Analysis of Several Fault Cases and Rectification Measures for GIS Circuit Breaker Switch Operations in Substations

This paper discusses the basic structure and working principle of GIS circuit breakers, and provides an in-depth analysis of several typical switching faults, including issues such as the fracture of the main drive shaft pin and faults caused by the spring mechanism. The paper also presents methods for fault handling and optimization strategies for operation and maintenance. Through the analysis of several case studies, the paper aims to offer insights for addressing similar fault issues, with the goal of improving the reliability and stability of GIS circuit breakers.
