故障的原因是什么？高壓配電柜的故(gu)障可能與它所(suo)包含的交流(liu)接觸(chu)器有關。型號和規(gui)格可能不(bu)(bu)正確。交流(liu)觸(chu)頭(tou)用于高(gao)壓(ya)配電柜(ju)的不(bu)(bu)同電路中，并(bing)(bing)且接觸(chu)器的電容(rong)(rong)也不(bu)(bu)同。如(ru)果連(lian)接不(bu)(bu)正確，接觸(chu)器很容(rong)(rong)易燒(shao)壞。它還受(shou)(shou)在(zai)某(mou)些高(gao)溫，低溫和潮(chao)濕(shi)環境中運行的環境溫度因素的影(ying)響，并(bing)(bing)且某(mou)些高(gao)壓(ya)配電柜(ju)放置在(zai)室外。由于高(gao)溫的長期影(ying)響，這些因素會產生高(gao)壓(ya)，并(bing)(bing)且配電柜(ju)中的設備溫度會升高(gao)，從而(er)使高(gao)壓(ya)配電柜(ju)的組件難以承受(shou)(shou)并(bing)(bing)導(dao)致過(guo)熱。

高壓配電柜通常用于生產和生活的各個領域，例如B.在學校，機構，醫院，工廠，車間，公寓等中，而專業的通常(chang)用于建(jian)筑工地，例如(ru)建(jian)筑工地。接線(xian)(xian)盒的尺寸很(hen)多，價格相差很(hen)大，而室內接線(xian)(xian)盒通常(chang)很(hen)小。購買時(shi)，您需要考慮幾個因素來選擇合(he)適(shi)的產品。高壓(ya)配電柜通常(chang)在接線(xian)(xian)盒中(zhong)有一個通用斷路(lu)(lu)器(qi)(qi)，該(gai)斷路(lu)(lu)器(qi)(qi)可管理整(zheng)個接線(xian)(xian)盒中(zhong)的所有斷路(lu)(lu)器(qi)(qi)以及(ji)接線(xian)(xian)端子。這在每個配電箱中(zhong)都(dou)是必不可少的，并(bing)根(gen)據信號數量進(jin)行配置。 ;繼電器(qi)(qi)的功能是PLC可以將(jiang)命令直接發(fa)送(song)到控制回(hui)路(lu)(lu)，但也可以先(xian)將(jiang)命令發(fa)送(song)到繼電器(qi)(qi)，然后(hou)再將(jiang)繼電器(qi)(qi)發(fa)送(song)到控制回(hui)路(lu)(lu)。

接(jie)線盒(he)中的(de)(de)熔(rong)化(hua)器是(shi)(shi)一(yi)種(zhong)電(dian)(dian)(dian)(dian)氣(qi)設備，它利用自身(shen)的(de)(de)熱量熔(rong)化(hua)熔(rong)體，當電(dian)(dian)(dian)(dian)流超過規(gui)定值時會產生熔(rong)化(hua)的(de)(de)熔(rong)體，并斷(duan)開電(dian)(dian)(dian)(dian)路。電(dian)(dian)(dian)(dian)流保(bao)護基于(yu)此原理。它是(shi)(shi)一(yi)種(zhong)常(chang)用的(de)(de)保(bao)護，必不可少的(de)(de)電(dian)(dian)(dian)(dian)表(biao)之一(yi)。電(dian)(dian)(dian)(dian)表(biao)分為三類(lei)。電(dian)(dian)(dian)(dian)流表(biao)主要(yao)測量電(dian)(dian)(dian)(dian)路中的(de)(de)電(dian)(dian)(dian)(dian)流，電(dian)(dian)(dian)(dian)壓(ya)表(biao)是(shi)(shi)測量電(dian)(dian)(dian)(dian)壓(ya)的(de)(de)儀(yi)器，電(dian)(dian)(dian)(dian)能表(biao)是(shi)(shi)測量電(dian)(dian)(dian)(dian)能的(de)(de)儀(yi)器。每個人的(de)(de)角色是(shi)(shi)不同的(de)(de)。
