Device Status Maintenance Applied Research In Shijiazhuang Power Supply Company

With the rapid expansion of the grid size and the sharped number of grid equipment, regular maintenance workload of the dramatic increase in the shortage of maintenance personnel have become increasingly prominent,regular maintenance mode can not adapt to the grid development and the technological progress of Shijiazhuang.To explore the maintenance of applications based on the status of device mode,inproving the level of network reliability,and resonable to reduce the equipment repair and maintenance costs,inprove labor productivity, is the inevitable demand of Shijiazhuang, the powe company to achieve the development goals of a strong three excellent company.In this paper, the actual situation of the substation operation, the device status information acquisition technology to analyze the state of maintenance and online monitoring, condition based maintenance model proposed for grid equipment status quo in Shijiazhuang. Take the main transformer for example, analysis of transformer equipment defects and failure law, put forward the overall strategy of the main transformer equipment condition overhaul the health records of the transformer equipment to develop a maintenance cycle and project.Elaborate equipment condition based maintenance technical solutions for information management system, computer network technology, the development of condition based maintenance information management system, construct equipment condition based maintenance management, analysis, intelligent decision support platform to achieve with the production management system informnation resources sharing.The comparative analysis of the reliability index of the power transmission facilities, maintenance costs, equipment operation and defect data, completely solve equipment maintenance "minor ailments Dodge, disease-free governance" blind phenomenon, verify the condition based maintenance to improve equipment reliability, reduce equipment maintenance costsimprove the level of grid operation and the company’s overall efficiency is of great significance.
