Abstract

The assessment of equipment condition is essential for the condition-based maintenance. In this paper the use of decision matrices for condition determination of high-voltage equipment is discussed. This requires a "rating" realization of the general decision matrix with adapted key rating criteria describing the equipment under examination. After forming the rating matrix, it is shown how ageing and maintenance can be integrated into the proposed approach. With the integration of ageing and maintenance the rating matrix can yield forecasts for the expected condition of the equipment in the future. The proposed method is then used in order to determine the condition of a high-voltage circuit breaker. It must be emphasized that the term "condition" used henceforth does not merely reflect the technical condition of the equipment, but it also includes economical and other aspects. It should also be noticed that, in this paper, the degradation state (rather than the actual condition state) is calculated. This approach offers specific advantages, especially when the effects of ageing or maintenance are being taken into account. Combined with a failure mode, effect and criticality analysis (FMECA), the method can be used in order to calculate the risk associated with the specific piece of equipment.
额定矩阵在高压设备状态评估中的应用
设备状态评估是设备状态维修的重要内容。本文讨论了决策矩阵在高压设备状态确定中的应用。这需要通用决策矩阵的“评级”实现,其中包含描述被检查设备的适应性关键评级标准。在形成评级矩阵后,展示了如何将老化和维护集成到所提出的方法中。将老化与维修相结合,可以对设备未来的预期状态进行预测。然后使用所提出的方法来确定高压断路器的状态。必须强调的是,今后使用的“条件”一词不仅反映设备的技术条件,而且还包括经济和其他方面。还需要注意的是,本文计算的是退化状态(而不是实际状态)。这种方法具有特殊的优势,特别是当考虑到老化或维护的影响时。结合失效模式、影响和临界性分析(FMECA),该方法可用于计算与特定设备相关的风险。
