3、抽屜式接線：斷路器的進(jìn)出抽屜是由搖桿順時針或逆時針轉(zhuǎn)動的，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，同時給操作與維護(hù)帶來了很大的方便，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。 </p> <p> 4.板前接線：這種是使用**普遍的極限方式，一般不需要特別說明。其是指在斷路器安裝于成套裝置（開關(guān)柜、配電柜等）時在安裝板前，即在斷路器基座的連接板上直接接電源線和負(fù)載線，用螺釘緊固的接線。 </p> <p> <br /> </p> <p> <br /> NZM塑殼斷路器NZMB2-M125空氣斷路器的內(nèi)部附件有哪些？</p><div

<p> 斷路器銘牌上的額定電壓是指斷路器主觸頭的額定電壓，是保證接觸器觸頭長期正常工作的電壓值。 </p> <p> (2)額定電流 </p> <p> 接觸器銘牌上的額定電流是指路器主觸頭的額定電流，是保證接觸器觸頭長期正常工作的電流值。 </p> <p> ⑶脫扣電流 </p> <p> 脫扣電流是使過電流脫扣器動作的電流設(shè)定值，當(dāng)電路短路或負(fù)載嚴(yán)重超載，負(fù)載電流大于脫扣電流時，斷路器主觸頭分?jǐn)唷?</p> <p> ⑷過載保護(hù)電流、時間曲線 </p> <p> 過載保護(hù)電流、時間曲線，為反時限特性曲線，過載電流越大，熱脫扣器動作的時間就越短。 </p> <p> <br /> </p> <p> <br />

斷路器是用于合斷電源，同時具有瞬時過電流保護(hù)及延時過電流保護(hù)（有些品種還具有欠電壓保護(hù)）的開關(guān)元件。其瞬時過電流保護(hù)又被稱為短路保護(hù)；延時過電流保護(hù)又被稱為過載或過熱保護(hù)。這種開關(guān)又常被稱為“空氣開關(guān)”。 </p> <p> 較常用的斷路器為塑料殼式，現(xiàn)用的國產(chǎn)品種型號為DZ10和DZ**Z5型在較小電流的場合還有應(yīng)用。均具有瞬時過電流保護(hù)（或稱為短路保護(hù)）及延時過電流保護(hù)（或稱為過載保護(hù)），圖4-6為DZ5和DZ20型的外形圖，DZ10和DZ20型的結(jié)構(gòu)如圖4-7～圖4-9所示。一般的品種，要調(diào)節(jié)過電流保護(hù)值，須將其蓋打開方可進(jìn)行。
