With the development of modern industry, the requirements for automation and intelligence of electrical control equipment are getting higher and higher, using modern electronic technology, sensor technology, communication technology, computer network technology, it has become an inevitable trend and development direction to integrate the monitoring, protection, control, measurement and other modules of power equipment under normal and accident conditions to achieve a good unified management purpose. In recent years, China's urban power grid has undergone earth-shaking changes, most cities have formed or are forming a large number of power load-intensive areas, the new power supply mode is through the ring cage/opening and closing, so it does not need civil engineering, small footprint, flexible configuration, reliable power supply mode, short construction, installation and commissioning time and low overall cost, it has been greatly developed. MGW-12-type outdoor high-voltage ring cage is based on the summary of the safe and reliable operation of the branch box with Switch experience and combined with the distribution network automation system technology and the development of suitable for China's national conditions, on behalf of the domestic advanced technology level of complete sets of electrical products. MGW-12 outdoor high-voltage ring net cage will install 12kV switch cabinet, power supply PT cabinet, feeder FTU, RTU, communication control terminal, metering and automatic meter reading, UPS power supply, etc. into a movable, sealed, in the moisture-proof stainless steel or non-metallic box, the construction period is shortened, thus realizing the integration and modularization of the primary and secondary systems of the urban distribution network.
