為什么電梯了不能安裝漏電保護開關？ 首(shou)先要講(jiang)解一(yi)下漏電(dian)(dian)(dian)保護開關的原理： 漏電(dian)(dian)(dian)保護開關的動作(zuo)原理是：在一(yi)個(ge)(ge)鐵(tie)芯上(shang)有(you)兩個(ge)(ge)組(zu)：一(yi)個(ge)(ge)輸(shu)(shu)(shu)入電(dian)(dian)(dian)流(liu)繞(rao)(rao)(rao)組(zu)和一(yi)個(ge)(ge)輸(shu)(shu)(shu)出電(dian)(dian)(dian)流(liu)繞(rao)(rao)(rao)組(zu)，當無(wu)漏電(dian)(dian)(dian)時，輸(shu)(shu)(shu)入電(dian)(dian)(dian)流(liu)和輸(shu)(shu)(shu)出電(dian)(dian)(dian)流(liu)相(xiang)等(deng)，在鐵(tie)芯上(shang)二磁通的矢(shi)量(liang)和為(wei)零，就不會在第(di)三個(ge)(ge)繞(rao)(rao)(rao)組(zu)上(shang)感應(ying)出電(dian)(dian)(dian)...
低壓開關電器中電弧的產生和滅弧方法？ 電(dian)(dian)孤(gu)是(shi)一種氣體放(fang)電(dian)(dian)現象，它有兩個(ge)特(te)點：一是(shi)電(dian)(dian)弧中有大量的電(dian)(dian)子、離子，因(yin)而是(shi)導電(dian)(dian)的，電(dian)(dian)孤(gu)不熄(xi)滅電(dian)(dian)路繼續導通，要電(dian)(dian)弧熄(xi)滅后(hou)電(dian)(dian)路才正式斷開(kai);二是(shi)電(dian)(dian)弧的溫度(du)(du)很(hen)高，弧心溫度(du)(du)達4000～5000攝氏度(du)(du)以上(shang)，高溫電(dian)(dian)弧會(hui)燒(shao)壞(huai)設備造成嚴重...
空氣開關和漏電保護器該如何快速區分？ 1、漏(lou)電保護(hu)(hu)器有一個(ge)漏(lou)電試(shi)驗按鈕，空氣(qi)開關沒有。記得(de)按完后，部分品牌的(de)漏(lou)電保護(hu)(hu)器要復位(wei)后才能送(song)電。還有一個(ge)明顯的(de)漏(lou)電保護(hu)(hu)動作指示。 2、空氣(qi)開關是(shi)快速(su)分斷電源用的(de)，漏(lou)電保護(hu)(hu)器在快速(su)分斷電源的(de)同時，能在小電流漏(lou)電時...
開關插座銅片質量應該怎么鑒別？ 大(da)家在購(gou)買開關插(cha)(cha)座時，通常都希望(wang)買到一款壽命(ming)長，質(zhi)量好的產(chan)品(pin)。那么對于(yu)開關插(cha)(cha)座而言，其里(li)面(mian)的銅片(pian)好壞就(jiu)直(zhi)接決定了它的質(zhi)量，今天讓廣珠電氣(qi)給大(da)家說說究(jiu)竟怎(zen)樣識別開關插(cha)(cha)座銅皮(pi)的材(cai)質(zhi)。 1、材(cai)料： 銅片(pian)材(cai)料是決定銅片(pian)性...
