继电(dian)器(qi)的(de)定义(yi)和基本原(yuan)理

继电器(qi)是一(yi)种电子设备(bei)，通(tong)过感应输(shu)入信号的(de)变化，自动控制输(shu)出电路的(de)状态。它由(you)一(yi)个线圈和(he)一(yi)个或多个触(chu)点组(zu)成。当线圈接通(tong)电流时，会(hui)产(chan)生(sheng)磁场，吸引触(chu)点闭(bi)合，从而接通(tong)输(shu)出电路。当线圈断电时，磁场消(xiao)失，触(chu)点在弹簧的(de)作用下断开(kai)，输(shu)出电路断开(kai)。

继电(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的作(zuo)用(yong)(yong)继电(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的作(zuo)用(yong)(yong)主要有两个方面：保(bao)(bao)护(hu)电(dian)(dian)(dian)(dian)(dian)路(lu)和(he)自动(dong)(dong)控(kong)制。保(bao)(bao)护(hu)电(dian)(dian)(dian)(dian)(dian)路(lu)：在电(dian)(dian)(dian)(dian)(dian)力系(xi)统中(zhong)，继电(dian)(dian)(dian)(dian)(dian)器(qi)(qi)被用(yong)(yong)来保(bao)(bao)护(hu)电(dian)(dian)(dian)(dian)(dian)路(lu)免(mian)受过电(dian)(dian)(dian)(dian)(dian)压、过电(dian)(dian)(dian)(dian)(dian)流等损害。当(dang)电(dian)(dian)(dian)(dian)(dian)路(lu)中(zhong)出现(xian)异常情况时(shi)，继电(dian)(dian)(dian)(dian)(dian)器(qi)(qi)会迅速动(dong)(dong)作(zuo)，切(qie)断电(dian)(dian)(dian)(dian)(dian)路(lu)，防止事故的发生。自动(dong)(dong)控(kong)制：在自动(dong)(dong)化(hua)设备中(zhong)，继电(dian)(dian)(dian)(dian)(dian)器(qi)(qi)被用(yong)(yong)来实(shi)现(xian)电(dian)(dian)(dian)(dian)(dian)路(lu)的通断控(kong)制。例如，在工业生产线上，继电(dian)(dian)(dian)(dian)(dian)器(qi)(qi)可以按照预先(xian)设定(ding)的程序控(kong)制机械臂的运动(dong)(dong)和(he)停止。湛江(jiang)通用(yong)(yong)继电(dian)(dian)(dian)(dian)(dian)器(qi)(qi)高效(xiao) 厂家爱福继电(dian)(dian)(dian)(dian)(dian)器(qi)(qi) BRD-SS-105L 来咨(zi)询！

怎(zen)样才能(neng)正确(que)地选(xuan)用(yong)继(ji)(ji)电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)呢？一是(shi)要做(zuo)到(dao)“知已知彼(bi)”，即首先必(bi)须对继(ji)(ji)电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)所控制的(de)(de)(de)对象一一被控回路(lu)的(de)(de)(de)性质、特点以(yi)及(ji)对继(ji)(ji)电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)要求等都(dou)要有周密地考察和透彻地了解。其次，对继(ji)(ji)电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)本身的(de)(de)(de)各种特性一一原(yuan)理、使用(yong)条(tiao)件(jian)、技(ji)术参(can)数(shu)、结构工艺特点以(yi)及(ji)规格型(xing)号等，做(zuo)到(dao)的(de)(de)(de)掌(zhang)握与认真分析；二是(shi)按(an)“价值工程”原(yuan)则，从先进性、合理性、可用(yong)性、经(jing)(jing)济(ji)性考虑，作到(dao)正确(que)地选(xuan)用(yong)和使用(yong)继(ji)(ji)电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)。正确(que)选(xuan)用(yong)继(ji)(ji)电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)原(yuan)则具体来讲应该是(shi)：（1）继(ji)(ji)电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)主要技(ji)术性能(neng)，如触点负荷(he)，动作时间参(can)数(shu)，机械和电(dian)(dian)(dian)(dian)气寿命等，应满足整机系(xi)统的(de)(de)(de)要求；（2）继(ji)(ji)电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)结构型(xing)式（包括安装方式）与外形(xing)尺寸应能(neng)适合使用(yong)条(tiao)件(jian)的(de)(de)(de)需(xu)要；（3）经(jing)(jing)济(ji)合理。
