Problems solved by technology

The assembly weight of the existing double-split wire fixture is about 15-25kg, that is to say, the No. 1 electrician must bear the force of nearly 100 kilograms to meet the requirements of indirect assembly of live fixtures, so the existing technology is difficult to complete the tensile double Ground Potential Replacement Operation of Vertically Arranged Strings of Insulators

Abstract

The invention discloses a decomposition type tensioning resistant double string vertically-arranged insulator string ground potential replacing clamping apparatus which comprises a front clamp, an insulating pull rod, a fastening screw rod and a rear clamp. The front clamp can achieve long-distance indirect installation and is blocked. The insulating pull rod is matched with the front clamp in use, a positioning pin is arranged on an end portion of the insulating pull rod and is perpendicular to a rod body of the insulating pull rod, and the front clamp is wing-shaped. Through holes matched with the insulating pull rod are formed in two ends of two side wings of the wing-shaped front clamp, and grooves extending along the axial direction of the through holes and enabling the positioning pin fixed on the insulating pull rod to penetrate through are formed in hole walls of the through holes. The decomposition type tensioning resistant double string vertically-arranged insulator string ground potential replacing clamping apparatus has the advantages that the whole set of the clamping apparatus is decentralized to elements in a decomposition type and is installed on vertically-arranged double bundled conductors which operate with electricity, and the problem that ground potential cannot operate with the electricity through construction process in the past is solved.

Description

technical field [0001] The invention relates to a tension-resistant double-string vertically arranged insulator string earth potential replacement jig, in particular to a decomposed tension-resistant double-strand vertically arranged insulator string earth potential replacement jig. [0002] Background technique [0003] The most critical factor in the ground potential live work replacement operation is the overall weight of the clamp. The fastened ground potential live work clamp is usually assembled as a whole, and then clamped into the cross arm and wire end for operation. At this time The problem that arises is that the weight of the assembled jig is not light. The heavier it is, the more difficult it is to construct. The assembly weight of the existing double-split wire fixture is about 15-25kg, that is to say, the No. 1 electrician must bear the force of nearly 100 kilograms to meet the requirements of indirect assembly of live fixtures, so the existin...
