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

“真空斷路器”由于其滅弧介質(zhì)和滅弧后觸頭間隙的絕緣介質(zhì)都是高真空而得名；真空斷路器具有體積小、重量輕、適用于頻繁操作、滅弧不用檢修的特點，真空斷路器在配電網(wǎng)中應(yīng)用較為普遍。真空斷路器是3～10kV，50Hz三相交流系統(tǒng)中的戶內(nèi)配電裝置，可供工礦企業(yè)、發(fā)電廠、變電站中作為電器設(shè)備的保護和控制之用，特別適用于要求無油化、少檢修及頻繁操作的使用場所，斷路器可配置在中置柜、雙層柜以及固定柜中作為控制和保護高壓電氣設(shè)備用。

真空斷路器”的觸頭常采取對接式觸頭。由于一般的真空斷路器在分閘狀態(tài)下動靜觸頭的距離只有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作電弧的損傷也較小。真空斷路器的優(yōu)點之一是體積小，動靜觸頭要在一個***真空的空間內(nèi)動作，如果制作成其他的對接方式也會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，很可能是導(dǎo)電回路某一連接處接觸不良。在大電流運行時接觸不良處的局部溫升增高，嚴(yán)重時甚至引起惡性循環(huán)造成氧化燒損，對用于大電流運行的斷路器尤需加倍注意。
