塑殼斷路器內(nèi)部結(jié)構(gòu) </p> <p> 斷路器是用于合斷電源，同時(shí)具有瞬時(shí)過(guò)電流保護(hù)及延時(shí)過(guò)電流保護(hù)（有些品種還具有欠電壓保護(hù)）的開(kāi)關(guān)元件。其瞬時(shí)過(guò)電流保護(hù)又被稱為短路保護(hù)；延時(shí)過(guò)電流保護(hù)又被稱為過(guò)載或過(guò)熱保護(hù)。這種開(kāi)關(guān)又常被稱為“空氣開(kāi)關(guān)”。 </p> <p> 較常用的斷路器為塑料殼式，現(xiàn)用的國(guó)產(chǎn)品種型號(hào)為DZ10和DZ**Z5型在較小電流的場(chǎng)合還有應(yīng)用。均具有瞬時(shí)過(guò)電流保護(hù)（或稱為短路保護(hù)）及延時(shí)過(guò)電流保護(hù)（或稱為過(guò)載保護(hù)），圖4-6為DZ5和DZ20型的外形圖，DZ10和DZ20型的結(jié)構(gòu)如圖4-7～圖4-9所示。一般的品種，要調(diào)節(jié)過(guò)電流保護(hù)值，須將其蓋打開(kāi)方可進(jìn)行。

附件作為斷路器功能的派生和補(bǔ)充，為斷路器增加了控制手段和擴(kuò)大保護(hù)功能，是斷路器不可分割的一個(gè)重要部分，主要包括輔助觸頭、報(bào)警觸頭、分勵(lì)脫扣器、欠電壓脫扣器、電動(dòng)操作機(jī)構(gòu)、外部轉(zhuǎn)動(dòng)操作手柄等附件。 </p> <p> 1)輔助觸頭主要用于斷路器分、合狀態(tài)顯示但無(wú)法顯示是否故障脫扣，接在斷路器的控制電路中，塑殼斷路器殼架等級(jí)額定電流100為單斷點(diǎn)轉(zhuǎn)換觸頭，225及以上為橋式觸頭結(jié)構(gòu)，約定發(fā)熱電流3A；殼架等級(jí)額定電流400及以上可裝兩常開(kāi)、兩常閉，約定發(fā)熱電流為6A。 </p> <p> 2)報(bào)警觸頭主要用于斷路器的負(fù)載出現(xiàn)過(guò)載、短路或欠電壓等故障時(shí)而自由脫扣。報(bào)警觸頭的工作電流是：AC380V、0.3A、DC220V、0.15A，一般不會(huì)超過(guò)1A，而發(fā)熱電流可以是1～2.5A范圍。 </p> <p> <br /> </p> <p> <br />

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(wú)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(guò)電流脫扣器的應(yīng)用，塑殼斷路器也可分為A類(lèi)和B類(lèi)兩種，B類(lèi)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(lèi)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(kāi)關(guān)，過(guò)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(guò)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(guò)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)。
