在变电站的微机保护系统中，显示器作为监控装置的主要设备，其性能的好坏不仅直接影响到系统的在线监视，而且可能会产生微机保护系统中最令人头疼的电磁干扰问题。从现在普遍使用的彩色显示器的工作原理来看，其开关电源电路、行输出电路由于工作在高频或高压状态，随着显示?
In substation microcomputer protection system, the monitor as the main equipment of the monitoring device, its performance not only directly affects the system online monitoring, but also may produce the computer protection system in the most troublesome electromagnetic interference problem. From the now commonly used color monitor works, the switching power supply circuit, the output circuit due to work in high-frequency or high-pressure state, with the display?
