“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(diǎn)，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(hù)和控制之用，特別適用于要求無(wú)油化、少檢修及頻繁操作的使用場(chǎng)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(hù)高壓電氣設(shè)備用。 </p> <p> <br /> </p> <p> <br /> </p><p style="text-indent:25px">板前、板后、插入式、抽屜式是斷路器的接線方式，用戶假如無(wú)特殊要求，均按板前供貨，板前接線是常見的接線方式。板后接線方式：板后接線較大特點(diǎn)是能夠在更換或維修斷路器，不必重新接線，只須將前級(jí)電源斷開。由于該結(jié)構(gòu)特殊，產(chǎn)品出廠時(shí)已按設(shè)計(jì)要求配置了**安裝板和安裝螺釘及接線螺釘，需要很注意的是因?yàn)榇笕萘繑嗦菲鹘佑|的可靠性將直接影響斷路器的正常使用，所以安裝時(shí)需要引起重視，嚴(yán)格按制造廠要求進(jìn)行安裝。抽屜式接線：斷路器的進(jìn)出抽屜是由搖桿順時(shí)針或逆時(shí)針轉(zhuǎn)動(dòng)的，在主回路和二次回路中均采用了插入式結(jié)構(gòu)，省略了固定式所需要的隔離器，做到一機(jī)二用，提高了使用的經(jīng)濟(jì)性，同時(shí)給操作與維護(hù)帶來(lái)了很大的方便，增加了可靠性。關(guān)于真空斷路器的知識(shí)你了解多少？</p><div

真空有著很強(qiáng)的絕緣特性，在真空斷路器中，氣體特別稀薄，氣體分子的自由行程相對(duì)較大，發(fā)生相互碰撞的幾率很小，因此，碰撞游離不是真空間隙擊穿的主要原因，而在**電場(chǎng)作用下由電極析出的金屬質(zhì)點(diǎn)才是引起絕緣破壞的主要因素。真空間隙中的絕緣強(qiáng)度不僅與間隙的大小，電場(chǎng)的均勻程度有關(guān)，而且受電極材料的性質(zhì)及表面狀況的影響較大。真空間隙在較小的距離間隙（ 2—3 毫米）條件下，有比高壓力空氣與SF6 氣體高的絕緣特性，這就是真空斷路器的觸頭開距一般不大的因素。電極材料對(duì)擊穿電壓的影響主要表現(xiàn)在材料的機(jī)械強(qiáng)度（抗拉強(qiáng)度）和金屬材料的熔點(diǎn)上?？估瓘?qiáng)度和熔點(diǎn)越高，電極在真空下的絕緣強(qiáng)度越高。 </p> <p> <br /> </p> <p>
