按照技术规定,东风型内燃机车架修后试运时,全磁场工况电流分配不均匀度不超过8%。我段机车试运中因牵引电动机的问题造成电流分配不均的情况时有发生,仅今年三、四月就连续出现两台:一台是0074号机车,2—3D 电机比1—6D 电机电流大,另一台是0117号机车,4—5D 电机比1—6D 电机电流大,都是 According to the technical regulations, when the Dongfeng internal combustion engine frame is repaired and transported, the current distribution unevenness in the whole magnetic field condition does not exceed 8%. In the trial run of locomotives, the situation of uneven current distribution caused by traction motors has occurred from time to time. There are two consecutive ones in March and April this year: one is 0074 locomotive, 2-3D motor is more than 1-6D motor Current, the other is 0117 locomotive, 4-5D motor current than 1-6D motor are large, are
