Abstract

Aimed at the ambiguity and randomness of the SF

high-voltage circuit breaker state evaluation index

a fuzzy comprehensive assessment method for the overall performance of SF

high-voltage circuit breaker based on cloud model is proposed. The state evaluation hierarchy model of SF

high-voltage circuit breaker

including mechanical characteristics

electrical characteristics

breaking wear

insulation characteristics and other characteristics

has been comprehensively established. Combined with the analytic hierarchy process and the entropy weight method

the combination weighting method is used to determine the combined weight of each indicator. The co

mbined weights of the indicators are modified by the variable weight formula. The ambiguity and randomness of the state parameters are processed by the digital features of the cloud theory

which established an association between the state characteristics and performance of the evaluation indicators. The example analysis shows that the method is simple and easy. And it can provide a theoretical basis for the state maintenance of SF

high-voltage circuit breaker.
