XGW-12~24kV ring cage (opening and closing) is a new generation modular, multi-functional combination, high reliability, compact and maintenance-free ring network switchgear. It is suitable for ring network power supply of 10~35kV power supply line or Double-radiation power supply can also be used for terminal power supply, which can control and protect electric energy in the area to be powered. It is widely used in urban ring network power distribution with large power supply load density, cable feeder network, large factories and residential quarters. The XGW-12~24kV ring cage (opening and closing) is mainly composed of SF6 gas insulated closed compact switchgear (C-GIS) and metal (or non-metal) outer casing. All high voltage electrified parts are enclosed in SF6 gas insulated. The stainless steel box body can be freely combined according to the user's needs according to the incoming line unit, the outlet unit, the metering unit, the contact unit, the PT (power supply unit), and can be loaded with the distribution automation system. The installation is simple, the ventilation is good, the appearance is environmentally friendly, and there is no Condensation problems, not affected by the environment. In the ring network cabinet, only the distribution automation terminal equipment (FTU/RTU) and communication device can be equipped to communicate with the control center of the distribution automation system, and various voltages such as voltage and current of the line can be measured. Monitor the working status of each switch.
