Reliability Growth Model of Electric Equipment and Its Application in 220 kV Electric Equipment
A reliability growth model for electric equipment is presented. Ways are given for estimating and fitting checking the model＇s parameters and the analysis results are provided of the reliability growth of six kinds of 220 kV electric equipment by use of the reliability growth model, including the 220 kV transformers, circuit breakers, isolating switches, surge arresters, current transformers and voltage transformers. The verification results of on-site operation reliability data show that this reliability growth model conforms to the reliability growth tendency of the six kinds of 220 kV electric equipment in China; the reliability of the domestic made electric equipment appears in growth tendency; and the improving measures taken by the power companies are effective. This reliability growth model is small in relative error and high in prediction accuracy and can be used to predict the reliability＇ s change tendency of the electric equipment in the future 10 years.
