With the continuous development and progress of society, China's urban power grid has undergone great changes, and most cities have formed or are forming from more power load intensive areas. In the past, the power supply from the substation 12/24kV line (or branch line) to the direct user has been difficult to meet the requirements of urban development. Therefore, a new power supply method is produced by opening and closing the power supply to the user. However, with the intensification of urban densification, some of the original civil type openings and closures have been limited by land and urban planning, so a more advanced and practical outdoor intelligent openings and closures (outdoor ring cabinet) has emerged. This opening and closing house does not need civil construction and occupies less area, the configuration is very flexible and the power supply mode is more reliable, the construction and installation, debugging time is greatly shortened, and the overall cost is reduced.Intelligent opening and closing (outdoor ring network cabinet) is the use of foreign advanced technology, the 12/24kV switchgear, circuit breaker, load switch. Current and voltage backbone, 12kV power supply PT, switching station FTU, RTU, communication control terminal (CCU), 12/24kV metering and automatic meter reading, USP power supply and indicating instrument are installed and adjusted into a movable, sealed and moisture-proof stainless steel box. Thus, the integration and modular assembly of the primary and secondary systems of the urban distribution network are realized, the construction period is shortened, and the reliability of the urban power network operation is greatly improved.
