摘　　要：提出一种基于光电传感器的新型高压断路器电寿命在线监测系统,断路器的开断电流信号由Rogowski线圈电流传感器进行采集,保证了测量的高精度;采集的信号经光缆传到主控室光电转换与信号处理单元,通过加权累计法计算断路器的电寿命,从而得出剩余寿命,并根据阈值给出告警提示信息,从而减少过早或不必要的停电试验和检修,可显著提高电力系统的可靠性和经济性。This paper presents a new type of life-line monitoring system of high-voltage circuit breaker electrical endurance based on photoelectric. The circuit breaker＇ s breaking current signal from the Rogowski coil current sensor is collected to ensure the measurement precision.＇ The signal is transmitted by the fiber optic cable to the main control room where the signal photoelectric conversion and signal and monitoring unit, calculated electrical circuit breaker life by weighting the accumulated, so as to arrive remaining life, and based on threshold alarms, tips are given to reduce the premature or unnecessary testing and repair. The system can significantly improve power system reliability and economy.
