继电器上发生的故障中， 多半是接点接触性问题所引起的， 根据负载条件不同， 其故障内容也有所不同。负载条件可大致分为微小能源· 水平（小功率电路） 、

中间能源· 水平、高能源· 水平。
微小能源· 水平， 严格地来讲称为机械性接触电路， 是指不会因热、放电等接点的接触状态而发生变化的负载条件。但是在实际情况中， 即使施加某种程度的电

压， 由于接触状态不变化， 因此包含其负载条件在内， 进行定义。对接触状态不产生影响的界限电压称为接点软化电压（Softening Voltage）， 银为0.09V、金

为 0.08V、铂为0.25V、钨为0.6V。
中间能源· 水平是指引起轻度放电现象的负载条件， 从接点软化电压到电弧开始放电的电压。电弧开始放电的电压， 银为12V、金为15V、铂为17.5V、钨为15V，

10%的钯银合金为11V。
高能源· 水平是指电弧开始放电电压以上的电压。
有关接点的特殊问题
接点根据使用方法会发生特殊现象。

继电器线圈在非工作状态下暴露在高温、高湿的环境中， 而且线圈卷线和铁芯等其他金属之间有电位差时，如果它们之间的绝缘不充分， 两者间流通的离子化电

流， 将可能腐蚀线圈上所卷的铜线。与在金属上进行电镀的作用相同，通过酸、碱等，将可促进该作用。在以往的继电器中， 往往忽视这种现象， 但是最近在

卷轴材方面开发出了特性较好的塑料， 而且卷线的绝缘材也开发出了聚氨酯类、聚脂、聚酰胺、特氟龙等特性优良的材料， 减少了一部分危险性。要防止电气腐

蚀，应避免在高温、高湿中保管及使用。在电路构成方面应注意开关的位置， 使其不在卷线上施加+电位， 需要考虑+接地等。

线圈温度和动作
继电器温度一发生变化， 继电器接点弹簧的弹性、摩擦状态、线圈电阻等也发生变化。但是， 其中对动作时间产生较大影响的是线圈电阻的变化。已经在继电器

的动作原理部分对这一点进行了说明。电磁铁的动作与电流有关。在直流电磁铁下， 电流可表示为以下公式。

    i ： 线圈电流
    R ： 线圈电阻
    E ： 线圈外加电压
    ι ： 线圈的时间常数L/R
    t ： 从电压外加时经过的时间
在这里线圈温度若是上升， 如前面所述， 线圈电阻在0.4％/℃下变大， 线圈时间常数（L/R） 的R （线圈直流电阻） 也变大，因此接点的等待时间就缩短， 动

作时间也在变快的方向上产生作用。相反， 线圈电阻的增加引起线圈电流的减少， 因此在电压操作的继电器中， 动作时间反而变长。下图表示关于电压操作和

电流操作各自动作时间相对于线圈温度而发生的变化。
如大型继电器那样动作时间要花费数10ms的继电器， 即使温度变化， 也不会发生较大变化， 在10ms以下的小型继电器中可以看到温度引起的变化的倾向。
