欠電壓脫扣器是在它的端電壓降至某一規(guī)定范圍的時(shí)候，使斷路器有延時(shí)或無延時(shí)斷開的一種脫扣器，當(dāng)電源電壓下降（甚至緩慢下降）到額定工作電壓的百分之七十至百分之三十五范圍內(nèi)，欠電壓脫扣器應(yīng)運(yùn)作，欠電壓脫扣器在電源電壓等于脫扣器額定工作電壓的百分之三十五時(shí)，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百分之八十五欠電壓脫扣器的額定工作電壓時(shí)，在熱態(tài)條件下，應(yīng)能保證斷路器可靠閉合。所以當(dāng)受保護(hù)電路中電源電壓發(fā)生一定的電壓降時(shí)，能自動(dòng)斷開斷路器切斷電源，使該斷路器以下的負(fù)載電器或電氣設(shè)備免受欠電壓的損壞。使用時(shí)，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。

真空斷路器的特點(diǎn)：觸頭開距小，10KV真空斷路器的觸頭開距只有10mm左右，操作機(jī)構(gòu)的操作功就小，機(jī)械部分行程小，其機(jī)械壽命就長(zhǎng)。燃弧時(shí)間短，且與開關(guān)電流大小無關(guān)，一般只有半周波。熄弧后觸頭間隙介質(zhì)恢復(fù)速度快，對(duì)開斷近區(qū)故障性能較好。由于觸頭在開斷電流時(shí)磨損量較小，所以觸頭的電氣壽命長(zhǎng)，滿容量開斷達(dá)30-50次，額定電流開斷達(dá)5000次以上，噪音小適于頻繁操作。體積小、重量輕。適用于開斷容性負(fù)荷電流。由于其優(yōu)點(diǎn)很多，所以多應(yīng)用于變電站中，目前型號(hào)主要有：ZN12-10型、ZN28A-10型、ZN65A-12型、ZN12A-12型、VS1型、ZN30型等。

斷路器是一種基本的低壓電器，斷路器具有過載、短路和欠電壓保護(hù)功能，有保護(hù)線路和電源的能力。主要技術(shù)指標(biāo)是額定電壓、額定電流。斷路器按照不一樣的應(yīng)用具有不同有著不一樣的功能，品種、規(guī)格很多，具體的技術(shù)指標(biāo)也有許多。斷路器自由脫扣：斷路器在合閘過程中的任何時(shí)刻，若是保護(hù)動(dòng)作接通跳閘回路，斷路器完全能可靠地?cái)嚅_，這就叫自由脫扣。帶有自由脫扣的斷路器，能夠保證斷路器合閘短路故障時(shí)，可以迅速斷開，可以防止擴(kuò)大***的范圍。
