塑殼斷路器廣泛應(yīng)用于工農(nóng)業(yè)、交通、礦山、民用建筑和**等部門，對(duì)電力的傳輸和分配、電路的控制與保護(hù)起很大作用，是一種使用量大，面廣的產(chǎn)品。由于使用者對(duì)塑殼斷路器的特性和技術(shù)要求了解不深或不***，有些概念容易互相混淆，在實(shí)際應(yīng)用中就經(jīng)常出現(xiàn)一些偏失和誤解。本文對(duì)用戶在選擇和使用塑殼斷路器時(shí)容易出現(xiàn)的問(wèn)題做一介紹，以幫助用戶合理選擇使用塑殼斷路器。 </p> <p> 斷路器殼架等級(jí)額定電流是指基本尺寸相同的框架和塑料外殼中能裝的比較大脫扣器的額定電流。 </p> <p> <br /> </p> <p> <br /> 塑殼斷路器的特性有哪些？伊頓穆勒塑殼斷路器NZMC1-4-A100</p><p style="text-indent:25px">塑殼斷路器的主要參數(shù)。伊頓穆勒 ETAON NZM塑殼斷路器NZMS1-S63-E</p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <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(lái)保證在斷路器切斷電源以前，隔離開(kāi)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(guò)操作機(jī)構(gòu)上的聯(lián)動(dòng)輔助接點(diǎn)（常開(kāi)或常閉）去控制隔離開(kāi)關(guān)的把手。當(dāng)斷路器未斷開(kāi)時(shí)，隔離開(kāi)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(kāi)關(guān)操作機(jī)構(gòu)上的聯(lián)動(dòng)輔助接點(diǎn)（常開(kāi)或常閉）去控制斷路器。當(dāng)拉動(dòng)隔離開(kāi)關(guān)的把手時(shí)，聯(lián)動(dòng)輔助接點(diǎn)（常開(kāi)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(kāi)關(guān)的事故。
