上述方程组的解考虑了牵引发电机电枢反应的去磁作用,可以用来描述内燃机车主电路在其中一个牵引电动机发生环火时的过渡过程。根据计算结果画出曲线(图6),分析这些曲线就可作出以下结论。环火过程开始时故障电动机外电枢电路内的电流(流经主接触器的电流)迅速增大。经过5毫秒后达到6000安,经过10毫秒后达到9000安,而经过20毫秒后竟达到12500安。电 The solution of the above system of equations takes into account the demagnetization of the armature reaction of the traction generator and can be used to describe the transition of the main circuit of the diesel locomotive in the event of a ring fire on one of the traction motors. Draw the curve according to the calculation result (Fig. 6), analyze these curve and can make the following conclusion. The current inside the armature circuit outside the motor (current flowing through the main contactor) at the beginning of the torch fire process increases rapidly. After 5 milliseconds to reach 6000 A, after 10 milliseconds reached 9000 A, and after 20 milliseconds actually reached 12500 A. Electricity
