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:3 g7 U: l( D) J# v
The WORKING VOLTAGE between any point in the PRIMARY CIRCUIT and earth, and between
H: g5 {: p! dany point in the PRIMARY CIRCUIT and a SECONDARY CIRCUIT, shall be assumed to be the
?# u* b9 M9 _! Fgreater of the following:4 `/ T [) p! T* Q8 F9 o- C
– the RATED VOLTAGE or the upper voltage of the RATED VOLTAGE RANGE; and
" B& K7 [' E6 j* z: S0 C– the measured voltage.
& G+ t" q' ~$ \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。 |
