额定电压 72.5 kV 及以上刚性高压气体绝缘输电线路

[中文适用范围]： 适用于额定电压为 72.5 kV 及以上的交流电的刚性高压气体绝缘输电线路 (GIL)，其中绝缘至少部分通过非腐蚀性绝缘气体（大气压下的空气除外）获得，并且服务频率高达 60 Hz（含）。本技术报告旨在用于 IEC 60517 规定不充分的情况。 [外文原描述]： 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 of 72,5 kV and above, and for service frequencies up to and including 60 Hz. It is intended this technical report be used in situations where the provisions of IEC 60517 are not adequate.
