style="text-indent:25px">了解戶外真空高壓斷路器的人應(yīng)該知道它的參數(shù)以及機(jī)械性能對(duì)于它來說是比較為主要的，但是真空的斷路器有幾個(gè)很重要的機(jī)械性能往往不被重視。而這些機(jī)械性的往往決定了一個(gè)真空的斷路器的好壞與否。許多人不明白開距的作用。其實(shí)開距能夠決定一臺(tái)真空斷路器的耐壓性能。另外就是接觸電壓，接觸電壓能夠保證我們的兩個(gè)觸頭能夠很好的碰觸，保證工作。同時(shí)，也能夠幫助真空斷路器穩(wěn)定他的電壓。接觸行程也是十分重要的參數(shù)。這個(gè)參數(shù)其實(shí)就是一個(gè)壓縮的距離。這個(gè)壓縮的距離起到兩個(gè)的作用。一個(gè)就是為我們的觸頭工作的時(shí)候提供足夠的電壓，另外一個(gè)就是能夠在斷路器磨損了的時(shí)候給予保護(hù)距離，從而保護(hù)斷路器。而這個(gè)接觸行程的設(shè)計(jì)要十分巧妙。</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)帶來了很大的方便，增加了可靠性。斷路器有哪些方面是我們需要知道的？</p><div

斷路器通常由觸頭系統(tǒng)、滅弧系統(tǒng)、操作機(jī)構(gòu)、脫扣器、外殼等組成。當(dāng)短路時(shí)，大電流（一般10至12倍）產(chǎn)生的磁場克服反力彈簧，脫扣器拉動(dòng)操作機(jī)構(gòu)動(dòng)作，開關(guān)瞬時(shí)跳閘。當(dāng)過載時(shí)，電流變大，發(fā)熱量加劇，雙金屬片變形到一定程度推動(dòng)機(jī)構(gòu)動(dòng)作（電流越大，動(dòng)作時(shí)間越短）。有電子型的，運(yùn)用互感器采集各相電流大小，與設(shè)定值比較，當(dāng)電流異常時(shí)微處理器發(fā)出信號(hào)，使電子脫扣器帶動(dòng)操作機(jī)構(gòu)動(dòng)作。斷路器的作用是切斷和接通負(fù)荷電路，以及切斷故障電路，避免***擴(kuò)大，保證可靠運(yùn)行。而高壓斷路器要開斷1500V，電流為1500-2000A的電弧，這些電弧可拉長至2m仍然繼續(xù)燃燒不熄滅。故滅弧是高壓斷路器許需要解決的問題。
