核电厂气体绝缘金属封闭线路布置方式的应用研究

The Layout of GIL in Nuclear Power Plant

气体绝缘金属封闭输电线路(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,因其优秀的电气性能及可靠性高、输送容量大、占地小等优点,在核电工程中得到了大量的应用。通过介绍GIL的主要技术特点,及GIL在我国核电厂中的应用情况,阐述了核电厂中GIL布置及敷设方式的选择原则和注意事项。

GIL（Gas Insulated Metal Enclosed Transmission Line）is a kind of transmission equipment, it is designed to transfer high amount of energy, and the structure of GIL is very similar to the busbar of GIS（Gas Insulated Metal Enclosed System）. There are plenty of applications in NPP（nuclear power plant） for its excellent electrical performance and other characters, such as safety, great power carrying capability, low sizes. This paper introduces the characteristic of GIL, and the applications in Chinese NPP, describes the principal and notices for the arrangement and layout of GIL.
