低壓電器有哪些分類方法

1、按(an)用(yong)途和(he)控制(zhi)對象不(bu)同，可將低壓電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)分(fen)為(wei)(wei)配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)和(he)控制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)。用(yong)于電(dian)(dian)(dian)(dian)(dian)(dian)能的輸送和(he)分(fen)配(pei)的電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)稱為(wei)(wei)低壓配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)，這類電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)包括(kuo)刀開關、轉換開關、空氣(qi)斷(duan)路器(qi)(qi)(qi)(qi)和(he)熔斷(duan)器(qi)(qi)(qi)(qi)等。用(yong)于各(ge)種控制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路和(he)控制(zhi)系統的電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)稱為(wei)(wei)控制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)，這類電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)包括(kuo)接觸(chu)器(qi)(qi)(qi)(qi)、起動(dong)器(qi)(qi)(qi)(qi)和(he)各(ge)種控制(zhi)繼電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)等。

2、按操作(zuo)方式不同，可(ke)將低壓電器(qi)(qi)分為(wei)自動(dong)(dong)電器(qi)(qi)和手(shou)動(dong)(dong)電器(qi)(qi)。通(tong)過(guo)(guo)電器(qi)(qi)本身(shen)參數(shu)變化(hua)或外來信號（如電、磁、光、熱等）自動(dong)(dong)完成接(jie)通(tong)、分斷(duan)、起(qi)動(dong)(dong)、反(fan)向和停止等動(dong)(dong)作(zuo)的電器(qi)(qi)稱(cheng)為(wei)自動(dong)(dong)電器(qi)(qi)，常用的自動(dong)(dong)電器(qi)(qi)有接(jie)觸器(qi)(qi)、繼(ji)電器(qi)(qi)等。通(tong)過(guo)(guo)人力直接(jie)操作(zuo)來完成接(jie)通(tong)、分斷(duan)、起(qi)動(dong)(dong)、反(fan)向和停止等動(dong)(dong)作(zuo)的電器(qi)(qi)稱(cheng)為(wei)手(shou)動(dong)(dong)電器(qi)(qi)。常用的手(shou)動(dong)(dong)電器(qi)(qi)有刀開關、轉換開關和主(zhu)令電器(qi)(qi)等。

3、按工作原理(li)，低壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)可分為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)和(he)非電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量控制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)是(shi)依(yi)據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁感(gan)應原理(li)來(lai)工作的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，如接(jie)觸器(qi)(qi)(qi)、各類電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁式(shi)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)等(deng)。非電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量控制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的工作是(shi)靠(kao)外力或某種非電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量的變化(hua)而動作的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，如行程開關、速度繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)等(deng)。

常見低壓電器是怎么工作的

1、刀開關

刀開(kai)關(guan)又稱為閘刀開(kai)關(guan)或(huo)隔離(li)開(kai)關(guan)，它(ta)是通過底座上(shang)的靜觸頭與刀夾座相楔(xie)合（或(huo)分離(li)），來控制電路接(jie)通（或(huo)分斷(duan)）的低(di)壓電器設備(bei)。

2、熔斷器

熔斷(duan)器(qi)也被稱為保(bao)險絲，IEC127標準將它(ta)定義為“熔斷(duan)體（fuse-link）”。熔斷(duan)器(qi)的(de)工作原理很(hen)簡單，當過載或(huo)短路電流(liu)(liu)通過熔斷(duan)器(qi)時，電流(liu)(liu)產生的(de)熱量(liang)會(hui)使熔斷(duan)器(qi)中(zhong)的(de)熔體熔斷(duan)，從而保(bao)護(hu)電路不被損壞。

3、低壓斷路器

低壓(ya)斷(duan)路器曾被(bei)稱為自(zi)動(dong)開(kai)關，其工(gong)作(zuo)原理與熔斷(duan)器差不多(duo)，但功(gong)能要多(duo)一(yi)點(dian)，它(ta)是一(yi)種既有手動(dong)開(kai)關作(zuo)用，又能自(zi)動(dong)進(jin)行失壓(ya)、欠壓(ya)、過載、和短路保護的電器。

4、接觸器

接(jie)觸(chu)(chu)器(qi)主要利用了電(dian)磁(ci)感應原理(li)，當接(jie)觸(chu)(chu)器(qi)線(xian)圈通電(dian)后，線(xian)圈電(dian)流(liu)會產(chan)生磁(ci)場，產(chan)生的磁(ci)場使靜(jing)鐵芯產(chan)生電(dian)磁(ci)吸(xi)力吸(xi)引(yin)動(dong)鐵芯，并帶動(dong)交流(liu)接(jie)觸(chu)(chu)器(qi)點(dian)動(dong)作，常閉(bi)觸(chu)(chu)點(dian)斷開(kai)，常開(kai)觸(chu)(chu)點(dian)閉(bi)合。當線(xian)圈斷電(dian)時(shi)，電(dian)磁(ci)吸(xi)力消失，銜鐵在(zai)釋放(fang)彈簧的作用下釋放(fang)，使觸(chu)(chu)點(dian)復原，常開(kai)觸(chu)(chu)點(dian)斷開(kai)，常閉(bi)觸(chu)(chu)點(dian)閉(bi)合。

5、繼電器

繼(ji)電(dian)器有很多種類(lei)，不(bu)(bu)同類(lei)型的(de)繼(ji)電(dian)器，工(gong)作(zuo)原(yuan)理略(lve)有不(bu)(bu)同，但它們的(de)基(ji)本(ben)原(yuan)理是相似的(de)，都利用了電(dian)磁效應來控制機械觸點，來而達到通斷目的(de)。
