220kV变电站主变铁心故障的分析
摘要
就主变抽真空过程中测试铁心绝缘发现的问题
指出在抽真空过程中测出的绝缘数值不能真实反映设备绝缘状况。
Abstract
In view of the problem founded while testing the insulation of iron core in the course of vacuumizing the main transformer in a 220 kV substation
it is proposed that the insulation resistance value can not reflect the real insulating situation during vacuumizing.
