微机保护通用平台的分析和研究

Analysis and studies on universal platform of relays

一方面对微机保护硬件平台的关键点,诸如多CPU和通讯方式的考虑、AD回路出错的检测、电源和液晶的设计、抗干扰和智能模件的考虑等做了系统的分析,另一方面对机械结构平台和抗干扰的考虑、机箱和模件尺寸的设计等也做了全面的比较,另外,对外观设计中如何既体现设备感又体现价值感提出了一些建设性的建议。

Systematic analysis and studies on either hardware platform of relays such as multi-CPU, error detection on AD channels,design of power and LCD, anti-interference and intelligence module design, or mechanical platform such as dimensions of module and case, anti-interference design are proposed. In the end of this paper, some constructive suggestions on outword appearance design are submitted.
