空氣開關是(shi)低(di)壓配電(dian)網絡和(he)(he)電(dian)力拖動系統(tong)中(zhong)非常重要的一(yi)(yi)種電(dian)器，它集控制和(he)(he)多種保(bao)護(hu)功能于一(yi)(yi)身。它的內(nei)部結構(gou)由(you)四(si)大部分組成(cheng)，下面就請(qing)跟隨一(yi)(yi)起裝修網的小編(bian)一(yi)(yi)起去了解一(yi)(yi)下空氣(qi)開關內(nei)部四(si)大組成(cheng)附件吧。

空氣開關

附件一 輔助觸頭

輔助觸(chu)(chu)頭是斷路(lu)(lu)器(qi)(qi)(qi)主電(dian)(dian)(dian)(dian)路(lu)(lu)分(fen)、合(he)機構(gou)機械上連動的觸(chu)(chu)頭，主要用于斷路(lu)(lu)器(qi)(qi)(qi)分(fen)、合(he)狀態的顯(xian)示，接(jie)在斷路(lu)(lu)器(qi)(qi)(qi)的控制(zhi)電(dian)(dian)(dian)(dian)路(lu)(lu)中通過斷路(lu)(lu)器(qi)(qi)(qi)的分(fen)合(he)，對其相(xiang)(xiang)關電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)實施控制(zhi)或(huo)聯鎖。例如向信(xin)號(hao)燈(deng)、繼電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)等(deng)輸出信(xin)號(hao)。塑殼斷路(lu)(lu)器(qi)(qi)(qi)殼架等(deng)級額(e)定電(dian)(dian)(dian)(dian)流(liu)(liu)100A為(wei)單斷點轉(zhuan)換觸(chu)(chu)頭，225A及以(yi)上為(wei)橋式觸(chu)(chu)頭結構(gou)，約(yue)(yue)定發(fa)熱(re)電(dian)(dian)(dian)(dian)流(liu)(liu)為(wei)3A；殼架等(deng)級額(e)定電(dian)(dian)(dian)(dian)流(liu)(liu)400A及以(yi)上可裝兩常開、兩常閉，約(yue)(yue)定發(fa)熱(re)電(dian)(dian)(dian)(dian)流(liu)(liu)為(wei)6A。操(cao)作(zuo)性(xing)能次(ci)數與(yu)斷路(lu)(lu)器(qi)(qi)(qi)的操(cao)作(zuo)性(xing)能總次(ci)數相(xiang)(xiang)同。

附件二 報警觸頭

用于(yu)(yu)斷(duan)路(lu)(lu)(lu)器(qi)事故的(de)報警觸頭，且此(ci)觸頭只有當斷(duan)路(lu)(lu)(lu)器(qi)脫扣分斷(duan)后(hou)才動作，主要用于(yu)(yu)斷(duan)路(lu)(lu)(lu)器(qi)的(de)負(fu)載(zai)出現過載(zai)短路(lu)(lu)(lu)或(huo)欠電壓等故障(zhang)時而自由脫扣，報警觸頭從原來的(de)常開位置轉換成閉合位置，接通輔(fu)助線路(lu)(lu)(lu)中(zhong)的(de)指示(shi)燈(deng)或(huo)電鈴、蜂鳴器(qi)等，顯示(shi)或(huo)提醒斷(duan)路(lu)(lu)(lu)器(qi)的(de)故障(zhang)脫扣狀(zhuang)態。

由于斷路(lu)器發生(sheng)因負載(zai)故障而自(zi)由脫扣的機(ji)率不(bu)太多，因而報警(jing)觸(chu)頭的壽命是(shi)斷路(lu)器壽命的1/10。報警(jing)觸(chu)頭的工作電(dian)流一般(ban)不(bu)會超(chao)過1A。

附件三 分勵脫扣器

是一種用(yong)電(dian)(dian)(dian)(dian)壓(ya)源激勵(li)的(de)(de)脫(tuo)(tuo)(tuo)扣(kou)器(qi)(qi)(qi)，它的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)可(ke)與主電(dian)(dian)(dian)(dian)路(lu)電(dian)(dian)(dian)(dian)壓(ya)無關(guan)。分(fen)(fen)(fen)勵(li)脫(tuo)(tuo)(tuo)扣(kou)器(qi)(qi)(qi)是一種遠(yuan)距離操縱(zong)分(fen)(fen)(fen)閘的(de)(de)附件。當電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)等于(yu)額定控(kong)制電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)的(de)(de)70%-110%之間的(de)(de)任一電(dian)(dian)(dian)(dian)壓(ya)時，就(jiu)(jiu)能可(ke)靠(kao)分(fen)(fen)(fen)斷(duan)(duan)斷(duan)(duan)路(lu)器(qi)(qi)(qi)。分(fen)(fen)(fen)勵(li)脫(tuo)(tuo)(tuo)扣(kou)器(qi)(qi)(qi)是短時工作制，線(xian)圈(quan)(quan)通(tong)電(dian)(dian)(dian)(dian)時間一般不能超過1S，否則線(xian)會(hui)被燒(shao)毀。塑殼斷(duan)(duan)路(lu)器(qi)(qi)(qi)為防止線(xian)圈(quan)(quan)燒(shao)毀，在分(fen)(fen)(fen)勵(li)脫(tuo)(tuo)(tuo)扣(kou)線(xian)圈(quan)(quan)串聯一個微(wei)動(dong)開(kai)關(guan)，當分(fen)(fen)(fen)勵(li)脫(tuo)(tuo)(tuo)扣(kou)器(qi)(qi)(qi)通(tong)過銜鐵吸合(he)，微(wei)動(dong)開(kai)關(guan)從常(chang)(chang)閉狀態(tai)轉(zhuan)換成常(chang)(chang)開(kai)，由于(yu)分(fen)(fen)(fen)勵(li)脫(tuo)(tuo)(tuo)扣(kou)器(qi)(qi)(qi)電(dian)(dian)(dian)(dian)源的(de)(de)控(kong)制線(xian)路(lu)被切斷(duan)(duan)，即使人為地按(an)住(zhu)按(an)鈕，分(fen)(fen)(fen)勵(li)線(xian)圈(quan)(quan)始終不再通(tong)電(dian)(dian)(dian)(dian)就(jiu)(jiu)避免(mian)了線(xian)圈(quan)(quan)燒(shao)損情況的(de)(de)產生。當斷(duan)(duan)路(lu)器(qi)(qi)(qi)再扣(kou)合(he)閘后，微(wei)動(dong)開(kai)關(guan)重新處于(yu)常(chang)(chang)閉位置(zhi)。
