中間繼(ji)電(dian)器的工(gong)作原理

什(shen)麽(me)是繼(ji)電(dian)器

繼(ji)電(dian)器就是用小電(dian)流控制(zhi)大(da)電(dian)流，由控(kong)制(zhi)回路(lu)和負(fu)載(zai)回路(lu)組(zu)成在自動(dong)控(kong)制(zhi)電(dian)路中，相當(dang)於自動(dong)開(kai)關(guan)。用(yong)於(yu)控(kong)制(zhi)電(dian)路，保(bao)護電(dian)路，轉(zhuan)換(huan)電(dian)路。

中間繼(ji)電(dian)器工(gong)作原理：

線圈(quan)通電(dian)，動(dong)鐵芯在(zai)電(dian)磁力(li)作用下(xia)動(dong)作吸合(he)，帶(dai)動(dong)動(dong)觸點動(dong)作，使常(chang)閉(bi)觸點分(fen)開，常(chang)開(kai)觸點閉(bi)合；線圈(quan)斷電(dian)，動(dong)鐵芯在(zai)彈(dan)簧的作用下(xia)帶(dai)動(dong)動(dong)觸點復位(wei)，繼(ji)電(dian)器的工(gong)作原理是當(dang)某壹輸入量(如電(dian)壓、電(dian)流、溫度(du)、速(su)度、壓力(li)等(deng))達到預(yu)定(ding)數(shu)值(zhi)時(shi)，使(shi)它(ta)動(dong)作，以(yi)改變(bian)控制(zhi)電(dian)路的工(gong)作狀(zhuang)態，從(cong)而實(shi)現既定(ding)的控(kong)制(zhi)或(huo)保(bao)護的目(mu)的。在(zai)此過程(cheng)中(zhong)，中(zhong)間繼(ji)電(dian)器主(zhu)要(yao)起(qi)了傳遞(di)信號(hao)的作用。

中間繼(ji)電(dian)器組成：

中間繼(ji)電(dian)器就是壹個繼(ji)電(dian)器，是由：固(gu)定(ding)鐵芯、動(dong)鐵芯、彈(dan)簧、動(dong)觸點、靜觸點、線圈(quan)、接線端子(zi)和外(wai)殼(ke)組成。

繼(ji)電(dian)器分(fen)類：

繼(ji)電(dian)器主(zhu)要(yao)分(fen)為壹般繼(ji)電(dian)器和固(gu)態(tai)繼(ji)電(dian)器。壹般繼(ji)電(dian)器把控(kong)制(zhi)信號(hao)轉(zhuan)換(huan)成機械(xie)式動(dong)作的電(dian)磁鐵和開(kai)關(guan)電(dian)氣的開(kai)關(guan)構成，中間繼(ji)電(dian)器就是*基本的繼(ji)電(dian)器。

固(gu)態(tai)繼(ji)電(dian)器是壹種(zhong)無觸點繼(ji)電(dian)器。由微電(dian)子電(dian)路，分(fen)立電(dian)子器件，電(dian)力(li)電(dian)子功率(lv)器件組成。可以(yi)分(fen)為輸入電(dian)路，電(dian)氣隔(ge)離部(bu)分(fen)，輸出(chu)電(dian)路組成。

中間繼(ji)電(dian)器的作用：

壹般的電(dian)路常(chang)分(fen)成主(zhu)電(dian)路和控(kong)制(zhi)電(dian)路兩(liang)部(bu)分(fen)，繼(ji)電(dian)器主(zhu)要(yao)用(yong)於(yu)控(kong)制(zhi)電(dian)路，接觸器主(zhu)要(yao)用(yong)於(yu)主(zhu)電(dian)路；通過繼(ji)電(dian)器可實(shi)現用(yong)壹路控(kong)制(zhi)信號(hao)控制(zhi)另壹路或(huo)幾(ji)路信號(hao)的功能(neng)，完(wan)成啟動(dong)、停(ting)止(zhi)、聯(lian)動(dong)等(deng)控(kong)制(zhi)，主(zhu)要(yao)控(kong)制(zhi)對(dui)象是接觸器；接觸器的觸頭比(bi)較(jiao)大，承(cheng)載(zai)能(neng)力(li)強(qiang)，通過它(ta)來(lai)實(shi)現弱電(dian)到強(qiang)電(dian)的控(kong)制(zhi)，控(kong)制(zhi)對(dui)象是電(dian)器。
