Recently, in the Jiayuan urban community in Jiaxing City, several electric power workers opened the cable manhole covers one by one, and held identification instruments, locators, cameras and other equipment to locate and digitally name each cable in the cable well. In the past few days, the staff went to each community to conduct a detailed “dissection” of each cable well, so as to improve the cable line account.
According to the squad leader of the cable inspection team in the power distribution inspection room of Jiaxing Power Supply Company, in recent years, most cables in the urban area of Jiaxing have a long service life and a high incidence of cable failures. They are relatively long, which brings great pressure to the emergency repairs of the team members, and reduces the reliability of power supply of the power grid at the same time. To this end, since October, the cable inspection team in the power distribution room has actively carried out the digital census of the cables of the medium-voltage distribution network, combining the digital cable census with the standardized emergency repair platform to quickly and accurately determine the section and point of the accident, greatly shortening the time Accident emergency repair time, improve the accuracy of the user’s power supply scheme.
In addition, the distribution network management has the characteristics of many points, wide area and large quantity. After the digitalization of the cable network, the cables and cable wells will be labeled “electronic label”, which covers the number of pipes in the well, photos, road sections, the size of civil structures and the properties of each cable section. Once a fault occurs, its location can be tracked through electronic tags, which greatly improves the efficiency of line fault handling.
In the future, through the digital census of the urban cable network, the census of about 400 kilometers of high-voltage cables and more than 6,000 cable wells in the urban area will be completed, and a clear, standardized and standard urban underground cable network map will be formed.
