每路線的插座、燈頭、廚房、衛(wèi)生間、冰箱、空調(diào)都應(yīng)該單獨(dú)放線，每路線上都要有單獨(dú)的空氣開關(guān)，大功率的房間，比如廚房和衛(wèi)生間，4平方毫米以上的線路要達(dá)到20A，一般的燈頭線只要16A，每條線路都有特定的規(guī)格。 </p> <p> 在檢測(cè)空氣開關(guān)是否正常的時(shí)候，應(yīng)該請(qǐng)專業(yè)人員用漏電相位檢測(cè)儀檢測(cè)。如果空氣開關(guān)處于正常保護(hù)狀態(tài)，檢測(cè)的時(shí)候，每路電的空氣開關(guān)都會(huì)單獨(dú)跳閘，漏電保護(hù)器也跟著一起跳閘。如果空氣開關(guān)處于不正常的狀態(tài)，那么只是總開關(guān)跳閘，單獨(dú)的空氣開關(guān)不跳閘，漏電保護(hù)器也不跳閘。

低壓斷路器的主觸點(diǎn)是靠手動(dòng)操作或電動(dòng)合閘的。主觸點(diǎn)閉合后，自由脫扣機(jī)構(gòu)將主觸點(diǎn)鎖在合閘位置上。過電流脫扣器的線圈和熱脫扣器的熱元件與主電路串聯(lián)，欠電壓脫扣器的線圈和電源并聯(lián)。 </p> <p> 當(dāng)電路發(fā)生短路或嚴(yán)重過載時(shí)，過電流脫扣器的銜鐵吸合，使自由脫扣機(jī)構(gòu)動(dòng)作，主觸點(diǎn)斷開主電路。 </p> <p> 當(dāng)電路過載時(shí)，熱脫扣器的熱元件發(fā)熱使雙金屬片上彎曲，推動(dòng)自由脫扣機(jī)構(gòu)動(dòng)作，主觸點(diǎn)斷開主電路。 </p> <p> 當(dāng)電路欠電壓時(shí)，欠電壓脫扣器的銜鐵釋放，也使自由脫扣機(jī)構(gòu)動(dòng)作，主觸點(diǎn)斷開主電路。 </p> <p> 當(dāng)按下分勵(lì)脫扣按鈕時(shí)，分勵(lì)脫扣器銜鐵吸合，使自由脫扣機(jī)構(gòu)動(dòng)作，主觸點(diǎn)斷開主電路。 </p> <p> <br /> </p> <p> <br /> 油斷路器的概念是怎樣的？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="ETAON 塑殼斷路器NZMC3-4-A500-E,塑殼斷路器"

4.過載延時(shí)保護(hù)：過載延時(shí)保護(hù)是指負(fù)荷電流超過設(shè)備的限定范圍有燒毀設(shè)備的危險(xiǎn)，保護(hù)裝置能在一定時(shí)間內(nèi)切斷電源。過載有個(gè)熱量積累的過程，保護(hù)動(dòng)作不需要過于迅速。對(duì)于短時(shí)過電流，保護(hù)不應(yīng)該動(dòng)作。 </p> <p> 5.隔離功能：隔離功能就是要求斷路器斷開后的泄漏電流不致對(duì)人身和設(shè)備產(chǎn)生危害。多次短路跳閘后開關(guān)性能下降，泄漏電流會(huì)增大。對(duì)人體而言30mA以下為安全漏電電流，而在惡劣的環(huán)境中，超過300mA的泄漏電流持續(xù)2小時(shí)以上，就可能使絕緣損壞發(fā)生相地短路進(jìn)而引發(fā)火災(zāi)。 </p>

<strong>塑殼斷路器</strong>的工作原理 </p> <p> 聯(lián)鎖裝置有機(jī)械聯(lián)鎖和電氣聯(lián)鎖兩種類型。工作原理是： </p> <p> （1）機(jī)械聯(lián)鎖裝置一般使用鋼絲繩或者杠桿機(jī)構(gòu)，以機(jī)械位置的變動(dòng)（也可采用多功能程序鎖）來保證在斷路器切斷電源以前，隔離開關(guān)的操作把手不能動(dòng)作。 </p> <p> （2）電氣聯(lián)鎖裝置電氣聯(lián)鎖一般有兩種聯(lián)鎖方式，一種是通過操作機(jī)構(gòu)上的聯(lián)動(dòng)輔助接點(diǎn)（常開或常閉）去控制隔離開關(guān)的把手。當(dāng)斷路器未斷開時(shí)，隔離開關(guān)操作把手不能動(dòng)作。 </p> <p> 另一種電氣聯(lián)鎖是利用距離開關(guān)操作機(jī)構(gòu)上的聯(lián)動(dòng)輔助接點(diǎn)（常開或常閉）去控制斷路器。當(dāng)拉動(dòng)隔離開關(guān)的把手時(shí)，聯(lián)動(dòng)輔助接點(diǎn)（常開或常閉）使斷路器動(dòng)作以切斷電路，從而可防止帶負(fù)荷拉動(dòng)距離開關(guān)的事故。
