</p> <p> <br /> </p> <p> <br /> </p> <p> <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)。
