分勵脫扣器：是一種用電壓源激勵的脫扣器，它的電壓可與主電路電壓無關(guān)。分勵脫扣器是一種遠(yuǎn)距離操縱分閘的附件。當(dāng)電源電壓等于額定控制電源電壓的70%-110%之間的任一電壓時，就能可靠分?jǐn)鄶嗦菲?。分勵脫扣器是短時工作制，線圈通電時間一般不能超過1S，否則線會被燒毀。塑殼斷路器為防止線圈燒毀，在分勵脫扣線圈串聯(lián)一個微動開關(guān)，當(dāng)分勵脫扣器通過銜鐵吸合，微動開關(guān)從常閉狀態(tài)轉(zhuǎn)換成常開，由于分勵脫扣器電源的控制線路被切斷，即使人為地按住按鈕，分勵線圈始終不再通電就避免了線圈燒損情況的產(chǎn)生。當(dāng)斷路器再扣合閘后，微動開關(guān)重新處于常閉位置。

2.在系統(tǒng)發(fā)生故障時能與保護(hù)裝置和自動裝置相配合迅速切斷故障電流防止事故擴(kuò)大從而保證系統(tǒng)安全運(yùn)行。 </p> <p> 一般情況下塑殼斷路器本身不存在潤滑方面的問題，需要潤滑的常常是它的操動機(jī)構(gòu)。熱繼電器的作用是電動機(jī)過負(fù)荷時自動切斷電源，熱繼電器的構(gòu)造是兩片膨脹系數(shù)不同的金屬片構(gòu)成，電流過大時膨脹系數(shù)大的先膨脹，起到切斷電源的作用。熱繼電器動作后有人工復(fù)位和自動復(fù)位。熔斷器作用：當(dāng)電路發(fā)生故障或異常時，伴隨著電流不斷升高，并且升高的電流有可能損壞電路中的某些重要器件或貴重器件，也有可能燒毀電路甚至造成火災(zāi)。
