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。
4 t( G' n1 v" D0 p. [根据5.2.2章节有如下内容:
( F6 Y' k6 \6 ?* |/ pWhere, elsewhere in this standard, ROUTINE TESTS are required to be conducted in accordance
5 y* e0 v0 |% t! J7 cwith 5.2.2, it is permitted to reduce the duration of the electric strength test to 1 s and to ], w6 ^! e* E/ V+ }6 C
reduce the test voltage permitted in Table 5C, if used, by 10 %.
( }; I: r' y% ]) z# Q
3 v$ F3 N! Y {% s. 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% S+ O6 r% j) l M1 S( F: ]
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。! s# `+ s9 A1 u" p

还有在Annex U 中有如下内容:
" Z' Z, p( ^. ` B, uU.3.1 Routine testing
. l3 }) Y: j+ q- F4 R# b6 A, tThe test voltage for ROUTINE TESTING shall be the appropriate test voltage in accordance with8 P3 ^* U7 n9 T! E" Z7 y* Q5 K
5.2.2 of this standard, with a minimum of
% c, s# h. T1 Q: m- H2 L– 1 500 V a.c. r.m.s. for BASIC INSULATION or SUPPLEMENTARY INSULATION, or
5 z2 o# D+ r- Q: `( {% w7 x– 3 000 V a.c. r.m.s. for REINFORCED INSULATION.
) W2 O% w0 r2 l/ q. `/ j5 H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)。' h! W6 Q1 Y2 O! [4 L3 W

希望各位可以引出标准进行讨论。 |
