Electrical installation tool for overhead line fault indicators

Abstract

The invention discloses an installation tool for overhead line fault indicators. A support frame comprises two supports which are symmetrically arranged at the open end of an insulation cup, each support is hinged to the insulation cup, a connecting piece is arranged on the middle upper portions of the two supports and located on a plane intersected with the plane where the two supports are located, the supports and the connecting piece can swing together around the hinged joint of the two supports, two positioning protrusions in vertical distribution are arranged on the upper portions of the two supports respectively, the positioning protrusions and the connecting piece are positioned on two sides of the plane of the supports respectively, and the distance between the outer surfaces of the positioning protrusions is equal to or smaller than that between two support frames of one overhead line fault indicator. The supports with the positioning protrusions are added on the insulation cup of an existing fault indicator installation tool, so that a V-shaped clamping groove and a pull pin can be accurately positioned and forced to return accurately, returning of the pull pin is facilitated, and further installation success rate of the fault indicators is increased.

Description

Technical field [0001] The invention relates to an installation tool, in particular to a live installation tool for an overhead line fault indicator. [0002] Background technique [0003] At present, many bureaus have installed a considerable number of fault indicators in the power distribution overhead 10kV line. The structure of the fault indicator includes a bottle body for accommodating various electronic components at the bottom and two ears standing on the bottle body. The upper part of the support frame is provided with a through hole, and the through hole is provided with a pull pin that penetrates the two support frames. One end of the pull pin is provided with a positioning cap. The pull pin passes through the through hole of one support frame to the other The through hole of the support frame is provided with a tension spring on the pull pin rod between the positioning cap of the pull pin and the first support frame, and a V-shaped card slot is provided ...

AI Technical Summary

Problems solved by technology

But the actual situation is that due to the manufacturing process and other reasons: for example, the compression spring deviates from the center of the V-shaped slot, or the support frame is tilted and is not in an upright state, etc., it will cause an error in the return of the pull pin, so that the pull pin cannot be worn. Passing through another support frame, this will cause the fault indicator to not be installed correctly on the cable, drop damage, and even hit people.
