摘要
本文在电力行业标准“三比值”法诊断变压器类设备故障的基础上,尝试增加运用国际大电网会议(CIGRE)工作组报告介绍的“MSS”编码判断方法,综合分析了国内已经证实发生涉及纸绝缘放电故障的击穿跳闸前油气相色谱数据,探讨可否提前诊断此类放电故障的可能性。
Based on the power industry standard"three-ratio"method for fault diagnosis of transformer equipment,this paper attempts to use the"MSS"method proposed in the report of the joint working group of CIGRE,comprehensively analyzes the DGA data before breakdown related to paper-insulation discharge faults,which have been confirmed by disintegration in China,and discusses the possibility of early diagnosis for this kind of discharge faults in the field.
