采用双CPU的分布式断路器在线监测装置研究

Research of Dual-CPU Distributed Circuit Breaker Monitoring Equipment

本文提出一种采用双CPU的分布式断路器在线监测装置,对断路器的电寿命、机械特性和温度进行实时监测,并详细介绍系统的硬件结构和软件程序。对断路器进行阈值预设定,通过主要状态辨识对断路器进行在线测量,并与在日常检查中记录断路器正常运行时的状态辨识量进行比较,判断断路器的正常、预警、故障、急停等信息。

This paper presents a dual - CPU distributed circuit breaker monitoring system, real - time monitoring of temperature, electri- cal life of the circuit breaker, mechanical properties, and the details of the hardware structure and software. Threshold set on the circuit breakers and normal operation of the ＂fingerprint wave＂for storage, which compare collecting data with storage waveform and set circuit breaker threshold. Given the state of the breaker in the normal, warning, failure and emergency stop.
