In order to realize comprehensive,real-time and continuous monitoring of circuit breaker status in complex scenes,an automatic detection system of circuit breaker fault based on wireless sensing technology is designed.The current,voltage,temperature,vibration and other state information of circuit breaker are collected by wireless sensing technology,and the fault characteristics of circuit breaker are extracted by fine composite multi-scale scattered entropy algorithm,and a typical fault characteristic library of circuit breaker is constructed according to historical fault types.Calculate the similarity between actual fault characteristics and typical fault characteristics,and complete the fault de-tection of circuit breaker.The experimental results show that the system can effectively collect the state information of circuit breakers in real-time,with complete information transmission,effectively extract the fault characteristics of circuit breakers,and accurately and automatically detect the faults of circuit breakers.
