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

Abstract

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