目前,笔者在一家电子公司检验一种机械电子式电能表时发现该公司有些仪表存在严重的电磁兼容问题。随着科学技术的迅猛发展,各类电子、电器产品日新月异,由于使用的频率越来越宽、功率加大、脉冲窄化、运算速度加快等因素,使人们生活的电磁环境愈加复杂化。在这种情况下,电子电器产品能否正常工作并满足电磁兼容的要求,已经成为一个非常重要的问题。解决电磁兼容的核心问题:(1)设法减少产品自身产生的电磁辐射和提高抗电磁干扰的能力,可采取吸 At present, when I test a mechanical electronic watt-hour meter at an electronics company, I found that some of the company’s instruments have serious electromagnetic compatibility issues. With the rapid development of science and technology, various types of electronic and electrical products are changing with each passing day. As the frequency of use is getting wider and wider, the power is increased, the pulse is narrowed, the operation speed is accelerated and other factors make the electromagnetic environment of people’s life more complicated. Under such circumstances, it has become a very important issue whether electrical and electronic products can work normally and meet the requirements of electromagnetic compatibility. Solve the core issues of electromagnetic compatibility: (1) try to reduce the electromagnetic radiation generated by the product itself and improve anti-electromagnetic interference ability, can take the suction
