在一條(tiao)距(ju)離比較長的(de)(de)線(xian)路上有(you)多根小面積(ji)電(dian)纜(lan)(lan)(lan)(lan)(lan)往(wang)往(wang)會造成電(dian)纜(lan)(lan)(lan)(lan)(lan)使用浪(lang)費，于(yu)是在出線(xian)到用電(dian)負荷中，往(wang)往(wang)使用主(zhu)干(gan)(gan)大電(dian)纜(lan)(lan)(lan)(lan)(lan)出線(xian)，然后在接近負荷的(de)(de)時(shi)候(hou)，使用電(dian)纜(lan)(lan)(lan)(lan)(lan)分支(zhi)箱將(jiang)主(zhu)干(gan)(gan)電(dian)纜(lan)(lan)(lan)(lan)(lan)分成若(ruo)干(gan)(gan)小面積(ji)，電(dian)纜(lan)(lan)(lan)(lan)(lan)，由小面積(ji)電(dian)纜(lan)(lan)(lan)(lan)(lan)接入負荷。這(zhe)樣的(de)(de)接線(xian)方式廣泛(fan)用于(yu)城(cheng)市電(dian)網(wang)中的(de)(de)路燈等供電(dian)、小用戶供電(dian)。

施工(gong)用電(dian)(dian)(dian)配(pei)電(dian)(dian)(dian)系統應(ying)設置(zhi)總(zong)配(pei)電(dian)(dian)(dian)箱(xiang)、分配(pei)電(dian)(dian)(dian)箱(xiang)、開(kai)關(guan)箱(xiang)，并按照(zhao)“總(zong)-分-開(kai)”順序作分級設置(zhi)，并形成“三級配(pei)電(dian)(dian)(dian)”模(mo)式。施工(gong)用配(pei)電(dian)(dian)(dian)系統各配(pei)電(dian)(dian)(dian)箱(xiang)、開(kai)關(guan)箱(xiang)的安裝(zhuang)位置(zhi)要合理。總(zong)配(pei)電(dian)(dian)(dian)箱(xiang)要盡量(liang)(liang)靠近(jin)變(bian)壓器或外電(dian)(dian)(dian)源處，以便(bian)電(dian)(dian)(dian)源的引入。分配(pei)電(dian)(dian)(dian)箱(xiang)應(ying)盡量(liang)(liang)安裝(zhuang)在用電(dian)(dian)(dian)設備或負荷(he)相對集中的中心地帶，確保三相負荷(he)保持平衡。開(kai)關(guan)箱(xiang)安裝(zhuang)的位置(zhi)應(ying)視(shi)現場情(qing)況和工(gong)況盡量(liang)(liang)靠近(jin)其控制的用電(dian)(dian)(dian)設備。

配電箱是按電氣接線要求將開關設備、測量儀表，臨滄變壓器保護電器和輔助設備組裝在封閉或半封閉金屬柜中或屏幅上，構成低壓配電箱。變壓器廠家正常運(yun)(yun)行(xing)時(shi)可借(jie)(jie)助手動(dong)或自動(dong)開關接通或分斷(duan)電路。故障或不(bu)正常運(yun)(yun)行(xing)時(shi)借(jie)(jie)助保護電器切斷(duan)電路或報(bao)警(jing)。借(jie)(jie)測(ce)量儀表(biao)可顯示(shi)運(yun)(yun)行(xing)中(zhong)的(de)各種參數(shu)，還可對某(mou)些電氣參數(shu)進行(xing)調(diao)整，對偏離正常工作(zuo)狀(zhuang)態進行(xing)提示(shi)或發出信(xin)號。
