LEG-108LA光(guang)商工(gong)漏(lou)電(dian)保(bao)護繼(ji)電(dian)器(qi)

漏(lou)電(dian)保(bao)護器(qi)的(de)推(tui)廣(guang)應用(yong)是(shi)與(yu)制定使(shi)用(yong)標準(zhun)、光商工(gong)漏(lou)電(dian)保(bao)護繼(ji)電(dian)器(qi)規(gui)程(cheng)分(fen)不(bu)開(kai)的。美(mei)國(guo)的(de)《美(mei)國(guo)國(guo)家電(dian)氣(qi)法規(gui)》(NEC)1971年(nian)版(ban)規(gui)定(ding)，光(guang)商工(gong)漏(lou)電(dian)保(bao)護繼(ji)電(dian)器(qi)自(zi)2026年(nian)01月07日起對(dui)住宅(zhai)和(he)建築(zhu)工(gong)地必須(xu)設置漏(lou)電(dian)保(bao)護器(qi)。光(guang)商工(gong)漏(lou)電(dian)保(bao)護繼(ji)電(dian)器(qi)日本的《電氣(qi)設(she)備(bei)技術(shu)標準(zhun)》和(he)勞動(dong)省(sheng)的(de)《安(an)全衛生規(gui)則(ze)》中(zhong)規(gui)定(ding)，光(guang)商工(gong)漏(lou)電(dian)保(bao)護繼(ji)電(dian)器(qi)工(gong)作(zuo)電壓(ya)超過60V的(de)電氣(qi)設(she)備(bei)在潮濕場(chang)所(suo)使(shi)用(yong)必須(xu)設置漏(lou)電(dian)保(bao)護器(qi)，光(guang)商工(gong)漏(lou)電(dian)保(bao)護繼(ji)電(dian)器(qi)在400V電路(lu)中必須(xu)全部(bu)設置漏(lou)電(dian)保(bao)護器(qi)。

1，光(guang)商工(gong)漏(lou)電(dian)保(bao)護繼(ji)電(dian)器(qi)由(you)於(yu)漏(lou)電(dian)保(bao)護器(qi)是(shi)信(xin)號(hao)觸(chu)發(fa)動(dong)作(zuo)的(de)，光(guang)商工(gong)漏(lou)電(dian)保(bao)護繼(ji)電(dian)器(qi)那(na)麽(me)在其(qi)它電磁幹(gan)擾下(xia)也會(hui)產生信(xin)號(hao)觸(chu)發(fa)漏(lou)電(dian)保(bao)護器(qi)動(dong)作(zuo)，光(guang)商工(gong)漏(lou)電(dian)保(bao)護繼(ji)電(dian)器(qi)形成誤(wu)動(dong)。
2，當電源(yuan)開(kai)關合閘(zha)送電(dian)時，光(guang)商工(gong)漏(lou)電(dian)保(bao)護繼(ji)電(dian)器(qi)會(hui)產(chan)生沖(chong)擊(ji)信號(hao)造成漏(lou)電(dian)保(bao)護器(qi)誤(wu)動(dong)。
3，光(guang)商工(gong)漏(lou)電(dian)保(bao)護繼(ji)電(dian)器(qi)多(duo)分(fen)支(zhi)漏(lou)電(dian)之和(he)可(ke)以(yi)造成越(yue)級(ji)誤(wu)動(dong)。
4，光(guang)商工(gong)漏(lou)電(dian)保(bao)護繼(ji)電(dian)器(qi)中(zhong)性(xing)線(xian)重(zhong)復(fu)接(jie)地可(ke)能造成串流誤(wu)動(dong)。
