空氣斷路器，又名空氣開(kāi)關(guān)，是斷路器的一種。是一種只要電路中電流超過(guò)額定電流就會(huì)自動(dòng)斷開(kāi)的開(kāi)關(guān)?？諝忾_(kāi)關(guān)是低壓配電網(wǎng)絡(luò)和電力拖動(dòng)系統(tǒng)中非常重要的一種電器，它集控制和多種保護(hù)功能于一身。除能完成接觸和分?jǐn)嚯娐吠?，尚能?duì)電路或電氣設(shè)備發(fā)生的短路、嚴(yán)重過(guò)載及欠電壓等進(jìn)行保護(hù)，同時(shí)也可以用于不頻繁地啟動(dòng)電動(dòng)機(jī)。 </p> <p> 空氣斷路器的主要作用 </p> <p> 在正常情況下，過(guò)電流脫扣器的銜鐵是釋放著的；一旦發(fā)生嚴(yán)重過(guò)載或短路故障時(shí)，與主電路串聯(lián)的線(xiàn)圈就將產(chǎn)生較強(qiáng)的電磁吸力把銜鐵往下吸引而頂開(kāi)鎖鉤，使主觸點(diǎn)斷開(kāi)。欠壓脫扣器的工作恰恰相反，在電壓正常時(shí)，電磁吸力吸住銜鐵，主觸點(diǎn)才得以閉合。一旦電壓嚴(yán)重下降或斷電時(shí)，銜鐵就被釋放而使主觸點(diǎn)斷開(kāi)。當(dāng)電源電壓恢復(fù)正常時(shí)，必須重新合閘后才能工作，實(shí)現(xiàn)了失壓保護(hù)。
