真空斷路器技術(shù)標(biāo)準(zhǔn)真空斷路器在我國近十年來取得了很好的發(fā)展。產(chǎn)品從過去的ZN1～ZN5幾個品種發(fā)展到數(shù)十多個型號、品種，額定電流達(dá)到5000A，開斷電流達(dá)到50kA的較好水平，并已發(fā)展到電壓達(dá)35kV等級真空斷路器的工作原理是：當(dāng)動、靜觸頭在操作機(jī)構(gòu)的作用下分閘時，觸頭間產(chǎn)生電弧，觸頭表面在高溫下?lián)]發(fā)出蒸汽，因為觸頭設(shè)計為特殊形狀，在電流通過時產(chǎn)生一磁場，電弧在此磁場作用下沿觸頭表面切線方向快速運(yùn)動，在金屬圓筒(屏蔽罩)上凝結(jié)了部分金屬蒸汽，電弧在自然過零時就熄滅了，觸頭間的介質(zhì)強(qiáng)度又快速的恢復(fù)起來。

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。 </p> <p> <br /> </p> <p> <br /> </p><p> 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。
