(1)施工用電(dian)配電(dian)系統應(ying)設置(zhi)總(zong)(zong)配電(dian)箱、分配電(dian)箱、開關箱,并按照“總(zong)(zong)-分-開”順序作分級設置(zhi),并形成“三級配電(dian)”模式。
(2)施工用配電(dian)(dian)系統各配電(dian)(dian)箱(xiang)、開關箱(xiang)的安(an)(an)裝(zhuang)位置要合理。總配電(dian)(dian)箱(xiang)要盡量(liang)靠近變壓(ya)器(qi)或(huo)外電(dian)(dian)源處(chu),以便電(dian)(dian)源的引入。分配電(dian)(dian)箱(xiang)應盡量(liang)安(an)(an)裝(zhuang)在用電(dian)(dian)設(she)備(bei)或(huo)負荷相對集中的中心(xin)地帶,確保三相負荷持平衡。開關(guan)箱安裝的位置應視現場情況和工(gong)況盡量靠(kao)近其控(kong)制的用電設備。
(3)保證臨時用(yong)電配電系(xi)統三相負荷平(ping)衡,施工現場(chang)的動(dong)力用(yong)電和照明用(yong)電應形成兩個用(yong)電回路,動(dong)力配電箱與照明配電箱應該分別設(she)置。
(4)施工(gong)現場所(suo)有用電(dian)設備(bei)必(bi)須有各自的專(zhuan)用的開關(guan)箱。
(5)各級配電(dian)(dian)箱(xiang)(xiang)(xiang)的箱(xiang)(xiang)(xiang)體和內部設置必須符合(he)安全規(gui)定(ding),開關(guan)電(dian)(dian)器應標明用途,箱(xiang)(xiang)(xiang)體應統一(yi)編號。停止使用的配電(dian)(dian)箱(xiang)(xiang)(xiang)應切斷電(dian)(dian)源,箱(xiang)(xiang)(xiang)門上鎖。固定(ding)式(shi)配電(dian)(dian)箱(xiang)(xiang)(xiang)應設置圍(wei)欄,并(bing)有防雨防砸措施。
(6)配(pei)電(dian)箱與配(pei)電(dian)柜的區別。根據GB/T20641-2006《低壓成套(tao)開關(guan)設備(bei)和(he)控制設備(bei)空殼體的一般要(yao)求(qiu)》配(pei)(pei)電(dian)(dian)箱(xiang)一(yi)般是家庭用的,而配(pei)(pei)電(dian)(dian)柜則多用在集中供電(dian)(dian)中,比如說工業用電(dian)(dian)和建筑用電(dian)(dian)等,配(pei)(pei)電(dian)(dian)箱(xiang)和配(pei)(pei)電(dian)(dian)柜都(dou)屬于成(cheng)套設(she)備,配(pei)(pei)電(dian)(dian)箱(xiang)屬于低(di)(di)壓(ya)成(cheng)套設(she)備,配(pei)(pei)電(dian)(dian)柜有高(gao)壓(ya)有低(di)(di)壓(ya)。
