輔助觸頭:與斷路器主電路分、合機構機械上連動的觸頭,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,對其相關電器實施控制或聯(lián)鎖。例如向信號燈、繼電器等輸出信號。塑殼斷路
器殼架等*額定電流100A為單斷點轉換觸頭,225A及以上為橋式觸頭結構,約定發(fā)熱電流為3A殼架等*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。操作能次數(shù)與斷路器的操作能總次數(shù)相同
觸頭:用于斷路器事故的觸頭,且此觸頭只有當斷路器脫扣分斷后才動作,主要用于斷路器的負載出
現(xiàn)過載短路或欠電壓等故障時而自由脫扣,觸頭從原來的常開位置轉換成閉合位置,接通輔助線路中的指
示燈或電鈴、蜂鳴器等,顯示或提酲斷路器的故障脫扣狀態(tài)。由于斷路器發(fā)生因負載故障而自由脫扣的機率不
太多,因而觸頭的壽命是斷路器壽命的1/10。觸頭的工作電流一般不會1A
分勵脫扣器:分勵脫扣器是一種用電壓源激勵的脫扣器,它的電壓與主電路電壓無關。分勵脫扣器是一種遠距
離操縱分閘的附件。當電源電壓等于額定控制電源電壓的70%-110%之間的任一電壓時,就能可靠的分斷斷
路器。分勵脫扣器是短時工作制,線圈通電時間一般不能15,否則線就會被燒毀。塑殼斷路器為防止線圈燒
毀,在分勵脫扣線圈串聯(lián)一個微動開關,當分勵脫扣器通過銜鐵吸合,微動開關從常閉狀態(tài)轉換成常開,由于
分勵脫扣器電源的控制線路被切斷,即使人為的按住按鈕,分勵線圈始終不會再通電這就避免了線圈燒損情況
的產(chǎn)生。當斷路器再扣合閘后,微動開關重新處于常閉位置
欠電壓脫扣器:欠電壓脫扣器是在它的端電壓降至某一規(guī)定范圍時,使斷路器有延時或無延時斷開的一種脫扣
器,當電源電壓下降(甚至緩慢下降)到額定工作電壓的70%至35%范圍內,欠電壓脫扣器應運作,欠
扣器
在電源電壓等于脫扣器額定工作電壓的35%時,欠電壓脫扣器應能防止斷路器閉合;電源電壓等于或大于85%欠
電壓脫扣器的額定工作電壓時,在熱態(tài)條件下,應能*證斷路器可靠閉合。因此,當受保護電路中電源電壓發(fā)
生一定的電壓降時,能自動斷開斷路器切斷電源,使該斷路器以下的負載電器或電氣設備免受欠電壓的損壞
使用時,欠電壓脫扣器線圈接在斷路器電源側,欠電壓脫扣器通電后,斷路器才能合閘
