摘要
多功能平衡变压器既具有三相变两相的功能 ,也具有三相变三相的功能。二次侧的两相带牵引负荷 ,而二次侧的三相可带地区负荷 ,兼作无功补偿和高次谐波滤波。本文导出了三相变两相和三相变三相的等值电路 。
The Multi Function Balancing Transformer(MFBT) can transfer voltages from three phase to two phase,as well as from three phase to three phase.The secondary two phase system supplies electricity to traction locomotives.Meanwhile,the secondary three phase system can be used in many such purposes as providing local electricity,compensation of reactive power and reducing the amount of harmonics.This paper describes the derivation of the equivalent circuits for three phase to two phase and three phase to three phase.The derivative circuits have very important significance for calculation of operating and short circuit impedance.
