Product overview:
With the continuous development of the society, great changes have taken place in Chinese urban power grid. Most cities have formed or are forming many intensity areas of electricity load. In the past, the power supply from the 12/24kV line (or branch line) of the substation to the direct customers has been difficult to meet the requirements of urban development. Thus, a new way of supplying electricity to the user was developed by opening and closing the station. But with the intensification of the city, some of the original civil type open and close has been restricted by land and urban planning, so a more advanced and practical XGW-12 box type open and close (outdoor ring network cabinet). This opening and closing place does not need civil construction and occupies a small area, the configuration is very exible power supply mode is more reliable, the construction, installation, debugging time is greatly shortened, the overall cost is reduced.
With the development of modern industry, the degree of automation and intelligence of electrical control equipment is higher and higher. Using modern electronic technology, sensor technology, communication technology and computer network technology,it has become an inevitable trend and development direction to integrate the monitoring, protection, control and measurement of power equipment under normal and accident conditions to achieve good management.
XGW-12 box type switchgear (outdoor ring network cabinet) 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 indicator instruments are installed and adjusted into a movable, sealed and moisture-proof stainless steel box, so as to realize the integration of the primary and secondary systems of the urban distribution network, modular assembly and shorten the construction cycle. Greatly improve the reliability of urban power grid operation.
