Method for processing HGIS device leakage defect by door type frame settlement breaker method

A method for processing the HGIS device leakage defect by a door type frame settlement breaker method is characterized in that (1) gas recovery is required before disassembling the air chamber neededto be maintained, and the disassembled air chamber needs to be evacuated and then dropped to zero gauge pressure; (2) a support is needed to reliably support the equipment above the breaker; (3) afterthe above two tasks are completed, the vacuum state of the gas chamber is disassembled and the circuit breaker mechanism is disconnected from the cable and the meter valve; (4) the basin-type insulator of the fault part of the circuit breaker is detached, and the basin-type insulator is replaced; (5) the lifting rope and the hand-pulling hoist are adjusted again, and the circuit breaker is horizontally hoisted; and (6) the new circuit breaker after being assembled can be kept at the same height as the circuit breaker before the detachment, the adsorbing agents in the air chambers at the two sides of the circuit breake
