蘭州華美電氣設備有限公司帶你了解金昌插卡電表箱生產廠家相關信息,低壓配電箱的(de)(de)(de)設計應符(fu)合(he)(he)下列(lie)條件⑴室內(nei)溫度不(bu)(bu)得低于(yu)25℃，室外溫度不(bu)(bu)得高于(yu)30℃。⑵電(dian)氣開關、測量儀表須(xu)采(cai)用(yong)(yong)金(jin)屬封閉(bi)式金(jin)屬柜(ju)或(huo)屏幕遮(zhe)蓋板。⑶室內(nei)外空間距離不(bu)(bu)應小于(yu)0米。⑷低壓配(pei)(pei)電(dian)箱在使用(yong)(yong)中，應有防火罩。配(pei)(pei)電(dian)箱可以(yi)用(yong)(yong)于(yu)合(he)(he)理的(de)(de)(de)分(fen)配(pei)(pei)電(dian)能，方(fang)便對電(dian)路的(de)(de)(de)開合(he)(he)操(cao)作，常用(yong)(yong)的(de)(de)(de)配(pei)(pei)電(dian)箱有木制(zhi)和金(jin)屬制(zhi)兩(liang)種。設備可以(yi)用(yong)(yong)于(yu)合(he)(he)理的(de)(de)(de)分(fen)布，方(fang)便對電(dian)路的(de)(de)(de)開合(he)(he)操(cao)作。電(dian)源開關的(de)(de)(de)開合(he)(he)操(cao)作是由電(dian)源線(xian)、電(dian)容器等(deng)組成(cheng)。如果(guo)電(dian)源線(xian)的(de)(de)(de)導(dao)通性能不(bu)(bu)好，可以(yi)用(yong)(yong)一個(ge)或(huo)兩(liang)個(ge)插座來連(lian)接，但(dan)是要有防火墻。

檢查電(dian)(dian)源(yuan)是否正常工(gong)作(zuo)。電(dian)(dian)路的(de)(de)(de)設計(ji)、安裝要(yao)考慮到用(yong)(yong)戶(hu)的(de)(de)(de)切(qie)身利益。如電(dian)(dian)源(yuan)線的(de)(de)(de)接(jie)頭(tou)不(bu)符(fu)合規(gui)范要(yao)求等都會(hui)給用(yong)(yong)戶(hu)帶(dai)來不(bu)便。主要(yao)功能(neng)是用(yong)(yong)來接(jie)通和(he)關閉(bi)配電(dian)(dian)箱，在開啟(qi)時(shi)，可以將電(dian)(dian)路關閉(bi)或切(qie)斷(duan)。如果有(you)特殊情況(kuang)需要(yao)進行(xing)開機運(yun)行(xing)時(shi)，還可以使(shi)用(yong)(yong)手動(dong)或自(zi)動(dong)開啟(qi)的(de)(de)(de)方式(shi)。三(san)相(xiang)負荷的(de)(de)(de)設置應(ying)(ying)根據用(yong)(yong)電(dian)(dian)負荷變化和(he)施工(gong)現(xian)場的(de)(de)(de)實際(ji)情況(kuang)而靈活調整，避免不(bu)必要(yao)的(de)(de)(de)浪費。三(san)相(xiang)負荷在相(xiang)應(ying)(ying)范圍(wei)內應(ying)(ying)采取分段式(shi)控(kong)制，以減(jian)少(shao)對(dui)電(dian)(dian)力系(xi)統(tong)的(de)(de)(de)損害。配電(dian)(dian)箱應(ying)(ying)設有(you)專用(yong)(yong)的(de)(de)(de)接(jie)線盒，并且(qie)應(ying)(ying)該與主機相(xiang)連，不(bu)得(de)在主機與外界接(jie)觸時(shi)使(shi)用(yong)(yong)。

配電箱安裝時應(ying)(ying)當注意施(shi)工(gong)(gong)現(xian)場(chang)所有(you)(you)用電(dian)設(she)(she)備(bei)須(xu)與(yu)照(zhao)明(ming)系統(tong)同(tong)時運(yun)行(xing)，不得與(yu)照(zhao)明(ming)系統(tong)同(tong)時啟動(dong)；施(shi)工(gong)(gong)現(xian)場(chang)的(de)(de)動(dong)力(li)用電(dian)、照(zhao)明(ming)和供暖(nuan)等設(she)(she)備(bei)應(ying)(ying)該(gai)分開(kai)作(zuo)業。三相負(fu)荷回(hui)路的(de)(de)電(dian)流應(ying)(ying)該(gai)控制在(zai)適宜的(de)(de)范圍內，以確(que)保用戶(hu)和電(dian)力(li)部(bu)門(men)正常運(yun)行(xing)。電(dian)源開(kai)關箱(xiang)應(ying)(ying)盡可能設(she)(she)置在(zai)負(fu)荷相對集中的(de)(de)地(di)(di)方，避免因負(fu)荷不足而(er)導致(zhi)電(dian)壓(ya)下降。配電(dian)箱(xiang)應(ying)(ying)該(gai)安裝在(zai)用電(dian)設(she)(she)備(bei)或(huo)負(fu)荷相對集中的(de)(de)地(di)(di)方，以防(fang)止用電(dian)設(she)(she)備(bei)、負(fu)荷與(yu)照(zhao)明(ming)系統(tong)的(de)(de)不平(ping)衡。施(shi)工(gong)(gong)現(xian)場(chang)應(ying)(ying)有(you)(you)專(zhuan)人(ren)管理，并要求(qiu)施(shi)工(gong)(gong)現(xian)場(chang)保持通風良好。

配(pei)(pei)電(dian)(dian)箱(xiang)(xiang)應盡(jin)量安裝在用(yong)(yong)電(dian)(dian)設(she)(she)備或負荷(he)相對(dui)集(ji)中(zhong)(zhong)的(de)(de)中(zhong)(zhong)心地帶，確(que)保(bao)(bao)三(san)相負荷(he)保(bao)(bao)持平(ping)衡，開(kai)關箱(xiang)(xiang)安裝的(de)(de)位(wei)置應視(shi)現場情(qing)況和(he)工(gong)況盡(jin)量靠近其控制的(de)(de)用(yong)(yong)電(dian)(dian)設(she)(she)備，保(bao)(bao)證(zheng)臨時用(yong)(yong)電(dian)(dian)配(pei)(pei)電(dian)(dian)系統(tong)三(san)相負荷(he)平(ping)衡，施(shi)工(gong)現場的(de)(de)動(dong)(dong)力用(yong)(yong)電(dian)(dian)和(he)照明用(yong)(yong)電(dian)(dian)應形成兩(liang)個用(yong)(yong)電(dian)(dian)回路，動(dong)(dong)力配(pei)(pei)電(dian)(dian)箱(xiang)(xiang)與照明配(pei)(pei)電(dian)(dian)箱(xiang)(xiang)應該分別設(she)(she)置，施(shi)工(gong)現場所有用(yong)(yong)電(dian)(dian)設(she)(she)備須有各自(zi)的(de)(de)開(kai)關箱(xiang)(xiang)。配(pei)(pei)電(dian)(dian)箱(xiang)(xiang)主要用(yong)(yong)于電(dian)(dian)氣(qi)設(she)(she)備的(de)(de)檢(jian)修，如保(bao)(bao)護、測量、故障診斷等(deng)。其特(te)點是(shi)一(yi)是(shi)可以(yi)根據不同情(qing)況，選擇合適的(de)(de)配(pei)(pei)電(dian)(dian)箱(xiang)(xiang)；二是(shi)可以(yi)在不影響正常運行(xing)(xing)和(he)安全性的(de)(de)前提下(xia)(xia)，將各種配(pei)(pei)件集(ji)中(zhong)(zhong)到(dao)一(yi)個單(dan)位(wei)內進(jin)行(xing)(xing)維護。在高溫條(tiao)件下(xia)(xia)使用(yong)(yong)，需(xu)要較大(da)功率的(de)(de)開(kai)關。
