Zhendong Ceshi yu Zhenduan为了解决水冷壁管向火面腐蚀减薄检测时聚焦探头不同摆放方式影响检测灵敏度的问题，从数值仿真与试验两方面进行分析。首先，在仿真中对传统圆柱形激励线圈径向、横向、纵向摆放方式时水冷壁管中的涡流形态及磁通密度分布进行分析，对xyz三维磁通量进行定量计算来判断检测灵敏度；其次，在试验中使用隧道磁阻传感器作为探头接收单元，分别计算每种激励线圈摆放方式下xyz三维检测灵敏度；最后，引入加权秩和比法对3种激励摆放方式进行优劣排序。结果表明，聚焦探头3种摆放方式中横向摆放具有最优的检测效果 ...

Gaoya dianqi电力设备状态评估是状态检修与运行风险预测的基础。真空断路器作为电力系统中的重要设备，为保证其安全稳定运行，需要对其状态进行准确评估。针对目前真空断路器状态评估中存在的状态指标权重单一、评估模型复杂等不足，文中以ZN63A-12型真空断路器为研究对象，提出了一种基于组合赋权和加权秩和比（WRSR）相结合的综合评估方法。首先通过选取真空断路器的4项特征状态指标，建立状态评估体系；其次采用组合赋权法计算每项指标的权重；接着根据所测数据，运用加权秩和比法对6台真空断路器进行分档排序，并对其进行状态评估；最后 ...
