Background
In recent years, gas insulated metal enclosed electric power transmission lines (GILs) have been selected for each large power plant in china in the outgoing line system. GIL is a metal-enclosed rigid structure that is sealed and insulated by a pipe, and is generally not affected by environmental factors such as bad weather and special terrain. Meanwhile, the GIL has no electromagnetic influence on the environment basically, and the influence of the external magnetic field on other equipment and personnel can be ignored. Moreover, the GIL can effectively utilize limited space resources, and realize that high-voltage high-capacity electric energy directly enters the load center of the urban underground substation and the like. Gas insulated fully closed switchgear (GIS) has been widely operated around the world, and GIS is widely used not only in high voltage and ultra high voltage fields but also in ultra high voltage fields.
