        斷路器接線方式

        2013/12/16 8:19:01      點(diǎn)擊:

        斷路器的接線方式有板前、板后、插入式、抽屜式,用戶如無(wú)特殊要求,

        斷路器
        均按板前供貨,板前接線是常見的接線方式。
        1、板后接線方式:板后接線最大特點(diǎn)是可以在更換或維修斷路器,不必重新接線,只須將前級(jí)電源斷開。由于該結(jié)構(gòu)特殊,產(chǎn)品出廠時(shí)已按設(shè)計(jì)要求配置了專用安裝板和安裝螺釘及接線螺釘,需要特別注意的是由于大容量斷路器接觸的可靠性將直接影響斷路器的正常使用,因此安裝時(shí)必須引起重視,嚴(yán)格按制造廠要求進(jìn)行安裝。
        2、插入式接線:在成套裝置的安裝板上,先安裝一個(gè)斷路器的安裝座,安裝座上6個(gè)插頭,斷路器的連接板上有6個(gè)插座。安裝座的面上有連接板或安裝座后有螺栓,安裝座預(yù)先接上電源線和負(fù)載線。使用時(shí),將斷路器直接插進(jìn)安裝座。如果斷路器壞了,只要拔出壞的,換上一只好的即可。它的更換時(shí)間比板前,板后接線要短,且方便。由于插、拔需要一定的人力。因此中國(guó)的插入式產(chǎn)品,其殼架電流限制在最大為400A。從而節(jié)省了維修和更換時(shí)間。插入式斷路器在安裝時(shí)應(yīng)檢查斷路器的插頭是否壓緊,并應(yīng)將斷路器安全緊固,以減少接觸電阻,提高可靠性。
        3、抽屜式接線:斷路器的進(jìn)出抽屜是由搖桿順時(shí)針或逆時(shí)針轉(zhuǎn)動(dòng)的,在主回路和二次回路中均采用了
        插入式結(jié)構(gòu),省略了固定式所必須的隔離器,做到一機(jī)二用,提高了使用的經(jīng)濟(jì)性,同時(shí)給操作與維護(hù)帶來(lái)了很大的方便,增加了安全性、可靠性。特別是抽屜座的主回路觸刀座,可與NT型熔斷路器觸刀座通用,這樣在應(yīng)急狀態(tài)下可直接插入熔斷器供電。
