斷路器通常由觸頭系統(tǒng)、滅弧系統(tǒng)、操作機構、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動作，開關瞬時跳閘。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。 </p> <p> <br /> </p> <p> <br /> </p><p> 分勵脫扣器是一種用電壓源激勵的脫扣器，它的電壓與主電路電壓無關。分勵脫扣器是一種遠距離操縱分閘的附件。當電源電壓等于額定控制電源電壓的百分之七十到百分之一百一十之間的任一電壓時，就能可靠性的分斷斷路器。分勵脫扣器是短時工作制，線圈通電時間一般不能超過1S，不然線就會被燒毀。塑殼斷路器為避免線圈燒毀，在分勵脫扣線圈串聯(lián)一個微動開關，當分勵脫扣器通過銜鐵吸合，微動開關從常閉狀態(tài)轉換成常開，由于分勵脫扣器電源的控制線路被切斷，即使人為的按住按鈕，分勵線圈始終不會再通電這就避免了線圈燒損情況的產(chǎn)生。當斷路器再扣合閘后，微動開關重新處于常閉位置。

真空斷路器技術標準真空斷路器在我國近十年來取得了很好的發(fā)展。產(chǎn)品從過去的ZN1～ZN5幾個品種發(fā)展到數(shù)十多個型號、品種，額定電流達到5000A，開斷電流達到50kA的較好水平，并已發(fā)展到電壓達35kV等級真空斷路器的工作原理是：當動、靜觸頭在操作機構的作用下分閘時，觸頭間產(chǎn)生電弧，觸頭表面在高溫下?lián)]發(fā)出蒸汽，因為觸頭設計為特殊形狀，在電流通過時產(chǎn)生一磁場，電弧在此磁場作用下沿觸頭表面切線方向快速運動，在金屬圓筒(屏蔽罩)上凝結了部分金屬蒸汽，電弧在自然過零時就熄滅了，觸頭間的介質強度又快速的恢復起來。

真空斷路器的部件中觸頭結構大致有三種：圓柱形觸頭、帶有螺旋槽跑弧面的橫向磁場觸頭、縱向磁場觸頭。目前采用縱磁場技術，此種滅弧室具有強而穩(wěn)定的電弧開斷能力。屏蔽系統(tǒng)，屏蔽罩是真空滅弧室中不可缺少的元件，并且有圍繞觸頭的主屏蔽罩、波紋管屏蔽罩和均壓用屏蔽罩等多種。主屏蔽罩的作用是：防止燃弧過程中電弧生成物噴濺到絕緣外殼的內壁，從而降低外殼的絕緣強度。改善滅弧室內部電場分布的均勻性，有利于降低局部場強，促進真空滅弧室小型化。冷凝電弧生成物，吸收一部分電弧能量，有助于弧后間隙介質強度的恢復。
