详情请拨应用PLC改造GK1F机车电气控制系统.主要介绍PLC控制系统的特点,以及在工矿机车电气控制系统中的应用.PLC应用技术发展，在工业控制的众多领域都得到广泛的应用；是在机车电气控制系统中大量运用。为此我们与四方机车车辆厂合作，采用PLC对现有的GK1F机车进行改造，取得了良好的效果。此举措不可以大大地简化线路，而且在电气系统运行性有了显著。同时还改变了风泵电机的起动方式，降低了故障率也使维修人员维修方便，了工作效率1.&sp;前言在2000年以前，在我部运用的内燃机车中仍有3台机车沿用继电器联锁的控制方式。这种方式，布线复杂，性差，故障查找困难，维修不便。部分触点因长期在大电流通过的情况下动作，造成惯性灼伤，频繁烧损。是机车风泵的控制电路中采用串电阻三级起动，易造成电阻箱烧损和起动电流大的故障。由于各种机车电气故障居高，直接影响到机车的利用率。同时，复杂的机车逻辑电路也给增设保护装置带来不便。近年来，PLC应用技术发展，在工业控制的众多领域都得到广泛的应用；是在机车电气控制系统中大量运用。为此我们与四方机车车辆厂合作，采用PLC对现有的GK1F机车进行改造，取得了良好的效果。此举措不可以大大地简化线路，而且在电气系统运行性有了显著。同时还改变了风泵电机的起动方式，降低了故障率也使维修人员维修方便，了工作效率。2.&sp;GK1F型机车PLC电气控制系统设计2.1电气系统的改造设计思路根据我部原有电气系统为PLC控制的GK1F机车（1021—1024）和GK2B机车（1001、1002），以及资阳机车车辆厂改造的PLC控制的GK1F机车（1006—1007）；根据各种情况综合对比我们选择与青岛四方机车车辆厂联合对我部剩余的三台机车进行改造。其电气系统的设计思想与GK1F机车和GK2B机车的电气系统相近；且各配件与这两种机车的配件基本相同，便于维修和互换。在具体设计思想上维持原继电器、接触器控制系统的逻辑顺序和控制原理。2.2&sp;PLC的I/O点数选定在控制电路中，输入PLC的控制信号为32点，包括司机指令信号（如司机控制器、各琴键开关、按钮开关等元件的触点信号）和机车状态信号（如温度继电器、压力继电器、柴油机转速信号和机车速度信号等）。PLC输出的控制信号点数为32点，包括动作执行元件（各接触器线圈、电空阀及去电子调速箱的控制信号）1、schneider施耐德。产地：法国，这是兴锐达值得
骄傲的牌子之一，尤其是莫迪康昆腾140系列的是从国外直接的
连施耐德中国代理也为止眼红。这里有你想不的低
2、ge通用。产地：美国。是ic693和ic6972个系列价格
好的没话说。价格低的让你尖叫。郑重声明。是，十。
&sp;3、siemens，产地：德国。在西门子s5、s7、和停产配件
上公司的价格是屈一指的。
&sp;
4、foxboro；5、abb；6、ab……优势配件实在太多，小郑在这就不多做赘述，
我相信你已经迫不及待要打电话来质询了：
