泄漏电流测试仪人体阻抗模拟电路的探讨
资料介绍
泄漏电流是电气设备安全性能中最重要的参数,其测量原理是使用人体阻抗模拟电路来模拟人体接触电气设备时的触电情况,通过模拟,最终可以确定该电气设备泄漏电流的大小。主要从人体阻抗的构成和人体对泄漏电流的反应两个方面给出了3种对应的人体阻抗模拟电路,并分析了其各自的特点,对于泄漏电流测试仪的使用和校准工作有着比较深远的现实意义。
Leakage current is the most important parameter of the safety performance of electrical equipment. Its measuring principle is to use human impedance analog circuit to simulate the electric shock when the human body touches the electrical equipment. Through simulation, the leakage current of the electrical equipment can be determined. According to the composition of human body impedance and the human body's reponse to leakage current, three corresponding human body impedance analog circuits are given, and their respective characteristics are analyzed, which has far-researching practical significance for the use and calibration of leakage current tester.
