基于小波包能量分解与神经网络的断路器故障诊断研究

open access: yesGaoya dianqi
断路器在电网中肩负着控制和保护的重要任务,其结构复杂、零件繁多,容易产生潜伏性故障,加强对断路器操动机构系统潜伏性故障诊断研究,提前发现潜伏性故障,对提高断路器的运行可靠性具有重要意义。文中以ZN98型真空断路器为研究对象,搭建ZN98断路器振动加速度测试系统,以缓冲器紧固螺栓松动、挂板紧固螺栓松动、分闸线圈顶针冲程改变、合闸线圈复位弹簧失效、分闸弹簧老化、缓冲器失效、合闸弹簧固定螺栓紧死等潜伏性故障为例,基于小波包频带能量分解算法提取故障诊断特征量,并由神经网络算法进行故障识别。研究结果表明 ...
