电压互感器一次设备检修状态识别逻辑研究

The study of voltage transformer primary equipment repair status recognition logic

分析了传统变电站数据采集方式，指出传统变电站的电压并列切换模式实现检修状态面对的问题，设计出一种能够运用于电压互感器检修状态识别逻辑装置，该逻辑装置将传统变电站的母线电压互感器检修状态转换成三位的二进制输出量，便于设备识别，适合低成本开发装置，具有工程应用价值。

This paper analysed the traditional substation data collection methods and pointed out the problems of maintenance status using tied traditional substation voltage switch mode. The paper proposed a voltage transformer maintenance status recognition logic device, which would convert the maintenance status of the bus bar voltage transformer of traditional substation to a three digit binary out put. This led easy device identification and low - cost for practical applications.
