摘要
采用工频电压法和阻尼振荡波电压法研究热缩式电缆附件在4种缺陷情况下的局部放电特性,对比分析两种电压情况下的局部放电起始电压和局放模式。结果表明:两种方法在局部放电特性研究中具有一致性,各种缺陷的局部放电统计特征具有较为明显的差异。
The partial discharge characteristics of four defects in heat-shrinkable cable accessories, wnlcn were termination without stress tube, incorrect use of insulation tape as semi-conductive adhesive tape in the middle joint, void and metal particles on the surface of XLPE insulation, were studied by AC voltage method and damped oscillating wave voltage method. The partial discharge inception voltage and pat- terns under damped oscillating wave voltage and AC voltage were compared. The results show that the two methods are consistent in the study of partial discharge characteristics, and there are obvious differ- ences in the partial discharge statistical characteristics of various defects.
