真空有著很強(qiáng)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(duì)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(chǎng)作用下由電極析出的金屬質(zhì)點(diǎn)才是引起絕緣破壞的主要因素。真空間隙中的絕緣強(qiáng)度不*與間隙的大小，電場(chǎng)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(kāi)距一般不大的因素。電極材料對(duì)擊穿電壓的影響主要表現(xiàn)在材料的機(jī)械強(qiáng)度（抗拉強(qiáng)度）和金屬材料的熔點(diǎn)上。抗拉強(qiáng)度和熔點(diǎn)越高，電極在真空下的絕緣強(qiáng)度越高。 </p> <p> <br /> </p>

style="text-indent:25px">斷路器的主要組成構(gòu)造是什么？杭州戶(hù)外真空斷路器</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(shí)，大電流產(chǎn)生的磁場(chǎng)克服反力彈簧，脫扣器拉動(dòng)操作機(jī)構(gòu)動(dòng)作，開(kāi)關(guān)瞬時(shí)跳閘。當(dāng)過(guò)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(dòng)機(jī)構(gòu)動(dòng)作（電流越大，動(dòng)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(hào)，使電子脫扣器帶動(dòng)操作機(jī)構(gòu)動(dòng)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(kāi)斷1500V，電流為1500-2000A的電弧，這些電弧可拉長(zhǎng)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(wèn)題。
