Description

A 10kV distribution automation test platform

technical field

The utility model relates to the technical field of distribution network equipment maintenance, in particular to a 10kV distribution automation test platform.

Background technique

Distribution automation is an important means to improve the reliability of power supply, and it is also an important part of smart grid. With the construction of smart grids and the continuous deepening of the transformation of urban and rural power grids, the number of distribution automation lines is increasing year by year, and the number of distribution automation terminals is increasing. Distribution automation terminal equipment has been running continuously since it was put into operation. With the increase of running time, the problems and defects of automation terminal equipment have gradually increased. The main work of the second inspection team.

In the work of eliminating defects in distribution automation, the failure of remote control of distribution network automation equipment is mainly caused by the defects of primary equipment and secondary terminals. The distribution network control department needs to check and accept the work of eliminating defects. The method is to remotely control the "opening and closing" of the device again to check whether the terminal can be remotely controlled normally. However, when remote control the terminal, a switch cooperates with it to complete the remote remote control opening and closing, which will cause a power outage for the user. In order to ensure the power supply of the user, the defect acceptance of the remote control failure cannot be carried out. There is a chance to accept it, otherwise it has been put on hold. Therefore, in order to ensure the reliability of power supply, after the defect of remote control failure is eliminated, it has been unable to be checked and accepted, so that the terminal cannot be guaranteed to return to normal. When dealing with telemetry defects, the current output by the CT in the automatic switch cannot be measured by an instrument, so it cannot be determined whether the telemetry abnormality is caused by a terminal problem or an equipment problem. Generally, it is solved by replacing a new set of switches after a power outage, and reporting the power outage plan. The construction and replacement process takes a long time, resulting in defects that cannot be eliminated in time. There is no better way to solve the problems that the automation terminal cannot be remotely tested and the CT output current cannot be directly measured in the secondary fault elimination of power distribution. Except for power failure, there is no better way to solve these problems. Unnecessary losses due to power outages.
