在SS4改型电力机车检修过程中,处理与XDC-II型甩单节有关的故障时,常常因不了解甩单节装置的原理、装置与机车固有控制电路的逻辑关系不明确等原因,影响正常的生产进度。为此,迫切需要将甩单节装置原理电路与机车固有控制电路结合在一起,绘制与甩单节有关的机车控制电路图,新电路图能直观反映甩单节装置在机车控制相关环节中所起的作用,作为机车故障处理的参考依据。
In SS4 modified electric locomotive maintenance process, dealing with the XDC-II rejection of single-section-related failure, often because of the rejection of single-unit device principle, the device and the locomotive’s inherent logic control circuit is not clear and other reasons, the impact Normal production schedule. For this reason, it is urgent to combine the principle circuit of rejection of single-unit device with the inherent control circuit of locomotive to draw the locomotive control circuit diagram related to rejection of single block. The new circuit diagram can intuitively reflect the single- Role, as a locomotive troubleshooting reference.
