摘要:
A method for inspecting an aging state of a silicone rubber composite insulating material comprises the following steps: bombarding, for multiple times and by a pulsed laser beam, selected points on a surface of a silicone rubber composite insulating material to be inspected to generate a plasma; collecting spectrum information emitted by the plasma at each bombardment, and extracting, from the collected spectrum information, a spectral property indicator of a specific constituent element of the silicone rubber composite insulating material at each bombardment; and determining aging state information of the silicone rubber composite insulating material according to the change pattern of the spectral property indicator of the specific constituent element with respect to the bombardment depth. The method enables the rapid and accurate inspection of an aging state of a silicone rubber composite insulating material, and avoids the destructive tests required in the prior art.
摘要:
A selection method for a strong wind region composite insulator based on structure parameters, and a composite insulator are disclosed. When a selection is made among a plurality of composite insulators according to the selection method, structure parameters of the composite insulators are measured first, and then the selection is made according to certain ranges of the parameters, a selected composite insulator is tested, and it is found that it may withstand strong wind climate environments where the highest wind speed reaches 50 m/s. The composite insulator is a composite insulator having corresponding structure parameters. The selection method is easy to operate and implement. When the composite insulator is applied to a strong wind region where the highest wind speed reaches 50 m/s, the problem of violent oscillation of umbrella skirts or tear of the umbrella skirts does not occur, and the composite insulator may still operate reliably.
摘要:
A selection method for a strong wind region composite insulator based on a intrinsic frequency, and a composite insulator are provided. When a selection is made among a plurality of composite insulators according to the selection method, a intrinsic frequency of a composite insulator to be selected is measured first; if the composite insulator is an unequal-diameter umbrella, the intrinsic frequency of a large umbrella skirt in the composite insulator is measured; if the composite insulator is an equal-diameter umbrella, the intrinsic frequency of any umbrella skirt in the composite insulator is measured; and then a composite insulator is selected according to the intrinsic frequency, wherein the composite insulator whose intrinsic frequency is greater than or equal to 45 Hz is selected. The composite insulator is a composite insulator having corresponding structure parameters. Study is carried out on wind-resistant performance of an insulator when applied to a strong wind region to obtain the selection method, and the method is easy to operate and implement. When the composite insulator is applied to a strong wind region where the highest wind speed reaches 50 m/s, the problem of violent oscillation of umbrella skirts or tear of the umbrella skirts does not occur, and the composite insulator may still operate reliably.
