Abstract :
High-voltage circuit breakers are important electrical equipments which play the role of protection and control in the power network. In order to make the power system operate in a stable and reliable way, it is of great significance to make online fault diagnosis of High-voltage circuit breakers. In this paper, the improved D-S evidence theory for data fusion method was studied and used in high-voltage circuit breakers fault diagnosis when the evidences from different types of sensors have large conflicts. The results proved that the method improved the diagnostic accuracy, and had some practical value.
