真空有著很強的絕緣特性，在真空斷路器中，氣體特別稀薄，氣體分子的自由行程相對較大，發(fā)生相互碰撞的幾率很小，因此，碰撞游離不是真空間隙擊穿的主要原因，而在**電場作用下由電極析出的金屬質(zhì)點才是引起絕緣破壞的主要因素。真空間隙中的絕緣強度不僅與間隙的大小，電場的均勻程度有關(guān)，而且受電極材料的性質(zhì)及表面狀況的影響較大。真空間隙在較小的距離間隙（ 2—3 毫米）條件下，有比高壓力空氣與SF6 氣體高的絕緣特性，這就是真空斷路器的觸頭開距一般不大的因素。電極材料對擊穿電壓的影響主要表現(xiàn)在材料的機械強度（抗拉強度）和金屬材料的熔點上?？估瓘姸群腿埸c越高，電極在真空下的絕緣強度越高。 </p> <p> <br /> </p> <p> <br /> </p><p> 世界上較早的斷路器產(chǎn)生于1885年，它是一種刀開頭和過電流脫扣器的組合。1905年，具有自由脫扣裝置的空氣斷路器誕生。1930年以來，隨著科技的發(fā)展，電弧原理的發(fā)現(xiàn)和各種滅弧裝置的發(fā)明，逐漸形成了機構(gòu)。50年代末，因為電子元件的興起，又產(chǎn)生了電子脫扣器，到了***，因為單片機的普及又有了智能型斷路器的出現(xiàn)。真空斷路器技術(shù)的發(fā)展，真空斷路器技術(shù)的進步表現(xiàn)在大容量化、低過電壓化、智能化和小型化。而這一進步又是由于真空技術(shù)、滅弧室技術(shù)的發(fā)展及運用新工藝、新材料及新操動技術(shù)的成果。這種技術(shù)除了可以作為傳統(tǒng)電機技術(shù)的替代技術(shù)以外，還將為直流電機拓展更為廣闊的發(fā)展和應(yīng)用空間。如開發(fā)大容量直流電機代替高壓直流輸電網(wǎng)供電的交流同步發(fā)電機和換流站設(shè)備，不但能夠節(jié)省大量換流站的建設(shè)費用，還能夠大幅度降低變電損耗。

斷路器的接線方式有板前、板后、插入式、抽屜式，用戶如無特殊要求，均按板前供貨，板前接線是比較常見的接線方式。插入式接線：在成套裝置的安裝板上，先安裝一個斷路器的安裝座，安裝座上六個插頭，斷路器的連接板上有六個插座。安裝座的面上有連接板或安裝座后有螺栓，安裝座預(yù)先接上電源線和負載線。運用時候，將斷路器直接**安裝座。若斷路器壞了，只要拔出壞的，換上一只好的即可。它的更換時間比板前，板后接線要短，且方便。因為插、拔需要一定的人力。所以國內(nèi)的插入式產(chǎn)品，其殼架電流限制在較大為400A。從而節(jié)省了維修和更換時間。插入式斷路器在安裝時應(yīng)檢查斷路器的插頭是否壓緊，并應(yīng)將斷路器緊固，來減少接觸電阻，提高可靠性。

斷路器通常由觸頭系統(tǒng)、滅弧系統(tǒng)、操作機構(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構(gòu)動作（電流越大，動作時間越短）。有電子型的，運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構(gòu)動作。斷路器的作用是切斷和接通負荷電路，以及切斷故障電路，避免***擴大，保證可靠運行。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。
