  • Publication number: 20150255194
    Abstract: 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.

  • Publication number: 20150136470
    Abstract: 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.
