低壓電器有哪些分類方法

1、按用途和(he)(he)(he)控(kong)(kong)(kong)制(zhi)(zhi)對象不同，可將低壓電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)分為配(pei)電(dian)(dian)電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)和(he)(he)(he)控(kong)(kong)(kong)制(zhi)(zhi)電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)。用于(yu)(yu)電(dian)(dian)能的輸送和(he)(he)(he)分配(pei)的電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)稱為低壓配(pei)電(dian)(dian)電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)，這類電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)包括刀開關、轉換開關、空氣斷(duan)路(lu)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)和(he)(he)(he)熔斷(duan)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)等。用于(yu)(yu)各(ge)種(zhong)控(kong)(kong)(kong)制(zhi)(zhi)電(dian)(dian)路(lu)和(he)(he)(he)控(kong)(kong)(kong)制(zhi)(zhi)系統的電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)稱為控(kong)(kong)(kong)制(zhi)(zhi)電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)，這類電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)包括接觸器(qi)(qi)(qi)(qi)(qi)(qi)(qi)、起動(dong)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)和(he)(he)(he)各(ge)種(zhong)控(kong)(kong)(kong)制(zhi)(zhi)繼電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)等。

2、按操作方式不同，可將低(di)壓電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)分為(wei)自動(dong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)和手(shou)(shou)動(dong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)。通(tong)(tong)過電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)本身參數(shu)變化或外來信號（如(ru)電(dian)(dian)(dian)(dian)、磁、光(guang)、熱等）自動(dong)完(wan)成接(jie)通(tong)(tong)、分斷、起(qi)動(dong)、反(fan)向(xiang)和停(ting)止等動(dong)作的電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)稱(cheng)為(wei)自動(dong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)，常用的自動(dong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)有接(jie)觸器(qi)(qi)(qi)(qi)、繼電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)等。通(tong)(tong)過人力直接(jie)操作來完(wan)成接(jie)通(tong)(tong)、分斷、起(qi)動(dong)、反(fan)向(xiang)和停(ting)止等動(dong)作的電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)稱(cheng)為(wei)手(shou)(shou)動(dong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)。常用的手(shou)(shou)動(dong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)有刀開關(guan)、轉(zhuan)換開關(guan)和主令電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)等。

3、按(an)工(gong)作原(yuan)(yuan)理，低壓電(dian)(dian)(dian)器(qi)(qi)(qi)可分為電(dian)(dian)(dian)磁(ci)式電(dian)(dian)(dian)器(qi)(qi)(qi)和非(fei)電(dian)(dian)(dian)量(liang)(liang)控(kong)(kong)制電(dian)(dian)(dian)器(qi)(qi)(qi)。電(dian)(dian)(dian)磁(ci)式電(dian)(dian)(dian)器(qi)(qi)(qi)是(shi)依據電(dian)(dian)(dian)磁(ci)感(gan)應原(yuan)(yuan)理來(lai)工(gong)作的(de)(de)電(dian)(dian)(dian)器(qi)(qi)(qi)，如(ru)接(jie)觸器(qi)(qi)(qi)、各類(lei)電(dian)(dian)(dian)磁(ci)式繼電(dian)(dian)(dian)器(qi)(qi)(qi)等。非(fei)電(dian)(dian)(dian)量(liang)(liang)控(kong)(kong)制電(dian)(dian)(dian)器(qi)(qi)(qi)的(de)(de)工(gong)作是(shi)靠外力(li)或某(mou)種非(fei)電(dian)(dian)(dian)量(liang)(liang)的(de)(de)變化而(er)動作的(de)(de)電(dian)(dian)(dian)器(qi)(qi)(qi)，如(ru)行程(cheng)開關、速度(du)繼電(dian)(dian)(dian)器(qi)(qi)(qi)等。

常見低壓電器是怎么工作的

1、刀開關

刀開關(guan)又(you)稱為閘刀開關(guan)或隔離開關(guan)，它是通(tong)過底座(zuo)上的靜觸(chu)頭(tou)與刀夾座(zuo)相(xiang)楔合(he)（或分(fen)離），來控(kong)制電路接(jie)通(tong)（或分(fen)斷(duan)）的低壓(ya)電器(qi)設備。

2、熔斷器

熔(rong)斷(duan)器(qi)(qi)也被稱(cheng)為(wei)(wei)保險絲，IEC127標準(zhun)將它定義為(wei)(wei)“熔(rong)斷(duan)體(ti)（fuse-link）”。熔(rong)斷(duan)器(qi)(qi)的工(gong)作原理很簡單，當過載或短路電(dian)流通(tong)過熔(rong)斷(duan)器(qi)(qi)時，電(dian)流產生的熱量會使熔(rong)斷(duan)器(qi)(qi)中的熔(rong)體(ti)熔(rong)斷(duan)，從而保護電(dian)路不被損(sun)壞。

3、低壓斷路器

低壓(ya)斷路器(qi)曾被稱為自(zi)動開(kai)關(guan)，其工作原理與熔斷器(qi)差不多，但功能(neng)要多一(yi)點，它是一(yi)種(zhong)既(ji)有手動開(kai)關(guan)作用，又能(neng)自(zi)動進(jin)行(xing)失壓(ya)、欠壓(ya)、過載、和短路保護的(de)電器(qi)。

4、接觸器

接(jie)觸(chu)(chu)(chu)(chu)器(qi)主(zhu)要利用了電磁感應原理，當接(jie)觸(chu)(chu)(chu)(chu)器(qi)線(xian)圈(quan)(quan)通電后，線(xian)圈(quan)(quan)電流會產(chan)(chan)生(sheng)磁場(chang)，產(chan)(chan)生(sheng)的磁場(chang)使(shi)靜(jing)鐵(tie)(tie)芯(xin)產(chan)(chan)生(sheng)電磁吸力(li)吸引(yin)動(dong)鐵(tie)(tie)芯(xin)，并(bing)帶動(dong)交流接(jie)觸(chu)(chu)(chu)(chu)器(qi)點(dian)(dian)(dian)動(dong)作，常(chang)閉(bi)觸(chu)(chu)(chu)(chu)點(dian)(dian)(dian)斷(duan)開，常(chang)開觸(chu)(chu)(chu)(chu)點(dian)(dian)(dian)閉(bi)合(he)。當線(xian)圈(quan)(quan)斷(duan)電時，電磁吸力(li)消失(shi)，銜鐵(tie)(tie)在(zai)釋放彈簧的作用下釋放，使(shi)觸(chu)(chu)(chu)(chu)點(dian)(dian)(dian)復原，常(chang)開觸(chu)(chu)(chu)(chu)點(dian)(dian)(dian)斷(duan)開，常(chang)閉(bi)觸(chu)(chu)(chu)(chu)點(dian)(dian)(dian)閉(bi)合(he)。

5、繼電器

繼電器有(you)(you)很多種類(lei)，不同類(lei)型的繼電器，工作原(yuan)理略(lve)有(you)(you)不同，但(dan)它們的基本(ben)原(yuan)理是相似的，都利(li)用了電磁(ci)效應來(lai)控(kong)制機械觸點，來(lai)而達到通斷目的。
