| 摘 要： | 分析了常规的指数衰减振荡波建模方法的实质和不足,提出了基于断路器振动信号传播中畸变现象的改进型建模方法。在频域内建立了自学习的优化建模策略,并通过实例分析初步验证了该优化策略的正确性和可行性。该建模方法为高压断路器机械状态的监测与诊断提供了新的理论依据和技术手段。

| Abstract: | The essence and deficiency of the conventional modelling method based on exponentially damped oscillatory waves are analyzed, and an improved modelling method based on the distortion phenomenon in propagation of the vibration signals of circuit breakers is proposed. A self-study optimization modelling strategy is set up in the frequency domain, and its validity and feasibility are preliminarily verified by an example. The modelling method shows a new theoretical basis and techniques for monitoring and diagnosing of the mechanical condition of high voltage circuit breakers. |
