1、韶山型电力机车重联控制研究韶山型电力机车重联控制研究研究生： 导 师： 北京交通大学机械与电子控制工程学院 年 月摘 要（中文）SS3型电力机车重联控制系统中所说的机车重联牵引与一般意义上的机车重联牵引不同。一般意义上的机车重联牵引，由于是个别控制，难以达到牵引和制动的均匀和同步控制，重联控制系统可以在重联双机的任一个机车上实现两机车牵引和制动的均匀和同步控制，以最大限度地发挥牵引效率。SS3机车采用大功率硅整流管和晶闸管组成的桥式全波整流电路。调压整流电路是晶闸管级间平滑调压系统及采用恒流限压控制,使机车具有无级加速特性。SS3机车重联控制系统的设计必须充分考虑到与原机车电气线路及部件的兼容

2、性，尽可能不改变单机原电气控制线路的逻辑性，使设计后的电力机车既能重联运行，也能单机运行，单机操作时的单机性能不发生任何变化。两台电力机车重联以后，在任何一台机车的任意一个司机室均能方便的控制所有重联机车的运行，实现两台电力机车协调一致地进行牵引和制动。另外，重联控制系统的设计尽可能简单，以方便司乘人员掌握和操作。重联控制系统的设计与研究与SS3电力机车控制的特点结合比较紧密。首先是考虑到了重联两机车中的任何一台机车电器动作的快慢不能影响另一台机车上电器的正常动作次序。其次是在控制电路中很好的避免迂回电路的产生，因为它们可能引起机车上电路电器的误动作。对于SS3电力机车在双机重联牵引时，调速电

3、路中两位转换开关的控制、整备电路中受电弓的升降以及制动电路中撒砂的控制都有一定的特点，与电力机车不同端联挂有关。因此，重联控制系统设计方案中必须考虑适应同车端和不同车端两种连挂方式。电力机车重联控制过程中，为保证发挥最大牵引力，要求两台机车必须是有相同的运行速度，也就是要求两台机车有相同的运行级位。SS3电力机车是采用调压开关分接成8级步进和级间通过电子电路恒流调压调速的方式进行速度调节控制，这种调速方式的重联控制在国内尚居首次，重联控制设计与研究过程中很好的解决了调压开关级位转换时重联两机车的同步问题，实现了调压开关的无电弧转换。重联控制系统完成了五个部分控制的内容，一是机车整备控制，即完成

4、机车起动前的各项预备性操作，如升受电弓、合主断路器、起动各辅机等。二是机车调速控制，完成机车工况选择、运行方向选择及速度调节的重联控制。三是机车保护控制，即保护与机车主电路、辅助电路有关的执行重联控制。四是信号显示的重联控制。五是电空制动的控制，即DK-1制动机的控制。重联控制方案在成都铁路局遵义机务段所辖的两台SS3电力机车上进行工程施工、调试和试运行，获得初步成功，效果反馈很好。目前，该方案正在试运行过程中逐步走向完善。关键词： 电力机车 控制 电气线路 重联摘 要（英文）Coupling and traction of double-headed control system of SS
