斷路器的組成部分：輔助觸頭：與斷路器主電路分、合機(jī)構(gòu)機(jī)械上連動(dòng)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(guò)斷路器的分合，對(duì)其相關(guān)電器實(shí)施控制或聯(lián)鎖。例如向信號(hào)燈、繼電器等輸出信號(hào)。塑殼斷路器殼架等級(jí)額定電流100A為單斷點(diǎn)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(jí)額定電流400A及以上可裝兩常開(kāi)、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(bào)警觸頭：用于斷路器***的報(bào)警觸頭，并且此觸頭只有當(dāng)斷路器脫扣分?jǐn)嗪蟛艅?dòng)作，主要用于斷路器的負(fù)載出現(xiàn)過(guò)載短路或欠電壓等故障時(shí)而自由脫扣，報(bào)警觸頭從原來(lái)的常開(kāi)位置轉(zhuǎn)換成閉合位置，接通輔助線(xiàn)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(fù)載故障而自由脫扣的機(jī)率不太多，所以報(bào)警觸頭的壽命是斷路器壽命的十分之一。報(bào)警觸頭的工作電流通常不會(huì)超過(guò)1A。 </p> <p> <br /> </p> <p> <br /> </p><p> “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(hù)內(nèi)配電裝置，可供工礦企業(yè)、發(fā)電廠(chǎng)、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(wú)油化、少檢修及頻繁操作的使用場(chǎng)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。

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(chǎng)克服反力彈簧，脫扣器拉動(dòng)操作機(jī)構(gòu)動(dòng)作，開(kāi)關(guān)瞬時(shí)跳閘。當(dāng)過(guò)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(kāi)斷1500V，電流為1500-2000A的電弧，這些電弧可拉長(zhǎng)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(wèn)題。
