漏電保護開關

A.漏電保護開關概念：

既具備漏(lou)電(dian)(dian)(dian)(dian)保護(hu)(hu)功(gong)能，人(ren)觸摸到(dao)帶(dai)電(dian)(dian)(dian)(dian)體會(hui)跳(tiao)閘，確保人(ren)身安全(quan)，是漏(lou)電(dian)(dian)(dian)(dian)保護(hu)(hu)器(qi)的(de)主(zhu)要功(gong)能；用(yong)電(dian)(dian)(dian)(dian)設備如果絕緣不好漏(lou)電(dian)(dian)(dian)(dian)到(dao)外殼上，漏(lou)電(dian)(dian)(dian)(dian)保護(hu)(hu)器(qi)也(ye)會(hui)跳(tiao)閘，避免人(ren)體觸摸觸電(dian)(dian)(dian)(dian)。同時具備電(dian)(dian)(dian)(dian)流通(tong)斷功(gong)能、過負荷保護(hu)(hu)和短路保護(hu)(hu)功(gong)能。

B. 漏電保護開關(guan)的工作原理(li)：

漏(lou)電(dian)保護器(qi)的(de)工作原理圖(tu)。圖(tu)中(zhong)LH為(wei)(wei)零(ling)序電(dian)流互感(gan)器(qi)，它(ta)由坡莫合(he)金(jin)為(wei)(wei)材料的(de)鐵(tie)(tie)芯，和繞在環(huan)狀鐵(tie)(tie)芯上的(de)二次線圈(quan)組成(cheng)檢(jian)測元件。電(dian)源(yuan)相線和中(zhong)性線穿(chuan)過圓(yuan)孔成(cheng)為(wei)(wei)零(ling)序互感(gan)器(qi)的(de)一次線圈(quan)。互感(gan)器(qi)的(de)后部出線即為(wei)(wei)保護范(fan)圍。

C.漏電(dian)保護(hu)開關的作用:

1、當電氣設備或線路發(fa)生漏電或接地故(gu)障時，能在人尚(shang)未觸(chu)及之前就把(ba)電源(yuan)切斷。2、當人體(ti)(ti)觸(chu)及帶電的物體(ti)(ti)時，能在011s內切斷電源(yuan)，從而減輕電流對人體(ti)(ti)的傷害程度。3、可以防止(zhi)因(yin)漏電而引起的火災事故(gu)。

3．雙電源自動轉(zhuan)換開關(guan)：

A.雙電源自動轉換(huan)開關的概念:

雙(shuang)(shuang)(shuang)電(dian)(dian)(dian)源(yuan)自動(dong)轉換(huan)開關(guan)為(wei)電(dian)(dian)(dian)源(yuan)二(er)選一(yi)(yi)自動(dong)切換(huan)系統，第(di)一(yi)(yi)路(lu)(lu)出現故障后(hou)雙(shuang)(shuang)(shuang)電(dian)(dian)(dian)源(yuan)自動(dong)轉換(huan)開關(guan)自動(dong)切換(huan)到(dao)第(di)二(er)路(lu)(lu)給(gei)負載供電(dian)(dian)(dian)，第(di)二(er)路(lu)(lu)故障的話雙(shuang)(shuang)(shuang)電(dian)(dian)(dian)源(yuan)自動(dong)轉換(huan)開關(guan)自動(dong)切換(huan)到(dao)第(di)一(yi)(yi)路(lu)(lu)給(gei)負載供電(dian)(dian)(dian)。 適合用于UPS-UPS，UPS-發電(dian)(dian)(dian)機，UPS-市(shi)電(dian)(dian)(dian)，市(shi)電(dian)(dian)(dian)-市(shi)電(dian)(dian)(dian)等(deng)任(ren)意兩路(lu)(lu)電(dian)(dian)(dian)源(yuan)的不斷電(dian)(dian)(dian)轉換(huan)。
