标准UL 60950-1 第2.10.2.1章节 g)条有对工作电压的确定做说明:
: N9 g2 e' v, p) ^The WORKING VOLTAGE between any point in the PRIMARY CIRCUIT and earth, and between
4 k2 E4 n, S* w/ iany point in the PRIMARY CIRCUIT and a SECONDARY CIRCUIT, shall be assumed to be the. O6 D' L( X1 r
greater of the following:
8 V! c6 `. \1 l" y2 o' [– the RATED VOLTAGE or the upper voltage of the RATED VOLTAGE RANGE; and
. }* {+ x, A5 \– the measured voltage.% V0 I' {( v# j' m' b; |$ E
是额定电压或电压范围的上限值和实际测试的工作电压做比较,较大者为此测试点的工作电压。所以一次侧到接地金属至少为额定电压或额定电压范围的上限值。然后根据这个情况取值再去查表。 |
