配電柜安裝前你必須掌握這種事兒

髙壓(ya)配(pei)(pei)電(dian)(dian)柜就是指用以供電(dian)(dian)系統發電(dian)(dian)量、輸(shu)配(pei)(pei)電(dian)(dian)、配(pei)(pei)電(dian)(dian)、電(dian)(dian)磁能變換和(he)耗費（consume)中(zhong)起(qi)導(dao)通、操縱（control)或維護(hu)等(deng)功效，電(dian)(dian)壓(ya)級別(bie)(Grade)在3.6kV~550kV的家(jia)電(dian)(dian)產品(product)，主要包含(han)高(gao)壓(ya)斷路器(qi)(qi)(circuit-breaker)、高(gao)壓(ya)隔離開關(guan)與接(jie)地(di)裝置電(dian)(dian)源(yuan)開關(guan)、高(gao)壓(ya)負荷開關(guan)、髙壓(ya)全(quan)自動重疊與按(an)段器(qi)(qi)，髙壓(ya)實際操作組織（organization)、髙壓(ya)防(fang)爆型配(pei)(pei)電(dian)(dian)設(she)備(bei)和(he)高(gao)壓(ya)柜等(deng)幾類。高(gao)壓(ya)斷路器(qi)(qi)生產制造(Manufacture)行業是站在輸(shu)變電(dian)(dian)設(she)備(bei)(equipment)加(jia)工制造業的關(guan)鍵(jian)(jian)構成部(bu)分(fen)，在全(quan)部(bu)電(dian)(dian)力能源(yuan)(Industry)中(zhong)占(zhan)據十(shi)分(fen)關(guan)鍵(jian)(jian)的影(ying)響力。

配電(dian)(dian)板(ban)（箱(xiang)(xiang)）運(yun)用不(bu)(bu)易燃原材(cai)料制(zhi)做；觸(chu)(chu)電(dian)(dian)事(shi)(shi)故危險(xian)因(yin)素(su)小(xiao)的(de)制(zhi)造(zao)(Produce)場(chang)所(suo)和公司辦公室，可安(an)裝開式(shi)(shi)的(de)配電(dian)(dian)柜；在(zai)觸(chu)(chu)電(dian)(dian)事(shi)(shi)故危險(xian)因(yin)素(su)大或工(gong)作(zuo)自(zi)然環境(jing)較弱的(de)生產(chan)加(jia)工(gong)生產(chan)車間、鍛造(zao)、煅造(zao)、調質(zhi)處(chu)理、鍋爐(lu)間、木匠房等場(chang)所(suo)，應安(an)裝密閉式(shi)(shi)箱(xiang)(xiang)柜；在(zai)有(you)導(dao)電(dian)(dian)率煙塵(形(xing)狀:固態顆粒)或造(zao)成(cheng)易燃易爆物(wu)品汽體的(de)風險(xian)工(gong)作(zuo)場(chang)所(suo)，務必(bi)(bi)安(an)裝封閉式(shi)(shi)或隔爆型的(de)電(dian)(dian)氣(qi)設(she)備設(she)備；配電(dian)(dian)板(ban)（箱(xiang)(xiang)）各電(dian)(dian)氣(qi)元器件、儀表盤、電(dian)(dian)源開關和路線(xian)應排序齊整(zheng)，安(an)裝堅固，實際操作(zuo)便捷。[落(luo)地式(shi)(shi)安(an)裝的(de)板(ban)（箱(xiang)(xiang)）底邊(bian)應高于路面5~10 mm；操縱(zong)桿(bǐng)管(guan)理中心(xin)高寬比一般為1.2～1.5m；板(ban)（箱(xiang)(xiang)）正前方0.8～1.2m的(de)范圍之(zhi)內無阻(zu)礙物(wu)(barrier)；維護(hu)線(xian)聯接靠譜；板(ban)（箱(xiang)(xiang)）之(zhi)外不(bu)(bu)可有(you)裸帶(dai)電(dian)(dian)體露出；務必(bi)(bi)安(an)置在(zai)板(ban)（箱(xiang)(xiang)）外表層或配電(dian)(dian)板(ban)上的(de)電(dian)(dian)氣(qi)元器件，務必(bi)(bi)有(you)靠譜的(de)屏護(hu)。

電(dian)(dian)壓配電(dian)(dian)柜安裝電(dian)(dian)表(biao)，因為電(dian)(dian)流量(liang)(Electron flow)較為大，不可以應(ying)用立即式電(dian)(dian)表(biao)，必須接互(hu)感(gan)器。

人們(men)聯接一下整體布線(xian)基(ji)本原理(principle)圖(tu)，一共必(bi)須接電流量(Electron flow)互(hu)感器3組6根(gen)線(xian)，電壓線(xian)3根(gen)，零線(xian)1根(gen)。如圖(tu)所(suo)示：

先將三(san)個(ge)互(hu)感器穿在三(san)根火線(xian)(xian)零線(xian)(xian)A相B相C相上，方位(wei)是順著(zhu)電(dian)流量(liang)(Electron flow)的三(san)相五(wu)線(xian)(xian)方位(wei)，相匹配互(hu)感器從P1到P2越過(guo)，P1，P2互(hu)感器有標志。

接(jie)互(hu)感器的電源線S1，S2，用1.5mm的多芯式銅(化(hua)學方程(cheng)式Cu)線，將三個互(hu)感器上S1、S2接(jie)線端子(zi)引出(chu)來，如圖所示：

接電壓(ya)線，從ABCN相開關電源上串聯(lian)4根電壓(ya)抽(chou)樣線，一樣應用1.5mm的多(duo)芯式銅(tong)(化學方(fang)程(cheng)式Cu)線。
