机箱漏电该怎么办?相信很多朋友身体碰到了机箱的时候,感到了一股明显的电流,是不是觉得是电脑漏电了呢?其实出现这种情况有两种原因,接下来我们一起看看吧。
电脑主机箱漏电也算日常生活中常见的故障之一了,主机箱原本是为了保护电脑各部件的作用,怎么会反而成了电的帮凶呢?其实不以为然,接下去你看了就知道了。
电脑主机箱漏电
一、空气中湿度较大,从而造成机箱的静电电压过高,导致我们身体接触到时产生触电感觉。
机箱(图1)
二、机器内部元件碰撞导致的,就是主板零部件间安装不牢固,在晃动的时候导致线路发生碰撞产生漏电。

三、电源,电源没有连接稳定,往往是最容易出问题的,或者电源线出现故障,因为线路老化导致
机箱(图3)
四、主板,一般手碰到主板上会出现强烈的触电感,这个通常是主板内部走线出现问题

五、机箱本体漏电,机箱外壳若是金属材料的,内部主板或线路和机箱接触就会造成导电的情况,所以漏电的情况才会出现

六、最后一种是机箱带电。为防止来源于微机外部的电磁干扰,在 电源220V输入回路装有滤波电路。该滤波电路由两个电容串联组成,两个电容的中点与电源外壳直接连接。大多数情况下电压小于12V,这种情况是是不会对人体造成损伤,当然也不能长期接触

以上就是电脑机箱漏电的原因,希望你看了之后会有帮助。
