</p> <p> <br /> </p> <p> <br /> </p><p> 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)度不僅與間隙的大小，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>
