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(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。
