Railway power equipment in the long use process may have some fault problems affect the normal operation, so the railway unit should improve the attention to state maintenance technology, create a complete railway equipment state maintenance system, so that state maintenance technology can give full play to the application value in the railway power equipment management. This paper firstly analyzes the necessity of state maintenance of railway power equipment, and then discusses the measures to strengthen the maintenance management and maintenance of railway power equipment in order to have certain reference value for relevant research.展开更多
