标题: 关于各种插头的接地电阻值的问题
小弟今天偶然发现一款南非大三元插头的电源线(总长1.8M)接地电阻竟然高达420m欧,所以在此想请教各位高手,各种电源插头的接地电阻有没有标准要求,分别是多少?标准规定的接地电阻不大于100m欧,这100的值包不包括器具外露的电源线及插头的阻值,请大家解惑,谢谢!

就IEC60950-2005 而言,有如下定义:
1.2.13.11
PROTECTIVE BONDING CONDUCTOR
conductor in the equipment, or a combination of conductive parts in the equipment,
connecting a main protective earthing terminal to a part of the equipment that is required to
be earthed for safety purposes

判定条件:
The resistance of the PROTECTIVE BONDING CONDUCTOR, calculated from the voltage drop,
shall not exceed 0,1 : . After the test, the PROTECTIVE BONDING CONDUCTOR shall not be
damaged.

由以上可以看出,是不包括电源线的。
