繼電器是(shi)一種(zhong)(zhong)電(dian)(dian)(dian)控(kong)制器(qi)件(jian)，是(shi)當輸(shu)入量(liang)（激勵量(liang)）的(de)變化達到規(gui)定(ding)要(yao)求時，在電(dian)(dian)(dian)氣(qi)輸(shu)出電(dian)(dian)(dian)路中(zhong)使(shi)被控(kong)量(liang)發生(sheng)預定(ding)的(de)階躍變化的(de)一種(zhong)(zhong)電(dian)(dian)(dian)器(qi)。固(gu)態繼(ji)電(dian)(dian)(dian)器(qi)體(ti)積小、重量(liang)輕(qing)、可(ke)靠性(xing)相(xiang)對較高，無(wu)觸點，無(wu)火(huo)花（或電(dian)(dian)(dian)弧），無(wu)機械動作，品種(zhong)(zhong)繁多，尤其適用于電(dian)(dian)(dian)子自(zi)動控(kong)制。那么，固(gu)態繼(ji)電(dian)(dian)(dian)器(qi)與普通繼(ji)電(dian)(dian)(dian)器(qi)區別是(shi)什么？下面來看看固(gu)態繼(ji)電(dian)(dian)(dian)器(qi)特點和如何使(shi)用吧！

普通繼電器

繼電器（英文名(ming)稱：relay）是一種電(dian)控(kong)制器(qi)件(jian)，是當輸(shu)(shu)入量（激勵量）的變化達(da)到規定要求時(shi)，在(zai)電(dian)氣輸(shu)(shu)出電(dian)路中使被控(kong)量發生預定的階躍(yue)變化的一種電(dian)器(qi)。它(ta)具(ju)有控(kong)制系(xi)統(tong)（又(you)稱輸(shu)(shu)入回路）和被控(kong)制系(xi)統(tong)（又(you)稱輸(shu)(shu)出回路）之間的互動(dong)(dong)關(guan)系(xi)。通(tong)常應用于自(zi)動(dong)(dong)化的控(kong)制電(dian)路中，它(ta)實(shi)際上是用小電(dian)流去控(kong)制大電(dian)流運作的一種“自(zi)動(dong)(dong)開關(guan)”。故在(zai)電(dian)路中起著自(zi)動(dong)(dong)調節、安全保護、轉(zhuan)換電(dian)路等作用。

固態繼電器

固(gu)態(tai)繼電器(SOLIDSTATERELAYS，以(yi)下簡(jian)寫成“SSR”)，是(shi)一種全部(bu)由固態電子(zi)元件組成的新型無觸點開關器件，它(ta)利用電子(zi)元件(如開關三(san)極管、雙(shuang)向(xiang)可控硅等半導體器件)的(de)(de)開關(guan)特性，可達到無(wu)觸點(dian)無(wu)火花(hua)地接通和斷開電(dian)路的(de)(de)目的(de)(de)，因(yin)此(ci)又被稱為“無(wu)觸點(dian)開關(guan)”。固(gu)態繼電(dian)器是一種四端(duan)有(you)源器件，其中兩個端(duan)子為輸入控制(zhi)端(duan)，另外兩端(duan)為輸出(chu)受控端(duan).它既(ji)有(you)放大驅動(dong)作用(yong)(yong)，又有(you)隔離(li)作用(yong)(yong)，很適合(he)驅動(dong)大功率開(kai)關式執行(xing)機構，較(jiao)之電(dian)磁繼電(dian)器可靠性更(geng)高，且無觸(chu)點、壽命長、速度快(kuai)，對(dui)外界的干擾(rao)也(ye)小，已被(bei)得到廣泛應用(yong)(yong)。

固態繼電器如何使用？

“固態(tai)(tai)繼(ji)電(dian)(dian)(dian)(dian)器”一類(lei)具有(you)(you)類(lei)似（！）傳(chuan)統(tong)意(yi)義(yi)上的‘繼(ji)電(dian)(dian)(dian)(dian)器’功(gong)能的純電(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)路(lu)，這種(zhong)(zhong)電(dian)(dian)(dian)(dian)路(lu)可(ke)以有(you)(you)多(duo)種(zhong)(zhong)不同(tong)的半導(dao)體光電(dian)(dian)(dian)(dian)器件、發光器件，可(ke)控硅器件和(he)半導(dao)體二極管、三極管及(ji)其組合(he)電(dian)(dian)(dian)(dian)路(lu)組合(he)而成，選用(yong)(yong)(yong)時一定要按實際(ji)用(yong)(yong)(yong)途作精細的對比(bi)選擇。它體積小、重量輕、可(ke)靠性相對較高，無觸點，無火花（或電(dian)(dian)(dian)(dian)弧(hu)），無機械(xie)動(dong)作，品種(zhong)(zhong)繁多(duo)，尤其適用(yong)(yong)(yong)于電(dian)(dian)(dian)(dian)子(zi)自動(dong)控制；但它的斷(duan)開(kai)態(tai)(tai)并非理想的斷(duan)開(kai)、有(you)(you)或小或大(da)的斷(duan)開(kai)態(tai)(tai)電(dian)(dian)(dian)(dian)流(liu)，過載能力(li)較低，控制與被(bei)控的隔離度（或耦合(he)度）要于考慮(lv)和(he)關注，有(you)(you)些使用(yong)(yong)(yong)場合(he)要與傳(chuan)統(tong)繼(ji)電(dian)(dian)(dian)(dian)器比(bi)較成本得失。

具(ju)體的使用(yong)方法與(yu)你選用(yong)的品種、類型有關(guan)，詳述困難。建議多找資(zi)料細看(kan)，比較對照，逐步熟悉使用(yong)。有具(ju)體問題再(zai)討(tao)論。

固態繼電器和普通繼電器有什么區別？

傳(chuan)統繼電器(qi)(qi)與固(gu)態繼電器(qi)(qi)的對比，由(you)于涉及種(zhong)類較多，下面以電磁(ci)繼電器(qi)(qi)與相應(ying)固(gu)態繼電器(qi)(qi)比較說明它們的區(qu)別：

1、結構(gou)(gou)區(qu)別：電(dian)(dian)磁繼電(dian)(dian)器利用(yong)輸入電(dian)(dian)路(lu)內(nei)電(dian)(dian)路(lu)在電(dian)(dian)磁鐵(tie)鐵(tie)芯與銜鐵(tie)間產生的吸力(li)作用(yong)而工作的；固體繼電(dian)(dian)器用(yong)電(dian)(dian)子(zi)元件(jian)履行其功能而無(wu)機械運動(dong)構(gou)(gou)件(jian)，輸入和輸出是隔離(li)的。

2、工作方(fang)式區別：電(dian)(dian)磁繼電(dian)(dian)器是(shi)利用(yong)電(dian)(dian)磁感應的(de)原(yuan)理，通(tong)過電(dian)(dian)磁鐵的(de)力(li)量來控制電(dian)(dian)路通(tong)斷(duan)，因(yin)此，用(yong)直流(liu)(liu)(liu)電(dian)(dian)接線圈(quan)，觸點可以通(tong)交、直流(liu)(liu)(liu)電(dian)(dian)；固(gu)態繼電(dian)(dian)器依靠半導(dao)體(ti)器件(jian)和(he)電(dian)(dian)子元件(jian)的(de)電(dian)(dian)、磁和(he)光(guang)特性來完成其隔離(li)和(he)繼電(dian)(dian)切換功能，因(yin)此，分直流(liu)(liu)(liu)輸入-交流(liu)輸出型、直流(liu)輸入-支流輸出型、交(jiao)流輸入(ru)-交流輸(shu)(shu)出型(xing)、交流輸(shu)(shu)入(ru)-直流輸出型。

3、工作(zuo)狀態(tai)區別(bie)：電(dian)磁繼電(dian)器利用銜鐵間產生的吸(xi)力作(zuo)用，通、斷電(dian)路，因此，動作(zuo)反應(ying)慢(man)、有(you)噪聲、壽命有(you)限(xian)；固(gu)態(tai)繼電(dian)器響(xiang)應(ying)快(kuai)，運行無噪音，壽命長。

4、使用環境：溫度、濕度、大氣壓力(海拔高度)、砂塵(chen)污染、化學氣(qi)體和電(dian)(dian)磁干擾等要素影響(xiang)中，電(dian)(dian)磁繼電(dian)(dian)器普遍不如(ru)固態繼電(dian)(dian)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。
