Description

technical field [0001] The invention relates to the technical field of high-voltage electrical testing, in particular to a device and method for simulating a real GIS three-position switch air-gap discharge testing system. Background technique [0002] At present, in the field of electrical engineering, GIS (closed gas insulated combined electrical appliances) three-position switch is widely used due to its compact structure and reliable connection. The three-position switch is usually located in the closed air chamber on the side of the outgoing line and the bus bar. There are many metal components in this area, and the operating mechanism is complexly related to each other. It is used as the connecting center of the isolating switch and quick grounding, and the operation is frequent. The metal link and the operating solid Air gaps are easy to occur between insulations, and even because of poor workmanship, there are cavities inside solid insulating devices. Such defects ac...
