家用电器泄漏电流测试问题研究

STUDY ON LEAKAGE CURRENT MEASUREMENT

本文在Dalziel进行的人体对电流感知特性的研究基础上引入了人体相对感知程度概念,得到了人体相对感知程度曲线,通过与RC并联网络的电阻分流系数幅频特性曲线比较,引申出人体相对感知程度的解析逼近。在明确人体等效感知电流的含义后,给出了其数值逼近。最后,解释了泄漏电流测试电路输入阻抗的作用,并指出了本研究的意义。

In this paper,body leakage current relative sensitivity is drawn into and body leakage current relative sensitivity curve is aquired from Dalziel's reserching conclusion in body sensory current. Comparing this curve to the resistance current division ratio amptitude characteristic curve in RC parallel circuit, an analytical function approach to the body leakage current relative sensitivity is led out. After body equivalent sensory current is drawn into, its numerical approximation is led out. Then, the function of input impedence of leakage current measuring circuit is given out. And the significance of the study is pointed.
