    CJ20-25A交流接触器  的详细介绍
    CJ20-25A交流接触器CJ20-25用于交流50Hzz以(或60Hz).额定工作电压至660V,额定工作电流至630A的电路中,供远距离接通与分断电路之用,并可与适当的热过载继电器组合,以保护可能发生操作过负荷的电路。CJ20-25A交流接触器AC24V,AC36V,AC110V,AC220V,AC380V
    本产品符合IEC60947-4-1,GB14048.4标准。



    三、使用环境条件
    1、周围空气温度为:-5℃-+40℃,24小时内其平均值不超过+35℃;
    2、海拔高度:不超过2000m;
    3、大气条件:在+40℃时空气相对湿度不超过50%;在较低温度下可以有较高的相对湿度,*湿月的月平均*高温度不超过+25℃,该月的月平均*大相对湿度不超过90%,并考虑因温度变化发生在产品上的凝露;
    4、污染等级:3级;
    5、安装类别:(过电压类别)为Ⅲ类;
    6、安装条件:安装面与垂直面倾料度不大于±5℃;
    7、冲击振动:产品应安装和使用在无显著摇动,冲击和振动的地方。
    四、结构特点
    1、接触器的接触系统为直动式、双断点布置,CJ20-40A以上辅助触头作为独立组件安装在主触头的两侧,在电气上为分开的。CJ20-10A的辅助触头可任意组合
    见表Ⅰ。
    2、CJ20-10~25A产品既可用螺钉安装,也可用35mm标准卡轨安装。
    3、CJ20-10~16A产品采用双断点简单开断灭弧室,其余均采用多宗缝陶土灭弧罩或栅片灭弧罩,具有分断能力高、可靠性高的优点。
    4、CJ20-63~630A节电产品具有交流或直流通用两种节电模块,不仅可以派生消声节能产品或直流操作产品,而且不占用辅助触头,从而大大提高了产品的可靠性和寿命。



    结构
    接触器主要由电磁系统、触点系统、灭弧系统及其它部分组成。
    ①电磁系统:电磁系统包括电磁线圈和铁心,是接触器的重要组成部分,依靠它带动触点的闭合与断开。
    ②触点系统:触点是接触器的执行部分,包括主触点和辅助触点。主触点的作用是接通和分断主回路,控制较大的电流,而辅助触点是在控制回路中,以满足各种控制方式的要求。
    ③灭弧系统:灭弧装置用来保证触点断开电路时,产生的电弧可靠的熄灭,减少电弧对触点的损伤。为了迅速熄灭断开时的电弧,通常接触器都装有灭弧装置,一般采用半封式纵缝陶土灭弧罩,并配有强磁吹弧回路。
    ④其它部分:有绝缘外壳、弹簧、短路环、传动机构等。
    结构
    接触器主要由驱动系统、触点系统、灭弧系统及其它部分组成。
    ①驱动系统:驱动系统包括电子模块、软铁、永磁体,是永磁式接触器的重要组成部分,依靠它带动触点的闭合与断开。
    ②触点系统:触点是接触器的执行部分,包括主触点和辅助触点。主触点的作用是接通和分断主回路,控制较大的电流,而辅助触点是在控制回路中,以满足各种控制方式的要求。
    ③灭弧系统:灭弧装置用来保证触点断开电路时,产生的电弧可靠的熄灭,减少电弧对触点的损伤。为了迅速熄灭断开时的电弧,通常接触器都装有灭弧装置,一般采用半封式纵缝陶土灭弧罩,并配有强磁吹弧回路。
