1、 3级变配电：《施工现场姑且用电宁静手艺标准》请求中文字幕AV不卡电影网_亚洲成AV人在线观看天堂无码:配电箱应作分级设置，即在总配中文字幕AV不卡电影网_亚洲成AV人在线观看天堂无码:电箱下设分(fen)派(pai)电箱(xiang)，分(fen)派(pai)电箱(xiang)上级(ji)设开关箱(xiang)，开关箱(xiang)上级(ji)是用电装备，构成三级(ji)配(pei)电。如许配(pei)电条(tiao)理清晰，便于(yu)办理又便于(yu)查找毛(mao)病。同(tong)时请求，照(zhao)明配(pei)电与能(neng)(neng)源(yuan)配(pei)电别离设置，自(zi)成自(zi)力体系(xi)，不(bu)至于(yu)因能(neng)(neng)源(yuan)停电影(ying)响照(zhao)明。三级(ji)配(pei)电即总配(pei)电箱(xiang)、分(fen)派(pai)电箱(x𒈔iang🦩)、开关箱(xiang)三类标准配(pei)电箱(xiang)。开关箱(xiang)应合适(shi)一机、一箱(xiang)、一闸(zha)、一漏。

2、 两级掩护：首(shou)要(yao)指接纳泄电(dian)掩护(hu)办法在末级(ji)开关箱(xiang)(xiang)内加(jia)装泄电(dian)掩护(hu)器外，还(hai)要(yao)再上一级(ji)分(fen)派(pai)电(dian)箱(xia൩ng)(xiang)或总(zong)配电🥂(dian)箱(xiang)(xiang)中再加(jia)一级(ji)泄电(dian)掩护(hu)器，构成(cheng)两级(ji)掩护(hu)。

3、 安全心思：接(jie)(jie)纳(na)TN-S配电(dian)(dian)(dian)体系，它是(shi)把任(ren)务(wu)(wu)零(ling)线(xian)(xian)N和(he)公用(yong)掩护(hu)(hu)线(xian)(xian)PE在供电(dian)(dian)(dian)电(dian)(dian)(dian)源处(chu)严酷(ku)分隔(ge)的供电(dian)(dian)(dian)体系，也称三相(xiang)五线(xian)(xian)制，它的长处(chu)是(shi)公用(yong)掩护(hu)(hu)线(xian)(xian)上无电(dian)(dian)(dian)流，此(ci)线(xian)(xian)特(te)地(di)承接(jie)(jie)毛(mao)病电(dian)(dian)(dian)流，确保(bao)其掩护(hu)(hu)装(zhuang)配举措，该体系任(ren)务(wu)(wu)零(ling)线(xian)(xian)与掩护(hu)ꩵ(hu)零(ling)线(xian)(xian)分隔(ge)，可用(yong)顺遂装(zhuang)置泄电(d💙ian)(dian)(dian)掩护(hu)(hu)器(qi)，掩护(hu)(hu)接(jie)(jie)地(di)和(he)掩护(hu)(hu)接(jie)(jie)零(ling)是(shi)该体系的特(te)色，是(shi)避免电(dian)(dian)(dian)器(qi)装(zhuang)备(bei)不(bu)测带(dai)电(dian)(dian)(dian)形成触电(dian)(dian)(dian)变乱的根基手艺办法。
