<br /> </p> <p> <br /> </p> <p> <strong>塑殼斷路器</strong>的接線方式（三） </p> <p> 3、抽屜式接線：斷路器的進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，做到一機二用，提高了使用的經(jīng)濟性，同時給操作與維護帶來了很大的方便，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載線，用螺釘緊固的接線。 </p> <p> <br /> </p> <p> <br /> NZM塑殼斷路器NZMN1-4-A100塑殼斷路器上的數(shù)字型號表示的什么意思？</p><div

欠電壓脫扣器：欠電壓脫扣器是在它的端電壓降至某一規(guī)定范圍時，使斷路器有延時或無延時斷開的一種脫扣器，當(dāng)電源電壓下降(甚至緩慢下降)到額定工作電壓的70%至35%范圍內(nèi)，欠電壓脫扣器應(yīng)運作，欠電壓脫扣器在電源電壓等于脫扣器額定工作電壓的35%時，欠電壓脫扣器應(yīng)能防止斷路器閉合；電源電壓等于或大于85%欠電壓脫扣器的額定工作電壓時，在熱態(tài)條件下，應(yīng)能保證斷路器可靠閉合。因此，當(dāng)受保護電路中電源電壓發(fā)生一定的電壓降時，能自動斷開斷路器切斷電源，使該斷路器以下的負載電器或電氣設(shè)備免受欠電壓的損壞。使用時，欠電壓脫扣器線圈接在斷路器電源側(cè)，欠電壓脫扣器通電后，斷路器才能合閘，否則斷路器合不上閘。
