| 摘 要： | 介绍在阻抗匹配平衡变压器基础上发展起来的一种新型多功能平衡变压器的原理及其三相谐波电流计算的实现,分析多功能平衡变压器在10.5kV分接处设置滤波支路后两臂带不同负荷时的滤波效果,并与无滤波装置和27.5kV低压侧滤波的方案进行比较。计算结果表明,多功能平衡变压器在抑制谐波方面具有优越性,值得在铁路上推广。

| Abstract: | It is presented the principle of the new multi-functional balance transformer developed at the basis of the balance transformerwith impedance matching as well as the realization of calculation of 3-phase harmonic current. The filter effects are analyzed for thetransformer with different loads in two arms after a filter branch is tapped in windings of 10.5 kV, and are compared with the scheme withouta filter device and with a filter in 27.5 kV low-voltage side. The calculation results indicate that the multi-functional transformer featuresexcellence in harmonic suppression and is worth of wide applications in railway industry. |
