摘要
本文利用102G—D型气相色谱仪研究了油纸复合介质在模拟放电故障作用下的产气组份特点,提出了与油——纸交界面沿面放电故障相对应的新的特征气体比值编码,丰富和发展了IEC三比值判别法中的编码组合,为诊断电力变压器围屏爬电故障提供了参考依据。
This paper studies the composition characteristics of the gases under analogue discharge faults in oil-paper insulating materials using 102G-D type chromatograph. New IEC ratio codes reflecting oil-pressboard interface discharge is presented, which can be used as a reference criterion to diagnose pressboard barrier fault in power transformer. IEC ratio codes have been developed and enriched on the basis of experiments.
