Compared with the traditional air-insulated switchgear, the air-insulated switchgear has the characteristics of small floor area, good safety performance, high reliability, long overhaul period and the like, so that the GIS is widely used along with the rapid development of the construction of the electric power industry in China.
The safe operation of the GIS is crucial to the stability of the power system, and the detection work of the GIS must be emphasized and strengthened to ensure the safe operation of the GIS. Because the field intensity in the GIS is very high, when some defects exist in the equipment, partial discharge can occur during running, and ultrahigh frequency electromagnetic waves and sound wave signals can be excited. GIS insulation fault mainly is in the production of products, field installation and operation process, and GIS air chamber internal defect leaves and leads to the emergence of trouble in service.
