斷路器和空開一樣嗎

斷路器按其使用范圍分為高壓(ya)(ya)(ya)斷路(lu)(lu)(lu)器和(he)低壓(ya)(ya)(ya)斷路(lu)(lu)(lu)器，高低壓(ya)(ya)(ya)界線劃分比較模糊，一般將3kV以上的稱為高壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)器。 低壓(ya)(ya)(ya)斷路(lu)(lu)(lu)器又稱自(zi)(zi)動(dong)開關(guan)，俗稱”空氣開關(guan)”也是指低壓(ya)(ya)(ya)斷路(lu)(lu)(lu)器，它是一種既(ji)有(you)手動(dong)開關(guan)作用，又能自(zi)(zi)動(dong)進行失(shi)壓(ya)(ya)(ya)、欠壓(ya)(ya)(ya)、過(guo)載(zai)、和(he)短(duan)路(lu)(lu)(lu)保(bao)護的電(dian)(dian)(dian)(dian)器。它可用來分配電(dian)(dian)(dian)(dian)能，不頻繁地啟(qi)動(dong)異步電(dian)(dian)(dian)(dian)動(dong)機(ji)，對電(dian)(dian)(dian)(dian)源線路(lu)(lu)(lu)及電(dian)(dian)(dian)(dian)動(dong)機(ji)等(deng)實行保(bao)護，當它們發生嚴(yan)重(zhong)的過(guo)載(zai)或者短(duan)路(lu)(lu)(lu)及欠壓(ya)(ya)(ya)等(deng)故障(zhang)時能自(zi)(zi)動(dong)切斷電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)，其功能相當于熔斷器式開關(guan)與過(guo)欠熱繼電(dian)(dian)(dian)(dian)器等(deng)的組(zu)合。而且(qie)在分斷故障(zhang)電(dian)(dian)(dian)(dian)流后一般不需要變更(geng)零部件，已獲得(de)了廣泛的應用。

空氣開關又名空(kong)氣(qi)斷(duan)(duan)路器，是(shi)斷(duan)(duan)路器的一(yi)(yi)種(zhong)。是(shi)一(yi)(yi)種(zhong)只要(yao)電(dian)(dian)(dian)路中(zhong)電(dian)(dian)(dian)流超過額定電(dian)(dian)(dian)流就會自動斷(duan)(duan)開(kai)(kai)的開(kai)(kai)關。空(kong)氣(qi)開(kai)(kai)關是(shi)低(di)壓(ya)(ya)配電(dian)(dian)(dian)網絡和(he)電(dian)(dian)(dian)力(li)拖動系統中(zhong)非常(chang)重要(yao)的一(yi)(yi)種(zhong)電(dian)(dian)(dian)器，它集控制和(he)多種(zhong)保護功(gong)能于一(yi)(yi)身。除能完成接(jie)觸和(he)分斷(duan)(duan)電(dian)(dian)(dian)路外，尚能對電(dian)(dian)(dian)路或電(dian)(dian)(dian)氣(qi)設備發生的短路、嚴重過載及(ji)欠電(dian)(dian)(dian)壓(ya)(ya)等進(jin)行保護，同時(shi)也可以用于不頻(pin)繁地(di)啟動電(dian)(dian)(dian)動機(ji)。

斷路器和空氣開關的區別

空(kong)氣開關是斷路器(qi)的一種(zhong)，那么斷路器和空開怎么區分？斷路(lu)器和空(kong)氣開關有什么區別？

1、電壓等級的區別

一般(ban)空氣開關(guan)適(shi)用的(de)(de)電壓等級為500V以(yi)下，而斷路器(qi)通常可以(yi)適(shi)用于220V以(yi)上的(de)(de)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(liu)更大些。

3、滅弧介質和方式的區別

斷(duan)路(lu)器的滅(mie)弧介質和(he)方(fang)式不但(dan)有(you)空氣斷(duan)路(lu)器，還有(you)真空斷(duan)路(lu)器，多油斷(duan)路(lu)器，少油斷(duan)路(lu)器，六氟化(hua)硫斷(duan)路(lu)器等。

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(ji)及執行部分(fen)的機構(gou)所配套的設備更(geng)復雜一些(xie)。

5、作用的區別

空(kong)氣開(kai)關一般在(zai)小電(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)路中主要起(qi)“隔離(li)”和“保護裝(zhuang)置”的作(zuo)用；斷路器在(zai)電(dian)(dian)(dian)路短路大電(dian)(dian)(dian)流(liu)(liu)情況下，自(zi)動(dong)跳閘，在(zai)高電(dian)(dian)(dian)壓、電(dian)(dian)(dian)子產品(pin)世(shi)界大電(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)路中，常用作(zuo)停(ting)電(dian)(dian)(dian)、送電(dian)(dian)(dian)，接通、斷開(kai)負荷的操作(zuo)電(dian)(dian)(dian)器。
