1.斷開電源，檢查大連控制柜機(ji)架(jia)是否有可靠的接(jie)地，并且使接(jie)地的電阻不(bu)大于4Ω。

2.在控制柜上有不同性(xing)質(zhi)的(de)電壓(直流110伏;交(jiao)流單相(xiang)(xiang)220伏;三相(xiang)(xiang)交(jiao)流)，在維修保養時必須要分清電路，防(fang)止短路事(shi)故發(fa)生。

3.在大連控(kong)制柜(ju)上的(de)全(quan)部電器開關，都應該動(dong)作靈活可靠，無顯著噪(zao)聲，連接線結(jie)頭和接線柱應無松動(dong)的(de)現象，動(dong)觸(chu)頭連接線結(jie)頭處(chu)的(de)鋼絲應無斷裂現象。

4.用軟刷或吹(chui)風(feng)清除屏(ping)板插件和全(quan)部電磁開關零(ling)件的積塵，并檢查(cha)控(kong)制(zhi)柜內(nei)電器開關觸(chu)頭的狀態，接(jie)觸(chu)情況，線圈外(wai)表的絕緣以及機械部件的動(dong)作是否可靠。

5.更換熔絲時(shi)(shi)控(kong)制(zhi)(zhi)(zhi)，控(kong)制(zhi)(zhi)(zhi)柜(ju)(ju)怎么保養應使熔斷(duan)電(dian)流與(yu)該回路的電(dian)流相(xiang)匹配。相(xiang)關文章推薦：配電(dian)箱的油斷(duan)路器(qi)簡介熱(re)水(shui)(shui)(shui)(shui)(shui)循(xun)環(huan)泵(beng)(beng)(beng)控(kong)制(zhi)(zhi)(zhi)柜(ju)(ju):可(ke)(ke)控(kong)制(zhi)(zhi)(zhi)一(yi)(yi)(yi)臺(tai)或(huo)(huo)(huo)多(duo)臺(tai)水(shui)(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)，一(yi)(yi)(yi)般(ban)是(shi)一(yi)(yi)(yi)用(yong)(yong)一(yi)(yi)(yi)備(bei)(bei)(bei)，兩臺(tai)互(hu)為備(bei)(bei)(bei)用(yong)(yong)，工(gong)作泵(beng)(beng)(beng)故(gu)(gu)障時(shi)(shi)備(bei)(bei)(bei)用(yong)(yong)泵(beng)(beng)(beng)自(zi)動(dong)(dong)投入，也可(ke)(ke)以輪換工(gong)作。水(shui)(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)由溫度控(kong)制(zhi)(zhi)(zhi)或(huo)(huo)(huo)遠程(cheng)控(kong)制(zhi)(zhi)(zhi)。并設有(you)工(gong)作狀態(tai)(tai)（手(shou)動(dong)(dong)、自(zi)動(dong)(dong)）選擇(ze)(ze)開(kai)(kai)關，信號指示(shi)(shi)及反(fan)饋(kui)冷凍（冷卻）水(shui)(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)控(kong)制(zhi)(zhi)(zhi)柜(ju)(ju):控(kong)制(zhi)(zhi)(zhi)多(duo)臺(tai)水(shui)(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)，一(yi)(yi)(yi)般(ban)都是(shi)互(hu)為備(bei)(bei)(bei)用(yong)(yong)，輪換工(gong)作，工(gong)作泵(beng)(beng)(beng)故(gu)(gu)障時(shi)(shi)備(bei)(bei)(bei)用(yong)(yong)泵(beng)(beng)(beng)自(zi)動(dong)(dong)投入由控(kong)制(zhi)(zhi)(zhi)器(qi)或(huo)(huo)(huo)遠程(cheng)控(kong)制(zhi)(zhi)(zhi)。并設有(you)工(gong)作狀態(tai)(tai)（手(shou)動(dong)(dong)、自(zi)動(dong)(dong)）選擇(ze)(ze)開(kai)(kai)關，信號指示(shi)(shi)及反(fan)饋(kui)。排水(shui)(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)控(kong)制(zhi)(zhi)(zhi)柜(ju)(ju):可(ke)(ke)控(kong)制(zhi)(zhi)(zhi)一(yi)(yi)(yi)臺(tai)或(huo)(huo)(huo)多(duo)臺(tai)水(shui)(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)，一(yi)(yi)(yi)般(ban)是(shi)一(yi)(yi)(yi)用(yong)(yong)一(yi)(yi)(yi)備(bei)(bei)(bei)，互(hu)為備(bei)(bei)(bei)用(yong)(yong)，工(gong)作泵(beng)(beng)(beng)故(gu)(gu)障時(shi)(shi)備(bei)(bei)(bei)用(yong)(yong)泵(beng)(beng)(beng)自(zi)動(dong)(dong)投入。由單液(ye)位(wei)或(huo)(huo)(huo)多(duo)液(ye)位(wei)控(kong)制(zhi)(zhi)(zhi)還可(ke)(ke)以遠程(cheng)控(kong)制(zhi)(zhi)(zhi)。高水(shui)(shui)(shui)(shui)(shui)位(wei)啟動(dong)(dong)，低水(shui)(shui)(shui)(shui)(shui)位(wei)停泵(beng)(beng)(beng)，超高同啟，自(zi)動(dong)(dong)輪換等。并設有(you)工(gong)作狀態(tai)(tai)（手(shou)動(dong)(dong)、自(zi)動(dong)(dong)）選擇(ze)(ze)開(kai)(kai)關，信號指示(shi)(shi)及反(fan)饋(kui)。
