1、 两级配电盘：《施工现场姑且用电宁静手艺标准》请求欧美性受XXXX黑人XYX性爽_欧美视频一区二区三区_欧美一区二区在线观看:配电箱应作分级设置，即在总配欧美性受XXXX黑人XYX性爽_欧美视频一区二区三区_欧美一区二区在线观看:电箱下设分(fen)派电(dian)(dian)(dian)(dian)(dian)箱(xiang)，分(fen)派电(dian)(dian)(dian)(dian)(dian)箱(xiang)上级(ji)设开关(guan)箱(xiang)，开关(guan)箱(xiang)上级(ji)是用电(dian)(dian)(dian)(dian)(dian)装备(bei)，构成三(san)(san)级(ji)配(pei)(pei)电(dian)(dian)(dian)(dian)(dian)。如许配(pei)(pei)电(dian)(dian)(dian)(dian)(dian)条理清晰，便于办理又(you)便于查找毛病。同时请求，照(zhao)(zhao)明配(pei)(pei)电(dian)(dian)(dian)(dian)(dian)与(yu)能源配(pei)(pei)电(dian)(dian)(dian)(dian)(dian)别离设置，自成自力体系，不至(zhi)于𒅌因能源停电(dian)(dian)(dian)(dian)(dian)影响照(zhao)(zhao)明。三(san)(san)级(ji)配(pei)(pei)电(dian)(dian)(dian)(dian)(dian)即总(zong)配(pei)(pei)电(dian)(dian)(dian)(dian)(dian)箱(xiang)、分(fen)派电(dian)(dian)(dian)(dian)(dian)箱(xiang)、开关(guan)箱(xiang)三(san)(san)类(lei)标准配(pei)(pei)电(dian)(dian)(dian)(dian)(dian)箱(xiang)。开关(guan)箱(xiang)应合适一(yi)(yi)机、一(yi)(yi)箱(xiang)、一(yi)(yi)闸(zha)ܫ、一(yi)(yi)漏。

2、 两级掩护：首要(yao)指接纳泄电(dian)掩护办法在末(mo)级开关箱(xiang)内加(jia)装泄电(dian)掩护器(qi)外，还要(yao)再(zai)上(shang)一(yi)级分派电(dian)箱(xiang)或总配电(dian)箱(x✤iang)中再(zai)加(jia)一(yi)级泄电(dian)掩护器(qi)，构成两级掩护。

3、 静谧方案：接(jie)纳TN-S配(pei)电(dian)(dian)(dian)体(ti)系，它(ta)(ta)是(shi)把任务(wu)零线(xian)N和公用(yꦗong)掩护(hu)线(xian)PE在供电(dian)(dian)(dian)电(dian)(dian)(dian)源处(chu)严酷分隔的供电(dian)(dian)(dian)体(ti)系，也称三相五(wu)线(xian)制，它(ta)(ta)的长处(chu)是(shi)公用(yong)掩护(hu)线(xian)上无(wu)电(dian)(dian)(dian)流，此线(xian)特地(di)(di)承接(jie)毛病电(dian)(dian)(dian)流，确保(bao)其(qi)掩护(hu)装配(pei)举措，该体(ti)系任务(wu)零线(xian)与掩护(hu)零线(xian)分隔，可用(yong)顺遂装置(zhi)泄电(dian)(dian)(dian)掩护(hu)器(qi)，掩护(hu)接(jie)地(di)(di)和掩护(h༒u)接(jie)零是(shi)该体(ti)系的特色，是(shi)避免电(dian)(dian)(dian)器(qi)装备(bei)不测带电(dian)(dian)(dian)形成(cheng)触电(dian)(dian)(dian)变乱的根基手艺办法。
