阻抗匹配平衡变压器的模型试验及其性能分析

THE MODEL TEST AND ITS PERFORMANCE ANALYSIS OF THE IMPEDANCE-MATCHING BALANCE TRANSFORMER

本文针对牵引负荷的负序电流对电力系统的不良影响,提出采用阻抗匹配平衡变压器作电气铁道的牵引变压器,并用研制的专用模型作了试验,用试验数据进行了性能分析,证明该新型平衡变压器对抑制负序影响的有效性。

Considering the harmful influence of the negative current of electric traction loads on the electric power system, we suggest that the impedance-matching balance transformer be used as the traction transformer of electric railway, After finishing the test on the specialpurpose model and analysing the results, we can prove the new type balance transformer quite effective in cutting down the negative influence.
