invention relates to a short-circuit ground clamp with a locking anti-loosening function. The short-circuit ground clamp comprises a clamp body and a locking device, wherein the clamp body comprises a hook, two tongue pieces movably connected to the inner side of the hook and two tension springs arranged between the hook and the tongue pieces. The short-circuit ground clamp is characterized in that the locking device is a ratchet wheel non-return mechanism, the ratchet wheel non-return mechanism allows a conducting wire to enter the clamp body, and the conducting wire is restricted to retreat from the clamp body. The short-circuit ground clamp has the advantage that the locking device is added on the basis of an existing duck tongue type (double-tongue tensioning type) ground clamp without changing original operation habits, so that the short-circuit ground clamp has the characteristics of simple structure, sensitive actions and easy operation, and solves the risk that the existing ground clamp is likely to slide out of the conducting wire.

Description

technical field [0001] The invention relates to the field of electric safety appliances, in particular to a short-circuit grounding clamp. Background technique [0002] With the continuous development of the power grid and the requirements for safe operation of the line, power outage maintenance operations on high-voltage transmission lines are becoming more and more frequent. When performing line maintenance, according to the "Electricity Safety Work Regulations" and the requirements of the standardized operation process, immediately hang the short-circuit grounding wire after the electricity is checked, and then carry out the work of defect handling. The short-circuit grounding clamp (also known as the wire terminal clamp) is an important part specially used for temporarily short-circuiting and grounding the power failure transmission wire. The induced voltage generated by the equipment is harmful to the human body. [0003] At present, the short-circuit grounding clamps...
