數控母排加工機漏電斷路器(qi)在(zai)使(shi)(shi)用中(zhong)展現重要(yao)(yao)的(de)(de)操作(zuo)貢獻(xian),嚴格按(an)照(zhao)一定的(de)(de)使(shi)(shi)用原理和(he)方(fang)式進(jin)行(xing)控制(zhi)和(he)使(shi)(shi)用,在(zai)保護裝(zhuang)置中(zhong)產(chan)生(sheng)重要(yao)(yao)的(de)(de)貢獻(xian)和(he)價值(zhi),但是在(zai)使(shi)(shi)用中(zhong)可能會(hui)產(chan)生(sheng)拒動(dong)作(zuo)與誤動(dong)作(zuo),需(xu)要(yao)(yao)按(an)照(zhao)實(shi)際的(de)(de)情況和(he)標準進(jin)行(xing)使(shi)(shi)用漏電斷路器(qi)的(de)(de)拒動(dong)作(zuo)主要(yao)(yao)原因(yin)有:

　由于電(dian)(dian)(dian)(dian)(dian)路安裝人員(yuan)把(ba)PE線(xian)(xian)和(he)N線(xian)(xian)接反(fan),將(jiang)引(yin)起(qi)(qi)(qi)誤(wu)動(dong)作(zuo)(zuo)(zuo)(zuo);在(zai)照(zhao)明(ming)與(yu)動(dong)力合用(yong)的(de)(de)(de)三相(xiang)四線(xian)(xian)制電(dian)(dian)(dian)(dian)(dian)路中(zhong),錯誤(wu)的(de)(de)(de)選(xuan)用(yong)了三極漏(lou)電(dian)(dian)(dian)(dian)(dian)斷(duan)路器(qi)(qi)(qi)(qi),負(fu)載的(de)(de)(de)零(ling)線(xian)(xian)直(zhi)接在(zai)保護(hu)(hu)(hu)器(qi)(qi)(qi)(qi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源側而引(yin)起(qi)(qi)(qi)誤(wu)動(dong)作(zuo)(zuo)(zuo)(zuo);母線(xian)(xian)機漏(lou)電(dian)(dian)(dian)(dian)(dian)保護(hu)(hu)(hu)器(qi)(qi)(qi)(qi)附近有大(da)功率電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi),當電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)開合時產生電(dian)(dian)(dian)(dian)(dian)磁干(gan)擾會引(yin)起(qi)(qi)(qi)誤(wu)動(dong)作(zuo)(zuo)(zuo)(zuo);經(jing)過(guo)(guo)(guo)三相(xiang)漏(lou)電(dian)(dian)(dian)(dian)(dian)保護(hu)(hu)(hu)器(qi)(qi)(qi)(qi)的(de)(de)(de)三相(xiang)電(dian)(dian)(dian)(dian)(dian)源線(xian)(xian)未按(an)照(zhao)同(tong)一方(fang)向通(tong)過(guo)(guo)(guo)零(ling)序互感器(qi)(qi)(qi)(qi),導致誤(wu)動(dong)作(zuo)(zuo)(zuo)(zuo);在(zai)安裝使(shi)用(yong)時,由于漏(lou)電(dian)(dian)(dian)(dian)(dian)斷(duan)路器(qi)(qi)(qi)(qi)靈敏度選(xuan)擇(ze)過(guo)(guo)(guo)高,也將(jiang)誤(wu)動(dong)作(zuo)(zuo)(zuo)(zuo).漏(lou)電(dian)(dian)(dian)(dian)(dian)斷(duan)路器(qi)(qi)(qi)(qi)相(xiang)線(xian)(xian)與(yu)零(ling)線(xian)(xian)的(de)(de)(de)絕緣電(dian)(dian)(dian)(dian)(dian)阻太低,部分電(dian)(dian)(dian)(dian)(dian)流(liu)經(jing)漏(lou)電(dian)(dian)(dian)(dian)(dian)處泄露大(da)地(di),使(shi)電(dian)(dian)(dian)(dian)(dian)路正(zheng)常時通(tong)過(guo)(guo)(guo)零(ling)序電(dian)(dian)(dian)(dian)(dian)流(liu)互感器(qi)(qi)(qi)(qi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)矢量和(he)不為(wei)零(ling)而引(yin)起(qi)(qi)(qi)誤(wu)動(dong)作(zuo)(zuo)(zuo)(zuo);用(yong)電(dian)(dian)(dian)(dian)(dian)設備外殼(ke)的(de)(de)(de)PE線(xian)(xian)與(yu)工(gong)作(zuo)(zuo)(zuo)(zuo)中(zhong)性線(xian)(xian)相(xiang)連(lian)時,引(yin)起(qi)(qi)(qi)誤(wu)動(dong)作(zuo)(zuo)(zuo)(zuo).

在日常(chang)的運用中,要讓數(shu)控母排加工機(ji)電(dian)(dian)(dian)動機(ji)講清(qing)潔.電(dian)(dian)(dian)動機(ji)在作業中,若有塵埃、水漬和其它雜物(wu)進(jin)入(ru)(ru)了其內里(li)(li),會構(gou)成短(duan)路前言(yan),可破壞導線絕緣層,致(zhi)使匝間短(duan)路,電(dian)(dian)(dian)流增大,溫度升高而(er)燃(ran)燒消滅電(dian)(dian)(dian)動機(ji).由于這個(ge),應防(fang)止塵埃、水漬和其它雜物(wu)進(jin)入(ru)(ru)了電(dian)(dian)(dian)動機(ji)內里(li)(li),一起還要常(chang)常(chang)給電(dian)(dian)(dian)動機(ji)的外(wai)部整理清(qing)潔,不要讓電(dian)(dian)(dian)動機(ji)的散熱筋內有塵埃和其他雜物(wu),保證(zheng)電(dian)(dian)(dian)動機(ji)的散熱情況(kuang)令(ling)人滿意.

　　電器柜定期清除(chu)積塵，保持清潔，可用(yong)吹(chui)氣或(huo)擦除(chu)方(fang)法。隨(sui)時(shi)注意并保證(zheng)各連接(jie)件的(de)固定螺釘鎖(suo)緊(jin)，各組件的(de)連接(jie)端子是否鎖(suo)緊(jin)，以防止接(jie)觸(chu)不良，產生(sheng)誤動(dong)作或(huo)故障。確(que)保電纜的(de)彎曲度，以防電線折斷。
