    人民電器Jqx-63f繼電器的特點及使用說明

    2021/5/31 9:15:34      點擊:
    產品特點:
        電磁繼電器是一種自動電氣開關,當給了一個輸入量,如電磁光或熱信號時,他就能自動切換被控制電路,使之產生一個變,當輸入量降至一程度時,它又恢復到初始狀態,使被控電路又跳到原來狀態。

        廣泛應用于機械設備、通訊設備、辦公室設備、家用設備輸入與輸出電路之間的信號轉換,增加輸出電路重復信號,切換不同電壓或電流,符留輸出信號,閉鎖電路,提供遙控等現代化自動領域。

    繼電器的選擇及使用:
        繼電器是重要的電子基礎元件,它有自己的性能和工藝特點。在使用中,這些性能和特點都能直接影響著控制系統的工作質量和技術經濟指標。因此對用戶來講,首先是根據整機線路要求正確選用適合的繼電器,其次是正確使用繼電器。否則,一是不能充分發揮繼電器性能的作用和維持固有可靠性,甚至造成浪費;二是不能保證控制系統的正常工作,從而危及設備、系統的可靠性。
    正確選用繼電器的原則:
    1、繼電器的技術性能,如觸點負荷、動作時間及電氣參數、機械和電氣壽命等,應完全滿足整機系統所提出的要求。
    2、繼電器的結構型式(包括安裝方式)與外形尺寸應能適合使用條件要求。
    3、根據工作環境條件合理選用繼電器,如:環境溫度及濕度、振動與沖擊、輻照及電磁干擾等,應不影響繼電器的使用要求。
