Abstract

The invention discloses a method for sampling and measuring filth degree of an insulator. The method provides a cleaning and sampling method for flushing by a pressure watering can, adds a project for measuring gray density in the measuring process, and solves the problem that the filth degree measuring project is not complete, so that the test result is more in accordant with the true situation. The invention also discloses a special set of sampling funnel equipment, and the equipment is portable to sample on site.

Description

technical field

[0001] The invention relates to a method and a device for measuring the degree of contamination of insulators in a power system. Background technique

[0002] Pollution flashover accidents of power transmission and transformation equipment seriously threaten the safety of power grid operation, and are one of the main accidents that power systems should focus on preventing. Scientifically determining the pollution level of the power grid and rationally selecting the level of external insulation configuration of equipment are effective measures to prevent grid pollution flashover accidents. The pollution degree of insulators is the only quantitative basis for dividing the pollution level of the grid, and it is of great significance for accurately determining the pollution level of the grid equipment.

[0003] For a long time, the pollution level of my country's power grid has been divided by using the annual maximum equivalent salt density with reference to GB...
