斷路器和空開一樣嗎

斷路器按其(qi)使用范(fan)圍分為高(gao)(gao)壓斷(duan)(duan)(duan)(duan)(duan)路器(qi)(qi)和(he)低(di)壓斷(duan)(duan)(duan)(duan)(duan)路器(qi)(qi)，高(gao)(gao)低(di)壓界線劃分比(bi)較(jiao)模糊，一般將(jiang)3kV以上的稱(cheng)為高(gao)(gao)壓電器(qi)(qi)。 低(di)壓斷(duan)(duan)(duan)(duan)(duan)路器(qi)(qi)又(you)稱(cheng)自(zi)動(dong)開(kai)(kai)關，俗稱(cheng)”空氣開(kai)(kai)關”也是指(zhi)低(di)壓斷(duan)(duan)(duan)(duan)(duan)路器(qi)(qi)，它(ta)是一種既(ji)有手(shou)動(dong)開(kai)(kai)關作用，又(you)能(neng)(neng)自(zi)動(dong)進行失壓、欠(qian)壓、過(guo)載、和(he)短路保護(hu)的電器(qi)(qi)。它(ta)可用來分配(pei)電能(neng)(neng)，不頻繁地(di)啟動(dong)異步電動(dong)機，對電源線路及(ji)電動(dong)機等實(shi)行保護(hu)，當它(ta)們發生嚴重的過(guo)載或者(zhe)短路及(ji)欠(qian)壓等故障時能(neng)(neng)自(zi)動(dong)切斷(duan)(duan)(duan)(duan)(duan)電路，其(qi)功能(neng)(neng)相當于(yu)熔(rong)斷(duan)(duan)(duan)(duan)(duan)器(qi)(qi)式開(kai)(kai)關與過(guo)欠(qian)熱繼電器(qi)(qi)等的組(zu)合。而且在分斷(duan)(duan)(duan)(duan)(duan)故障電流后一般不需要變更零部(bu)件，已獲得(de)了廣泛(fan)的應用。

空氣開關又名空氣斷(duan)路(lu)(lu)器，是斷(duan)路(lu)(lu)器的一種(zhong)。是一種(zhong)只要(yao)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)中電(dian)(dian)(dian)(dian)(dian)流(liu)超過額定電(dian)(dian)(dian)(dian)(dian)流(liu)就會自動(dong)斷(duan)開(kai)(kai)的開(kai)(kai)關。空氣開(kai)(kai)關是低(di)壓配電(dian)(dian)(dian)(dian)(dian)網絡和(he)(he)電(dian)(dian)(dian)(dian)(dian)力拖動(dong)系統中非常重要(yao)的一種(zhong)電(dian)(dian)(dian)(dian)(dian)器，它集控制和(he)(he)多(duo)種(zhong)保(bao)護功(gong)能于(yu)(yu)一身。除能完(wan)成接觸和(he)(he)分斷(duan)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)外，尚(shang)能對電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)或電(dian)(dian)(dian)(dian)(dian)氣設(she)備發生(sheng)的短(duan)路(lu)(lu)、嚴(yan)重過載及欠電(dian)(dian)(dian)(dian)(dian)壓等進行保(bao)護，同時(shi)也(ye)可(ke)以用于(yu)(yu)不頻(pin)繁地啟(qi)動(dong)電(dian)(dian)(dian)(dian)(dian)動(dong)機。

斷路器和空氣開關的區別

空氣(qi)開關是斷(duan)路器的一種，那么斷路器和空開怎么區分？斷路(lu)器和(he)空氣(qi)開關有什么區別？

1、電壓等級的區別

一般空(kong)氣開(kai)關適用的電壓(ya)等級(ji)為500V以(yi)下(xia)，而斷路器通常可以(yi)適用于220V以(yi)上(shang)的各(ge)電壓(ya)等級(ji)。

2、遮斷電流的能力區別

一般斷路(lu)器能承(cheng)受的負荷及短(duan)路(lu)電(dian)流(liu)更大些。

3、滅弧介質和方式的區別

斷(duan)路(lu)(lu)(lu)(lu)器(qi)(qi)的滅弧介質和方式不但有空氣斷(duan)路(lu)(lu)(lu)(lu)器(qi)(qi)，還(huan)有真空斷(duan)路(lu)(lu)(lu)(lu)器(qi)(qi)，多油(you)斷(duan)路(lu)(lu)(lu)(lu)器(qi)(qi)，少(shao)油(you)斷(duan)路(lu)(lu)(lu)(lu)器(qi)(qi)，六氟化硫斷(duan)路(lu)(lu)(lu)(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(ce)量、邏輯及執行(xing)部分的機(ji)構所配套的設備(bei)更復雜一些。

5、作用的區別

空氣開關一般在小電(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)路(lu)中(zhong)主要起“隔離”和“保護裝置”的作用；斷路(lu)器(qi)在電(dian)(dian)(dian)(dian)路(lu)短路(lu)大電(dian)(dian)(dian)(dian)流(liu)(liu)情況下，自動跳閘，在高電(dian)(dian)(dian)(dian)壓、電(dian)(dian)(dian)(dian)子產品(pin)世界大電(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)路(lu)中(zhong)，常用作停電(dian)(dian)(dian)(dian)、送(song)電(dian)(dian)(dian)(dian)，接通、斷開負荷的操作電(dian)(dian)(dian)(dian)器(qi)。
