Background

When the existing GIS circuit breaker is used for testing loop resistance, the circuit breaker, the isolating switch and the two-end grounding disconnecting links are required to be arranged at switch-on positions, then the grounding flat iron at the leading-out ends of the two-end grounding disconnecting links is unfastened, and loop resistance testing pliers are directly clamped at the leading-out ends of the two-end grounding disconnecting links for testing. Because GIS circuit breaker ground connection switch leading-out terminal department is arc shape structure basically, adds the size great, leads to the contact of return circuit resistance test pincers not good. The solution adopted on site is that the antirust paint on the surface of the tank body edge of the leading-out end of the grounding switch is polished by a file, but poor contact of a test clamp often occurs, so that test data is abnormal. In addition, as the antirust paint on the surface of the GIS tank body is polished off, the service life of the GIS tank body is seriously influenced because the outdoor GIS tank body is directly exposed.
