A short-circuit grounding clamp with locking and 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 power grids and the requirements for safe operation of lines, power outage maintenance operations on high-voltage transmission lines have become more frequent. When the line is overhauled, in accordance with the requirements of the "Electrical Safety Work Regulations" and standardized operating procedures, immediately hang up the short-circuit grounding wire after checking the electricity, and then proceed with the work of defect processing. The short-circuit grounding clamp (also known as the wire terminal card) is an important component specially used to temporarily short-circuit and ground the power transmission wire after a power failure. Its reliable performance can ensure the safety of the high-voltage transmission line power failure inspection and prevent sudden power call...
