550 kV Hybrid Gas Insulated Switchgear and Its Application
摘要
阐述了气体绝缘金属封闭组合电器(HGIS)的概念
介绍了HGIS的技术特点、先进性及工程应用特点
通过与传统敞开式开关设备(AIS)以及气体绝缘金属封闭开关设备(GIS)的综合技术经济性能比较
说明了HGIS的确具有高可靠性和高性价比
是值得在550 kV(330 kV)电站中广泛应用的开关设备。此外
笔者也给出了550 kV HGIS未来的技术发展方向。
Abstract
This paper elaborates hybrid gas insulated switchgear(HGIS) concept
introduces its technical characteristics
advantages and project application characteristics.The comparisons of the comprehensive technical economy performance between HGIS
AIS and GIS have been carried on.It is shown that HGIS indeed has high reliability
high performance-to-price ratio
and is worth widespread applied in 550 kV(330 kV) power station.Moreover
the future technological development direction of 550 kV HGIS is pointed out.
