A lightning protection puncture grounding clamp

Abstract

The invention discloses a lightning-protection puncture ground clamp, which comprises a fixed ring, wherein a hollow cartridge is fixedly arranged at the bottom end of the fixed ring; a rotating shaft of which one end extends to the outside of the bottom end of the cartridge is movably arranged in the cartridge; locating mechanisms which are tangent with the rotating shaft are movably arranged at two sides of the cartridge; a winding blocking wheel is fixedly arranged on the rotating shaft; two parallel torsion springs are fixedly arranged in the fixed ring; a snap ring I and a snap ring II which extend to the outside of the fixed ring are fixedly arranged at one end of the two torsion springs respectively; and a clamping groove matched with the snap ring I is formed in the top end of the snap ring II. According to the lightning-protection puncture ground clamp, the snap rings are expanded by arranging the winding blocking wheel capable of rotating to pull a steel wire, the snap rings can be closed through use in cooperation with the torsion springs, and the lightning-protection puncture ground clamp can be more conveniently installed and used under the fixation of the locating mechanisms, does not fall off in use for a long period of time and is high in safety and convenience.

Description

technical field [0001] The invention relates to the technical field of electric power fittings, in particular to a lightning protection puncture ground clamp. Background technique [0002] In substations and various factories and mines, whether the status of power equipment is normal operation or maintenance, the quality of its grounding is directly related to the safety of the entire power system. [0003] However, the existing grounding clamps often have the problem of not being firmly fixed, and often fall off during use, which affects safety, and cannot play the role of lightning protection when lightning occurs, greatly reducing the service life of the grounding clamp. We propose a lightning protection puncture ground clamp to solve the above problems. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention provides a lightning protection puncture ground wire clamp, which has the ad...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a lightning protection puncture ground wire clamp, which has the advantages of lightning protection and no falling off during long-term use, strong safety and convenience, etc., and solves the problem of the existing ground wire There are many clips that are not fixed firmly, and they often fall off during use, which affects safety, and cannot play the role of lightning protection when lightning occurs, which greatly reduces the service life of the grounding clip.
