摘要
不同的安全标准对电气间隙和爬电距离有不同要求,其限值的求法和结果不尽相同.今以一开关电源电路为例,介绍在不同标准下如何根据工作电压情况对最小电气间隙和爬电距离值进行确定.
Different safety standards have different requirements for the clearance and creepage distance of the limits of different calculation methods and results. In this paper, a switch power circuit is given as an example to introduce how to confirm the minimum clearance and creepage distance with working voltage on different safety standards.
