GB/T 7674-2008
AbolishedGas-insulated metal-enclosed switchgear for rated voltages of 72.5kV and above
额定电压72.5kV及以上气体绝缘金属封闭开关设备
Application Summary AI generated
This standard specifies technical requirements, test methods, and acceptance criteria for gas-insulated metal-enclosed switchgear (GIS) designed for rated voltages of 72.5 kV and above. It is applied in high-voltage electrical power systems, including substations and power plants, to ensure the safe, reliable, and compact operation of switchgear assemblies that use sulfur hexafluoride (SF₆) or other insulating gases. The standard is used by manufacturers, utilities, and testing laboratories for design verification, type testing, and routine inspection of GIS equipment.
