Disqualification analysis of minitype hair dryer

本论文介绍了小巧型电吹风两种基本的工作原理,并给出了一种类型的电吹风的完整电路,分析其在安规试验中常见的几种不合格项,主要有非正常试验不合格,爬电距离、电气间隙不合格。具体的整改措施有:选用合适自复位热断路器、外壳用耐火耐热型塑料、合理布置导线、电源线连接改进设计等。

The paper introduced two basic principle of Hair Dryer and provided a type of intact circuit and analyzed its several disqualifications in safety test. The main disqualifications come from： abnormal test, creepage and clearance distance. This paper brings forward improvement measure： selecting suitable serf-resetting thermal cut-out , using resisting fire-plastic in crust, laying wire appropriately , changing connecting in power supply design.
