如题所示,关于IEC60950-1:2005中Routine Test 耐压测试时间与电压设定,我本人从标准中一直没看到有比较明确的说法。
* \& B/ z" K# w根据5.2.2章节有如下内容:; b0 E0 N; n3 j7 x/ [, h- ]; L) `
Where, elsewhere in this standard, ROUTINE TESTS are required to be conducted in accordance
. P4 ^6 r" y. r6 mwith 5.2.2, it is permitted to reduce the duration of the electric strength test to 1 s and to a* h; L! B8 E7 N g+ n1 U1 t
reduce the test voltage permitted in Table 5C, if used, by 10 %.7 A9 N: P7 m; ~+ a& G+ H" @' |' h
8 y9 h) A9 I9 p% q2 j: [$ E+ O f% ~
这个内容说时间可以减少到1秒,电压可以根据表C来进行,但是说得很模糊,尤其是
3 ^* v* Z! H t6 `1 ~2 ^Where, elsewhere 这两个单词,不好理解到底是哪里。是否也包括LN对地?我们产线上打的地方就是LN对地。6 z& m0 R6 t% a* H, L
8 S# f' ?9 [- Q# s0 |/ ^还有在Annex U 中有如下内容:6 U* F" A* b6 V, f. X
U.3.1 Routine testing

: Q9 A& T) o: O N1 w, J( ~& N但是我一直觉得Annex U 只适用于Insulated winding wires for use without interleaved insulation,而不是用于我们产线上的位置(我们产线一般就打LN对地)。

希望各位可以引出标准进行讨论。 |
