摘要
Abstract
Vacuum switch cabinet is one of the most important equipments in power distribution system,so its state has significant influence on the safety of the distribution network and the power quality at customs side.However,the information for condition assessment of distribution switch cabinet is insufficient,and the assessment model is not dynamic.In this paper,a vacuum switch cabinet condition assessment model based on multi-source information fusion is proposed.This model includes such information as ultrasound values,TEV values,infrared temperature,vacuum degree,insulation resistance and mechanical parameters.The vacuum switch cabinet is divided into vacuum circuit breaker,buses,and outlet cable for condition assessment.The environment information,operation information and position information of the vacuum switch cabinet are also taken into consideration.Moreover,membership functions and proportional model are employed in the condition assessment.Then Bayes conditional probability model is used to predict the future condition of the vacuum switch cabinet.In addition,examples are given to prove the validity of the proposed vacuum switch cabinet condition assessment model.Compared with conventional probability calculation model,the proposed model shows better consistency with operation condition of electric power equipments.关键词
