标准摘要
[中文适用范围]: “IEC 62271 的这一部分适用于刚性高压气体绝缘输电线路 (GIL),其中绝缘@至少部分@通过大气压下的空气@以外的非腐蚀性绝缘气体@获得额定电压的交流电高于 52 kV@ 且服务频率高达并包括 60 Hz。当 IEC 62271-203 的规定不涵盖 GIL 的应用时,应使用本国际标准(见注 3)。高压气体绝缘输电线路@特定元件可用于高压气体绝缘输电线路与套管@电力变压器或电抗器@电缆箱@金属封闭避雷器@电压互感器或GIS@覆盖等其他设备之间的连接注1:在本国际标准中,术语“高压气体绝缘输电线路”缩写为“”吉尔“”。注 2:在本国际标准中,“气体”一词是指制造商定义的气体或气体混合物。注 3:给出了 GIL 应用的例子: ?C 全部或部分高压气体绝缘输电线路直接埋地;或 ?C 高压气体绝缘输电线路全部或部分位于公众可到达的区域;或 ?C,其中高压气体绝缘输电线路较长且典型气室长度超过 GIS 技术的常见做法。” [外文原描述]: IEC 62271-204:2011 applies to rigid HV gas insulated transmission lines (GIL) in which the insulation is obtained, at least partly, by a non-corrosive insulating gas, other than air at atmospheric pressure, for alternating current of rated voltages above 52 kV, and for service frequencies up to and including 60 Hz. This standard cancels and replaces IEC/TS 61640:1998. It is a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - update to be in line with IEC 62271-1:2007 and 62271-203 and alignment of the voltage ratings and the test voltages; - addition of new information for gas tightness and corrosion protection. This publication is to be read in conjunction with IEC 62271-1:2007.
