詳情請撥應用PLC改造GK1F機車電氣控制系統.主要介紹PLC控制系統的特點,以及在工礦機車電氣控制系統中的應用.PLC應用技術發展，在工業控制的眾多領域都得到廣泛的應用；是在機車電氣控制系統中大量運用。為此我們與四方機車車輛廠合作，采用PLC對現有的GK1F機車進行改造，取得了良好的效果。此舉措不可以大大地簡化線路，而且在電氣系統運行性有了顯著。同時還改變了風泵電機的起動方式，降低了故障率也使維修人員維修方便，了工作效率1.&sp;前言在2000年以前，在我部運用的內燃機車中仍有3臺機車沿用繼電器聯鎖的控制方式。這種方式，布線復雜，性差，故障查找困難，維修不便。部分觸點因長期在大電流通過的情況下動作，造成慣性灼傷，頻繁燒損。是機車風泵的控制電路中采用串電阻三級起動，易造成電阻箱燒損和起動電流大的故障。由于各種機車電氣故障居高，直接影響到機車的利用率。同時，復雜的機車邏輯電路也給增設保護裝置帶來不便。近年來，PLC應用技術發展，在工業控制的眾多領域都得到廣泛的應用；是在機車電氣控制系統中大量運用。為此我們與四方機車車輛廠合作，采用PLC對現有的GK1F機車進行改造，取得了良好的效果。此舉措不可以大大地簡化線路，而且在電氣系統運行性有了顯著。同時還改變了風泵電機的起動方式，降低了故障率也使維修人員維修方便，了工作效率。2.&sp;GK1F型機車PLC電氣控制系統設計2.1電氣系統的改造設計思路根據我部原有電氣系統為PLC控制的GK1F機車（1021—1024）和GK2B機車（1001、1002），以及資陽機車車輛廠改造的PLC控制的GK1F機車（1006—1007）；根據各種情況綜合對比我們選擇與青島四方機車車輛廠聯合對我部剩余的三臺機車進行改造。其電氣系統的設計思想與GK1F機車和GK2B機車的電氣系統相近；且各配件與這兩種機車的配件基本相同，便于維修和互換。在具體設計思想上維持原繼電器、接觸器控制系統的邏輯順序和控制原理。2.2&sp;PLC的I/O點數選定在控制電路中，輸入PLC的控制信號為32點，包括司機指令信號（如司機控制器、各琴鍵開關、按鈕開關等元件的觸點信號）和機車狀態信號（如溫度繼電器、壓力繼電器、柴油機轉速信號和機車速度信號等）。PLC輸出的控制信號點數為32點，包括動作執行元件（各接觸器線圈、電空閥及去電子調速箱的控制信號）1、schneider施耐德。產地：法國，這是興銳達值得
驕傲的牌子之一，尤其是莫迪康昆騰140系列的是從國外直接的
連施耐德中國代理也為止眼紅。這里有你想不的低
2、ge通用。產地：美國。是ic693和ic6972個系列價格
好的沒話說。價格低的讓你尖叫。鄭重聲明。是，十。
&sp;3、siemens，產地：德國。在西門子s5、s7、和停產配件
上公司的價格是屈一指的。
