额定电压 72.5 kV 及以上电力变压器和气体绝缘金属封闭开关设备之间的直接连接

[中文适用范围]： 适用于满足IEC 60517要求的额定电压72.5 kV及以上气体绝缘金属封闭开关设备与满足IEC 60076要求的电力变压器之间的单相连接组件，并配有满足要求的全浸式套管IEC 60137，其一端浸入变压器油中，另一端浸入开关柜的绝缘气体中。其目的是在这些连接组件的接口布置中建立电气和机械互换性，并确定供应限制。 [外文原描述]： Applicable to the single-phase connection assemblies between gas-insulated metal-enclosed switchgear for rated voltages of 72,5 kV and above satisfying the requirements of IEC 60517 and power transformers satisfying the requirements of IEC 60076 and fitted with completely immersed bushings satisfying the requirements of IEC 60137, one end of which is immersed in the transformer oil, and the other end in the insulating gas of the switchgear. Its purpose is to establish electrical and mechanical interchangeability in the interface arrangement of these connection assemblies and to determine the limits of supply.
