关于各种插头的接地电阻值的问题

yang1933

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。
