繼電器是(shi)一(yi)種(zhong)(zhong)(zhong)電(dian)(dian)控(kong)(kong)制器(qi)(qi)件,是(shi)當輸入(ru)量(liang)(liang)(激(ji)勵量(liang)(liang))的變化達到(dao)規定要(yao)求時,在電(dian)(dian)氣輸出電(dian)(dian)路(lu)中(zhong)使被控(kong)(kong)量(liang)(liang)發生(sheng)預定的階躍變化的一(yi)種(zhong)(zhong)(zhong)電(dian)(dian)器(qi)(qi)。固態(tai)繼(ji)(ji)電(dian)(dian)器(qi)(qi)體積小、重量(liang)(liang)輕、可(ke)靠性相對較高,無(wu)觸點,無(wu)火花(或(huo)電(dian)(dian)弧),無(wu)機械(xie)動作,品種(zhong)(zhong)(zhong)繁多,尤其適用(yong)于電(dian)(dian)子(zi)自動控(kong)(kong)制。那么,固態(tai)繼(ji)(ji)電(dian)(dian)器(qi)(qi)與普(pu)通繼(ji)(ji)電(dian)(dian)器(qi)(qi)區別是(shi)什么?下(xia)面來看看固態(tai)繼(ji)(ji)電(dian)(dian)器(qi)(qi)特點和如何使用(yong)吧!
普通繼電器
繼(ji)電器(英(ying)文名稱:relay)是(shi)(shi)一種電(dian)(dian)(dian)控(kong)(kong)制(zhi)器件(jian),是(shi)(shi)當輸(shu)(shu)入量(激勵(li)量)的(de)(de)變化達到規定要求時,在(zai)(zai)電(dian)(dian)(dian)氣輸(shu)(shu)出(chu)(chu)電(dian)(dian)(dian)路中使(shi)被控(kong)(kong)量發生預定的(de)(de)階躍變化的(de)(de)一種電(dian)(dian)(dian)器。它具(ju)有控(kong)(kong)制(zhi)系統(tong)(又稱輸(shu)(shu)入回(hui)路)和被控(kong)(kong)制(zhi)系統(tong)(又稱輸(shu)(shu)出(chu)(chu)回(hui)路)之間的(de)(de)互動關系。通常應用于(yu)自(zi)動化的(de)(de)控(kong)(kong)制(zhi)電(dian)(dian)(dian)路中,它實際上是(shi)(shi)用小(xiao)電(dian)(dian)(dian)流去控(kong)(kong)制(zhi)大電(dian)(dian)(dian)流運作的(de)(de)一種“自(zi)動開關”。故在(zai)(zai)電(dian)(dian)(dian)路中起著自(zi)動調節(jie)、安(an)全保護、轉換電(dian)(dian)(dian)路等(deng)作用。
固態繼電器
固態繼電器(qi)(SOLIDSTATERELAYS,以下簡寫成“SSR”),是(shi)一種全部由固態電子(zi)元(yuan)件(jian)(jian)組(zu)成的(de)新型無觸點(dian)開關器件(jian)(jian),它利用電子(zi)元(yuan)件(jian)(jian)(如(ru)開關三(san)極管、雙向可控硅等半導體器件)的開關特性,可達到無(wu)觸(chu)點無(wu)火花地接通(tong)和斷(duan)開電(dian)路的目的,因此又(you)被(bei)稱為(wei)“無(wu)觸(chu)點開關”。固態繼電(dian)器是一(yi)種四端有源(yuan)器件(jian),其中兩個端子為(wei)輸入控制端,另外兩端為(wei)輸出受控端.它既有(you)放大驅動作用(yong),又有(you)隔離作用(yong),很適合(he)驅動大功(gong)率開(kai)關式執行機構(gou),較之電磁繼電器可靠性更高,且(qie)無觸(chu)點、壽命長、速度快,對外(wai)界(jie)的干擾(rao)也小,已被(bei)得到廣泛應用(yong)。
固態繼電器如何使用?
“固態繼(ji)電(dian)(dian)(dian)(dian)器(qi)”一類具(ju)有(you)類似(!)傳統意義上的(de)(de)‘繼(ji)電(dian)(dian)(dian)(dian)器(qi)’功能(neng)的(de)(de)純(chun)電(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)路,這(zhe)種(zhong)(zhong)電(dian)(dian)(dian)(dian)路可(ke)(ke)以有(you)多(duo)種(zhong)(zhong)不同的(de)(de)半(ban)導體(ti)(ti)光(guang)電(dian)(dian)(dian)(dian)器(qi)件(jian)、發光(guang)器(qi)件(jian),可(ke)(ke)控硅器(qi)件(jian)和半(ban)導體(ti)(ti)二(er)極管、三極管及其組合電(dian)(dian)(dian)(dian)路組合而成,選用(yong)時(shi)一定(ding)要(yao)按實際用(yong)途作精(jing)細的(de)(de)對比選擇。它(ta)體(ti)(ti)積小、重量輕、可(ke)(ke)靠性相(xiang)對較(jiao)(jiao)高,無觸點,無火花(或電(dian)(dian)(dian)(dian)弧(hu)),無機械動(dong)作,品種(zhong)(zhong)繁多(duo),尤其適用(yong)于電(dian)(dian)(dian)(dian)子自動(dong)控制;但(dan)它(ta)的(de)(de)斷(duan)開(kai)態并(bing)非理想的(de)(de)斷(duan)開(kai)、有(you)或小或大的(de)(de)斷(duan)開(kai)態電(dian)(dian)(dian)(dian)流,過載能(neng)力較(jiao)(jiao)低,控制與(yu)被控的(de)(de)隔離度(du)(或耦合度(du))要(yao)于考慮和關注(zhu),有(you)些使(shi)用(yong)場合要(yao)與(yu)傳統繼(ji)電(dian)(dian)(dian)(dian)器(qi)比較(jiao)(jiao)成本(ben)得失(shi)。

固態繼電器和普通繼電器有什么區別?
傳統繼電器與固態繼電器的對比,由于涉及種類(lei)較(jiao)多(duo),下面以電磁繼電器與相應固態繼電器比較(jiao)說明它們的區(qu)別(bie):
1、結構(gou)區別:電(dian)(dian)磁繼電(dian)(dian)器利用(yong)輸入(ru)電(dian)(dian)路(lu)內(nei)電(dian)(dian)路(lu)在(zai)電(dian)(dian)磁鐵鐵芯與銜(xian)鐵間(jian)產生的(de)吸力作用(yong)而工(gong)作的(de);固體繼電(dian)(dian)器用(yong)電(dian)(dian)子元件履行(xing)其功能而無機械運動(dong)構(gou)件,輸入(ru)和輸出是(shi)隔離的(de)。
2、工(gong)作方式區(qu)別:電(dian)(dian)磁繼(ji)電(dian)(dian)器是(shi)利用(yong)電(dian)(dian)磁感(gan)應的(de)原理,通過電(dian)(dian)磁鐵的(de)力量來(lai)控制電(dian)(dian)路通斷,因(yin)此(ci),用(yong)直流(liu)(liu)電(dian)(dian)接線圈,觸點可以(yi)通交、直流(liu)(liu)電(dian)(dian);固態繼(ji)電(dian)(dian)器依靠(kao)半導體器件和電(dian)(dian)子元件的(de)電(dian)(dian)、磁和光特性來(lai)完成其隔離(li)和繼(ji)電(dian)(dian)切換功能(neng),因(yin)此(ci),分直流(liu)(liu)輸入-交流輸出型(xing)、直流輸入(ru)-支流(liu)輸(shu)(shu)出型(xing)、交流(liu)輸(shu)(shu)入-交(jiao)流(liu)輸出型、交(jiao)流(liu)輸入-直流輸(shu)出(chu)型。
3、工(gong)作(zuo)狀態區別:電磁繼電器利用(yong)銜鐵(tie)間產生的(de)吸力作(zuo)用(yong),通、斷電路,因此,動作(zuo)反(fan)應慢(man)、有噪聲、壽命有限;固態繼電器響應快,運行(xing)無(wu)噪音,壽命長。
4、使用(yong)環(huan)境:溫(wen)度、濕度、大氣壓力(海拔高度)、砂塵污(wu)染、化學氣體和(he)電磁干擾(rao)等(deng)要(yao)素影響(xiang)中,電磁繼電器普遍不如固態繼電器。
5、電氣性能區別:電磁繼電器與相應固態繼電器比較,前者驅動簡單,但功耗大,隔離好,短時過載耐受性好,控制大電流、大功率場合不如后者,控制動作瀕繁的電路時,壽命不如后者長。
