<strong>塑殼斷路器</strong>的簡(jiǎn)介 </p> <p> 塑殼斷路器也被稱為裝置式斷路器，所有的零件都密封于塑料外殼中，輔助觸點(diǎn)，欠電壓脫扣器以及分勵(lì)脫扣器等多采用模塊化。由于結(jié)構(gòu)非常緊湊，塑殼斷路器基本無法檢修。其多采用手動(dòng)操作，大容量可選擇電動(dòng)分合。由于電子式過電流脫扣器的應(yīng)用，塑殼斷路器也可分為A類和B類兩種，B類具有良好的三段保護(hù)特性，但由于價(jià)格因素，采用熱磁式脫扣器的A類產(chǎn)品的市場(chǎng)占有率更高。塑殼斷路器是將觸頭、滅弧室、脫扣器和操作機(jī)構(gòu)等都裝在一個(gè)塑料外殼內(nèi)，一般不考慮維修，適用于作支路的保護(hù)開關(guān)，過電流脫扣器有熱磁式和電子式兩種，一般熱磁式塑殼斷路器為非選擇性斷路器，*有過載長(zhǎng)延時(shí)及短路瞬時(shí)兩種保護(hù)方式，電子式塑殼斷路器有過載長(zhǎng)延時(shí)、短路短延時(shí)、短路瞬時(shí)和接地故障四種保護(hù)功能。部分電子式塑殼斷路器新推出的產(chǎn)品還帶有區(qū)域選擇性連鎖功能。大多數(shù)塑殼斷路器為手動(dòng)操作，也有部分帶電動(dòng)機(jī)操作機(jī)構(gòu)。

<strong>塑殼斷路器</strong>的作用 </p> <p> 1.正常倩況下接通和斷開高壓電路中的空載及負(fù)荷電流; </p> <p> 2.在系統(tǒng)發(fā)生故障時(shí)能與保護(hù)裝置和自動(dòng)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(rùn)滑方面的問題，需要潤(rùn)滑的常常是它的操動(dòng)機(jī)構(gòu)。熱繼電器的作用是電動(dòng)機(jī)過負(fù)荷時(shí)自動(dòng)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(shí)膨脹系數(shù)大的先膨脹，起到切斷電源的作用。熱繼電器動(dòng)作后有人工復(fù)位和自動(dòng)復(fù)位。熔斷器作用：當(dāng)電路發(fā)生故障或異常時(shí)，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)。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 空氣斷路器的內(nèi)部附件（三） </p> <p> 分勵(lì)脫扣器：是一種用電壓源激勵(lì)的脫扣器，它的電壓可與主電路電壓無關(guān)。分勵(lì)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(shí)，就能可靠分?jǐn)鄶嗦菲?。分?lì)脫扣器是短時(shí)工作制，線圈通電時(shí)間一般不能超過1S，否則線會(huì)被燒毀。塑殼斷路器為防止線圈燒毀，在分勵(lì)脫扣線圈串聯(lián)一個(gè)微動(dòng)開關(guān)，當(dāng)分勵(lì)脫扣器通過銜鐵吸合，微動(dòng)開關(guān)從常閉狀態(tài)轉(zhuǎn)換成常開，由于分勵(lì)脫扣器電源的控制線路被切斷，即使人為地按住按鈕，分勵(lì)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(dòng)開關(guān)重新處于常閉位置。
