配(pei)電柜安裝前你必(bi)須掌握這種事兒

髙(gao)壓(ya)(ya)(ya)配(pei)電(dian)(dian)(dian)柜就是(shi)指用(yong)以(yi)供(gong)電(dian)(dian)(dian)系統發電(dian)(dian)(dian)量、輸(shu)(shu)配(pei)電(dian)(dian)(dian)、配(pei)電(dian)(dian)(dian)、電(dian)(dian)(dian)磁能變(bian)換和(he)耗費（consume)中起(qi)導通、操縱（control)或(huo)維護(hu)等功效，電(dian)(dian)(dian)壓(ya)(ya)(ya)級別(bie)(Grade)在(zai)3.6kV~550kV的家(jia)電(dian)(dian)(dian)產(chan)品(product)，主要包含高(gao)壓(ya)(ya)(ya)斷路器(circuit-breaker)、高(gao)壓(ya)(ya)(ya)隔離開(kai)關(guan)(guan)與接地裝置電(dian)(dian)(dian)源開(kai)關(guan)(guan)、高(gao)壓(ya)(ya)(ya)負荷開(kai)關(guan)(guan)、髙(gao)壓(ya)(ya)(ya)全(quan)自動重疊與按段器，髙(gao)壓(ya)(ya)(ya)實際操作組織（organization)、髙(gao)壓(ya)(ya)(ya)防爆型配(pei)電(dian)(dian)(dian)設(she)備和(he)高(gao)壓(ya)(ya)(ya)柜等幾類。高(gao)壓(ya)(ya)(ya)斷路器生產(chan)制造(Manufacture)行業(ye)(ye)是(shi)站在(zai)輸(shu)(shu)變(bian)電(dian)(dian)(dian)設(she)備(equipment)加工制造業(ye)(ye)的關(guan)(guan)鍵(jian)構(gou)成部(bu)分，在(zai)全(quan)部(bu)電(dian)(dian)(dian)力能源(Industry)中占據十(shi)分關(guan)(guan)鍵(jian)的影(ying)響力。

配電(dian)(dian)(dian)板(ban)(ban)（箱）運(yun)用(yong)不(bu)(bu)易(yi)燃(ran)原材料制(zhi)做(zuo)；觸(chu)電(dian)(dian)(dian)事故危險(xian)(xian)因素小的(de)制(zhi)造(Produce)場所(suo)(suo)和公司辦公室，可安(an)(an)(an)裝開式的(de)配電(dian)(dian)(dian)柜；在觸(chu)電(dian)(dian)(dian)事故危險(xian)(xian)因素大或工(gong)作(zuo)自然環境較弱(ruo)的(de)生產(chan)加(jia)工(gong)生產(chan)車間、鍛造、煅造、調(diao)質處理(li)、鍋爐間、木(mu)匠房(fang)等場所(suo)(suo)，應(ying)安(an)(an)(an)裝密閉式箱柜；在有導電(dian)(dian)(dian)率煙塵(形狀:固態顆(ke)粒(li))或造成(cheng)易(yi)燃(ran)易(yi)爆物品汽體的(de)風險(xian)(xian)工(gong)作(zuo)場所(suo)(suo)，務必安(an)(an)(an)裝封閉式或隔爆型的(de)電(dian)(dian)(dian)氣設備設備；配電(dian)(dian)(dian)板(ban)(ban)（箱）各電(dian)(dian)(dian)氣元器件(jian)、儀表(biao)盤、電(dian)(dian)(dian)源開關(guan)和路線應(ying)排序齊整，安(an)(an)(an)裝堅(jian)固，實際操作(zuo)便捷。[落(luo)地式安(an)(an)(an)裝的(de)板(ban)(ban)（箱）底邊應(ying)高于路面5~10 mm；操縱(zong)桿(bǐng)管(guan)理(li)中(zhong)心高寬比一(yi)般為1.2～1.5m；板(ban)(ban)（箱）正前(qian)方0.8～1.2m的(de)范圍(wei)之內無(wu)阻礙物(barrier)；維護線聯接靠譜；板(ban)(ban)（箱）之外不(bu)(bu)可有裸帶電(dian)(dian)(dian)體露出(chu)；務必安(an)(an)(an)置在板(ban)(ban)（箱）外表(biao)層或配電(dian)(dian)(dian)板(ban)(ban)上的(de)電(dian)(dian)(dian)氣元器件(jian)，務必有靠譜的(de)屏護。

 電(dian)壓(ya)配電(dian)柜安裝電(dian)表(biao)，因為電(dian)流量(Electron flow)較為大，不可(ke)以應(ying)用立即式電(dian)表(biao)，必(bi)須接互感器。

人們聯接一(yi)下整體布線(xian)基本(ben)原(yuan)理(principle)圖，一(yi)共必須接電(dian)流量(Electron flow)互(hu)感(gan)器3組(zu)6根(gen)線(xian)，電(dian)壓線(xian)3根(gen)，零線(xian)1根(gen)。如圖所(suo)示(shi)：

先將三(san)個(ge)互感器(qi)穿(chuan)在(zai)三(san)根火線(xian)(xian)零線(xian)(xian)A相B相C相上，方位是順著電流量(liang)(Electron flow)的三(san)相五線(xian)(xian)方位，相匹(pi)配互感器(qi)從P1到(dao)P2越過，P1，P2互感器(qi)有標志。

接互(hu)感(gan)器(qi)的電源線(xian)S1，S2，用1.5mm的多芯式(shi)銅(化學方程式(shi)Cu)線(xian)，將三(san)個互(hu)感(gan)器(qi)上(shang)S1、S2接線(xian)端子引出來，如圖所(suo)示：

接電(dian)壓線，從(cong)ABCN相開關電(dian)源上串聯4根(gen)電(dian)壓抽樣線，一樣應用1.5mm的多芯(xin)式(shi)銅(化學(xue)方程式(shi)Cu)線。
