摘要
随着电子技术的蓬勃发展,电子产品的种类繁多,其结构也更加复杂。电子产品的广泛应用,其安全性关乎着每一位消费者。接触电流和保护导体电流是评估电击防护措施和电气安全事故调查研究的重要参数。文章根据GB 4943.1-2022的要求进行测试,探究开关电源在不同测试条件下的结果,其测试结果与理论数值一致,说明在不同频率下,人体阻抗模型具有一定的合理性。
With the rapid development of electronic technology,there are many kinds of electronic products and their structures are more complex.The safety of electronic products,which are widely used,concerns every consumer.Contact current and protective conductor current are the important parameter in the evaluation of shock protection measures and investigation of electrical safety accident.This article is based on GB 4943.1-2022 to test,the results of switching power supply under different test conditions are explored through the test,and the test results are consistent with the theoretical values.it shows that the human impedance model is reasonable at different frequencies.
