Explore the verification and improvement method of insulation of 10~35kV high voltage switchgear

Abstract In the rapid development of China’s power system, number applications high-voltage switchgear is increasing. Every year, tens thousands are put into industry. Since performance and quality directly determines operation efficiency system has a positive impact on safety production effective supply grid scholars from all over world have gradually strengthened research insulation failure conducted verification analysis based practical cases. this paper, understanding status fault technology 10-35kV high voltage switchgear, according to representative accident cases, taking in certain area as an example verify analyze, finally forward improvement methods.
