Abstract

The invention discloses an overhead line live part verification grounding loop line clamp insulating protection cover detaching tool which comprises an insulating awl, an insulating clamp, an insulating handle, an insulating hollow rod and an operation transmission mechanism, wherein the insulating awl is fixedly connected with the outer surface of the insulating hollow rod; the insulating clamp is connected with one end of the insulating hollow rod; the insulating handle is connected with the other end of the insulating hollow rod; the insulating handle is connected with the insulating clampthrough the operation transmission mechanism. By adopting the overhead line live part verification grounding loop line clamp insulating protection cover detaching tool disclosed by the invention, a live part verification grounding loop line clamp insulating protection cover can be safely detached when an overhead line is electrified, and a premise that influence of torque caused by torsion of a live part verification grounding loop to safe operation of a lead is eliminated in time can be created; an arc-protection fitting insulating protection cover can be safely detached, and conditions required for eliminating influence of amplified discharge gaps caused by torsion of an arc-protection tool to safe operation of the lead in time can be created; moreover, an operator can be prevented fromelectric shock, and safety can be ensured.

Description

technical field [0001] The invention relates to the technical field of high-voltage wires, in particular to a tool for removing an insulating shield of an overhead wire electrical inspection grounding ring clip. Background technique [0002] During the short-circuit fault process of 10kV insulated overhead lines, there will be mutual attraction or mutual repulsion interaction between the conductors, which will cause the conductors to twist and deform. Some torsional deformations exceed the range of elastic deformation. When the interaction between the wires disappears, the original shape cannot be restored. This phenomenon causes the electrical testing grounding ring installed on the wire to deflect around the wire itself, and the electrical testing grounding ring on the wire Also can't return to the state perpendicular to the ground, this not only affects the appearance of the line, but also adds additional torque to the wire. When the line is powered off and the ground wir...
