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。$ O9 _! G3 v+ N* t
根据5.2.2章节有如下内容:& c% t9 {, Q: i7 M. [
Where, elsewhere in this standard, ROUTINE TESTS are required to be conducted in accordance
* p# _3 ^/ ?0 Y- ]; A- pwith 5.2.2, it is permitted to reduce the duration of the electric strength test to 1 s and to, f' ^# k4 Y) q
reduce the test voltage permitted in Table 5C, if used, by 10 %.) h* M0 Q1 n9 t" S$ o* M1 X
3 r" ]5 Q3 t8 I
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
a. T# }- s+ R) q- U) z% E+ `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。
+ ?% N7 C. e. z2 ^& @" y8 f9 ^
! B2 K' ^, N1 e& m还有在Annex U 中有如下内容:
, s: `5 y% j* _/ v) @" `- mU.3.1 Routine testing

5.2.2 of this standard, with a minimum of' D( f6 b2 w! o; r! a! H- @2 J" j
– 1 500 V a.c. r.m.s. for BASIC INSULATION or SUPPLEMENTARY INSULATION, or. E. X0 I/ G& [$ f2 z* _8 M2 E2 i
– 3 000 V a.c. r.m.s. for REINFORCED INSULATION.
5 P2 y8 ?- B' a$ F% m3 \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)。3 k+ W K b' ?
