60590里面2.1.1.5能量危险有些疑问?希望帮忙解答,非常谢谢

你的问题,IEC 60950-1已经给出了答案.

以下引用于EN 60950-1-2006

危险能量等级:

1.2.8.10
HAZARDOUS ENERGY LEVEL
available power level of 240 VA or more, having a duration of 60 s or more, or a stored energy level of 20 J or more (for example, from one or more capacitors), at a potential of 2 V or more.


危险能量的危害

0.2.2 Energy related hazards
Injury or fire may result from a short-circuit between adjacent poles of high current supplies or
high capacitance circuits, causing:
− burns;
− arcing;
− ejection of molten metal.

至于危险能量等级的划分,标准并没有给出.我查了一下,相关标准并未发现这个概念.或许,并不存在这个说法...

我们CSA将举行一个关于60950第二版标准的研讨会,详情请看本论坛的“60950第二版标准”.

thanks very much
