The Calculation Method of Contamination Ratio Between Composite Insulator and Standard Disc Suspension Insulator

Abstract

The invention discloses a method for calculating the pollution ratio between a composite insulator and a standard disc-shaped suspension insulator. At present, the difference in pollution accumulation between composite insulators and standard disk-shaped suspension insulators needs to be obtained by conducting equivalent salt density and equivalent gray density tests on the pollution test strings suspended on site. It is relatively long, and hanging the pollution test string and carrying out the pollution test all rely on manual operation, and the work cost is high. At the same time, the test results obtained in a single area cannot be promoted and applied to other areas. The present invention obtains the atmospheric environment parameters and meteorological parameters of the target area, and directly obtains the pollution ratio of the composite insulator and the standard disc-shaped suspension insulator through calculation based on the above parameters. Regional meteorological parameters and atmospheric environment parameters can be applied to different regions, which can significantly improve work efficiency and reduce work costs.

Description

technical field [0001] The invention relates to the calculation of the pollution ratio of composite insulators and standard disc-shaped suspension insulators, in particular, it is an equivalent salt density sum of composite insulators and standard disc-shaped suspension insulators based on meteorological parameters and atmospheric environment parameters. The calculation method of gray density ratio. Background technique [0002] The determination of the pollution ratio of composite insulators and standard disc suspension insulators is of great significance to the insulation configuration of composite insulators in the design of transmission lines. Although the pollution flashover voltage of the composite insulator is relatively high, its surface pollution is far more than that of the standard disc suspension insulator in some environments. type disk-shaped suspension insulator, at this time its insulation configuration can be appropriately weakened. By determining the poll...

Problems solved by technology

[0003] At present, the determination of the pollution ratio of composite insulators and standard disc-shaped suspension insulators is mainly obtained by performing equivalent salt density and equivalent gray density tests on the pollution test strings suspended on site. The pollution accumulation time is as long as 2-3 years. It takes a long time. In addition, hanging the pollution test string and carrying out the pollution test rely on manual operation, and the work cost is high. Moreover, the manual test of the equivalent salt density and equivalent gray density brings test errors, which affects the determination of the pollution ratio.
