抽水蓄能电站变压器直流电阻超差故障分析及解决办法

Analysis and Solving Method for the Transformer DC Resistance of Pumed Storaged Power Station

某抽水蓄能电站2号主变压器低压侧直流线电阻超差,本文通过对其10年的数据进行分析比较,以及最近一次大修前后的数据比较,结合其他试验数据,提出原因分析及解决建议。

A power station No.2 main transformer low voltage station DC line resistance is overproof, through the analysis and comparison its ten years of data, as well as the last major overhaul before and after the comparison of the data, and the last major overhaul data,combined with other test data, put forward the reason for the analysis and settlement.
