三角插座,为什么地线插片长

因为安全插座的接地脚眼内有片安全挡片（防止小孩把东西误插入插孔内导致触电事故），一定要先把挡片顶开，才可以使三爪插头插入插座！这种设计是最安全的,

保证地线最先'

最牢固'

最大的接触面,

来释放用电器的漏电电流因为三脚插头的地线那一脚是保护地的作用，它大也就意味着横截面大，阻值变小，也可降低接触电阻U=IR

。从而保证设备产生故障的时候将漏电电流充分的引入大地 .

那是为了安全而做的,

插入时先接地线,

拔时后切地线,

这样才符合国家安全标准.

这是为了安全，地线插片长一些，是在使用时，地线能够先于火线零线插入。在拔出时，地线最后从插座拔出。
