Research on Fault and Maintenance Measure of Power Transformer
Power transformer is the key equipment in power system,and its operation will directly affect the normal operation of power network.This paper mainly analyzes the common fault types of power transformers and their causes,including oil leakage fault,overheating joint,winding fault,etc.,and analyzes modern detection methods such as dissolved gas analysis technology,infrared diagnosis,winding deformation monitoring and so on.These power transformer maintenance technologies play an important role in fault diagnosis,prevention and maintenance.By using this technology flexibly,the operation safety of transformers can be effectively improved.
