大连快速轨道交通3号线车辆电阻制动故障解决

Solution for Faults of Vehicle Resistance Braking in Dalian Rapid Rail Transit Line 3

大连快速轨道交通3号线车辆在高速运行状态下(列车速度大于90km/h以上),执行制动力较高的制动级位(B6或B7级位)操作时,电阻制动中途停止工作,对此故障进行了分析、试验并加以解决。

For the vehicles running on Dalian Rapid Rail Transit Line 3 under high-speed conditions (train speed is more than 90 km/h), their resistance braking will stop working when the higher braking level operation (Level B6 or B7) is executed. In this paper, this fault is analyzed, tested and then settled.
