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(lái)，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(jī)構(gòu)。50年代末，因?yàn)殡娮釉呐d起，又產(chǎn)生了電子脫扣器，到了***，因?yàn)閱纹瑱C(jī)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(jìn)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(jìn)步又是由于真空技術(shù)、滅弧室技術(shù)的發(fā)展及運(yùn)用新工藝、新材料及新操動(dòng)技術(shù)的成果。這種技術(shù)除了可以作為傳統(tǒng)電機(jī)技術(shù)的替代技術(shù)以外，還將為直流電機(jī)拓展更為廣闊的發(fā)展和應(yīng)用空間。如開發(fā)大容量直流電機(jī)代替高壓直流輸電網(wǎng)供電的交流同步發(fā)電機(jī)和換流站設(shè)備，不但能夠節(jié)省大量換流站的建設(shè)費(fèi)用，還能夠大幅度降低變電損耗。 </p> <p> <br /> </p> <p> <br /> </p><p> 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、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(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1A。
