摘要
从在线监测系统的电源、信号传输、PCB布局分区、布线等方面入手,介绍了提高在线监测系统抗电磁干扰的方法。实验证明,采用该方法设计的在线监测系统,抗电磁干扰性能得到较大提高,已经通过了国家高压电器质量监督检验中心电磁兼容性严酷度等级3级标准的试验。
In this paper, the methods used to improve anti-electromagnetic interference ability was introduced, especially focus on the power supply system, signal transmission, PCB subarea layout, and PCB connection layout. By using these methods presented in this paper, the anti- electromagnetic interference ability of on-line monitoring system was improved greatly, and had passed 3 degree EMC standard test.
