斷路器和空開一樣嗎

斷路器按其使用(yong)范圍分為高(gao)壓(ya)(ya)斷(duan)路(lu)器(qi)和低(di)壓(ya)(ya)斷(duan)路(lu)器(qi)，高(gao)低(di)壓(ya)(ya)界線劃分比較(jiao)模(mo)糊，一(yi)(yi)般將3kV以(yi)上的(de)(de)(de)稱為高(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)器(qi)。 低(di)壓(ya)(ya)斷(duan)路(lu)器(qi)又稱自(zi)(zi)動(dong)(dong)(dong)開(kai)關，俗稱”空氣開(kai)關”也是(shi)指低(di)壓(ya)(ya)斷(duan)路(lu)器(qi)，它是(shi)一(yi)(yi)種既有手動(dong)(dong)(dong)開(kai)關作(zuo)用(yong)，又能(neng)(neng)自(zi)(zi)動(dong)(dong)(dong)進(jin)行(xing)失壓(ya)(ya)、欠壓(ya)(ya)、過載(zai)、和短路(lu)保護的(de)(de)(de)電(dian)(dian)(dian)(dian)器(qi)。它可用(yong)來分配電(dian)(dian)(dian)(dian)能(neng)(neng)，不(bu)頻繁地(di)啟動(dong)(dong)(dong)異(yi)步電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機，對電(dian)(dian)(dian)(dian)源(yuan)線路(lu)及電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機等(deng)實行(xing)保護，當它們發(fa)生嚴重的(de)(de)(de)過載(zai)或(huo)者短路(lu)及欠壓(ya)(ya)等(deng)故障時能(neng)(neng)自(zi)(zi)動(dong)(dong)(dong)切斷(duan)電(dian)(dian)(dian)(dian)路(lu)，其功能(neng)(neng)相(xiang)當于熔斷(duan)器(qi)式開(kai)關與過欠熱繼電(dian)(dian)(dian)(dian)器(qi)等(deng)的(de)(de)(de)組合(he)。而且在(zai)分斷(duan)故障電(dian)(dian)(dian)(dian)流后(hou)一(yi)(yi)般不(bu)需要(yao)變(bian)更零部件，已獲得了廣泛的(de)(de)(de)應用(yong)。

空氣開關又(you)名空氣斷(duan)(duan)(duan)路(lu)(lu)器，是(shi)斷(duan)(duan)(duan)路(lu)(lu)器的(de)(de)一種(zhong)。是(shi)一種(zhong)只要電(dian)(dian)路(lu)(lu)中電(dian)(dian)流超過額(e)定電(dian)(dian)流就會自動(dong)斷(duan)(duan)(duan)開的(de)(de)開關(guan)。空氣開關(guan)是(shi)低壓配電(dian)(dian)網絡和電(dian)(dian)力拖動(dong)系統中非(fei)常重要的(de)(de)一種(zhong)電(dian)(dian)器，它集控制和多種(zhong)保護功能(neng)(neng)于(yu)一身。除(chu)能(neng)(neng)完成接觸和分(fen)斷(duan)(duan)(duan)電(dian)(dian)路(lu)(lu)外，尚能(neng)(neng)對電(dian)(dian)路(lu)(lu)或電(dian)(dian)氣設備發生的(de)(de)短路(lu)(lu)、嚴重過載及欠電(dian)(dian)壓等進(jin)行保護，同(tong)時也可(ke)以(yi)用于(yu)不頻繁地啟動(dong)電(dian)(dian)動(dong)機。

斷路器和空氣開關的區別

空氣開關是(shi)斷路器(qi)的(de)一(yi)種，那么斷路器和空開怎么區分？斷(duan)路器和空氣開(kai)關有什么區別？

1、電壓等級的區別

一般(ban)空氣(qi)開(kai)關(guan)適用的電壓等級為500V以下，而斷路(lu)器通常可(ke)以適用于220V以上的各電壓等級。

2、遮斷電流的能力區別

一般斷路器能承受的負荷及短路電流更大(da)些(xie)。

3、滅弧介質和方式的區別

斷(duan)(duan)路(lu)器(qi)(qi)的滅弧介質和(he)方式(shi)不但有(you)空(kong)氣斷(duan)(duan)路(lu)器(qi)(qi)，還有(you)真(zhen)空(kong)斷(duan)(duan)路(lu)器(qi)(qi)，多(duo)油斷(duan)(duan)路(lu)器(qi)(qi)，少油斷(duan)(duan)路(lu)器(qi)(qi)，六氟(fu)化硫斷(duan)(duan)路(lu)器(qi)(qi)等。

4、配套設備的區別

一般相對于空開來講斷路器的測量、邏輯及執行部分的機構所配套(tao)的設備更復雜一(yi)些。

5、作用的區別

空氣開關一般(ban)在(zai)(zai)小(xiao)電(dian)(dian)流電(dian)(dian)路(lu)(lu)(lu)(lu)中主(zhu)要(yao)起“隔離”和“保護裝置”的(de)作(zuo)用(yong)；斷路(lu)(lu)(lu)(lu)器在(zai)(zai)電(dian)(dian)路(lu)(lu)(lu)(lu)短路(lu)(lu)(lu)(lu)大電(dian)(dian)流情況下，自(zi)動跳閘(zha)，在(zai)(zai)高電(dian)(dian)壓、電(dian)(dian)子產品世界大電(dian)(dian)流電(dian)(dian)路(lu)(lu)(lu)(lu)中，常用(yong)作(zuo)停(ting)電(dian)(dian)、送電(dian)(dian)，接通、斷開負荷的(de)操作(zuo)電(dian)(dian)器。
