摘要
针对交流传动电力机车的传动特点 ,对其中的牵引变压器的工作状态进行了分析 ,指出交流传动电力机车用牵引变压器设计时需考虑的牵引绕组的短路阻抗大、电流的高次谐波、网压波动大可能引起的过励磁以及直流磁化等问题 。
In accordance with the driving characteristics of AC driving locomotive, the working status of its traction transformer is analysed. The questions that should be considered in the traction transformer design of AC driving locomotive are mentioned. These questions are the large short-circuit impedance of traction winding, higher harmonic current, over-excitation and DC magnetization caused by large variation of the network voltage, etc. Some disposal methods are given.
