    时间继电器

    时间继电器是什么?

    时间继电器是一种内置计时器的控制继电器。

    时间继电器的工作原理

    • 时间继电器是一种使用在较低的电压或较小电流的电路上,用来接通或切断较高电压、较大电流的电路的电气元件。
    • 当加入(或去掉)输入的动作信号后,时间继电器的输出电路需经过规定的准确时间才产生跳跃式变化(或触头动作)。
    • 时间继电器的主要功能是作为简单程序控制中的一种执行器件。
    • 当时间继电器接受了启动信号后开始计时,计时结束后时间继电器的工作触头进行开或合的动作,从而推动后续的电路工作。
    • 一般来说,时间继电器的延时性能在设计的范围内是可以调节的,从而方便调整延时时间的长短。
    • 单凭一只时间继电器恐怕不能做到开始延时闭合,闭合一段时间后,再断开,先实现延时闭合后延时断开,但总体上说,通过配置一定数量的时间继电器和中间继电器都是可以做到的。其特点是,自吸引线圈得到信号起至触头动作中间有一段延时。

    时间继电器的类型

    按工作原理分类:

    • 空气阻尼式时间继电器
    • 电子式时间继电器
    • 电动机式时间继电器
    • 电磁式时间继电器

    时间继电器的应用

    • 照明电路
    • 电机启动控制
    • 敏感设备
    • 安全控制
    • 传送带顺序延迟
