7 j0 d: ~0 u8 n6 }5 ?probel b?看下标准吧,可见灼热元件是probel 41
% }- S" w8 ]1 ~' b没错,你看的应该是防触电里面的要求,确实是说不用probe B而是用Probe 41。但我的问题是爬电距离的问题。你可以看看标准定义:- f# @9 h+ B5 W. _4 l5 ~
爬电距离:shortest distance along the surface of insulation between two conductive parts or between a
5 p% `1 W2 o7 U6 Zconductive part and the accessible surface! X- o9 i8 P# j6 s2 O
可接触表面:part or surface that can be touched by means of test probe B of IEC 61032, and if the part or R% T3 I7 I) G0 `4 N
surface is metal, any conductive part connected to it
' k, Z. N/ e' z# v8 l单从定义来讲并未说是用probe 41来判定可接触表面的界定。 |
