摘要
为了全面了解局部放电脉冲在电机定子绕组及检测传感器中的传播特性,在应用部分单元等效电路(partia le lem en t equ iva len t c ircu it,PEEC)模型分析定子槽耦合器(stator slot coup ler,SSC)与绕组线棒耦合通道特性的基础上,对一台模拟实验电机的定子绕组进行了系统的实验研究。得到了单个线圈及其端部的传播通道频率特性、一相绕组传播通道频率特性和相间耦合的频率特性,并在一相绕组的不同位置放入SSC,时域下分析了各个传感器对脉冲信号的耦合结果。所得到的规律可为分析电机定子绕组局部放电特征及其检测提供有效的指导。
The propagation characteristics of partial discharge pulses in generator stator windings and sensors were analyzed based on the coupling characteristics between the stator,slot coupler （SSC） and the winding bar using the partial element equivalent circuit （PEEC） method. The frequency characteristics of a single coil-end, a single coil, a phase winding, and the coupling effects between two windings were analyzed in a series of experimental test＇s. The different temporal pulse coupling effects of the SSC placed at different bars in the phase winding were also investigated. The experimental results can guide the analysis of the partial discharge characteristics in stator windings.
