请教UL 1029 放电灯镇流器距离要求
这里有一个放电灯镇流器,金属外壳是接地的.测量PCB边缘的焊点点到金属外壳的电压有400V左右.那么这个点到金属外壳的距离是不是要求有9.5mm呢.
UL 对于接地的外壳也要有这么大的要求么?
请教高人. 根据UL 1029的：
15.1 Spacings through air (clearance) and over surface of insulating material (creepage distance) between:
a) Uninsulated live parts of opposite polarity, and
b) An uninsulated live part and a dead metal part that may be grounded, a metal part exposed to contact by persons, or a metal surface on which the ballast is mounted as intended, shall be not less than indicated in Table 15.1.
确实是这个要求，没错。 谢谢。了解了。
