变压器隔直装置应用及问题分析

Application and Analysis of Transformer DC Blocking Device

越来越多的直流输电线路投入运行,电网呈现交直流共存的现象。但直流输电在双极不平衡及单段运行的方式下,对临近的交流变压器造成较大的影响。详细介绍了宾金直流系统对我厂主变造成的影响,以及安装隔直装置后达到的效果。

More and more DC transmission lines are put into operation,and the power grid is coexisting with AC and DC.However,under the mode of bipolar unbalance and single-segment operation of DC transmission,it has a greater impact on the nearby AC transformer.The impact of Binjin DC system on the main transformer of our factory and the effect achieved by installing DC blocking device are introduced in detail.
