漏电保护器智能测试仪的研究

Study on Intelligent RCD Tester

对漏电保护器漏电动作性能参数的传统测试方法存在的问题进行了分析,提出了微机控制模拟漏电电流源的方法,并在此基础上研制了智能化漏电保护器测试仪,为漏电保护器的性能研究提供了先进的测试手段。

Several main problems in traditional means testing residual current protective de- vice(RCD)are analysed.A design method of intelligent RCD tester is presented.Using the technique of micro-processor,a different principle of testing is developed,as well as a new means of simulating residual current,which made the new RCD tester more accurate,even faster and easier to operate is introduced.
