Abstract: The purpose of this paper is to improve the stability and reliability of power systems and analyze and deal with the common faults of isolating switches in substation primary equipment. The normal operation of the isolating switch is very important to ensure the power supply and the fault may lead to power supply interruption and safety accidents. Firstly, the structure, working principle, and function of isolating switches in the power system are summarized. Then, the fault types caused by mechanical, electrical, and environmental factors are listed in detail, and the fault analysis methods such as infrared thermal imaging and partial discharge detection are introduced. For all kinds of faults, the corresponding treatment measures are put forward, including the maintenance and adjustment of mechanical faults, the recovery of insulation performance of electrical faults, and the prevention and control strategies of environmental factors. The necessity of regular inspection and maintenance is emphasized, and preventive maintenance measures and contingency plans are proposed to reduce the failure rate. Through case analysis, the actual fault treatment process and cause analysis are shown, and the experience and lessons are summarized. Finally, the research results are summarized, and future development suggestions are put forward to provide guidance for power system operation and maintenance personnel and ensure the safe and stable operation of the power system.
