斷路器通常由觸頭系統(tǒng)、滅弧系統(tǒng)、操作機構(gòu)、脫扣器、外殼等組成。當短路時，大電流（一般10至12倍）產(chǎn)生的磁場克服反力彈簧，脫扣器拉動操作機構(gòu)動作，開關(guān)瞬時跳閘。當過載時，電流變大，發(fā)熱量加劇，雙金屬片變形到一定程度推動機構(gòu)動作（電流越大，動作時間越短）。有電子型的，運用互感器采集各相電流大小，與設(shè)定值比較，當電流異常時微處理器發(fā)出信號，使電子脫扣器帶動操作機構(gòu)動作。斷路器的作用是切斷和接通負荷電路，以及切斷故障電路，避免***擴大，保證可靠運行。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。

style="text-indent:25px">斷路器是一種基本的低壓電器，斷路器具有過載、短路和欠電壓保護功能，有保護線路和電源的能力。主要技術(shù)指標是額定電壓、額定電流，斷路器按照不一樣的應(yīng)用具有不同有著不一樣的功能，品種、規(guī)格很多，具體的技術(shù)指標也有許多。斷路器自由脫扣：斷路器在合閘過程中的任何時刻，若是保護動作接通跳閘回路，斷路器完全能可靠地斷開，這就叫自由脫扣。帶有自由脫扣的斷路器，能夠保證斷路器合閘短路故障時，可以迅速斷開，可以防止擴大***的范圍。</p><p style="text-indent:25px">斷路器的分閘速度一般而言速度越快越好，這樣可以使首開相在電流趨近于0前2～3ms時能開斷故障電流；否則首開相不能開斷而延續(xù)至下一相，原來首開相變?yōu)楹箝_相，燃弧時間加長了，增加了開斷的難度，甚至使開斷失敗。但分閘速度太快，分閘的反彈也大，反彈太大震動過劇亦容易產(chǎn)生重燃，所以分間速度亦應(yīng)考慮這方面原因。分閘速度的快慢，主要決定于合閘時動觸頭彈簧和分閘彈簧的貯能大小。為了提**閘速度，可以增加分閘彈簧的貯能量，也能夠增加合閘彈簧的壓縮量，這都必然需要提高操動機構(gòu)的輸出功和整機的機械強度，降低了技術(shù)經(jīng)濟指標。通過多年試驗認為，10kV的真空斷路器，平均分閘速度能保證在0.95～1.2m/s比較合適。斷路器維護應(yīng)該注意哪些方面？</p><div

style="text-indent:25px">真空斷路器的閉鎖包括：機械閉鎖是開關(guān)設(shè)備操作機構(gòu)的機械結(jié)構(gòu)相互制約，從而達到相互聯(lián)鎖的閉鎖方式。電磁閉鎖是利用斷路器、隔離開關(guān)、斷路器柜門等的輔助接點，接通或斷開需閉鎖的隔離開關(guān)、開關(guān)柜門等電磁鎖電源，使其操作機構(gòu)無法動作，從而實現(xiàn)開關(guān)設(shè)備之間的相互閉鎖。這種閉鎖裝置原理簡單，實現(xiàn)便捷，非同一體的開關(guān)設(shè)備之間就可實現(xiàn)閉鎖;它在干燥的環(huán)境運行比較可*。但受一些情況所限，大多安裝在35千伏及以下室內(nèi)設(shè)備上。在使用中，由于輔助轉(zhuǎn)換開關(guān)種種原因不能正常切換，和電磁鎖不能滿足密封要求而受潮銹蝕，使閉鎖常常失靈。對室外高壓開關(guān)設(shè)備要實現(xiàn)防誤閉鎖大多運用電氣邏輯閉鎖。斷路器該怎么選擇購買？金華斷路器訂購</p><p

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。
