With the continuous development and progress of society, great changes have taken place in China's urban power grid. Most cities have formed or are forming a large number of electricity 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 construction closures have been restricted by land and urban planning. Therefore, a more advanced and practical outdoor high-pressure ring cage (standardized) has emerged. The product does not need civil construction and occupies a small area, the configuration is very flexible, and the power supply is more reliable; The time of construction, installation and commissioning is 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. The use of modern electronic technology, sensor technology, communication technology, computer network technology, the power equipment under normal and accident conditions of monitoring, protection, control, measurement and other integration. To achieve good management in this way has become an inevitable trend and development direction.
Outdoor high pressure ring cage (standardized) is the use of foreign advanced technology. It will be 12/24kV switchgear, circuit breaker, load switch, current and voltage transformer, 12/24kv power supply PT, FTU,RTU, communication control terminal (CCu), 12/24kV metering and automatic meter reading, USP power supply and indicating instruments installed and adjusted into a movable, sealed moisture-proof stainless steel box. Thus, the integration of the primary and secondary systems of the urban distribution network and the modularization of the assembly are realized, the construction period is shortened, and the reliability of the operation of the urban power network is greatly improved.
