继(ji)电器的(de)定义和基本原理

继电(dian)器是一种电(dian)子(zi)设备，通过感应输入(ru)信(xin)号的(de)变化，自动控制(zhi)输出电(dian)路的(de)状态。它由一个线(xian)圈和一个或多个触点组成。当线(xian)圈接通电(dian)流时，会(hui)产生(sheng)磁(ci)场(chang)，吸引(yin)触点闭合，从(cong)而接通输出电(dian)路。当线(xian)圈断电(dian)时，磁(ci)场(chang)消失(shi)，触点在(zai)弹簧的(de)作用下断开，输出电(dian)路断开。

继(ji)(ji)电(dian)(dian)(dian)(dian)(dian)器(qi)的(de)作用继(ji)(ji)电(dian)(dian)(dian)(dian)(dian)器(qi)的(de)作用主要有两个方面：保护(hu)(hu)电(dian)(dian)(dian)(dian)(dian)路(lu)(lu)和自动控制(zhi)。保护(hu)(hu)电(dian)(dian)(dian)(dian)(dian)路(lu)(lu)：在电(dian)(dian)(dian)(dian)(dian)力系统中(zhong)，继(ji)(ji)电(dian)(dian)(dian)(dian)(dian)器(qi)被用来(lai)保护(hu)(hu)电(dian)(dian)(dian)(dian)(dian)路(lu)(lu)免受过电(dian)(dian)(dian)(dian)(dian)压、过电(dian)(dian)(dian)(dian)(dian)流等损害。当电(dian)(dian)(dian)(dian)(dian)路(lu)(lu)中(zhong)出(chu)现异(yi)常(chang)情况(kuang)时，继(ji)(ji)电(dian)(dian)(dian)(dian)(dian)器(qi)会迅速(su)动作，切断(duan)电(dian)(dian)(dian)(dian)(dian)路(lu)(lu)，防(fang)止事故的(de)发生。自动控制(zhi)：在自动化(hua)设备中(zhong)，继(ji)(ji)电(dian)(dian)(dian)(dian)(dian)器(qi)被用来(lai)实现电(dian)(dian)(dian)(dian)(dian)路(lu)(lu)的(de)通断(duan)控制(zhi)。例如，在工业生产线上，继(ji)(ji)电(dian)(dian)(dian)(dian)(dian)器(qi)可以(yi)按照预先(xian)设定的(de)程(cheng)序控制(zhi)机(ji)械臂的(de)运(yun)动和停(ting)止。湛江通用继(ji)(ji)电(dian)(dian)(dian)(dian)(dian)器(qi)高效(xiao) 厂家爱福(fu)继(ji)(ji)电(dian)(dian)(dian)(dian)(dian)器(qi) BRD-SS-105L 来(lai)咨(zi)询！
