固態繼電器(qi)（solid state relay）簡稱ssr，是一種由集成電路和分立元器(qi)件組合而(er)成的----

“一(yi)體化”無(wu)觸點電(dian)子開關(guan)器(qi)(qi)件(jian)，它采(cai)用電(dian)子線路實(shi)現繼電(dian)器(qi)(qi)的功(gong)能，依靠光(guang)電(dian)耦(ou)合器(qi)(qi)（或其(qi)他耦(ou)合方式）實(shi)現控(kong)制系(xi)統(tong)（輸入回路）與被控(kong)制系(xi)統(tong)（輸出回路）之(zhi)間的電(dian)氣(qi)隔離。由于(yu)在開關(guan)過(guo)程中無(wu)機械(xie)接(jie)觸部件(jian)，因此具有控(kong)制功(gong)率小(xiao)、可靠性(xing)高、壽命長(chang)、無(wu)噪聲、無(wu)火花、無(wu)電(dian)磁(ci)干擾(rao)、開關(guan)速度快和工作頻率高等突出優(you)點固態(tai)繼電(dian)器(qi)(qi)自1974年問世(shi)以來，已在許多自動化控(kong)制裝置中取代了電(dian)磁(ci)繼電(dian)器(qi)(qi)，并且廣泛用于(yu)電(dian)磁(ci)繼電(dian)器(qi)(qi)無(wu)法應(ying)用的領(ling)域(yu)。

結構及原理

常(chang)(chang)用(yong)(yong)固(gu)態繼(ji)電(dian)器(qi)(qi)(qi)幾(ji)乎都(dou)是模塊化的(de)(de)(de)(de)四端(duan)有源器(qi)(qi)(qi)件(jian)(jian)，其中兩(liang)端(duan)為輸(shu)(shu)入控(kong)制端(duan)，另外兩(liang)端(duan)為輸(shu)(shu)出受控(kong)端(duan)，其基本構成如圖(tu)所示(shi)。器(qi)(qi)(qi)件(jian)(jian)中多采用(yong)(yong)光(guang)電(dian)耦合(he)器(qi)(qi)(qi)實現輸(shu)(shu)入與輸(shu)(shu)出之間(jian)的(de)(de)(de)(de)電(dian)氣隔離。輸(shu)(shu)出受控(kong)端(duan)利用(yong)(yong)開關三極管(guan)、雙向晶閘管(guan)等半導體器(qi)(qi)(qi)件(jian)(jian)的(de)(de)(de)(de)開關特性(xing)，實現無觸點、無火(huo)花(hua)地接(jie)通和(he)斷(duan)開外接(jie)控(kong)制電(dian)路(lu)的(de)(de)(de)(de)目的(de)(de)(de)(de)。整個器(qi)(qi)(qi)件(jian)(jian)無可動部件(jian)(jian)及觸點，可實現相當于常(chang)(chang)用(yong)(yong)電(dian)磁(ci)繼(ji)電(dian)器(qi)(qi)(qi)一樣的(de)(de)(de)(de)功能。

圖常(chang)用固態(tai)繼電器(qi)構成圖

普通固態(tai)(tai)繼電(dian)器的(de)內部等效電(dian)路如圖(tu)所示。當給固態(tai)(tai)繼電(dian)器的(de)輸(shu)入端(duan)in接上合適的(de)控制信號時，其(qi)輸(shu)出端(duan)out就會從關(guan)(guan)斷(duan)狀(zhuang)態(tai)(tai)變為導通狀(zhuang)態(tai)(tai)；控制信號撤消后，輸(shu)出端(duan)out 恢復(fu)關(guan)(guan)斷(duan)狀(zhuang)態(tai)(tai)。從而實(shi)現了對輸(shu)出端(duan)所接負載(zai)(zai)（注(zhu)意負載(zai)(zai)應串入輸(shu)出端(duan)回(hui)路）電(dian)源(yuan)的(de)無觸(chu)點(dian)“開(kai)”或(huo)“關(guan)(guan)”自動控制。

固(gu)(gu)(gu)態(tai)(tai)繼電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)按(an)輸出端(duan)(duan)(duan)極性的不同，可(ke)分(fen)(fen)為直(zhi)流式和交(jiao)流式兩大(da)類。直(zhi)流固(gu)(gu)(gu)態(tai)(tai)繼電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)（dc-ssr）的電(dian)(dian)(dian)(dian)(dian)路(lu)原理參見圖（a），其(qi)控制電(dian)(dian)(dian)(dian)(dian)壓由(you)輸入端(duan)(duan)(duan)in輸入，通過光(guang)電(dian)(dian)(dian)(dian)(dian)耦合(he)器(qi)(qi)(qi)將(jiang)控制信號耦合(he)至接(jie)收(shou)電(dian)(dian)(dian)(dian)(dian)路(lu)，經放大(da)處(chu)理后驅動開(kai)關(guan)三極管(guan)vt導通。顯然，直(zhi)流固(gu)(gu)(gu)態(tai)(tai)繼電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的輸出端(duan)(duan)(duan)out在接(jie)入被控電(dian)(dian)(dian)(dian)(dian)路(lu)回路(lu)中時(shi)，是有正(zheng)、負(fu)極之(zhi)分(fen)(fen)的。交(jiao)流固(gu)(gu)(gu)態(tai)(tai)繼電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)（ac-ssr）的電(dian)(dian)(dian)(dian)(dian)路(lu)原理參見圖（b），與直(zhi)流固(gu)(gu)(gu)態(tai)(tai)繼電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)不同的是，其(qi)開(kai)關(guan)元件采用(yong)了雙向晶閘管(guan)vs 或其(qi)他(ta)交(jiao)流開(kai)關(guan)，因(yin)此它的輸出端(duan)(duan)(duan)out無正(zheng)、負(fu)極之(zhi)分(fen)(fen)，可(ke)以控制交(jiao)流回路(lu)的通斷。

由于固態(tai)繼電(dian)(dian)(dian)(dian)器(qi)(qi)的(de)輸入(ru)端和輸出端之間采用了成熟可(ke)靠的(de)光電(dian)(dian)(dian)(dian)隔(ge)離(li)等技術，這使(shi)得所接控(kong)制弱電(dian)(dian)(dian)(dian)和被(bei)控(kong)強電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)氣上完全隔(ge)離(li)，因(yin)此從(cong)各種(zhong)弱電(dian)(dian)(dian)(dian)設備輸出的(de)信號(hao)(hao)可(ke)以(yi)直接加(jia)在固態(tai)繼電(dian)(dian)(dian)(dian)器(qi)(qi)的(de)輸入(ru)控(kong)制端上，無(wu)(wu)需另(ling)外(wai)的(de)保護電(dian)(dian)(dian)(dian)路等。固態(tai)繼電(dian)(dian)(dian)(dian)器(qi)(qi)和傳(chuan)統的(de)電(dian)(dian)(dian)(dian)磁繼電(dian)(dian)(dian)(dian)器(qi)(qi)相比(bi)較(jiao)，具有的(de)優點是∶工(gong)作(zuo)可(ke)靠、壽命長、無(wu)(wu)噪聲、無(wu)(wu)火花、無(wu)(wu)電(dian)(dian)(dian)(dian)磁干(gan)擾、開關速(su)度快、抗干(gan)擾能(neng)力強、體積小、耐沖擊、耐振動、防(fang)爆、防(fang)潮、防(fang)腐蝕(shi)，能(neng)與ttl、dtl、htl等邏輯電(dian)(dian)(dian)(dian)路兼(jian)容，可(ke)以(yi)通過微小的(de)控(kong)制信號(hao)(hao)實現(xian)直接驅動大(da)電(dian)(dian)(dian)(dian)流負載的(de)目的(de)。正(zheng)因(yin)為如此，固態(tai)繼電(dian)(dian)(dian)(dian)器(qi)(qi)在很多領域(yu)正(zheng)逐漸取代電(dian)(dian)(dian)(dian)磁繼電(dian)(dian)(dian)(dian)器(qi)(qi)。

但固(gu)態繼電(dian)器也存在(zai)一(yi)(yi)些缺點，主要是輸出端在(zai)導通時存在(zai)一(yi)(yi)定的電(dian)壓降，即本身有功(gong)耗，需采取相應的散熱措施在(zai)斷開時存在(zai)一(yi)(yi)定的漏電(dian)流。另外，固(gu)態繼電(dian)器的控(kong)制狀態比較單一(yi)(yi)、過(guo)載能(neng)力差，并且(qie)直(zhi)流繼電(dian)器和交流繼電(dian)器不能(neng)通用。

④輸出(chu)電(dian)(dian)(dian)(dian)(dian)壓降(jiang)/輸出(chu)漏電(dian)(dian)(dian)(dian)(dian)流。輸出(chu)電(dian)(dian)(dian)(dian)(dian)壓降(jiang)是指固態(tai)(tai)繼電(dian)(dian)(dian)(dian)(dian)器處于(yu)導通狀態(tai)(tai)時，在(zai)額定工作(zuo)電(dian)(dian)(dian)(dian)(dian)流下所測得的輸出(chu)端電(dian)(dian)(dian)(dian)(dian)壓值(zhi)。輸出(chu)漏電(dian)(dian)(dian)(dian)(dian)流是指固態(tai)(tai)繼電(dian)(dian)(dian)(dian)(dian)器處于(yu)關(guan)斷狀態(tai)(tai)時，在(zai)輸出(chu)端施加額定輸出(chu)電(dian)(dian)(dian)(dian)(dian)壓的條(tiao)件(jian)下所測得的流經(jing)負(fu)載的電(dian)(dian)(dian)(dian)(dian)流值(zhi)。顯然(ran)，衡量一個(ge)固態(tai)(tai)繼電(dian)(dian)(dian)(dian)(dian)器的優劣，它的輸出(chu)電(dian)(dian)(dian)(dian)(dian)壓降(jiang)和(he)輸出(chu)漏電(dian)(dian)(dian)(dian)(dian)流均應越(yue)小越(yue)好(hao)。

⑤浪(lang)涌電流。這(zhe)是指固態繼電器處(chu)于(yu)導通(tong)狀態

時，輸出端所能承受、且不致造成器件永久性損壞的(de)非重復最大浪涌（或過載）電流。交流

固態(tai)繼電(dian)器的(de)(de)浪漫(man)電(dian)流(liu)為(wei)額定(ding)工(gong)作(zuo)電(dian)流(liu)的(de)(de)5～10倍（1個周期），直流(liu)產品為(wei)額定(ding)工(gong)作(zuo)電(dian)流(liu)的(de)(de)1.5~5倍（1s）。

目前(qian)(qian)，國內(nei)外(wai)固態繼電(dian)(dian)器的(de)(de)型(xing)號(hao)命(ming)名(ming)方法五(wu)花八門(men)，即(ji)使是國內(nei)各廠家(jia)的(de)(de)產(chan)品(pin)(pin)(pin)，往往在型(xing)號(hao)命(ming)名(ming)及(ji)規格標(biao)(biao)志上(shang)也(ye)存在很(hen)大(da)差(cha)異。例如(ru)：北(bei)京靈(ling)通電(dian)(dian)子有(you)(you)限公(gong)司生產(chan)的(de)(de)“靈(ling)通”系列固態繼電(dian)(dian)器，其(qi)(qi)第(di)1部(bu)分(fen)用字母(mu)(mu)“s”表(biao)(biao)(biao)示(shi)(shi)普通交流(liu)固態繼電(dian)(dian)器(大(da)功率(lv)產(chan)品(pin)(pin)(pin)不標(biao)(biao)字母(mu)(mu)),“d”表(biao)(biao)(biao)示(shi)(shi)普通直流(liu)固態繼電(dian)(dian)器，并(bing)且“s”或(huo)“d”前(qian)(qian)面(mian)加有(you)(you)“h”表(biao)(biao)(biao)示(shi)(shi)該(gai)產(chan)品(pin)(pin)(pin)為“增(zeng)強型(xing)”;第(di)2部(bu)分(fen)用字母(mu)(mu)“a”表(biao)(biao)(biao)示(shi)(shi)控制(zhi)信號(hao)為“交流(liu)電(dian)(dian)”,如(ru)無此字母(mu)(mu)則(ze)表(biao)(biao)(biao)示(shi)(shi)為“直流(liu)電(dian)(dian)”;第(di)3部(bu)分(fen)用數字表(biao)(biao)(biao)示(shi)(shi)工作(zuo)電(dian)(dian)壓，其(qi)(qi)中“2”表(biao)(biao)(biao)示(shi)(shi)“24～240v”,“3”表(biao)(biao)(biao)示(shi)(shi)“40～420v”,“6”表(biao)(biao)(biao)示(shi)(shi)“45～660v”;第(di)4部(bu)分(fen)用數字表(biao)(biao)(biao)示(shi)(shi)額定(ding)工作(zuo)電(dian)(dian)流(liu)，單位(wei)(wei)a(不標(biao)(biao)出);第(di)5部(bu)分(fen)用字母(mu)(mu)表(biao)(biao)(biao)示(shi)(shi)產(chan)品(pin)(pin)(pin)類型(xing)，其(qi)(qi)中“z”代(dai)(dai)表(biao)(biao)(biao)過零型(xing)，“p”代(dai)(dai)表(biao)(biao)(biao)“隨機(調相(xiang))型(xing)”,直流(liu)輸出的(de)(de)產(chan)品(pin)(pin)(pin)此位(wei)(wei)無字母(mu)(mu)；第(di)6部(bu)分(fen)用字母(mu)(mu)表(biao)(biao)(biao)示(shi)(shi)外(wai)形(xing)，常(chang)見字母(mu)(mu)有(you)(you)“k”“l”“w”“f”等幾種。表(biao)(biao)(biao)給(gei)出了幾種常(chang)用固態繼電(dian)(dian)器的(de)(de)型(xing)號(hao)及(ji)性能(neng)參數，僅供參考。

表幾種(zhong)常用固態(tai)繼電(dian)器的性(xing)能參數

固態繼(ji)電(dian)器的(de)型號(hao)中包含了(le)產(chan)品的(de)主(zhu)要特征和重要參數信息，由(you)于各(ge)廠(chang)(chang)家(jia)對(dui)產(chan)品型號(hao)命名(ming)(ming)的(de)方法不統一(yi)，給使(shi)用(yong)者帶來了(le)一(yi)定的(de)不便。這就要求(qiu)使(shi)用(yong)者在選(xuan)用(yong)固態繼(ji)電(dian)器時(shi)，必須認(ren)真查閱廠(chang)(chang)家(jia)說明書，弄(nong)清楚(chu)產(chan)品的(de)命名(ming)(ming)方法，弄(nong)清楚(chu)主(zhu)要電(dian)氣(qi)參數，確保正(zheng)確合理地(di)使(shi)用(yong)。

產品標識

常(chang)用(yong)固態(tai)(tai)(tai)繼(ji)(ji)(ji)電(dian)器(qi)都(dou)是四端(duan)(duan)器(qi)件，其(qi)外殼除了標(biao)(biao)出(chu)(chu)圖(tu)(tu)(a)所(suo)示的(de)產品名稱(有時用(yong)字母(mu)“ssr”表示)、型號、廠家銘牌(pai)外，還(huan)將引(yin)(yin)(yin)腳(jiao)(jiao)功能直接標(biao)(biao)示在(zai)外殼上，如(ru)圖(tu)(tu)(b)所(suo)示。體積較(jiao)大的(de)大功率固態(tai)(tai)(tai)繼(ji)(ji)(ji)電(dian)器(qi)，不僅標(biao)(biao)志出(chu)(chu)了引(yin)(yin)(yin)腳(jiao)(jiao)功能，而(er)且還(huan)將輸入電(dian)壓范(fan)圍或輸入電(dian)流、額(e)定輸出(chu)(chu)電(dian)壓和(he)額(e)定工作電(dian)流等參數(shu)直接標(biao)(biao)示在(zai)相應的(de)引(yin)(yin)(yin)腳(jiao)(jiao)附近，如(ru)圖(tu)(tu)29-5(c)所(suo)示。可見，盡管固態(tai)(tai)(tai)繼(ji)(ji)(ji)電(dian)器(qi)(尤其(qi)是微(wei)、超(chao)小型產品)的(de)輸入端(duan)(duan)和(he)輸出(chu)(chu)端(duan)(duan)在(zai)排列順序上沒有什(shen)么規律，但其(qi)引(yin)(yin)(yin)腳(jiao)(jiao)識(shi)別起來還(huan)是比較(jiao)容易的(de)。

有些固(gu)態繼(ji)(ji)電器(qi)(qi)的(de)外殼上面還開(kai)出了一(yi)個小圓孔(kong)，并露(lu)出紅(hong)色發光(guang)二極管(guan)的(de)管(guan)帽，該發光(guang)二極管(guan)多系輸入端工作狀態指(zhi)示燈，這(zhe)是普通電磁繼(ji)(ji)電器(qi)(qi)所(suo)(suo)沒有的(de)，如(ru)圖(d)所(suo)(suo)示。如(ru)果需(xu)要了解更詳細的(de)參數和性能特點等，需(xu)要查閱廠家產品說明書或(huo)固(gu)態繼(ji)(ji)電器(qi)(qi)產品手冊。

電路符號

固態(tai)繼電器(qi)在電路圖中的(de)(de)表示符(fu)號(hao)(hao)見圖。注意：圖形符(fu)號(hao)(hao)各引腳旁邊(bian)(方框(kuang)內、外(wai)均可)分(fen)別標出(chu)電極性(xing)符(fu)號(hao)(hao)，輸(shu)入(ru)端(duan)和輸(shu)出(chu)端(duan)按慣(guan)例不(bu)要畫(hua)在同一邊(bian)或相鄰的(de)(de)一邊(bian)上(shang)。當同一個電路圖中出(chu)現多個固態(tai)繼電器(qi)時，可按習(xi)慣(guan)在文字符(fu)號(hao)(hao)后面(mian)加上(shang)數字編(bian)號(hao)(hao)，以示區別。
