Quick Troubleshooting of Urban Substation Area

With the continuous improvement of urban construction level in China, the reliable operation of power distribution network has attracted more and more attention. However, in view of the high complaint rate caused by power failures, the problem of long power failure time in urban public transformation is found out. By investigating the outage time of public transformer in urban areas, we get the fact that the emergency repair time is long after the failure of public transformer in urban areas. In this paper, by sorting out the types of faults in the urban common transformer areas, the emergency repair time of each type of fault was queried and counted, and the reasons for the long emergency repair time of the common transformer areas were demonstrated and the long repair time of JP cabinet was deeply analyzed. It was determined that the reason for the long emergency repair time of JP cabinet switch fault was long. Through the research and development and experiment, anti-shedding hex socket and special screw fastening device were successfully made. After a lot of practical application, the time of emergency repair is greatly shortened, and the efficiency of emergency repair of failure and power failure in substation area is greatly improved, which has great value of popularization and application.
