分析了地磁暴产生的原因,探究了GIC在高铁AT供电方式下侵入动车组车辆牵引变压器的机理,以CRH2型动车组为例,利用Maxwell软件仿真,分析了不同数值的GIC对高铁车辆变压器油箱的电磁系统和损耗造成的影响。
The reasons of geomagnetic storm are analyzed. The mechanism of GIC intruding into the traction transformer of the EMU vehicle in the high-speed AT power supply mode is discussed. Taking the CRH2 EMU as an example, Maxwell software simulation is used to analyze the effect of GIC with different values on the transformer tank The effects of electromagnetic system and loss.
