Description

technical field [0001] The present invention belongs to sulfur hexafluoride (SF 6 ) Technical field of on-line monitoring of insulation status of gas-insulated electrical equipment, specifically related to SF 6 Simulation experiment method for overheating failure of contact surfaces of gas-insulated electrical equipment. Background technique [0002] SF 6 Gas-insulated electrical equipment, in SF 6 As an insulating medium, gas has the advantages of high dielectric strength, stable operation, small footprint and small maintenance workload. It is more and more widely used in power systems, especially in the construction and transformation of large and medium-sized city power grids. However, judging from the operating conditions in recent years, the inevitable internal defects will still cause faults and continue to expand with the increase of operating time. Once a fault occurs, the SF 6 Due to its fully enclosed combined structure, gas-insulated electrical equipment makes...
