1 问题的提出 随着对机车监控要求的提高,铁道部对所有ＤＦ4Ｂ型机车要求改装ＬＫＪ 93型监控装置,在改装时明确要求:在机车控制电路中相关电磁接触器线圈和继电器线圈上并联过电压吸收片,以减少线圈失电时释放的过压干扰监控装置正常工作。由此,我们在改装ＬＫＪ 93监控装
1 raised the issue With the improvement of locomotive monitoring requirements, the Ministry of Railways for all DF4B locomotives require modification LKJ 93-type monitoring device, the conversion requirements explicitly: the locomotive control circuit in the solenoid coil and the relay coil connected in parallel Voltage absorption sheet, in order to reduce the power failure when the coil over-voltage interference monitoring device is working. As a result, we are refitting LKJ 93 monitoring equipment
