數控(kong)母排加工(gong)機漏(lou)電斷路器在(zai)使(shi)用中(zhong)展現重(zhong)要的操作貢獻(xian),嚴格按照一定的使(shi)用原理和方(fang)式進行控(kong)制和使(shi)用,在(zai)保護裝置中(zhong)產生重(zhong)要的貢獻(xian)和價值,但是在(zai)使(shi)用中(zhong)可能會產生拒動作與誤動作,需要按照實(shi)際的情況和標(biao)準進行使(shi)用漏(lou)電斷路器的拒動作主要原因有(you):

　由于電(dian)(dian)(dian)路(lu)(lu)安裝(zhuang)人(ren)員把PE線(xian)和N線(xian)接反,將引起(qi)誤(wu)(wu)(wu)動(dong)(dong)(dong)作(zuo);在(zai)照明與動(dong)(dong)(dong)力合(he)用的(de)(de)(de)三相四線(xian)制電(dian)(dian)(dian)路(lu)(lu)中,錯誤(wu)(wu)(wu)的(de)(de)(de)選用了三極漏(lou)(lou)電(dian)(dian)(dian)斷路(lu)(lu)器(qi)(qi),負載的(de)(de)(de)零線(xian)直接在(zai)保(bao)護器(qi)(qi)的(de)(de)(de)電(dian)(dian)(dian)源側而(er)引起(qi)誤(wu)(wu)(wu)動(dong)(dong)(dong)作(zuo);母線(xian)機漏(lou)(lou)電(dian)(dian)(dian)保(bao)護器(qi)(qi)附近有(you)大(da)功率(lv)電(dian)(dian)(dian)器(qi)(qi),當(dang)電(dian)(dian)(dian)器(qi)(qi)開合(he)時(shi)產生(sheng)電(dian)(dian)(dian)磁干擾(rao)會(hui)引起(qi)誤(wu)(wu)(wu)動(dong)(dong)(dong)作(zuo);經過(guo)(guo)三相漏(lou)(lou)電(dian)(dian)(dian)保(bao)護器(qi)(qi)的(de)(de)(de)三相電(dian)(dian)(dian)源線(xian)未按照同一方(fang)向(xiang)通(tong)過(guo)(guo)零序互(hu)感器(qi)(qi),導致誤(wu)(wu)(wu)動(dong)(dong)(dong)作(zuo);在(zai)安裝(zhuang)使用時(shi),由于漏(lou)(lou)電(dian)(dian)(dian)斷路(lu)(lu)器(qi)(qi)靈敏度(du)選擇過(guo)(guo)高,也將誤(wu)(wu)(wu)動(dong)(dong)(dong)作(zuo).漏(lou)(lou)電(dian)(dian)(dian)斷路(lu)(lu)器(qi)(qi)相線(xian)與零線(xian)的(de)(de)(de)絕緣電(dian)(dian)(dian)阻(zu)太低,部(bu)分電(dian)(dian)(dian)流(liu)經漏(lou)(lou)電(dian)(dian)(dian)處(chu)泄(xie)露(lu)大(da)地(di),使電(dian)(dian)(dian)路(lu)(lu)正常時(shi)通(tong)過(guo)(guo)零序電(dian)(dian)(dian)流(liu)互(hu)感器(qi)(qi)的(de)(de)(de)電(dian)(dian)(dian)流(liu)矢量(liang)和不為零而(er)引起(qi)誤(wu)(wu)(wu)動(dong)(dong)(dong)作(zuo);用電(dian)(dian)(dian)設備外(wai)殼的(de)(de)(de)PE線(xian)與工作(zuo)中性線(xian)相連(lian)時(shi),引起(qi)誤(wu)(wu)(wu)動(dong)(dong)(dong)作(zuo).

在日常的(de)運用中,要讓數控(kong)母排加工機(ji)(ji)(ji)電(dian)(dian)(dian)動機(ji)(ji)(ji)講清(qing)潔(jie).電(dian)(dian)(dian)動機(ji)(ji)(ji)在作業中,若有(you)塵(chen)埃(ai)、水漬(zi)和其(qi)它雜(za)(za)(za)物(wu)進(jin)入了(le)(le)其(qi)內(nei)里,會構成短路前言,可破壞導線絕緣層,致(zhi)使匝(za)間(jian)短路,電(dian)(dian)(dian)流增大,溫度升高(gao)而燃燒消滅(mie)電(dian)(dian)(dian)動機(ji)(ji)(ji).由于這個,應防止塵(chen)埃(ai)、水漬(zi)和其(qi)它雜(za)(za)(za)物(wu)進(jin)入了(le)(le)電(dian)(dian)(dian)動機(ji)(ji)(ji)內(nei)里,一起還要常常給(gei)電(dian)(dian)(dian)動機(ji)(ji)(ji)的(de)外(wai)部(bu)整理清(qing)潔(jie),不要讓電(dian)(dian)(dian)動機(ji)(ji)(ji)的(de)散(san)(san)熱筋內(nei)有(you)塵(chen)埃(ai)和其(qi)他雜(za)(za)(za)物(wu),保證(zheng)電(dian)(dian)(dian)動機(ji)(ji)(ji)的(de)散(san)(san)熱情況令人滿(man)意.

　　電器柜定期清除積塵，保持(chi)清潔，可用吹氣(qi)或擦(ca)除方法(fa)。隨時注意并保證各(ge)連(lian)接件的(de)固(gu)定螺(luo)釘鎖緊，各(ge)組件的(de)連(lian)接端子(zi)是否(fou)鎖緊，以防(fang)止(zhi)接觸不良，產生誤動作或故障(zhang)。確保電纜的(de)彎曲(qu)度，以防(fang)電線(xian)折斷。
