为满足电机车运行的安全性能，需要选择合适的电流隔爆型电阻器。采用铅酸蓄电池作为动力电源，电源装置提供直流电源，通过电阻器调节，控制直流牵引电动机的转速，实现电机车速度的增减，保证防爆特殊型蓄电池电机车的安全性能。%In order to meet the safety requirements of electrical locomotive operation, the current explosion-proof resistance is chosen. The lead-acid battery is used as the power supply. The power device supplies direct current. Through resistance regulate, the rotate speed of DC haulage electrical motor is controlled, which realizes speed change of locomotive and guarantees the safe performance of explosion-proof special battery electrical locomotive.
