摘要
本文研究了运行中干抗的温度分布特性,并通过脉冲过电压试验检测不同老化等效时长的匝间绝缘性能,对老化试验后的干抗进行了解剖分析和匝间工频耐压试验,得到了不同热老化时长下匝间绝缘的状态和性能。
In this paper, the temperature distribution characteristics of dry reactance in operation are studied, and the interturn insulation performance of different aging equivalent time length is tested by pulse overvoltage test. The dry reactance after aging test is dissected and the interturn power frequency voltage withstand test is carried out, and the state and performance of interturn insulation under different thermal aging time are obtained.
