The Condition Based Maintenance Evaluation Model on On-post Vacuum Circuit Breaker

The safe operation of power supply equipments is closely related to the security of electric network. The planned maintenance of existing power equipments o cannot meet the needs of development of power system. To solve the problems in maintenance for vacuum circuit breaker, this paper build the equipment condition and risk assessment index system and bring out the outdoor on-post vacuum circuit breaker condition based maintenance evaluation model which based on Rough Set and Support Vector Machine according to the real condition. To prove the high accuracy of this method, a research which about the data of 100 Box-type substation in the distributing network of one power supply company is conducted in this paper.
