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，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)瞬時跳閘。當(dāng)過載時，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> 真空斷路器毫無例外地運(yùn)用對接式接觸方式。動觸頭碰上靜觸頭之后就不能再前進(jìn)了，觸頭接觸壓力是由每極觸頭壓縮彈簧(有時稱作合閘緩沖彈簧)提供的。所謂接觸行程，就是開關(guān)觸頭碰觸開始，觸頭壓簧施力端繼續(xù)運(yùn)動至終結(jié)的距離，亦即觸頭彈簧的壓縮距離，故又稱壓縮行程。接觸行程有兩方面作用，一是令觸頭彈簧受壓而向?qū)佑|頭提供接觸壓力；二是保證在運(yùn)行磨損后仍然保持一定的接觸壓力，使之可靠接觸。通常接觸行程可取開距的百分之二十到三十左右，10kV的真空斷路器約為3～4mm。

欠電壓脫扣器是在它的端電壓降至某一規(guī)定范圍的時候，使斷路器有延時或無延時斷開的一種脫扣器，當(dāng)電源電壓下降（甚至緩慢下降）到額定工作電壓的百分之七十至百分之三十五范圍內(nèi)，欠電壓脫扣器應(yīng)運(yùn)作，欠電壓脫扣器在電源電壓等于脫扣器額定工作電壓的百分之三十五時，欠電壓脫扣器應(yīng)能防止斷路器閉合；電源電壓等于或大于百分之八十五欠電壓脫扣器的額定工作電壓時，在熱態(tài)條件下，應(yīng)能保證斷路器可靠閉合。所以當(dāng)受保護(hù)電路中電源電壓發(fā)生一定的電壓降時，能自動斷開斷路器切斷電源，使該斷路器以下的負(fù)載電器或電氣設(shè)備免受欠電壓的損壞。使用時，欠電壓脫扣器線圈接在斷路器電源側(cè)，欠電壓脫扣器通電后，斷路器才能合閘。

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，大電流（一般10至12倍）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)瞬時跳閘。當(dāng)過載時，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。
