摘要
对气体绝缘组合式开关设备(GIS)在自然环境适应能力、设备使用的安全性、经济效益等方面的优势和不足进行了分析,论述了GIS设备的制造、运输、现场安装、运行、维护和扩建等应用问题。与传统的空气绝缘开关设备(AIS)相比,GIS设备具有抗震能力强、占地面积小、安装工序少、故障概率低、检修周期长、便于扩建以及经济效益高等特点,SF6气体绝缘保障了该设备使用的安全性和可靠性,模块化运输再拼接提高了该设备安装的灵活性,因此GIS设备可谓是核电厂一次设备的首选。
In this paper, the advantage and disadvantage of gas insulated switchgear （GIS） in environmental adaptability, operation safety and economic benefit are analyzed. Issues concerning the manufacture, transportation, on-site installation, operation, maintenance and extension of GIS equipment are discussed. Comparing those charactenstics with air insulated switchgear （AIS）, GIS is characterized by better aseismic ability, less occupied area and installation process, lower fault rate, longer maintenance period, easier for extension and higher economic benefit, SF6 gas insures the operation safety and reliability of GIS equipment, modular transport and re-assembling improves the installation flexibility. Therefore, GIS equipment may be the first choice for the primary equipment of nuclear power plant.
