Composite insulators umbrella of its electric field distribution on

    Composite insulators umbrella of its electric field distribution in a significant impact, so the umbrella of composite insulators to transform the state of glass insulators under icing along the surface electric field distribution can have a certain change; compare umbrella double umbrella and four electric field distribution in insulators visible four umbrella composite insulators has obvious advantages. Therefore, this article uses four umbrella of composite insulators.

    Umbrella umbrella umbrella umbrella diameter and spacing of composite insulators under icing equally obvious impact on the state of the electric field distribution, with the increase in the diameter of the umbrella, the same state icing composite insulation to the electric field distribution along the surface more uniform, along with the highest field strength increase umbrella diameter decreases. But after diameter composite insulators umbrella over 245mm, this trend is slowing down, in order to improve the electrical performance of insulators under icing state well and ensure self-cleaning insulators recommend Recovering Insulators large parachute diameter of not more than 245mmj with umbrella umbrella spacing increases, the strong decrease under the same state icing composite insulators exhibition large field, and there is no apparent saturation tendency, but in order not to increase the height of the insulator structure, while maintaining the umbrella spacing / 'umbrella extending in I above, Recommended umbrella spacing 140mm or less. Composite insulator umbrella and umbrella due to the large umbrella protected by its umbrella diameter of the entire composite insulators along the surface potential distribution was less affected.

    Composite insulators grading ring on the surface of the field strength to a certain extent Distribution icing conditions, in which O -5cm to raise from time to ensure maximum field near the high-pressure side and high pressure side gap icicles strong to achieve a better fit at the same time, in order to ensure raise insulator grading ring distance without diminishing its mainstay in arc distance thereby reducing the impact of flashover voltage, its vertical elevation from take Ocm.
