在现代内燃机车中,其牵引电动机通常都是采用并联的,而且不用采取任何特殊措施即可补偿所有并联支路的电流。按技术规程规定,电动机电流接近连续时,在全磁场上电流分布的不均匀度不超过8％,而在弱磁场上不超过20％。电流分布的恶化会引起发电机端子上的功率降低(按电动机电流的最大值调节),恶化粘着重量的利用以及引起其它不利作用。根据内燃机车的计算和生产经验证明,在新内燃机车上,电流分布的比率完全符合要
In modern diesel locomotives, the traction motors are usually paralleled, and all the parallel branches can be compensated for current without any special measures. According to technical regulations, the motor current is close to continuous, the current distribution in the whole field of non-uniformity does not exceed 8%, while in the weak magnetic field does not exceed 20%. Deterioration of the current distribution can cause a decrease in power at the generator terminals (adjusted to the maximum motor current), deteriorating the utilization of adhesive weight and causing other adverse effects. According to the calculation and production experience of diesel locomotives, it has been proved on the new diesel locomotive that the ratio of the current distribution is fully satisfied
