Abstract

Of late, the permanent magnetic actuator has been used widely in the vacuum circuit breaker. The permanent magnet mechanism explored in this paper adopts the NdFeB permanent magnet. An important indicator of its reliability is the mechanical life of the vacuum circuit breakers (VCBs). In this study, 12 KV permanent magnet-operated VCBs have been tested for their mechanical fidelity. With the degradation failure following the Gaussian process and the traumatic failure of the Weibull distribution, the competition failure model has been established by considering the correlation between the two failure modes. The model parameter estimation was determined using the EM algorithm. Eventually, the reliability of the model was attained. This paper evaluates the results of different methods have been compared and analysed, which further proved that the method proposed in this paper had better evaluation accuracy and certain specific value for engineering application.
基于竞争失效模型的永磁材料作动真空断路器可靠性分析
近年来,永磁执行机构在真空断路器中得到了广泛的应用。本文探讨的永磁机构采用钕铁硼永磁体。其可靠性的一个重要指标是真空断路器(VCB)的机械寿命。在这项研究中,对12KV永磁体操作的VCB的机械保真度进行了测试。考虑到服从高斯过程的退化失效和威布尔分布的创伤性失效,通过考虑两种失效模式之间的相关性,建立了竞争失效模型。使用EM算法来确定模型参数估计。最终达到了模型的可靠性。本文对不同方法的评价结果进行了比较分析,进一步证明了本文提出的方法具有较好的评价精度和一定的工程应用价值。
