摘要

机械性能损坏是引起断路器故障的主导因素

因而针对断路器的机械故障诊断研究具有非常重要的理论价值与实际意义。为了实现对断路器机械故障的有效诊断

文中提出一种基于高斯径向基函数的识别分类算法。该算法将信号整个有效频段内的归一化能谱作为特征向量

其中每一个频率分量对应着一个特征维度

而且不再涉及时频域分割

所以无需考虑分割依据及合理性等问题

因此具有更强的适应性。另外

所构建的故障诊断系统具有参数修正优化功能

因此诊断准确率能够随着测试数据的不断增加而得到提高。最后通过实验研究验证了文中所提出断路器机械故障诊断算法的有效性。

Abstract

The mechanical performance damage is the dominant factor causing the fault of circuit breaker;therefore

the study on mechanical fault diagnosis for circuit breaker has very important theoretical value and practical significance. For achieving effective diagnosis for the mechanical fault of circuit breaker

a kind of identification and classification algorithm based on Gaussian radial basis function is proposed in this paper. This algorithm takes the normalized energy spectrum in the whole effective band of signal as the feature vector

in which every frequency component corresponds to one characteristic dimension without involving time frequency domain segmentation.Therefore

it has stronger adaptability without considering segmentation foundation and rationality. In addition

the constructed fault diagnosis system has a parameter correction and optimization function. Finally

the effectiveness of the mechanical fault diagnosis algorithm of the circuit breaker proposed in this paper is verified by the study of experiment.
