SELECTION METHOD FOR STRONG WIND REGION COMPOSITE INSULATOR BASED ON INTRINSIC FREQUENCY, AND COMPOSITE INSULATOR |
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. |
