繼電器的定義和基本原(yuan)理

繼(ji)電(dian)器是(shi)一種(zhong)電(dian)子設備，通(tong)過感應輸入信(xin)號(hao)的(de)(de)變化，自動(dong)控制輸出(chu)電(dian)路的(de)(de)狀態。它(ta)由一個線圈和一個或多個觸(chu)點組成。當(dang)線圈接通(tong)電(dian)流時，會(hui)產生磁場(chang)，吸引(yin)觸(chu)點閉合，從而接通(tong)輸出(chu)電(dian)路。當(dang)線圈斷電(dian)時，磁場(chang)消(xiao)失，觸(chu)點在彈簧的(de)(de)作用下斷開，輸出(chu)電(dian)路斷開。

繼(ji)電(dian)(dian)器(qi)(qi)(qi)的(de)(de)作(zuo)用(yong)(yong)繼(ji)電(dian)(dian)器(qi)(qi)(qi)的(de)(de)作(zuo)用(yong)(yong)主要有(you)兩(liang)個方面：保(bao)護(hu)電(dian)(dian)路(lu)(lu)(lu)(lu)和自(zi)動(dong)控制(zhi)。保(bao)護(hu)電(dian)(dian)路(lu)(lu)(lu)(lu)：在(zai)電(dian)(dian)力系統中，繼(ji)電(dian)(dian)器(qi)(qi)(qi)被(bei)用(yong)(yong)來保(bao)護(hu)電(dian)(dian)路(lu)(lu)(lu)(lu)免(mian)受過電(dian)(dian)壓、過電(dian)(dian)流等(deng)損害(hai)。當電(dian)(dian)路(lu)(lu)(lu)(lu)中出現異常情(qing)況時，繼(ji)電(dian)(dian)器(qi)(qi)(qi)會(hui)迅速動(dong)作(zuo)，切斷電(dian)(dian)路(lu)(lu)(lu)(lu)，防止事故(gu)的(de)(de)發生。自(zi)動(dong)控制(zhi)：在(zai)自(zi)動(dong)化設(she)備中，繼(ji)電(dian)(dian)器(qi)(qi)(qi)被(bei)用(yong)(yong)來實現電(dian)(dian)路(lu)(lu)(lu)(lu)的(de)(de)通斷控制(zhi)。例如，在(zai)工業生產(chan)線上，繼(ji)電(dian)(dian)器(qi)(qi)(qi)可以按照預先設(she)定的(de)(de)程序控制(zhi)機械臂的(de)(de)運動(dong)和停止。湛江通用(yong)(yong)繼(ji)電(dian)(dian)器(qi)(qi)(qi)高效 廠(chang)家愛福繼(ji)電(dian)(dian)器(qi)(qi)(qi) BRD-SS-105L 來咨詢！
