数字化CPS的射频电磁场辐射抗扰度试验及整改

摘要

数字化控制与保护开关(CPS)是在传统控制与保护开关的基础上,采用数字式代替传统热磁式控制与保护器而产生的新型CPS.数字化CPS中电子线路的存在需要通过射频电磁场辐射抗扰度试验.为提高数字化CPS对射频电磁场辐射的抗干扰水平,在对某个未通过试验的数字化CPS产品进行诊断分析并整改成功的基础上,提出了一些针对性的解决措施,对增强数字化CPS抗干扰水平具有指导意义.%Digital CPS is a new type of CPS; which is designed by the use of digital control and protection device to replace the thermal-magnetic one on the basis of traditional CPS. The electronic circuit in it makes it necessary to go through the radio frequency electromagnetic field radiated immunity test. Based on the diagnosis and successful rectification for a digital CPS which fails the test; we have proposed some relevant solutions which will have great significance for the enhancement of the immunity levels of digital CPS.
