Abstract
An evaluation model for vacuum circuit breaker is established based on grey correlation degree and TOPSIS method,and an evaluation index system,which consists of vibration signal,vacuum density,electrical endurance and contact temperature,is proposed considering typical faults of vacuum circuit breakers.The entropy weight method is applied to determine the weights of the evaluation indexes.The Euclidean distances and grey correlation degrees are calculated to describe the closeness between the evaluating samples and the positive or negative ideal solutions,and the samples are ranked according to their calculated relative closeness.Results of data analysis for a case study show that the proposed method reflects the operating status of a vacuum circuit breaker objectively and effectively compared to other method,so it may provide a reference for maintenance planning and policy of vacuum circuit breaker.关键词
