基于图像特征点跟踪的断路器合后即分故障分析方法

open access: yesGaoya dianqi
针对断路器弹簧机构常见的合后即分故障,文中提出了一种基于图像特征点跟踪的断路器合后即分故障分析方法。首先通过对弹簧机构传动过程的分析,确定了合后即分故障的主要分析方向。然后,基于高速摄影机数据采集平台完整记录了合闸、分闸瞬间,弹簧机构中四级分闸杠杆的传动过程,提出了基于图像特征点跟踪的弹跳幅度分析方法,通过特征点准确跟踪了四级分闸杠杆的运动轨迹,并引入了偏转角度参数准确量化了四级分闸杠杆的弹跳幅度。最后,通过对偏转角度波形的分析,判断出了导致断路器合后即分故障发生的主要原因 ...

高压断路器操动机构非侵入式多信息检测及故障诊断研究

open access: yesGaoya dianqi
高压断路器的操动机构是保障断路器可靠动作的关键部件,准确判断操动机构状态至关重要。提出了基于图像、振动、声音的非侵入式多信息检测方法,对提取的图像特征向量(分闸时间、合闸时间、分闸速度、合闸速度、分闸行程、合闸行程)、振动特征向量(特征时间点、等能量5分段能量熵)、声音特征向量(特征时间点、等能量5分段能量熵)和操动机构状态(正常、基座松动、转轴卡涩、缓冲器性能下降、拐臂润滑不足)进行了多重对应分析,找到了机构状态和相应特征向量的关联关系。提出了基于机构状态和相应特征向量关联关系的分级诊断策略 ...
