Problems solved by technology
This method can only be used for high-voltage insulation tests between phases A and B. When doing insulation tests for phases B and C, the test tooling on the other side needs to be disassembled for phase change, reassembled and needs to be evacuated and inflated again. Every time the outdoor station is disassembled, a crane must be used. Repeated disassembly, charging and deflation make it take up to 3 working days to complete the insulation test of the entire power station. The FS6 gas consumption reaches about 4 bottles, and the insulation test workload is heavy. Low efficiency and high cost

Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] Such as figure 1 As shown, the insulation test tool for the cable outlet of the gas-insulated metal-enclosed switchgear in this embodiment includes a rotating conductive rod 1, a moving contact 2 and three static contacts 3, and the moving contact 2 is installed on the rotating conductive rod. 1, three static contacts 3 are arranged at intervals on the rotation path of the movable contact 2, and each static contact 3 is equipped with a telescopic grounding rod assembly 4. When in use, the movable contact 2 can be driven to A and keep the static contact 3 of phase A separated from its telescopic ground rod assembly 4, and the telescopic ground rod assemblies 4 of B and C keep in contact with their static contact 3, and then connect phase A High-voltage line, B and C two-phase grounding wires, so that the insulation test of the ...

The invention discloses an insulated test tooling for a cable outgoing line of a gas insulated metal-enclosed switchgear. The insulated test tooling comprises a rotary conducting rod, a moving contact and three fixed contacts, wherein the moving contact is arranged on the rotary conducting rod; the three fixed contacts are arranged on a rotating path of the moving contact at intervals; and the fixed contacts all are provided with telescopic ground rod assemblies. The insulated test tooling has the advantages of being simple in structure, high in test efficiency, low in cost and the like.
Description
technical field [0001] The invention relates to a gas-insulated metal-enclosed switchgear, in particular to an insulation test tool for cable outlets of the gas-insulated metal-enclosed switchgear. Background technique [0002] Using the existing insulation test tool for testing, it is necessary to install a test tool on the interval between two gas insulated switchgears (GIS) at the same time. For example, when doing the insulation test of the A-phase switch body, the B-phase Grounded, C phase is a suspended conductor. This method can only be used for high-voltage insulation tests between phases A and B. When doing insulation tests for phases B and C, the test tooling on the other side needs to be disassembled for phase change, reassembled and needs to be evacuated and inflated again. Every time the outdoor station is disassembled, a crane must be used. Repeated disassembly, charging and deflation make it take up to 3 working days to complete the insulation test of the ent...
