摘要
针对宁波轨道交通1号线一期车辆在实际运用过程中因接触器接触不良而引发的紧急制动情况,分析车辆紧急制动控制电路,对电路电流进行测试,重新对紧急制动接触器进行选型和验证。
According to the emergency braking situation caused by contactor of Ningbo Rail Transit Line 1 Phase 1 vehicles in the application process, this paper analyzes the emergency brake control circuit, and tests the circuit working current. Type selection and verification have been carried out to choose a new kind of emergency brake contactor.
