为满足我国铁路运输日益增长及安全运输的需要,根据铁道部的指示精神,大连机车车辆工厂在新造东风_4B型1606、1607号两台机车上安装了两级电阻制动装置。该两台样车已完成了地面调试及线路试运,并于1989年2月底交付机务部门运用。按铁道部要求,机车每台牵引电动机的最人制动电流应为630A±3%,最大励磁电流为
In order to meet the needs of increasing railway transportation and safe transportation in our country, according to the instructions of the Ministry of Railways, Dalian Locomotive and Rolling Stock Plant installed two-stage resistance braking device on the newly built DF-160B 1606 and 1607 locomotives. The two prototypes have completed the ground commissioning and circuit trial operation and were delivered to the maintenance department at the end of February 1989. According to the requirements of the Ministry of Railways, the locomotive braking power of each traction motor should be 630A ± 3%, the maximum excitation current
