摘要
地铁直流断路器在线录波装置通过采集直流断路器动作时的电流、电压、分合闸及位置反馈信号形成录波数据,对波形的关键点和形态特征进行自动分析,输出关键参数,反映断路器的机械特性和电气特性,并将数据存储在历史数据库中。该装置的开发实现了对断路器性能的在线监测、历史数据统计、故障预警及寿命预估等功能。
The online recording devices for subway DC circuit breaker are able to realize the automatic analysis on the key points and morphological characteristics of waveform by collection of current, voltage, tripping, closing and position feedback signals of DC circuit breaker, and output the key parameters, reflect the mechanical and electrical characteristics of the circuit breaker, and store the data into the historical database. The device＇s development realizes the functions of online monitoring, historical data statistics, failure alarm and service life prediction for circuit breakers
