Brief Analysis of 220 kV GIS Distribution Equipment Design and Application
It has taken 55 years for national 220kV high voltage distribution equipment of AIS to evolve to widely used GIS now. Compared to the traditional equipment,GIS distribution equipment is less land occupation,quick to install,easy maintenance,long repair cycle,better contamination resistance,better earthquake resistance and high reliability,especially suitable to apply in industrial pollution area,large or medium sized cities and other power distribution projects sensitive to landscape covers,it has been widely applied in 220 kV power distribution project in recent years. In this article,through two example 220kV projects which have been put into operation,the use of GIS distribution equipment is introduced and illustrated.
