工(gong)(gong)業(ye)冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)(ji)機(ji)(ji)(ji)組(zu)應用(yong)廣泛，在有工(gong)(gong)業(ye)的(de)地方就要(yao)(yao)用(yong)到冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)(ji)設備(bei)，如：化工(gong)(gong)冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)(ji)、電(dian)鍍(du)冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)(ji)、食品冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)(ji)、電(dian)子(zi)加工(gong)(gong)冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)(ji)、模具冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)(ji)、印刷(shua)冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)(ji)等，而且大部分行業(ye)對于工(gong)(gong)業(ye)冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)(ji)要(yao)(yao)求很高的(de)，大部分客戶的(de)要(yao)(yao)求都是(shi)24小時(shi)運(yun)轉，所(suo)以對冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)(ji)的(de)電(dian)源電(dian)壓要(yao)(yao)求也(ye)很高，如果冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)(ji)的(de)幾相電(dian)壓不平衡(heng)太于2%時(shi)，操作時(shi)有可能(neng)損壞(huai)冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)(ji)，所(suo)以要(yao)(yao)控制好冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)(ji)。
冷(leng)水機電(dian)源(yuan)電(dian)壓(ya)的(de)檢測
如果(guo)冷(leng)水機(ji)標準電(dian)壓(ya)為3相，380V，50Hz，測得(de)UAB=376V，UAC=379V，UBC=385V。得(de)出平(ping)均(jun)電(dian)壓(ya)=(376+379+385)/3=380V：確定與平(ping)均(jun)電(dian)壓(ya)的偏差值(zhi)：△UAB=380-376=4V，△UAC=380-379=1V，△UBC=385-380=5V，最大(da)偏差值(zhi)為5V，5/380=1.3%，得(de)出最大(da)相電(dian)壓(ya)不平(ping)衡為1.3%。
如果(guo)測得該電源和電壓(ya)在(zai)正常范圍內，這樣就可以(yi)正常開(kai)機。如果(guo)冷水機電源控制不好(hao)，那么損壞(huai)的(de)話(hua)就會有(you)很高的(de)一個維修成本，按正常來講(jiang)的(de)話(hua)電壓(ya)都(dou)會比(bi)較正常。
冷水機(ji)的(de)電(dian)源電(dian)壓最(zui)大(da)可允許(xu)的(de)相(xiang)電(dian)壓不平(ping)衡(heng)為(wei)2%，相(xiang)電(dian)流不平(ping)衡(heng)為(wei)10%。注(zhu)：當(dang)相(xiang)電(dian)壓不平(ping)衡(heng)大(da)于2%，絕對(dui)不能(neng)開機(ji)操作。
冷水機(ji)的工作電(dian)(dian)源(yuan)(yuan)是3相，380V，50Hz。在運行(xing)冷水機(ji)前，需(xu)要(yao)檢(jian)查電(dian)(dian)控(kong)柜中電(dian)(dian)源(yuan)(yuan)部(bu)分(fen)和控(kong)制(zhi)(zhi)部(bu)分(fen)有無(wu)異常，并(bing)固緊接線(xian)端(duan)子，包括總電(dian)(dian)源(yuan)(yuan)接線(xian)銅排(pai)，自動(dong)空氣(qi)斷(duan)路(lu)器(空氣(qi)開(kai)關(guan))，Δ-Δ或(huo)Y-Δ壓縮機(ji)啟動(dong)電(dian)(dian)氣(qi)裝置(zhi)，PLC觸(chu)摸屏，靶流開(kai)關(guan)，冷凍(dong)水泵(beng)，冷卻水泵(beng)聯(lian)動(dong)控(kong)制(zhi)(zhi)線(xian)(控(kong)制(zhi)(zhi)接點(dian)(dian)為無(wu)源(yuan)(yuan)接點(dian)(dian))，溫度傳感器，冷凍(dong)，冷卻水泵(beng)，冷卻水塔聯(lian)動(dong)控(kong)制(zhi)(zhi)線(xian)(控(kong)制(zhi)(zhi)接點(dian)(dian)為無(wu)源(yuan)(yuan)接點(dian)(dian))，電(dian)(dian)控(kong)儀表等等節(jie)點(dian)(dian)。待(dai)確認好后(hou)，方(fang)可執(zhi)行(xing)開(kai)機(ji)操作，確保(bao)冷水機(ji)組正常運行(xing)。
冷(leng)水機組屬于(yu)大功率(lv)機器，電壓基本(ben)都是工(gong)業電壓，380V，所(suo)以在安(an)裝(zhuang)冷(leng)水機時最好安(an)裝(zhuang)穩壓器。
