Background technique

The distribution network is an important part of the power system, responsible for the distribution and transmission of electric energy. Different from the transmission network, the distribution network has to extend from the substation to the end users, resulting in very complicated wiring methods and difficult management, which has become the main factor affecting the reliability of power supply. Therefore, when a fault occurs in the distribution network, how to quickly and effectively identify and deal with it has always been the focus of production and maintenance personnel.

Traditional distribution network line monitoring mainly relies on simple fault indicators, which can only give an alarm when there is a fault, but cannot monitor the line. The video monitoring part has been widely used in the main network, but due to the complexity of the power distribution lines and the difficulty in obtaining power, it has not been widely promoted. Even if there are some applications in the power distribution lines, it basically copies the use of the main network, a simple and independent routine Video photography cannot achieve linkage capture and fails to match the actual production and operation of the distribution line.

Timely monitoring and early warning of the operating status of distribution network lines can not only shorten the power outage time of users, but also reduce the power outage area and the waste of operating economic costs caused by power outages. It can also reduce the labor intensity of operation and maintenance personnel, and reduce the additional costs caused by line and equipment maintenance. Therefore, the vigorous research and development of the distribution line operation status monitoring device has extensive and far-reaching economic and social benefits.
