mica insulating pipe

Study on multi-stress aging of epoxy/mica insulation based on fingerprint parameters;

基于指纹参量的环氧云母绝缘多因子老化的实验研究

During the process of multifactor aging of epoxy/mica insulation, the AC current parameters have apparent developing laws with insulation aging time.

在环氧云母绝缘线棒多因子老化过程中 ,交流电流参量随老化时间呈现一定的变化规律 ,而且第二电流激增电压与剩余击穿电压有较强的相关性 ,可以作为特征参量来评定环氧云母绝缘的老化程度。

Accelerated aging test to the epoxy/mica insulation of stator bars in generator is presented in this paper.

对环氧云母绝缘电机线棒进行了老化试验 ,在不同的老化阶段 ,测试了线棒的介质损耗角正切、电容、电流急增点等非破坏性参数和破坏性参数——剩余击穿电压。
