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)。

1.額定極限短路分?jǐn)嗄芰cu：斷路器的分?jǐn)嗄芰χ笜?biāo)有兩種：額定極限短路分?jǐn)嗄芰cu和額定運(yùn)行短路分?jǐn)嗄芰cs。Ics作為一個(gè)特性參數(shù)，并非只簡單考慮斷路器的分?jǐn)嗄芰Γ亲鳛橐环N分?jǐn)嘀笜?biāo)，即分?jǐn)鄮状味搪饭收虾?，還能保證其正常工作。 </p> <p> 2.限流分?jǐn)嗄芰Γ簲嗦菲靼l(fā)生短路時(shí)、觸頭快速打開產(chǎn)生電弧，相當(dāng)于在線路中串入1個(gè)迅速增加的電弧電阻，從而限制了故障電流的增加。斷路器斷開時(shí)間越少，Ics就越接近Icu，限流效果就越好，也可**降低短路電流引起的電磁效應(yīng)、電動(dòng)效應(yīng)和熱效應(yīng)對(duì)斷路器和用電設(shè)備的不良影響，延長斷路器的使用壽命。 </p> <p> 3.短路保護(hù)：短路保護(hù)就是短路瞬時(shí)跳閘。要注意在負(fù)荷變化后及時(shí)調(diào)整保護(hù)的整定值，防止整定值過小頻繁跳閘影響供電質(zhì)量，或整定值過大使線路和設(shè)備得不到有效保護(hù)。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 空氣斷路器的常見故障 </p> <p> 跳閘： </p> <p> 首先判斷跳閘的空氣開關(guān)是家中配電箱內(nèi)的總開關(guān)還是分路出線開關(guān)。如總開關(guān)未跳閘，只是分路開關(guān)跳閘，則說明大功率電器供電線路接線有問題，即多件大功率電器接在同一分路開關(guān)上，此類情況，將大功率電器線路調(diào)整至負(fù)荷輕的分路開關(guān)即可（建議大功率電器使用單獨(dú)的分路開關(guān)）；如分路開關(guān)沒跳閘，總開關(guān)跳閘，則計(jì)算家用電器功率之和是否超出供電認(rèn)可容量，并檢查總開關(guān)容量是否與供電認(rèn)可容量匹配。如家用電器功率之和超出供電認(rèn)可容量，則減少同時(shí)使用的家用電器數(shù)量（特別是大功率家用電器），并向供電公司申請(qǐng)用電增容；如家用電器功率之和未超出供電認(rèn)可容量，同時(shí)需要提醒的是，部分大功率電器啟動(dòng)電流較大，計(jì)算功率時(shí)應(yīng)考慮啟動(dòng)電流造成的影響。
