指除安裝面外，其它所有側面都被封閉起來的一種低壓開關柜。這種柜子的開關、保護和監測控制等電氣元件，貴陽開關柜均安裝在一個用鋼或絕緣材料制成的封閉外殼內，可靠墻或離墻安裝。開關柜價格柜內每(mei)條回路之間可(ke)以(yi)不加隔離(li)措施，也可(ke)以(yi)采用(yong)接地(di)的(de)金屬板(ban)或絕(jue)緣板(ban)進行(xing)隔離(li)。通常門與主開關(guan)(guan)操(cao)作(zuo)有機械聯鎖。另外還有防護式(shi)臺型(xing)開關(guan)(guan)柜（即(ji)控(kong)制臺）】面板(ban)上裝(zhuang)有控(kong)制、測(ce)量、信號等電器。防護式(shi)開關(guan)(guan)柜主要(yao)用(yong)作(zuo)工(gong)藝現場(chang)的(de)配電裝(zhuang)置。

施工用電(dian)配電(dian)系(xi)統(tong)應(ying)設(she)置(zhi)(zhi)總(zong)配電(dian)箱(xiang)、分配電(dian)箱(xiang)、開關箱(xiang)，并按照“總(zong)-分-開”順序作分級(ji)設(she)置(zhi)(zhi)，并形(xing)成(cheng)“三級(ji)配電(dian)”模式。施工用配電(dian)系(xi)統(tong)各配電(dian)箱(xiang)、開關箱(xiang)的(de)安(an)裝位(wei)置(zhi)(zhi)要合理。總(zong)配電(dian)箱(xiang)要盡(jin)(jin)量(liang)靠近(jin)變壓器或外電(dian)源處，以便電(dian)源的(de)引入。分配電(dian)箱(xiang)應(ying)盡(jin)(jin)量(liang)安(an)裝在用電(dian)設(she)備或負荷相對集中(zhong)的(de)中(zhong)心地(di)帶，確(que)保三相負荷保持平衡。開關箱(xiang)安(an)裝的(de)位(wei)置(zhi)(zhi)應(ying)視現場情(qing)況(kuang)和(he)工況(kuang)盡(jin)(jin)量(liang)靠近(jin)其控(kong)制的(de)用電(dian)設(she)備。

改進原配電(dian)(dian)箱(xiang)的低(di)壓(ya)電(dian)(dian)容(rong)器(qi)(qi)組的接線方式(shi)，將(jiang)其(qi)安裝(zhuang)位置由交(jiao)流接觸器(qi)(qi)上樁頭，改成(cheng)接在配電(dian)(dian)箱(xiang)低(di)壓(ya)進線與計(ji)量(liang)表計(ji)之間。防止因運(yun)(yun)行中電(dian)(dian)容(rong)器(qi)(qi)電(dian)(dian)路(lu)發生缺相故障(zhang)或電(dian)(dian)容(rong)器(qi)(qi)損(sun)壞時(shi)，造成(cheng)計(ji)量(liang)裝(zhuang)置計(ji)量(liang)不(bu)準確。此外，電(dian)(dian)容(rong)器(qi)(qi)選(xuan)擇型(xing)號(hao)應(ying)為BSMJ系(xi)列產品，以(yi)保證元件質量(liang)可靠、安全運(yun)(yun)行。

在一條距離比較長的(de)線路(lu)上有多根小(xiao)面積(ji)電(dian)(dian)(dian)(dian)纜(lan)往往會造成電(dian)(dian)(dian)(dian)纜(lan)使(shi)用(yong)(yong)浪費，于(yu)是(shi)在出線到用(yong)(yong)電(dian)(dian)(dian)(dian)負(fu)荷中(zhong)，往往使(shi)用(yong)(yong)主(zhu)干大電(dian)(dian)(dian)(dian)纜(lan)出線，然后在接(jie)(jie)近負(fu)荷的(de)時(shi)候(hou)，使(shi)用(yong)(yong)電(dian)(dian)(dian)(dian)纜(lan)分支箱將主(zhu)干電(dian)(dian)(dian)(dian)纜(lan)分成若干小(xiao)面積(ji)，電(dian)(dian)(dian)(dian)纜(lan)，由小(xiao)面積(ji)電(dian)(dian)(dian)(dian)纜(lan)接(jie)(jie)入(ru)負(fu)荷。這樣的(de)接(jie)(jie)線方式廣泛用(yong)(yong)于(yu)城市電(dian)(dian)(dian)(dian)網中(zhong)的(de)路(lu)燈等供(gong)電(dian)(dian)(dian)(dian)、小(xiao)用(yong)(yong)戶供(gong)電(dian)(dian)(dian)(dian)。

搬運材料、傳遞工具、拆(chai)換(huan)(huan)部件、今天你去(qu)搶修(xiu)到我來安(an)裝(zhuang)、你累了(le)換(huan)(huan)我來。就這樣，一(yi)(yi)個接著(zhu)一(yi)(yi)個的(de)(de)(de)配電箱(xiang)在師(shi)傅(fu)們輪換(huan)(huan)著(zhu)的(de)(de)(de)手(shou)掌下組裝(zhuang)了(le)起來。經過3天的(de)(de)(de)努力，所需更換(huan)(huan)的(de)(de)(de)配電箱(xiang)已經全部組裝(zhuang)完畢，為本次更換(huan)(huan)配電箱(xiang)工作做好(hao)了(le)前期準備，大家的(de)(de)(de)臉(lian)上露出了(le)開心的(de)(de)(de)笑容。

由于(yu)電(dian)(dian)動汽車每(mei)天需要補充(chong)(chong)(chong)大量電(dian)(dian)能(neng)，經營充(chong)(chong)(chong)電(dian)(dian)站(zhan)就可以獲得巨大的充(chong)(chong)(chong)電(dian)(dian)服(fu)務收益。相對于(yu)加(jia)油站(zhan)，電(dian)(dian)能(neng)比較安全和方便(bian)，可在各地(di)大量安裝(zhuang)設(she)(she)置充(chong)(chong)(chong)電(dian)(dian)站(zhan)。根據投資(zi)規(gui)模，小到社區慢速(su)(su)充(chong)(chong)(chong)電(dian)(dian)樁，大到公路快(kuai)速(su)(su)充(chong)(chong)(chong)電(dian)(dian)站(zhan)，單站(zhan)經營，組網經營均可。對于(yu)充(chong)(chong)(chong)電(dian)(dian)站(zhan)市(shi)場的開放，國家(jia)電(dian)(dian)網以后可能(neng)更(geng)多地(di)會偏向服(fu)務和電(dian)(dian)力供應，讓充(chong)(chong)(chong)電(dian)(dian)站(zhan)建設(she)(she)更(geng)充(chong)(chong)(chong)分地(di)與市(shi)場融合，大家(jia)都將(jiang)是同一個市(shi)場的競爭者。因此提(ti)(ti)前準備、提(ti)(ti)前規(gui)劃，對從事電(dian)(dian)池生產(chan)的企業(ye)來說很重要。充(chong)(chong)(chong)換(huan)電(dian)(dian)市(shi)場，政策有(you)傾(qing)斜，市(shi)場有(you)潛力，投資(zi)又少，將(jiang)面臨較大的商機(ji)。
