1、 三级视频电气安装：《施工现场姑且用电宁静手艺标准》请求51精品免费视频-51精品视频在线观看-51吃瓜网:配电箱应作分级设置，即在总配51精品免费视频-51精品视频在线观看-51吃瓜网:电箱下设(she)分派电(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)，分派电(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)上级设(she)开(kai)关箱(xiang)(xiang)(xiang)，开(kai)关箱(xiang)(xiang)(xiang)上级是用电(dian)(dian)(dian)(dian)装备，构成三级配(pei)电(dian)(dian)(dian)(dian)。如(ru)许配(pei)电(dian)(dian)(dian)(dian)条理清晰，便于(yu)办理又便于(yu)查找(zhao)毛病。同时请求，照(zhao)(zhao)明(ming)配(pei)电(dian)(dian)(dian)(dian)与(yu)能源配(pei)电(dian)(dian)(dian)(dian)别离设(she)置，自成自力体系(xi)，不(bu)至于(yu)因(yin)能源停电(dian)(dian)(dian)(dian)影响照(zhao)(zhao)明(ming)。三ꦐ级配(pei)电(dian)(dian)(dian)(dian)即总配(pei)电(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)、分派电(dian)(🍰dian)(dian)(dian)箱(xiang)(xiang)(xiang)、开(kai)关箱(xiang)(xiang)(xiang)三类标准配(pei)电(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)。开(kai)关箱(xiang)(xiang)(xiang)应(ying)合适一机(ji)、一箱(xiang)(xiang)(xiang)、一闸、一漏。

2、 两级掩护：首(shou)要(yao)(yao)指接纳泄(xie)电掩护办法在末级(ji)开关箱内(nei)加(jia)装泄(xie)电掩护器外，还要(yao)(yao)再上一级(ji)分派电箱或总配电箱中再加(jia)一级(ji)泄𓆉(xie)电掩护器，构成两级(ji)ཧ掩护。

3、 安全依据：接(jie)(jie)(jie)纳TN-S配电(dian)(dian)(dian)体(ti)(ti)系，它是(shi)把任务零(ling)(ling)线N和(he)公(gong)用掩(yan)护(hu)(hu)线PE在(zai)供(gong)电(dian)(dian)(dian)电(dian)(dian)(dian)源处(chu)严酷分(fen)隔的供(gong)电(dian)(dian)(dian)体(ti)(ti)系，也(ye)称三相五线制，它的长处(chu)是(shi)公(gong)用掩(yan)护(hu)(hu)线上无电(dian)(dian)(dian)流(liu)，此线特(te)地承接(jie)(jie𓂃)(jie)毛病电(dian)(dian)(dian)流(liu)，确(que)保其掩(yan)护(hu)(hu)装🃏(zhuang)(zhuang)配举措(cuo)，该(gai)(gai)体(ti)(ti)系任务零(ling)(ling)线与掩(yan)护(hu)(hu)零(ling)(ling)线分(fen)隔，可用顺(shun)遂装(zhuang)(zhuang)置(zhi)泄电(dian)(dian)(dian)掩(yan)护(hu)(hu)器，掩(yan)护(hu)(hu)接(jie)(jie)(jie)地和(he)掩(yan)护(hu)(hu)接(jie)(jie)(jie)零(ling)(ling)是(shi)该(gai)(gai)体(ti)(ti)系的特(te)色，是(shi)避免电(dian)(dian)(dian)器装(zhuang)(zhuang)备(bei)不测带电(dian)(dian)(dian)形成触电(dian)(dian)(dian)变乱的根基手艺办法。
