【Abstract】The continuous improvement of power technology and the accelerating development of power engineering have made Chinas power grid industry flourish. The operating voltage level of power grid systems has been continuously improved, and the scale of the network has been continuously expanding. In recent years, China has formed a Large-scale regional power grids, including North China. The stable operation of Chinas power grid not only has a positive impact on the rapid development of Chinas power industry, but also lays a technical foundation for the stable operation of Chinas economy, and also provides favorable conditions for Chinas socialist modernization. High-voltage isolation switch can effectively promote the stable operation of Chinas power grid, and thus ensure the steady development of Chinas economy. However, there are some faults in the high-voltage isolation switch that hinder its normal operation. This study describes the mechanical failure and its diagnostic techniques.
