戶(hù)外真空斷路器為什么采用交流電?

文/ 發(fā)布于 2020/6/29    瀏覽次數:250

    戶(hù)高壓交流真空斷路器為什么采用的是交流的?那需要從我國的電力系統說(shuō)起,其實(shí)我們電力也有用直流電的地區。比如說(shuō)三陜水電站。

    那么我國電力系統一般用的是交流電,所以高壓真空斷路器也必須是交流真空斷路器,人類(lèi)歷早的輸電線(xiàn)路是直流的。開(kāi)始時(shí)輸電電壓只有100V,后來(lái)逐步提高,到1885年提高到6kV。但是,制造高電壓、大功率的直流發(fā)電機很困難,又不能直接給直流升壓,而遠距離輸電需要高電壓。這限制了直流輸電的發(fā)展。另一方面,19世紀80年代末發(fā)明了三相交流發(fā)電機和變壓器,特別是發(fā)明了結構簡(jiǎn)單、運行可靠、價(jià)格便宜的感應電動(dòng)機,交流的應用范圍進(jìn)一步擴大。與這種情況相適應,交流輸電獲得了長(cháng)足發(fā)展。
    看了上面的介紹相信大家都明白戶(hù)外真空斷路器采用交流電的原因了吧!若您還有更多的戶(hù)外真空斷路器問(wèn)題,可以多多關(guān)注雷爾沃電器官網(wǎng)http://www.lazeezcaters.com/,或與我們聯(lián)系,雷爾沃將及時(shí)為您解決問(wèn)題。
