世界上較早的斷路器產(chǎn)生于1885年，它是一種刀開頭和過電流脫扣器的組合。1905年，具有自由脫扣裝置的空氣斷路器誕生。1930年以來，隨著科技的發(fā)展，電弧原理的發(fā)現(xiàn)和各種滅弧裝置的發(fā)明，逐漸形成了機構(gòu)。50年代末，因為電子元件的興起，又產(chǎn)生了電子脫扣器，到了***，因為單片機的普及又有了智能型斷路器的出現(xiàn)。真空斷路器技術(shù)的發(fā)展，真空斷路器技術(shù)的進步表現(xiàn)在大容量化、低過電壓化、智能化和小型化。而這一進步又是由于真空技術(shù)、滅弧室技術(shù)的發(fā)展及運用新工藝、新材料及新操動技術(shù)的成果。這種技術(shù)除了可以作為傳統(tǒng)電機技術(shù)的替代技術(shù)以外，還將為直流電機拓展更為廣闊的發(fā)展和應用空間。如開發(fā)大容量直流電機代替高壓直流輸電網(wǎng)供電的交流同步發(fā)電機和換流站設(shè)備，不但能夠節(jié)省大量換流站的建設(shè)費用，還能夠大幅度降低變電損耗。

斷路器的組成部分：輔助觸頭：與斷路器主電路分、合機構(gòu)機械上連動的觸頭，主要用于斷路器分、合狀態(tài)的顯示，接在斷路器的控制電路中通過斷路器的分合，對其相關(guān)電器實施控制或聯(lián)鎖。例如向信號燈、繼電器等輸出信號。塑殼斷路器殼架等級額定電流100A為單斷點轉(zhuǎn)換觸頭，225A及以上為橋式觸頭結(jié)構(gòu)，約定發(fā)熱電流為3A；殼架等級額定電流400A及以上可裝兩常開、兩常閉，約定發(fā)熱電流為6A。操作性能次數(shù)與斷路器的操作性能總次數(shù)相同。報警觸頭：用于斷路器***的報警觸頭，并且此觸頭只有當斷路器脫扣分斷后才動作，主要用于斷路器的負載出現(xiàn)過載短路或欠電壓等故障時而自由脫扣，報警觸頭從原來的常開位置轉(zhuǎn)換成閉合位置，接通輔助線路中的指示燈或電鈴、蜂鳴器等，顯示或提醒斷路器的故障脫扣狀態(tài)。由于斷路器發(fā)生因負載故障而自由脫扣的機率不太多，所以報警觸頭的壽命是斷路器壽命的十分之一。報警觸頭的工作電流通常不會超過1A。 </p> <p> <br /> </p> <p> <br /> </p><p style="text-indent:25px">低壓斷路器是用于交流電壓1200V，直流電壓1500V的電路中起通斷、控制或保護等作用的電器。低壓斷路器是電器工業(yè)的重要組成元素，在機械行業(yè)中是基礎(chǔ)配套件，在配電系統(tǒng)中低壓成套開關(guān)設(shè)備主要由各種低壓斷路器元件組成，低壓斷路器的功能及性能對低壓成套開關(guān)設(shè)備起著特別重要的作用。發(fā)電設(shè)備所發(fā)出電能的百分之八十以上是通過低壓斷路器分配使用的。每增加1萬kW發(fā)電設(shè)備，約需2萬件左右的各類低壓斷路器與之配套。在工業(yè)自動化系統(tǒng)中，也需要由低壓斷路器構(gòu)成的各種控制屏、控制臺、控制器等產(chǎn)品。斷路器該如何去維護它呢？</p><div

真空斷路器的特點：觸頭開距小，10KV真空斷路器的觸頭開距只有10mm左右，操作機構(gòu)的操作功就小，機械部分行程小，其機械壽命就長。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30-50次，額定電流開斷達5000次以上，噪音小適于頻繁操作。體積小、重量輕。適用于開斷容性負荷電流。由于其優(yōu)點很多，所以多應用于變電站中，目前型號主要有：ZN12-10型、ZN28A-10型、ZN65A-12型、ZN12A-12型、VS1型、ZN30型等。

真空斷路器的實際結(jié)構(gòu)中，觸頭合閘彈簧設(shè)計成即使處于分閘位置，也有相當?shù)念A壓縮量，有預壓力。這是為使合閘過程中，當動觸頭尚未碰到靜觸頭而發(fā)生預擊穿時，動觸頭有相當力量抵抗電動力，而不致于向后退縮；當觸頭碰接瞬間，接觸壓力陡然躍增至預壓力數(shù)值，防止合閘彈跳，足以抵抗電動斥力，并使接觸初始就有良好狀態(tài)；隨著接觸行程的前進，觸頭間的接觸壓力漸漸增大，接觸行程終結(jié)時，接觸壓力達到設(shè)計值。接觸行程不包括合閘彈簧的預壓縮量程，它實際上是合閘彈簧的第二次受壓行程。
