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(guò)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> 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。

合閘彈跳時(shí)間是斷路器在合閘時(shí)，觸頭剛接觸開始計(jì)起，隨后產(chǎn)生分離，可能又接觸又分離，到其穩(wěn)定接觸之間的時(shí)間。這一參數(shù)國(guó)外的標(biāo)準(zhǔn)中都沒(méi)有明確規(guī)定，1989年底能源部電力司提出真空斷路器合閘彈跳時(shí)間需要小于2ms。為什么合閘彈跳時(shí)間要小于2ms呢？主要是合閘彈跳的瞬間會(huì)引起電力系統(tǒng)或設(shè)備產(chǎn)生L.C高頻振蕩，振蕩產(chǎn)生的過(guò)電壓對(duì)電氣設(shè)備的絕緣可能造成傷害甚至損壞。當(dāng)合閘彈跳時(shí)；同小于2ms時(shí)，不會(huì)產(chǎn)生較大的過(guò)電壓，設(shè)備絕緣不會(huì)受損，在關(guān)合時(shí)動(dòng)靜觸頭之間也不會(huì)產(chǎn)生熔焊。
