Abstract

As the parameters for mechanical life estimation of a high voltage circuit breaker are random and fuzzy

the random fuzzy theory is applied to the estimation. Considering the random and fuzzy distribution characteristics of the mechanical life evaluation parameters

mechanical life testing of a high voltage circuit breaker was conducted in this study

triangular fuzzy variables were introduced

and curve fitting method was adopted to obtain the random fuzzy distribution function of the mechanical life evaluation parameters of high voltage circuit breaker. Subsequently

a residual mechanical life model of high voltage circuit breaker was established in dual-uncertain condition. Test result shows that the proposed model can objectively and effectively evaluate the mechanical life of high voltage circuit breakers.
