多功能平衡牵引变压器谐波抑制效果研究

The Research on the Effect to Leach the Harmonics of the Multi function Balance Traction Transformer

在已有的谐波理论分析及计算的基础上 ,针对多功能平衡牵引变压器 SGPH-2 6/2已设计出的滤波参数 ,在不同的运行工况下 ,分别测量了滤波器投入和不投入两种情况下 ,原方三相电压和电流的波形及畸变率 .实验表明 。

Based on the theoretical analyses and calculations of the harmonics,the parameters of leaching harmonics are designed for the Multi Function Balance Traction Transformer(MFBTT).Under the different status of work,the primary waves of the voltages and currents of the three phases and the percentages of the distortion of the sine wave are measured respectively when filters are connected or not connected with the main circuit.The results of tests indicate that it is obviously effective to leach harmonics after filters have been connected with the circuit.
