    • Provided is an apparatus for analyzing the state of oil-filled electrical devices. The apparatus simulates the state of an oil-filled electrical device in which copper wire wrapped in insulating paper is immersed in insulating oil. The apparatus for analyzing the state of oil-filled electrical devices includes a first paper-covered copper wire and a second paper-covered copper wire, which are adjacent to each other; a tank which holds the first and second paper-covered copper wires as well as insulating oil extracted from the oil-filled electrical device, thereby immersing the first and second paper-covered copper wires in the insulating oil; and a capacitance measurement unit which measures the capacitance between the first and second paper-covered copper wires. The first and second paper-covered copper wires includes copper wire and insulating paper wrapped therearound. The insulating paper wrapper around each copper wire includes the same material as the insulating paper in the oil-filled electrical device.
    • 提供了一种用于分析充油电气装置的状态的装置。 该装置模拟充填电气装置的状态,其中包裹绝缘纸的铜线浸入绝缘油中。 用于分析充油电气装置的状态的装置包括彼此相邻的第一纸覆铜线和第二纸包铜线; 保持第一和第二纸覆铜线的罐,以及从填充油的电气装置中提取的绝缘油,从而将第一和第二纸覆铜线浸入绝缘油中; 以及电容测量单元,其测量第一和第二纸包覆铜线之间的电容。 第一和第二纸包铜线包括铜线和包裹在其上的绝缘纸。 每根铜线周围的绝缘纸包装材料与充油电气设备中的绝缘纸材料相同。
