The gas-insulated environmentally friendly cabinet independently developed and produced by Qingchang Electric Power is a ring network cabinet that uses a mixed gas mainly composed of nitrogen as the insulating medium. This type ofenvironmentally friendly mixed gas replaces SF6 as the insulating medium, which can solve the problem of SF6 gas leakage pollution.
It has a high level of operational safety and serves as a core unit in the distribution network, applied within the distribution network. The device mainly consists of modular components such as a sealed switch gas chamber, cable room base, mechanism room, and instrument room.The switch gas chamber contains core components such as a sealed circuit breaker switch body, load switch body, three-position isolation grounding switch body, and environmentally friendly insulating sleeve, achieving a fully sealed, maintenance-free structure. The cabinet uses inert gases like nitrogen for insulation, making it more environmentally friendly; the use of environmentally friendly solutions aligns better with the development direction of China's power industry, making the QEFG type environmentally friendly gas cabinet one of the most popular types of ring network cabinets in China today. Compared to solid cabinets, gas-insulated environmentally friendly cabinets are lighter, making them easier to transport and install. The excellent intelligent design fully meets the current demand for smart grids in China, enhances electrical safety, significantly increases daily work efficiency, and reduces the burden of manual management.
