Outdoor Ring Main Unit 12-40.5KV

Overview
With the continuous development and progress of society, my country's urban power grid has undergone tremendous changes. Most cities have formed or are forming more power load-intensive areas. The power supply from the substation 12/24kV line (or branch line) to the direct user in the past can no longer meet the requirements of urban development. Therefore, a new power supply method has emerged to supply power to users through the switch. However, with the increasing density of cities, some of the original civil construction switch has been restricted by land and urban planning, so a more advanced and practical outdoor intelligent switch (outdoor ring network cabinet) has emerged. This switch does not require civil construction and occupies a small area. The configuration is very flexible, the power supply method is more reliable, the construction, installation, and commissioning time are greatly shortened, and the overall cost is reduced.
With the development of modern industry, the degree of automation and intelligence of electrical control equipment is getting higher and higher. It has become an inevitable trend and development direction to integrate the monitoring, protection, control and metering of power equipment under normal and accident conditions by using modern electronic technology, sensor technology, communication technology and computer network technology to achieve good management.
Intelligent switchgear (Outdoor Ring Main Unit) adopts and draws on advanced foreign technology, and installs and debugs 12/24kV switchgear, circuit breakers, load switches, current and voltage transformers, 12/24kV power PT, switchgear FTU, RTU, communication control terminal (CCU), 12/24kV metering and automatic meter reading, USP power supply and indicating instruments into a movable, sealed and moisture-proof stainless steel box, thus realizing the integration of primary and secondary systems in urban distribution networks and modular assembly, shortening the construction period and greatly improving the reliability of urban power grid operation.
