摘要
长沙市轨道交通2号线列车在设计初期为考虑牵引传动控制的可靠性风险,在牵引系统主电路中设置了压敏电阻和续流回路,但在实际运用中发现,其效果并不明显。现通过试验,并对比国外主要牵引系统供应商的设计,对牵引系统主电路中设置压敏电阻及续流回路的必要性进行了验证。
Considering the reliability risk of the traction system in the initial design of metro vehicle for Changsha Metro line 2, voltage dependent resistor and continuous current circuit are installed in the traction main circuit, but the effect is not obvious in actually operation. Through ex- periment and compared to the vehicle design of internation- al suppliers, the necessity verification for the installation of voltage dependent resistor and continuous current circuit in the traction main circuit is believed to be important.
