摘要
随着智能化配电网的发展,断路器的健康状态保障着电力系统的稳定运行。断路器在运行中易出现机械故障,因此,准确、及时地发现故障种类,有针对性的状态检修可以避免电力故障带来的安全问题。断路器的故障诊断可以从以下方面来总结:获取信号、特征提取、故障分类和状态检修。信息和传感器技术的进步、智能算法的应用改变了以往的专家系统诊断方式。文章所提方法给断路器的故障识别提供参考依据,最后,讨论了电力设备断路器的故障诊断与在线监测未来发展方向。
With the development of intelligent distribution networks,the health status of circuit breakers ensured the stable operation of the power system.Circuit breakers are prone to mechanical failures during operation,and accurate and timely detection of fault types and targeted maintenance can avoid property safety caused by power loss.The fault diagnosis of circuit breakers is summarized from three aspects:signal acquisition,feature extraction,fault classification and condition maintenance.Advances in information and sensor technology and the application of intelligent algorithms have changed the previous expert system diagnosis.The methods proposed in the article are summarized to provide frame for fault identification of circuit breakers.Finally,the future development direction of fault diagnosis and online monitoring of power equipment circuit breakers is discussed.
