繼電器(qi)的定義和基本(ben)原理

繼電(dian)器是一種電(dian)子設備，通(tong)過感應(ying)輸(shu)(shu)入信號的變(bian)化，自動控制輸(shu)(shu)出(chu)(chu)電(dian)路的狀(zhuang)態。它由(you)一個線圈和(he)一個或多個觸(chu)點(dian)組成。當線圈接通(tong)電(dian)流時，會產生磁場，吸引觸(chu)點(dian)閉合，從(cong)而接通(tong)輸(shu)(shu)出(chu)(chu)電(dian)路。當線圈斷(duan)電(dian)時，磁場消失，觸(chu)點(dian)在彈簧的作用下斷(duan)開，輸(shu)(shu)出(chu)(chu)電(dian)路斷(duan)開。

繼(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)的作(zuo)用繼(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)的作(zuo)用主(zhu)要有兩(liang)個方面：保護電(dian)(dian)(dian)(dian)路(lu)和(he)自(zi)動控制。保護電(dian)(dian)(dian)(dian)路(lu)：在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)力系統中(zhong)，繼(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)被用來保護電(dian)(dian)(dian)(dian)路(lu)免(mian)受過(guo)電(dian)(dian)(dian)(dian)壓、過(guo)電(dian)(dian)(dian)(dian)流(liu)等(deng)損害(hai)。當電(dian)(dian)(dian)(dian)路(lu)中(zhong)出現(xian)異常情(qing)況時，繼(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)會(hui)迅速動作(zuo)，切(qie)斷電(dian)(dian)(dian)(dian)路(lu)，防止事故(gu)的發生。自(zi)動控制：在(zai)(zai)(zai)自(zi)動化設備中(zhong)，繼(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)被用來實現(xian)電(dian)(dian)(dian)(dian)路(lu)的通斷控制。例如，在(zai)(zai)(zai)工業生產線上，繼(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)可以(yi)按照(zhao)預先設定的程序控制機械(xie)臂的運動和(he)停(ting)止。湛江(jiang)通用繼(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)高(gao)效 廠家(jia)愛福(fu)繼(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi) BRD-SS-105L 來咨詢！

怎樣才能正(zheng)(zheng)確(que)地(di)選(xuan)用(yong)(yong)繼(ji)電(dian)(dian)器呢？一(yi)是要(yao)(yao)做到“知(zhi)已知(zhi)彼(bi)”，即首先(xian)(xian)必須對繼(ji)電(dian)(dian)器所(suo)控制的(de)對象一(yi)一(yi)被控回路(lu)的(de)性(xing)質、特(te)點(dian)以及對繼(ji)電(dian)(dian)器的(de)要(yao)(yao)求等都要(yao)(yao)有周密地(di)考(kao)察和透徹地(di)了(le)解。其次，對繼(ji)電(dian)(dian)器本身的(de)各種特(te)性(xing)一(yi)一(yi)原(yuan)理(li)、使用(yong)(yong)條件(jian)、技(ji)術參(can)(can)數(shu)、結構工藝特(te)點(dian)以及規格型號等，做到的(de)掌握與(yu)認真分(fen)析(xi)；二是按(an)“價(jia)值工程”原(yuan)則，從先(xian)(xian)進(jin)性(xing)、合理(li)性(xing)、可(ke)用(yong)(yong)性(xing)、經濟性(xing)考(kao)慮，作(zuo)到正(zheng)(zheng)確(que)地(di)選(xuan)用(yong)(yong)和使用(yong)(yong)繼(ji)電(dian)(dian)器。正(zheng)(zheng)確(que)選(xuan)用(yong)(yong)繼(ji)電(dian)(dian)器的(de)原(yuan)則具(ju)體(ti)來講應該是：（1）繼(ji)電(dian)(dian)器的(de)主(zhu)要(yao)(yao)技(ji)術性(xing)能，如觸點(dian)負荷，動(dong)作(zuo)時(shi)間參(can)(can)數(shu)，機(ji)(ji)械和電(dian)(dian)氣壽命(ming)等，應滿足整(zheng)機(ji)(ji)系(xi)統的(de)要(yao)(yao)求；（2）繼(ji)電(dian)(dian)器的(de)結構型式(shi)(shi)（包括(kuo)安裝方式(shi)(shi)）與(yu)外形尺寸應能適合使用(yong)(yong)條件(jian)的(de)需(xu)要(yao)(yao)；（3）經濟合理(li)。
