輔助觸頭：輔助觸頭是斷路器主電路分、合機(jī)構(gòu)機(jī)械上連動(dòng)的觸頭，主要用于斷路器分、合狀態(tài)的顯示，接在斷路器的控制電路中通過斷路器的分合，對其相關(guān)電器實(shí)施控制或聯(lián)鎖。例如向信號燈、繼電器等輸出信號。塑殼斷路器殼架等級額定電流100A為單斷點(diǎn)轉(zhuǎn)換觸頭，225A及以上為橋式觸頭結(jié)構(gòu)，約定發(fā)熱電流為3A；殼架等級額定電流400A及以上可裝兩常開、兩常閉，約定發(fā)熱電流為6A。操作性能次數(shù)與斷路器的操作性能總次數(shù)相同。

（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。

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 />
