摘　　要：通过一起干式铁心串联电抗器绝缘垫块异常老化的分析,发现了绝缘垫块堵塞绕组散热气道时受影响面积虽不大,但会引起绕组温升偏高,造成绝缘垫块异常老化。Based on analysis of the abnormal aging of insulation pad in a dry type iron core series reactor,it is discovered that even the affected area of the coil is small when the insulation pad is blocked in the coil cooling air passage,however it will cause the coil temperature rising. This finally causes abnormal aging of the insulation pad.

关 键 词：干式铁心串联电抗器 绝缘垫块 温升 老化
