风扇产品质量检测案例分析

Case Studies on Safety Tests for Electric Fans

结合风扇产品的检测案例,分析了风扇安全标准中关于对可触及带电部件的防护、机械危险、机械强度、爬电距离和电气间隙等项目的要求,并总结了相关条款新旧标准的差异及容易产生错误理解的几种情况,为检测人员准确地使用风扇产品安全标准提供参考。

Combining with the testing cases of electric fans,how to correctly understand the requirements of the protection against access to live parts,mechanical hazards,mechanical strength,creepage distances and electric clearances in the standards is analyzed.The differences of relevant provisions in the previous and new standards and error-prone situations are concluded,which can provide reference for applying relative safety standards accurately.
