The invention provides a train traction high-voltage box, a power supply method and a data interaction system, and belongs to the technical field of rail transit, and the train traction high-voltage box comprises a high-voltage isolation switch HVIS which is used for supplying power to at least one converter control device in different working modes; the high-speed circuit breaker HSCB is connected with the HVIS and at least one alternating current control device; and a programmable logic controller (PLC) for controlling the HSCB to control power supply and power failure to the at least one AC control device. The PLC is arranged in the train traction high-voltage box, hard wire connection between the alternating current control equipment and electronic components of the train traction high-voltage box is avoided, the number of devices in the train traction high-voltage box and the number of devices in the alternating current control equipment are reduced, and improvement of fault tolerance of the train traction high-voltage box is facilitated. The electronic components of the train traction high-voltage box are uniformly controlled through the PLC, and the integration degree of control over the electronic components of the train traction high-voltage box is improved.
本发明提供一种列车牵引高压箱、供电方法及数据交互系统,属于轨道交通技术领域,列车牵引高压箱包括:高压隔离开关HVIS,用于向至少一个变流控制设备进行不同工作模式的供电;高速断路器HSCB连接HVIS和至少一个交流控制设备;可编程逻辑控制器PLC,用于控制HSCB,以控制向至少一个交流控制设备供电和断电。本发明通过在列车牵引高压箱中设置PLC,避免了交流控制设备与列车牵引高压箱的电子元器件的硬线连接,减少了列车牵引高压箱中器件的数量和交流控制设备中器件的数量,有利于提高列车牵引高压箱的容错性。通过PLC对列车牵引高压箱的电子元器件进行统一控制,提高了对列车牵引高压箱的电子元器件控制的集成度。
