ARM9 / DSP-Based High Voltage Circuit Breaker On-line Monitoring Technology

针对高压断路器在线工作时高电压、大电流而不易使用传感器监测一次线路电流、电压的情况,提供了一种高压真空断路器在线监测方法及一种在线监测装置。首先介绍了该系统的框架结构与功能模块,并详细分析了系统的硬件电路。随后介绍了一种数据处理方法,该方法可实现对高压断路器动触头的行程数据的一系列滤波与修正,同时可计算行程曲线上分合闸换位点,最终得到所需要的关键数据,并将得到的工作状态曲线传至显示终端。

For a certain of not easy to use the sensor to monitor the current and voltage of the primary side since the high voltage and current when the circuit breaker is proper on-line working,a method and device of the high voltage vacuum circuit breaker on-line monitoring is designed in this paper.First of all,the frame structure and functional module of the system are built in this paper where the hardware circuits are also analyzed in detail.Soon afterwards,a data processing method is put forward which can realize the filter and correction of the moving contact of stroke when using the high voltaae circuit breaker.
