摘要
随着电子产品在生活中的广泛应用,其辐射安全亦逐渐成为大众关注的焦点.为确保人身健康、设备安全和电磁环境,以及保护用户和消费者的利益,需对辐射发射不合格的产品进行整改.通过对电子产品辐射发射超标原因的分析,可以得出产品辐射发射超标通常是由干扰源、干扰耦合路径和敏感设备3 个方面因素造成的.本文依据国家相关辐射安全标准,运用先进的电磁兼容性原理及屏蔽效应理论,定位电子设备辐射源,分析其辐射特性,并采取相应措施,使被测产品的辐射发射值降低到规定限值以内.本文提出当前辐射发射整改的三大方向为屏蔽、滤波、隔离,为相关研究进一步发展提供参考.
Abstract
With the wide application of electronic products in life,its radiation safety has gradually become the focus of public attention.In order to ensure personal health,equipment safety and electromagnetic environment,as well as to protect the interests of users and consumers,it is necessary to rectify the products with unqualified radiation emission.Through the analysis of the reasons for the excessive radiation emission of electronic products,it can be concluded that the excessive radiation emission of products is usually caused by three factors,interference source,interference coupling path and sensitive equipment.According to relevant national radiation safety standards,this paper used advanced electromagnetic compatibility principles and shielding effect theory to locate the radiation source of electronic equipment,analyzed its radiation characteristics,and took corresponding measures to reduce the radiation emission value of the tested product to within the specified limit,put forward the three major directions for radiation emission rectification at present were shielding,filtering,and isolation,which providing further reference for related research.
