Abstract

Aiming at the problem of electrical life prediction of AC contactor individual, considering that characteristic information and degradation trend of different life stages are different, a comprehensive electrical life analysis method is proposed. First, based on uncertainty reasoning, initial electrical life is qualitatively evaluated to realize an early warning for contactor with poor performance. Secondly, real-time monitoring of performance degradation inflection point is used to realize the determination of degradation stage. With degradation stage matching mechanism, the quantitative prediction of remaining useful electrical life is realized based on performance inflection point and Elman neural network, thus forming an effective monitoring of the operation state in full life cycle. It is verified by experiment that the proposed method can accurately evaluate initial life grade and predict remaining useful life after performance inflection point. Compared with other methods, the information of electrical life for contactor individual can be accurately and comprehensively obtained. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.

接触器单体电气寿命评估与预测方法研究

针对交流接触器单体电气寿命预测问题，考虑到不同寿命阶段的特征信息和劣化趋势不同，提出了一种综合电气寿命分析方法。首先，基于不确定性推理，对初始电气寿命进行定性评估，实现对性能不良接触器的预警。其次，通过对性能退化拐点的实时监测，实现对退化阶段的判断。通过退化阶段匹配机制，基于性能拐点和 Elman 神经网络实现剩余有用电寿命的定量预测，从而形成对全寿命周期运行状态的有效监控。实验验证了所提出的方法能准确评估初始寿命等级并预测性能拐点后的剩余使用寿命。与其他方法相比，可以准确、全面地获取接触器个体的电气寿命信息。© 2024 日本电气工程师学会和 Wiley Periodicals LLC。
