BDYD-J4aDll型交流电压变送器的抗干扰设计

摘要

介绍了BDYD-J4aD11型交流电压变送器的抗干扰设计.通过实例设计分析了大规模电子器件在电子设备中应用越来越多的今天,如何合理的在电路中应用接地设计、电磁屏蔽等抗干扰手段减少外界对电压变送器的电磁干扰,提高产品的电磁兼容能力.另外,还通过实例介绍了如何通过合理设计电路,抑制电磁干扰干扰源以及各种干扰的传递途径,提供了几种常用金属材料的屏蔽性能对比值和实际PCB设计板图.%This paper discusses the anti-jamming design of BDYD - J4aD11 AC voltage transmitter. Instance design for large-scale electronic devices more and more applications in electronic devices today, how reasonable application of ground in the circuit design,electromagnetic shielding, anti-jamming means to reduce the external electromagnetic interference voltage transmitter, improve product electromagnetic compatibility. In addition, this paper also introduced through examples how the rational design of circuits to suppress electromagnetic interference sources of interference and interference pathway, and provide shielding performance of several commonly used metal materials ratio and the actual PCB design board diagram for the reader reference.
