      人民电器Jqx-63f继电器的特点及使用说明

      2021/5/31 9:15:34      点击:
      产品特点:
          电磁继电器是一种自动电气开关,当给了一个输入量,如电磁光或热信号时,他就能自动切换被控制电路,使之产生一个变,当输入量降至一程度时,它又恢复到初始状态,使被控电路又跳到原来状态。

          广泛应用于机械设备、通讯设备、办公室设备、家用设备输入与输出电路之间的信号转换,增加输出电路重复信号,切换不同电压或电流,符留输出信号,闭锁电路,提供遥控等现代化自动领域。

      继电器的选择及使用:
          继电器是重要的电子基础元件,它有自己的性能和工艺特点。在使用中,这些性能和特点都能直接影响着控制系统的工作质量和技术经济指标。因此对用户来讲,首先是根据整机线路要求正确选用适合的继电器,其次是正确使用继电器。否则,一是不能充分发挥继电器性能的作用和维持固有可靠性,甚至造成浪费;二是不能保证控制系统的正常工作,从而危及设备、系统的可靠性。
      正确选用继电器的原则:
      1、继电器的技术性能,如触点负荷、动作时间及电气参数、机械和电气寿命等,应完全满足整机系统所提出的要求。
      2、继电器的结构型式(包括安装方式)与外形尺寸应能适合使用条件要求。
      3、根据工作环境条件合理选用继电器,如:环境温度及湿度、振动与冲击、辐照及电磁干扰等,应不影响继电器的使用要求。
