摘要： A power equipment and method for providing the same are disclosed. The power equipment comprises a high voltage part (14, 24, 34), a low voltage part (16, 26, 36), and an insulation oil adapted to impregnate the high voltage part (14, 24, 34) and insulate the high voltage part (14, 24, 34) from the low voltage part (16, 26, 36). The insulation oil is partially filled with polymer particles (5) with a lower thermal expansion coefficient than the insulation oil. The degree of expansion of the insulation medium can be reduced in a cost-effective way.

摘要： Provided are a method and apparatus for defect pre-warning of a power device. The method comprises processing one or more measurement data regarding one or more components of the power device based on predetermined severity criteria, to obtain one or more severities of one or more monitoring indexes related to one or more defects of the one or more components (S201); determining one or more weights of the one or more monitoring indexes with respect to the one or more defects, based on effectiveness of the one or more monitoring indexes for the one or more defects (S202); and estimating a defect probability that at least one of the one or more components has each of at least one of the one or more defects, based on the one or more severities and the one or more weights (S203). It achieves more reliable defect probability estimation; it further estimates defective component probability and/or device healthy. Based on the reliable information, it facilitates to arrange the maintenance before defects involve into a fault and assess a risk of power device operation and control, thereby improving reliability of the power device.
