中压式气体绝缘金属封闭开关柜(C-GIS)是一种小型化、智能化的GIS设备,是将GIS的SF_6绝缘技术、密封技术与空气绝缘金属封闭开关设备制造技术进行有机结合的产物,具有绝缘介质压力低、可扩展、全屏蔽电缆终端进出线、不受环境影响等特点。从大型矿井供电系统的特点出发,介绍了C-GIS装置应用于矿井供电系统的优势及存在的问题,提出了相应的解决方法,并对C-GIS在矿井供电系统的应用做出了展望。
Medium Voltage Gas-Insulated Metal-enclosed Switchgear (C-GIS) is a miniaturized and intelligent GIS equipment that combines the GIS SF6 insulation technology, sealing technology and air-insulated metal-enclosed switchgear manufacturing technology. , With low dielectric medium pressure, scalable, fully shielded cable terminal access, not subject to environmental impact and so on. Based on the characteristics of large-scale mine power supply system, the advantages and problems of C-GIS applied to mine power supply system are introduced. Corresponding solutions are put forward and the prospect of C-GIS application in mine power supply system is also presented.
