为了进一步提高东风型内燃机车质量,必须消除目前10L207E型柴油机起动工况存在的问题,消灭该机车磁场削弱系统中经常出现的一、二级磁场削弱同时进行而造成牵引电动机换向不良,以及从一级磁场削弱转为全磁场工况时所经常出现的一级过渡继电器振荡而影响磁场削弱接触器的使用寿命的情况。我段对上述几条电路也进行了一些改进。
In order to further improve the quality of Dongfeng diesel locomotive, it is necessary to eliminate the existing problems of 10L207E diesel engine start-up conditions, eliminating the frequent weakening of the primary and secondary magnetic fields in the magnetic field weakening system of the locomotive, which causes the traction motor to be badly commutated at the same time, A weakening of the magnetic field into a full magnetic field conditions often occur when the first transition relay oscillation affect the magnetic field weakened the life of the contactor. I paragraph some of the above circuit also made some improvements.
