Abstract

The development of the power system puts forward higher requirements for the reliability of the highvoltage switch products.The SF

gas leakage is one of the most important factors that cause defects and breakdown of highvoltage switch.Research on reliability data analysis method of highvoltage switchgear has been carried out based on SF

gas leakage service data of 110 kV circuit breaker.The statistical analysis of service data shows that the SF

gas leakage data can be described by the Weibull distribution model.Furthermore

parameters of the Weibull distribution are estimated.The resultsare compared with the statistical histogram

and the effectiveness of the paramete

r estimation resultisverified.Based on this

the life evaluation of SF

gas leakage of highvoltage switchgear is analyzed and the basic operation and maintenance strategy for the sealing structure of high voltage switchgear is supplied.
