斷路器通常由觸頭系統(tǒng)、滅弧系統(tǒng)、操作機(jī)構(gòu)、脫扣器、外殼等組成。當(dāng)短路時(shí)，大電流產(chǎn)生的磁場克服反力彈簧，脫扣器拉動操作機(jī)構(gòu)動作，開關(guān)瞬時(shí)跳閘。當(dāng)過載時(shí)，電流變大，發(fā)熱量加劇，雙金屬片變形到一定程度推動機(jī)構(gòu)動作（電流越大，動作時(shí)間越短）。有電子型的，運(yùn)用互感器采集各相電流大小，與設(shè)定值比較，當(dāng)電流異常時(shí)微處理器發(fā)出信號，使電子脫扣器帶動操作機(jī)構(gòu)動作。斷路器的作用是切斷和接通負(fù)荷電路，以及切斷故障電路，避免***擴(kuò)大，保證可靠運(yùn)行。而高壓斷路器要開斷1500V，電流為1500-2000A的電弧，這些電弧可拉長至2m仍然繼續(xù)燃燒不熄滅。故滅弧是高壓斷路器許需要解決的問題。 </p> <p> <br /> </p> <p> <br /> </p><p> 真空斷路器通常是用在高壓部分，而塑殼斷路器則是用在低壓這部分。高壓真空斷路器和塑殼斷路器的分?jǐn)嗄芰Σ煌?，分?jǐn)喾绞揭膊煌?。高壓真空斷路器在真空管?nèi)實(shí)現(xiàn)分?jǐn)?，所產(chǎn)生的電弧在真空管里很快熄滅而不會產(chǎn)生大的危害；塑殼斷路器（又稱空氣開關(guān)）可直接暴露在空氣中分?jǐn)?，電弧小，只需要在塑殼斷路器的接線端裝相間隔板就行了。在短路開斷能力，真空斷路器有很強(qiáng)的短路開斷能力，塑殼斷路器通常只是進(jìn)行額定電流的開斷，如果短路也是需要借助外接的熔斷器來進(jìn)行開斷。
