真空斷路器”的觸頭常采取對(duì)接式觸頭。由于一般的真空斷路器在分閘狀態(tài)下動(dòng)靜觸頭的距離只有16mm這么小的距離很難制作出其他形狀的接觸面，而且平直的接觸面瞬間動(dòng)作電弧的損傷也較小。真空斷路器的優(yōu)點(diǎn)之一是體積小，動(dòng)靜觸頭要在一個(gè)***真空的空間內(nèi)動(dòng)作，如果制作成其他的對(duì)接方式也會(huì)增加斷路器自身的體積！回路電阻值是表征導(dǎo)電回路的聯(lián)接是否良好的一個(gè)參數(shù)，各類型產(chǎn)品都規(guī)定了一定范圍內(nèi)的值。若回路電阻超過規(guī)定值時(shí)，很可能是導(dǎo)電回路某一連接處接觸不良。在大電流運(yùn)行時(shí)接觸不良處的局部溫升增高，嚴(yán)重時(shí)甚至引起惡性循環(huán)造成氧化燒損，對(duì)用于大電流運(yùn)行的斷路器尤需加倍注意。 </p> <p> <br /> </p> <p> <br /> </p><p> 欠電壓脫扣器是在它的端電壓降至某一規(guī)定范圍的時(shí)候，使斷路器有延時(shí)或無(wú)延時(shí)斷開的一種脫扣器，當(dāng)電源電壓下降（甚至緩慢下降）到額定工作電壓的百分之七十至百分之三十五范圍內(nèi)，欠電壓脫扣器應(yīng)運(yùn)作，欠電壓脫扣器在電源電壓等于脫扣器額定工作電壓的百分之三十五時(shí)，欠電壓脫扣器應(yīng)能防止斷路器閉合；電源電壓等于或大于百分之八十五欠電壓脫扣器的額定工作電壓時(shí)，在熱態(tài)條件下，應(yīng)能保證斷路器可靠閉合。所以當(dāng)受保護(hù)電路中電源電壓發(fā)生一定的電壓降時(shí)，能自動(dòng)斷開斷路器切斷電源，使該斷路器以下的負(fù)載電器或電氣設(shè)備免受欠電壓的損壞。使用時(shí)，欠電壓脫扣器線圈接在斷路器電源側(cè)，欠電壓脫扣器通電后，斷路器才能合閘。
