自部发(74)字247号文件以来,各内燃机车厂、段都相继在东风型内燃机车上加装了主回路电流分配表,以监视三组牵引电动机的工作,从而提高运用的可靠性,为“防患于未然”创造了有利条件。尽管加装电流分配表的设计方案互有不同,各有优点,但是,对于三回路电流分配均匀度的计算方法和要求是一致的。目前,各内燃段为了提高检修质量,开展机车轮修、架修的“一次成功”活动,其中包括处理电流分配一次成功。这就要求在机车不起动的情况下,以测定各支路电阻值的方法,来计算三回路电流分配均匀度。对这个方法,有过很多经验介绍,都值得借鉴。我认为《内燃机车》杂志1978年第4期上发表的《牵引电动机电流分配不均匀的处理》
Since the document No. 247 issued by the Ministry of Posts and Telecommunications, all diesel locomotive factories and sections have successively installed the main circuit current distribution table on the Dongfeng diesel locomotive to monitor the work of the three traction motors so as to improve the reliability of the application, For “take preventive measures” to create favorable conditions. Although the designs of the current distribution meter are different from each other, each has its own advantages. However, the calculation methods and requirements for the current distribution uniformity of the three circuits are consistent. At present, in order to improve the quality of overhaul, each internal combustion section carries out “one successful” activity of locomotive wheel repair and maintenance, which includes handling the current distribution once successfully. This requires the locomotive does not start the case, to determine the resistance of each branch method to calculate the current distribution of the three loop uniformity. Have a lot of experience on this method, are worth learning. I think “Diesel Locomotive” Magazine No. 4, 1978 on the published “traction motor current distribution uneven treatment”
