LED顯示(shi)屏頻繁跳(tiao)閘究竟原(yuan)因何在，遇(yu)到顯示(shi)屏跳(tiao)閘該怎么辦？在這里小編和大家一起來探討(tao)一下。

    一、漏(lou)電(dian)保(bao)(bao)護(hu)器(qi)布局不(bu)(bu)合理引起的跳閘。由于全彩LED顯示屏安裝現場(chang)所具有的特殊(shu)性(xing)，如接線錯誤、線路破損(sun)(sun)、開關箱(xiang)內漏(lou)電(dian)保(bao)(bao)護(hu)器(qi)損(sun)(sun)壞、部分用電(dian)器(qi)具沒有經過(guo)開關箱(xiang)等原因，以(yi)及漏(lou)電(dian)保(bao)(bao)護(hu)器(qi)本身不(bu)(bu)可避免的誤動和拒動，再加上沒有按照實際用電(dian)情況對(dui)漏(lou)電(dian)保(bao)(bao)護(hu)器(qi)進行布置，造成了(le)總漏(lou)電(dian)保(bao)(bao)護(hu)器(qi)頻(pin)繁跳閘。

      二(er)、LED顯(xian)示屏(ping)在保(bao)(bao)(bao)護(hu)(hu)(hu)(hu)范圍內(nei)沒有(you)形(xing)成有(you)效(xiao)(xiao)的(de)(de)二(er)級或三(san)級漏(lou)電(dian)(dian)(dian)保(bao)(bao)(bao)護(hu)(hu)(hu)(hu)。開關箱內(nei)的(de)(de)末(mo)級漏(lou)電(dian)(dian)(dian)保(bao)(bao)(bao)護(hu)(hu)(hu)(hu)器(qi)(qi)是(shi)用電(dian)(dian)(dian)設備的(de)(de)主保(bao)(bao)(bao)護(hu)(hu)(hu)(hu)，如(ru)果末(mo)級漏(lou)電(dian)(dian)(dian)保(bao)(bao)(bao)護(hu)(hu)(hu)(hu)器(qi)(qi)不(bu)(bu)裝(zhuang)(zhuang)、損壞或選型(xing)不(bu)(bu)當(dang)，將可(ke)能導致(zhi)上級漏(lou)電(dian)(dian)(dian)保(bao)(bao)(bao)護(hu)(hu)(hu)(hu)器(qi)(qi)頻繁(fan)跳閘。由于(yu)全彩LED顯(xian)示屏(ping)內(nei)金屬導體很多(duo)，電(dian)(dian)(dian)線(xian)接頭較(jiao)多(duo)，如(ru)果導線(xian)絕緣不(bu)(bu)是(shi)很好，就(jiu)會導致(zhi)經(jing)常(chang)漏(lou)電(dian)(dian)(dian)的(de)(de)狀況;有(you)的(de)(de)還(huan)加了一些插座(zuo)，在很多(duo)時候都不(bu)(bu)裝(zhuang)(zhuang)漏(lou)電(dian)(dian)(dian)保(bao)(bao)(bao)護(hu)(hu)(hu)(hu)器(qi)(qi)，經(jing)常(chang)造成漏(lou)電(dian)(dian)(dian)。只有(you)在每 個保(bao)(bao)(bao)護(hu)(hu)(hu)(hu)范圍內(nei)形(xing)成有(you)效(xiao)(xiao)的(de)(de)二(er)級或三(san)級漏(lou)電(dian)(dian)(dian)保(bao)(bao)(bao)護(hu)(hu)(hu)(hu)模式(shi)，才能有(you)效(xiao)(xiao)地減少漏(lou)電(dian)(dian)(dian)保(bao)(bao)(bao)護(hu)(hu)(hu)(hu)器(qi)(qi)的(de)(de)頻繁(fan)跳閘。

    三(san)(san)、LED顯(xian)示屏(ping)的(de)(de)漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)保(bao)護(hu)(hu)器(qi)(qi)(qi)本身有(you)一(yi)定的(de)(de)局(ju)限性。目前的(de)(de)漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)保(bao)護(hu)(hu)器(qi)(qi)(qi)，不(bu)論是電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)型還(huan)是電(dian)(dian)(dian)(dian)(dian)子型均采用(yong)磁(ci)(ci)感應電(dian)(dian)(dian)(dian)(dian)壓互(hu)感器(qi)(qi)(qi)拾取用(yong)電(dian)(dian)(dian)(dian)(dian)設備 主(zhu)回路中(zhong)的(de)(de)漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)流(liu)，三(san)(san)相(xiang)或(huo)(huo)三(san)(san)相(xiang)四線在(zai)(zai)(zai)磁(ci)(ci)環(huan)(huan)中(zhong)不(bu)可能布(bu)置完(wan)全均衡(heng)。 全彩(cai)LED顯(xian)示屏(ping)的(de)(de)三(san)(san)相(xiang)用(yong)電(dian)(dian)(dian)(dian)(dian)負荷也不(bu)可能完(wan)全平衡(heng)，在(zai)(zai)(zai)大(da)(da)(da)電(dian)(dian)(dian)(dian)(dian)流(liu)下(xia)或(huo)(huo)較高的(de)(de)過電(dian)(dian)(dian)(dian)(dian)壓下(xia)，會在(zai)(zai)(zai)有(you)很高導磁(ci)(ci)率的(de)(de)磁(ci)(ci)環(huan)(huan)中(zhong)感應出一(yi)定的(de)(de)電(dian)(dian)(dian)(dian)(dian)動勢(shi)，這個電(dian)(dian)(dian)(dian)(dian)動勢(shi)大(da)(da)(da)到一(yi)定程度， 就會導致漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)保(bao)護(hu)(hu)器(qi)(qi)(qi)跳(tiao)閘(zha)。由于額定電(dian)(dian)(dian)(dian)(dian)流(liu)越大(da)(da)(da)的(de)(de)漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)保(bao)護(hu)(hu)器(qi)(qi)(qi)采用(yong)相(xiang)對(dui)較大(da)(da)(da)的(de)(de)磁(ci)(ci)環(huan)(huan)，產生的(de)(de)漏(lou)(lou)磁(ci)(ci)通也相(xiang)對(dui)較大(da)(da)(da)，且漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)流(liu)要克服(fu)磁(ci)(ci)環(huan)(huan)本身的(de)(de)磁(ci)(ci)化力，導致實際使用(yong)的(de)(de)漏(lou)(lou) 電(dian)(dian)(dian)(dian)(dian)保(bao)護(hu)(hu)器(qi)(qi)(qi)額定電(dian)(dian)(dian)(dian)(dian)流(liu)越大(da)(da)(da)，靈敏度越低，拒(ju)動率也越大(da)(da)(da)。

    四、全彩LED顯示屏的(de)漏電(dian)(dian)保護器在(zai)額(e)定漏電(dian)(dian)動(dong)(dong)作電(dian)(dian)流和額(e)定漏電(dian)(dian)不(bu)動(dong)(dong)作電(dian)(dian)流之間(jian)有一(yi)段動(dong)(dong)作不(bu)確定區域，漏電(dian)(dian)保護器的(de)漏電(dian)(dian)流在(zai)此(ci)區域內波動(dong)(dong)時，可能導致漏電(dian)(dian)保護器無(wu)規(gui)律跳閘。

    LED顯示屏在經(jing)濟生活中的(de)(de)應用(yong)是很廣泛的(de)(de)，很多企(qi)業和政府(fu)部門以及事(shi)業單位機關都會(hui)用(yong)到。為了生產經(jing)營(ying)安全(quan)，LED顯示屏應用(yong)單位應該也(ye)必(bi)須(xu)具備必(bi)要的(de)(de)LED顯示屏故(gu)障的(de)(de)解決方法(fa)。
