摘要:

摘要:为了满足带电检测研究、培训的需要,新疆电力公司研制了一套带电检测缺陷模拟装置。装置中设置了沿面放电缺陷等多种运行中经常出现的缺陷模型,通过有限元方法计算沿面放电缺陷在运行条件下的电场分布情况,探讨了缺陷配置参数对电场分布情况的影响,并建立了沿面放电缺陷小模型。研究发现,电压升至5kV时,利用DMS超高频局放测量仪开始捕捉到模型内部的局部放电信号,电压升至9kV时,试验模型起晕,出现明显的局部放电典型图谱,连续电压升至27kV时连续击穿,确定了缺陷参数的大致范围。局部放电带电检测模拟装置用于研究和教学培训,取得了良好的效果。

Abstract:

Abstract:For live detection and training, State Grid Xinjiang Power Company developed a set of live faultiness simulation device. This device featured with fault discharge along surface and many other common fault model. Based on the electric field distribution while fault discharge along surface, this paper discussed the effect of fault parameter on the electric distribution. Fault discharge along surface minimodel was established. Based on research, if voltage boosted to 5kV, DMS ultrahigh frequency partial discharge meter will capture the partial discharge signal; if voltage boosted to 9kV, test model generated corona and typical partial discharge pattern; there will be continuous breakdown if voltage boosted to 27kV. Approximate range of fault parameter was determined. Partial discharge live detection simulating device well performed in research and training.
