Product Overview
With the continuous development and progress of society, China's urban power grid has undergone great changes, most cities have formed or are forming from more dense areas of electrical loads. In the past, the kind of 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 way of supplying power to the users through the open and close the power supply. However, with the intensification of urban densification, some of the original civil construction type closure has been subject to land and urban planning constraints, so there is a more advanced, practical outdoor intelligent closure (outdoor ring network cabinet). This open and close without civil construction and covers an area of less, the configuration is very flexible power supply more reliable, construction and installation, commissioning time is greatly reduced, the overall cost reduction.
Intelligent opening and closing house (outdoor ring network cabinet) is to adopt and learn from foreign advanced technology, will be 12/24kV switchgear, circuit breaker, load switch. Current and voltage backbone, 12kV power supply PT, open and close FTU, RTU, communication control terminal (CCU), 12/24kV metering and automatic meter reading, USP power supply and indicating instrumentation, etc. are installed and debugged into a movable, sealed and moisture-proof stainless steel box, thus realizing the integration and modularization of the primary and secondary systems of the urban power distribution network, shortening the construction cycle, and greatly improving the operation of the urban power grid. It shortens the construction period and greatly improves the reliability of urban power grid operation.

Environmentally friendly gas-insulated metal enclosed switchgear is the most commonly used three-phase intelligent gas-insulated AC cabinet and is widely used in various switchgear sets, with population concentration in the country, the power market must be supported, environmentally friendly gas-insulated switchgear will also grow with market development; market potential is yet to be tapped. At the same time, as the product integrates data collection and management, data processing and storage, online monitoring of switchgear, advanced analysis, and other multifunctions in one, network intelligent monitoring and management of the distribution network, so that the distribution network operates in a safe, reliable, high-quality, and efficient best state, to achieve remote monitoring, management, and control of the power system distribution network, to achieve network optimization, safe electricity use, power management, energy saving, and consumption reduction; at the same time, the system can be widely used in intelligent power distribution fields such as transportation, factories, hospitals, schools, buildings, residential areas, and commercial office buildings.
