真空斷路器毫無(wú)例外地運(yùn)用對(duì)接式接觸方式。動(dòng)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(shí)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(dòng)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 style="text-indent:25px">真空斷路器處于分閘狀態(tài)時(shí)，真空開關(guān)管動(dòng)、靜觸頭之間的距離選擇與真空斷路器的額定電壓、使用條件、開斷電流的性質(zhì)及觸頭材料、真空間隙的耐壓強(qiáng)度等因素有關(guān)，主要取決于額定電壓和觸頭材料。因?yàn)檎婵臻_關(guān)管的額定開距對(duì)絕緣性能的影響較大，當(dāng)額定開距從零開距增大時(shí)，其絕緣水平也將提高，但當(dāng)開距增大到一定數(shù)值時(shí)，開距對(duì)絕緣性能的影響就不大了，若進(jìn)一步增大開距，將嚴(yán)重影響開關(guān)管的機(jī)械壽命。通過對(duì)戶外高壓真空斷路器的安裝、運(yùn)行及檢修得出真空斷路器額定開距通常選擇范圍為：6kV及以下一般為4～8mm，10kV及以下一般為8～12mm，35kV一般為20～40mm。斷路器有哪些不同的分類？</p><div
