Embodiment

[0033] Embodiment: The technical problem to be solved in this embodiment is: for the structure of GIS equipment, after applying the auxiliary tool, the tester can test the equipment when the equipment is powered off or charged. The rod hangs the test wire clip on the inlet and outlet bushings of the test loop, and the loop resistance tester is used to complete the loop resistance test of the GIS equipment. One is to avoid misoperation accidents caused by frequent operation of circuit breakers, isolating switches, grounding switches and other equipment when the two sets of grounding switches on the circuit are connected to the circuit to be tested; the other is that testers can operate on the ground, Eliminate the need for climbing operations to prevent the risk of falling from high altitudes; third, testers can complete the test work when the equipment is powered off or charged, and operate on the ground, which increases the safety distance during operation and prevents persona...

Abstract

A GIS equipment loop resistance test auxiliary tool and an electric power construction enforcement method belong to the power transmission and transformation equipment operation and disaster prevention technology fields, aim to carry out the GIS equipment loop resistance testing works, thus solving the safety installation test wire clamp problems; the GIS equipment loop resistance test auxiliary tool comprises a hooked wire clamp and an insulation rod, and said two parts are connected through a sawtooth engaged swivel joint; the hooked wire clamp body is used for clamping a bended hooked insulator of the lead wire; the inner bending side is provided with a conductive material making contacts with the lead wire; a voltage line and a current line respectively electrically connected with theconductive material as test wires, and led out from the tail of the hooked wire clamp body.

Description

technical field [0001] The invention belongs to the technical field of power transmission and transformation equipment operation and disaster prevention, and relates to an auxiliary tool for testing loop resistance of GIS equipment. Background technique [0002] Due to its simple structure and convenient maintenance, GIS equipment has been widely used in power grids in recent years. Due to the large number of GIS equipment manufacturers and various forms and structures, the grounding side of the GIS grounding switch is not insulated from the shell, and the two circuits on the circuit cannot be used. When the group grounding switch is connected to the circuit to be tested for measurement, it is necessary to inject current from the inlet and outlet bushings for measurement. At this time, it is necessary for the test personnel to climb up to the inlet and outlet bushings on both sides of the GIS equipment, and manually install the test wire clamp for measurement. Due to the co...
