浅谈GIS设备后期扩建

Discussion on Later Expansion of GIS

气体绝缘金属封闭开关设备(GIS)因其占地面积小、与环境的协调性好、配置灵活、受外部条件影响小等优点受到电力用户的青睐,成为了电网的关键设备。随着GIS设备在电网中的大量应用,GIS设备后期扩建对正在运行的前期设备的影响就很值得关注。笔者通过对GIS常见扩建方式以及扩建时开关操作的分析,阐述了GIS设备后期扩建的方法,得出了GIS设备后期扩建如何减少现场对接工作的时间和拆解GIS设备本体的范围、如何能尽量减小因扩建过程而造成的设备停运或尽可能地减少停电时间的途径。

GIS is a key equipment in power grid. Therefore, the influence of later expansion of GIS equipment on the existing running GIS equipment should be paid attention to. In this paper, the common expansion methods of GIS equipment and the switching operation in expanding process are analyzed, and the later expansion methods of GIS equipment are described. Subsequently, such approaches are proposed as reducing the time of connecting operation on site and the scope of dismantling main GIS equipment in later expansion, and shortening the outage time of the equipment and power supply in the process as much as possible.
