工業冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)機(ji)(ji)組應(ying)用(yong)(yong)廣泛，在有工業的地方就要用(yong)(yong)到冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)設備，如：化(hua)工冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)、電(dian)鍍冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)、食(shi)品冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)、電(dian)子加工冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)、模具冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)、印刷冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)等，而且(qie)大(da)部分行(xing)業對于工業冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)要求很(hen)高的，大(da)部分客(ke)戶(hu)的要求都是24小時(shi)運轉，所以對冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)的電(dian)源(yuan)電(dian)壓要求也很(hen)高，如果(guo)冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)的幾(ji)相電(dian)壓不平衡太(tai)于2%時(shi)，操作時(shi)有可能(neng)損壞冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)，所以要控制好冷(leng)(leng)水(shui)(shui)(shui)(shui)機(ji)(ji)。
冷(leng)水(shui)機電源電壓的檢測(ce)
如果冷水機標(biao)準(zhun)電壓為(wei)(wei)3相，380V，50Hz，測得UAB=376V，UAC=379V，UBC=385V。得出平(ping)(ping)均電壓=(376+379+385)/3=380V：確定與平(ping)(ping)均電壓的(de)偏(pian)差(cha)值：△UAB=380-376=4V，△UAC=380-379=1V，△UBC=385-380=5V，最大(da)偏(pian)差(cha)值為(wei)(wei)5V，5/380=1.3%，得出最大(da)相電壓不(bu)平(ping)(ping)衡為(wei)(wei)1.3%。
如果(guo)測(ce)得該電(dian)源(yuan)和(he)電(dian)壓(ya)在正(zheng)常(chang)范圍內，這樣就(jiu)(jiu)可以正(zheng)常(chang)開機。如果(guo)冷(leng)水(shui)機電(dian)源(yuan)控制不好，那么損壞的(de)話就(jiu)(jiu)會(hui)有(you)很高的(de)一個維修成本，按正(zheng)常(chang)來講的(de)話電(dian)壓(ya)都(dou)會(hui)比較(jiao)正(zheng)常(chang)。
冷水機的(de)電(dian)(dian)源電(dian)(dian)壓(ya)最大(da)可允許(xu)的(de)相電(dian)(dian)壓(ya)不(bu)(bu)平(ping)(ping)衡(heng)為2%，相電(dian)(dian)流不(bu)(bu)平(ping)(ping)衡(heng)為10%。注(zhu)：當(dang)相電(dian)(dian)壓(ya)不(bu)(bu)平(ping)(ping)衡(heng)大(da)于2%，絕對不(bu)(bu)能開機操作。
冷(leng)水(shui)機(ji)的(de)工作電(dian)源是3相(xiang)，380V，50Hz。在運行(xing)冷(leng)水(shui)機(ji)前，需要檢查電(dian)控(kong)(kong)(kong)柜中電(dian)源部分和控(kong)(kong)(kong)制(zhi)(zhi)部分有無異(yi)常(chang)(chang)，并固緊接(jie)(jie)線(xian)端子，包括總電(dian)源接(jie)(jie)線(xian)銅(tong)排，自動(dong)空氣(qi)斷路器(qi)(空氣(qi)開(kai)關)，Δ-Δ或(huo)Y-Δ壓(ya)縮機(ji)啟(qi)動(dong)電(dian)氣(qi)裝置，PLC觸摸屏，靶流(liu)開(kai)關，冷(leng)凍水(shui)泵(beng)，冷(leng)卻水(shui)泵(beng)聯動(dong)控(kong)(kong)(kong)制(zhi)(zhi)線(xian)(控(kong)(kong)(kong)制(zhi)(zhi)接(jie)(jie)點為(wei)無源接(jie)(jie)點)，溫度傳感器(qi)，冷(leng)凍，冷(leng)卻水(shui)泵(beng)，冷(leng)卻水(shui)塔(ta)聯動(dong)控(kong)(kong)(kong)制(zhi)(zhi)線(xian)(控(kong)(kong)(kong)制(zhi)(zhi)接(jie)(jie)點為(wei)無源接(jie)(jie)點)，電(dian)控(kong)(kong)(kong)儀表等等節點。待確(que)認好后，方可執行(xing)開(kai)機(ji)操作，確(que)保(bao)冷(leng)水(shui)機(ji)組(zu)正常(chang)(chang)運行(xing)。
冷(leng)水機組(zu)屬于大功(gong)率機器(qi)，電壓(ya)基本都(dou)是工業電壓(ya)，380V，所以(yi)在(zai)安裝冷(leng)水機時最好安裝穩壓(ya)器(qi)。
