工(gong)業(ye)冷(leng)(leng)(leng)水(shui)(shui)機(ji)機(ji)組應用(yong)廣泛，在有工(gong)業(ye)的(de)地(di)方就要(yao)用(yong)到(dao)冷(leng)(leng)(leng)水(shui)(shui)機(ji)設備，如：化工(gong)冷(leng)(leng)(leng)水(shui)(shui)機(ji)、電(dian)(dian)(dian)鍍冷(leng)(leng)(leng)水(shui)(shui)機(ji)、食品冷(leng)(leng)(leng)水(shui)(shui)機(ji)、電(dian)(dian)(dian)子(zi)加工(gong)冷(leng)(leng)(leng)水(shui)(shui)機(ji)、模具(ju)冷(leng)(leng)(leng)水(shui)(shui)機(ji)、印刷(shua)冷(leng)(leng)(leng)水(shui)(shui)機(ji)等，而且(qie)大部(bu)分行業(ye)對于工(gong)業(ye)冷(leng)(leng)(leng)水(shui)(shui)機(ji)要(yao)求很(hen)(hen)高(gao)的(de)，大部(bu)分客戶的(de)要(yao)求都(dou)是24小(xiao)時運轉，所以(yi)對冷(leng)(leng)(leng)水(shui)(shui)機(ji)的(de)電(dian)(dian)(dian)源電(dian)(dian)(dian)壓要(yao)求也很(hen)(hen)高(gao)，如果(guo)冷(leng)(leng)(leng)水(shui)(shui)機(ji)的(de)幾相電(dian)(dian)(dian)壓不平衡太于2%時，操作時有可(ke)能損壞冷(leng)(leng)(leng)水(shui)(shui)機(ji)，所以(yi)要(yao)控制好冷(leng)(leng)(leng)水(shui)(shui)機(ji)。
冷水機電(dian)源電(dian)壓的檢測
如果冷水機標(biao)準電(dian)(dian)壓(ya)為(wei)3相，380V，50Hz，測(ce)得UAB=376V，UAC=379V，UBC=385V。得出平均電(dian)(dian)壓(ya)=(376+379+385)/3=380V：確(que)定與平均電(dian)(dian)壓(ya)的偏差值：△UAB=380-376=4V，△UAC=380-379=1V，△UBC=385-380=5V，最大偏差值為(wei)5V，5/380=1.3%，得出最大相電(dian)(dian)壓(ya)不平衡(heng)為(wei)1.3%。
如果測(ce)得該電(dian)源和電(dian)壓在正常(chang)(chang)范圍(wei)內，這樣(yang)就可以(yi)正常(chang)(chang)開機。如果冷水機電(dian)源控制不好，那么損壞的話就會有很(hen)高(gao)的一個維(wei)修成(cheng)本，按正常(chang)(chang)來講的話電(dian)壓都會比較正常(chang)(chang)。
冷(leng)水機的電源電壓最大可允許的相(xiang)電壓不(bu)(bu)平(ping)(ping)(ping)衡為(wei)2%，相(xiang)電流不(bu)(bu)平(ping)(ping)(ping)衡為(wei)10%。注：當相(xiang)電壓不(bu)(bu)平(ping)(ping)(ping)衡大于2%，絕對不(bu)(bu)能開機操作。
冷(leng)(leng)水(shui)機的工作電(dian)(dian)(dian)源(yuan)(yuan)是3相，380V，50Hz。在運(yun)行冷(leng)(leng)水(shui)機前(qian)，需(xu)要檢(jian)查(cha)電(dian)(dian)(dian)控(kong)柜中電(dian)(dian)(dian)源(yuan)(yuan)部分和(he)控(kong)制部分有無(wu)異(yi)常(chang)，并固緊接(jie)線端子，包(bao)括(kuo)總(zong)電(dian)(dian)(dian)源(yuan)(yuan)接(jie)線銅(tong)排，自動(dong)空氣斷路器(空氣開關(guan))，Δ-Δ或Y-Δ壓縮機啟動(dong)電(dian)(dian)(dian)氣裝置，PLC觸摸屏，靶(ba)流開關(guan)，冷(leng)(leng)凍(dong)水(shui)泵，冷(leng)(leng)卻水(shui)泵聯(lian)動(dong)控(kong)制線(控(kong)制接(jie)點為(wei)無(wu)源(yuan)(yuan)接(jie)點)，溫(wen)度傳感器，冷(leng)(leng)凍(dong)，冷(leng)(leng)卻水(shui)泵，冷(leng)(leng)卻水(shui)塔聯(lian)動(dong)控(kong)制線(控(kong)制接(jie)點為(wei)無(wu)源(yuan)(yuan)接(jie)點)，電(dian)(dian)(dian)控(kong)儀表(biao)等等節點。待確認好后，方可執行開機操(cao)作，確保冷(leng)(leng)水(shui)機組(zu)正(zheng)常(chang)運(yun)行。
冷(leng)水機(ji)組屬(shu)于大功率機(ji)器，電壓(ya)基本(ben)都是工業電壓(ya)，380V，所以在安裝(zhuang)冷(leng)水機(ji)時最好(hao)安裝(zhuang)穩壓(ya)器。
