“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(hù)高壓電氣設(shè)備用。

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，只須將前級電源斷開。由于該結(jié)構(gòu)特殊，產(chǎn)品出廠時已按設(shè)計要求配置了**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針或逆時針轉(zhuǎn)動的，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，同時給操作與維護(hù)帶來了很大的方便，增加了可靠性。購買斷路器需要注意哪些方面？南充斷路器廠家</p><p style="text-indent:25px">選擇斷路器時，我們應(yīng)該先了解哪些方面？溫州真空斷路器選型</p><p 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。溫州真空斷路器選型</p><p
