Abstract
In recent years, gas insulated switchgear (GIS) has been widely used in power systems. As an important part of GIS equipment, its operation reliability is directly related to the stability of electrical equipment operation. Therefore, analyzing the operating condition of electrical connection structures in GIS equipment is necessary. In this paper, the spring contact is taken as the research object, the electric field, thermal field, and flow field distribution were simulated, the surface of the spring contact after prolonged use was observed by scanning electron microscopy. It is found that the operating temperature of the spring contact is 339.07 K. When deterioration occurs due to poor contact, the temperature of the conductor can reach 415.59 K. In addition, the long-term operation will cause significant wear on the contact surface, which will degrade electrical contact performance. The research in this paper can provide a theoretical basis for the analysis of GIS overheating faults.
