摘要
为解决当前国家标准对反应堆电气贯穿件局部放电试验在试验方法和判定标准等方面存在的不完善、不明确之处而造成不能完全满足实际需求的问题,本研究在综合考虑了各方面指标要求的基础上制定了一套脉冲电流法检验中压电气贯穿件局部放电性能的试验方案,并开展了验证试验。结果表明:中压电气贯穿件熄灭电压对应的“局放脉冲参量幅值的低值”定为15 pC较为合理,局部放电主要发生在其导体组件多层热缩管之间的气隙中。
In order to solve the problem that the current national standard can not fully meet the actual needs due to the imperfection and indeterminacy of the test method and judgment standard of partial discharge test of the electrical penetration assembly for reactor,on the basis of comprehensive consideration of various index requirements,we set a test scheme for partial discharge characteristics of electrical penetration assembly of medium voltage by pulse current method,and validation tests were carried out.The results show that it is reasonable to set the low value of partial discharge pulse parameter amplitude corresponding to the extinction voltage of the medium voltage electrical penetration as 15 pC,and partial discharge mainly occurs in the air gap between the multi-layer heat shrinkable tubes of its conductor components.
