摘要
针对高速动车组例行试验用三相变单相牵引供电变压器原边三相电流不平衡问题,从补偿原理、补偿手段及补偿效果3个方面进行了深入分析,并提出了动态补偿的解决方案。
In view of the unbalance of the primary 3-phase current in the traction power supply transformer while changing the 3-phase into single phase in the routine test on high speed multiple units,further analysis is made from the three aspects of compensation principle,compensation measure and compensation effect.The solution scheme of dynamic compensation is put forward.
