摘要
本文以典型110kV变电站两台变压器并联运行后出现较大环流为实例进行分析,得出结论:环流由主变绕组变比误差不同引起,正确的配套变压器可以避免并联运行产生的环流,减少附加损耗及其他安全事故,确保变压器安全、稳定的运行,同时也给变电站变压器的配套选型及维修工作提供很好的借鉴意义。
In this paper, after running a typical 110kV substation two transformers in parallel, a larger circulation as an example, the analysis by the main transformer winding circulation becomes different than the error caused by the correct matching transformer avoids parallel circulation generated by the operation, but also reduce the additional losses and other security accidents, ensure that the transformer safe and stable operation, and to support the selection and maintenance of the substation transformer to provide a good reference.
