Problems solved by technology

[0004] However, since the power grid transmission lines pass through many areas, if the transmission line towers are subjected to atmospheric exposure tests in each area, this will not only increase the investment in manpower and material resources, but also prolong the acquisition of atmospheric exposure tests for transmission line towers in different environments. During the exposure test, the atmospheric corrosion rate time of the atmospheric corrosion coupon set on the transmission line tower

Abstract

The invention discloses a method for measuring the corrosion resistance rate of atmospheric corrosion coupons, relates to the technical field of corrosion resistance, and aims to reduce the number of test stations for conducting atmospheric exposure tests on power transmission line poles. The measurement method includes obtaining the air pollutant information of each grid transmission area that the grid transmission line passes through; classifying each grid transmission area according to the main pollutant types in the air pollutant information, and obtaining N types of grid transmission areas, from each type Select any transmission area of ​​the grid in the transmission area of ​​the grid as the test site, and conduct the atmospheric exposure test of the transmission line tower in the transmission area of ​​the grid, and obtain the corrosion resistance rate of the atmospheric corrosion coupon. The method for measuring the corrosion resistance rate of the atmospheric corrosion coupons provided by the invention is used in the atmospheric exposure test of transmission line towers.

Description

technical field [0001] The invention relates to the technical field of corrosion resistance, in particular to a method for measuring the corrosion resistance rate of atmospheric corrosion coupons. Background technique [0002] At present, grid transmission generally uses transmission line tower support and overhead grid transmission lines, and considering that in the process of grid power transmission, grid transmission lines pass through many areas and the environment is complex, therefore, transmission line towers need to have good environmental adaptability, To ensure the normal operation of power grid transmission. [0003] In order to ensure the normal operation of power grid transmission, it is generally necessary to monitor the atmospheric corrosion of transmission line poles and towers in different environments to obtain the atmospheric corrosion rate of transmission line poles and towers in different environments, so as to determine the resistance of transmission li...
