摘要
基于动车组车体实际结构,构建了高速动车组升弓过程的电路分析模型,解析了过电压在各车体上的传播及折反射特性,在现场开展了试验测试,理论结果与实测结果波形基本一致,过电压幅度存在一定的差异,对差异产生的原因进行了分析。
Based on structure of high-speed EMUs body,equivalent electric circuit model was established to analyze the transmitting and reflecting characteristics between different car bodies,as well as experiments were carried out in field.It was demonstrated that wave figure of theoretic result was consistent with experimental result but difference for over-voltage amplitude,reasons of which were analyzed.
