XGW15-12/24 Outdoor Intelligent Opening and Closing Station

(Outdoor Ring Network Cabinet)

With the continuous development and progress of society, China's urban power grid has undergone tremendous changes, and most cities have formed or are forming numerous areas with dense electricity loads. In the past, the power supply from substation 12/24kV lines (or branch lines) to direct users has been difficult to meet the needs of urban development. As a result, a new way of supplying power is generated to supply power to the user through opening and closing. However, with the intensification of urban intensification, some of the original civil opening and closing stations have received restrictions on land and urban planning, so a more advanced and practical outdoor intelligent opening and closing listening (outdoor ring network cabinet) has emerged. This opening and closing does not require civil construction, and the floor space is small, the configuration is very flexible, the power supply mode is more reliable, the construction and installation and commissioning time are greatly shortened, and the overall cost is reduced.

This opening and closing does not require civil construction, and the floor space is small, the configuration is very flexible, the power supply mode is more reliable, the construction and 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, the use of modern electronic technology, sensor technology, communication technology, computer network technology, the power equipment under normal and accident conditions monitoring, protection, control, calculation, etc. integrated, to achieve good management, has become an inevitable trend and development direction.

Intelligent opening and closing station (outdoor ring network cabinet) is to adopt and learn from foreign advanced technology, the 12/24kV switchgear, circuit breaker, load switch, current and voltage transformer 12/24kV power supply PT, opening and closing office FTU, RTU, communication control terminal (CCU), 12/24kV metering and automatic meter reading, USP power supply and indicator instrument installation and debugging into a movable, sealed, moisture-proof stainless steel box, so as to realize the integration of the primary and secondary systems in the urban distribution network. The modularization of the assembly shortens the construction period and greatly improves the reliability of the operation of the urban distribution network. Compliance with standards
