气体绝缘输电线路技术及其应用

气体绝缘输电线路(GIL)是类似GIS(气体绝缘金属封闭组合电器)封闭母线的气体绝缘大容量输电设备,其电气特性与架空线路相似且具有占地空间小等优点。介绍GIL的制造厂家、国际标准、基本结构和安装方式,分析GIL具有的输送容量大、损耗小、对环境影响小、可靠性和安全性高等技术优势,并介绍GIL在国内外的典型应用实例,为其在国内的更广泛应用提供参考。

Technology and application of gas-insulated transmission lines

A gas-insulated transmission line(GIL) is the large capacity transmission equipment with gas insulation as a GIS enclosed bus.Its electrical specification is like an overhead line and it has many advantages such as saving space,etc.The manufacturers,international standards,basic structures and installation types,and etc.for the gas-insulated transmission line(GIL)were briefly introduced.The advantages of GIL technology,such as large transmission capability,low power losses,little environment effects,high reliability and safety,were analyzed.The typical applications of GILs both in domestic and international were introduced.
