Description

technical field [0001] The invention relates to the field of insulator measurement, in particular to a device and method for measuring the surface resistivity of a GIS pot insulator. Background technique [0002] For more than 30 years, Gas-Insulated Switchgear (GIS, Gas-Insulated Switchgear) has shown high reliability, which is attributed to the packaging of various components and the application of excellent insulating materials (such as SF6) and epoxy resin filled Basin insulators. [0003] In GIS insulation breakdown accidents, most of them are surface breakdown of pot insulators. Excluding the factors of material aging due to long-term work, the main reason for the breakdown along the surface is that the field strength of the electric field along the surface is the most concentrated, and the second is because the surface resistance of the pot insulator is reduced after the surface is polluted and the field of the electric field along the surface Strong further concent...
