摘要
本文中笔者对两台110kV变压器空载损耗异常的原因进行了分析,研究了硅钢片剪切毛刺导致的铁心级间电阻下降对变压器空载损耗的影响,提出了一些预防硅钢片毛刺引起空载损耗增加的措施。
The reasons of abnormal no-load loss were studied for two 110kV power transformers,and the decrease of core interlaminar resistance is analyzed.According to study,the core interlaminar loss will increase the no-load loss,and some advices were provided.
