    贴片保险丝电阻变大为什么不会熔断2020-09-28

    管状熔断器的工作原理是:过电流打破熔体上的热平衡,熔体温度上升到该金属材料的熔点时,熔体的中心部分从固体变成液体,在管上漂浮的金属材料的表面张力和重力的作用下,熔体的液体部分向两端分离而下降 贴片保险丝的动作原理也相同,但根据结构状况,金属熔液的周围被其基体部分的高分子材料和陶瓷材料牢固地包围,即使是现在熔融的金……

  • 什么是PTC过流保护器的过流保护?什么又是电路的短路保护?
    什么是PTC过流保护器的过流保护?什么又是电路的短路保护?2020-07-20

    PTC是指正温度系数,通常指具有较大正温度系数的半导体材料或元件。通常我们称PTC为正温度系数热敏电阻器,简称PTC热敏电阻器或者PTC过流保护器 PTC过流保护器是一种典型的温敏半导体电阻,当它超过一定温度(居里温度)时,电阻值随着温度的升高而逐渐增大。 电源的保护功能主要是过电压和过电流保护。那么过流保护和短路保护两者之间的关系是: 任何一种电源在发生故障时,都有可能使输出电压或输出电流失控,为了防止用户的负载受到损害,我公司的电源一般都设有过压和过流保护。有
