<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。

<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。
