基于分合闸线圈信号的断路器状态在线监测系统设计
Design of online monitoring system for breaker status based on closing coils signal
摘要
Abstract
Aiming at the research status and deficiencies of online monitoring technology for high voltage circuit breaker, an online monitoring system for high voltage circuit breaker status based on the current signal of the closing coil is provided. The hardware circuits and online monitoring soft were designed. The system can realize collecting,converting,filtering,amplifying and analyzing the real-time current signals quickly,and also can calculate a lot of parameters such as the close-open time,close-open velocity,switching path,close-open path and overshoot distance,which can judge the types of action of the high voltage circuit breaker,and the monitoring results can be displayed on the PC monitor interface. Experiment and actual operation shows that the system has the advantages of better real-time,fully data monitoring,high reliability and high anti-disturbance.关键词
