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(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(shí)；同小于2ms時(shí)，不會(huì)產(chǎn)生較大的過電壓，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。

低壓斷路器是用于交流電壓1200V，直流電壓1500V的電路中起通斷、控制或保護(hù)等作用的電器。低壓斷路器是電器工業(yè)的重要組成元素，在機(jī)械行業(yè)中是基礎(chǔ)配套件，在配電系統(tǒng)中低壓成套開關(guān)設(shè)備主要由各種低壓斷路器元件組成，低壓斷路器的功能及性能對低壓成套開關(guān)設(shè)備起著特別重要的作用。發(fā)電設(shè)備所發(fā)出電能的百分之八十以上是通過低壓斷路器分配使用的。每增加1萬kW發(fā)電設(shè)備，約需2萬件左右的各類低壓斷路器與之配套。在工業(yè)自動(dòng)化系統(tǒng)中，也需要由低壓斷路器構(gòu)成的各種控制屏、控制臺(tái)、控制器等產(chǎn)品。國內(nèi)的低壓斷路器行業(yè)自1949年后，是在一些修理、裝配簡單電器工廠的基礎(chǔ)上逐步發(fā)展成能**設(shè)計(jì)、生產(chǎn)的行業(yè)，到1979共有生產(chǎn)企業(yè)600多家，經(jīng)過1985～1986年、1990～1991年兩個(gè)發(fā)展高峰，1995年低壓斷路器行業(yè)已有生產(chǎn)企業(yè)約1500家。 </p> <p> <br /> </p> <p> <br /> </p><p> 真空斷路器的實(shí)際結(jié)構(gòu)中，觸頭合閘彈簧設(shè)計(jì)成即使處于分閘位置，也有相當(dāng)?shù)念A(yù)壓縮量，有預(yù)壓力。這是為使合閘過程中，當(dāng)動(dòng)觸頭尚未碰到靜觸頭而發(fā)生預(yù)擊穿時(shí)，動(dòng)觸頭有相當(dāng)力量抵抗電動(dòng)力，而不致于向后退縮；當(dāng)觸頭碰接瞬間，接觸壓力陡然躍增至預(yù)壓力數(shù)值，防止合閘彈跳，足以抵抗電動(dòng)斥力，并使接觸初始就有良好狀態(tài)；隨著接觸行程的前進(jìn)，觸頭間的接觸壓力漸漸增大，接觸行程終結(jié)時(shí)，接觸壓力達(dá)到設(shè)計(jì)值，接觸行程不包括合閘彈簧的預(yù)壓縮量程，它實(shí)際上是合閘彈簧的第二次受壓行程。

style="text-indent:25px">真空斷路器的特點(diǎn)：觸頭開距小，10KV真空斷路器的觸頭開距只有10mm左右，操作機(jī)構(gòu)的操作功就小，機(jī)械部分行程小，其機(jī)械壽命就長。燃弧時(shí)間短，且與開關(guān)電流大小無關(guān)，一般只有半周波。熄弧后觸頭間隙介質(zhì)恢復(fù)速度快，對開斷近區(qū)故障性能較好。由于觸頭在開斷電流時(shí)磨損量較小，所以觸頭的電氣壽命長，滿容量開斷達(dá)30-50次，額定電流開斷達(dá)5000次以上，噪音小適于頻繁操作。體積小、重量輕。適用于開斷容性負(fù)荷電流。由于其優(yōu)點(diǎn)很多，所以多應(yīng)用于變電站中。購買斷路器需要注意哪些方面？南昌斷路器報(bào)價(jià)</p><p
