摘要
针对变电站微机保护装置研制过程中遇到的现场电磁波辐射干扰、电源高频谐波干扰、装置内部信号传导干扰、开关噪声等电磁干扰问题,从装置屏蔽体设计、电源与接地系统设计、干扰滤波及隔离、PCB板设计和软件抗干扰5个方面介绍和实施了抗电磁干扰的解决方法,使装置获得了良好的电磁兼容性和优越的工作性能。
To solve electromagnetic interference questions like field radiated interference, high frequency power interference, signal conducted interference, on-off noise etc. encountered in the manufacture of micro-computer protector in transformer substation, five resist electromagnetic interference methods like the design of screen body, power and ground, filter and insulation, printed circuit board and software were introduced. These methods make the protector get good electromagnetic compatibility and prominent work performance.
