! s2 l/ k2 w1 T$ bprobel b?看下标准吧,可见灼热元件是probel 41 ' z: ^0 V E/ O0 a/ D/ b" F5 m
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:
8 ~" c* J3 ^2 k$ ?" a$ c爬电距离:shortest distance along the surface of insulation between two conductive parts or between a% r, v; i- x5 A. D
conductive part and the accessible surface
/ A& b2 K9 m0 q7 O' F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/ x, V' C2 D# u2 B
surface is metal, any conductive part connected to it# R! G* c. @, a J
单从定义来讲并未说是用probe 41来判定可接触表面的界定。 |
