Problems solved by technology

However, in order to test the atmospheric corrosion resistance of metal materials of power grid transmission line poles and towers, it is necessary to carry out long-term (generally more than 1 year) on-site metal sample hanging test on transmission line poles and towers in a harsher environment. Due to the influence of bad weather, the metal sample has the risk of falling off and being lost, while the traditional exposure test rack needs to use sample clamps to fix the sample, the structure is complex and the sample is prone to fall off, which affects the success rate of the test, and is not suitable for harsh On-site metal sample hanging test of power grid transmission line poles and towers under environmental conditions

Abstract

The invention discloses a fixing frame for a metal sample sheet atmospheric corrosion exposure test, relates to the technical field of power grid safety performance testing, and is used for solving the problems that a traditional exposure test frame cannot meet atmospheric corrosion resistance detection of a power grid electric transmission line tower metal material. The fixing frame for the metal sample sheet atmospheric corrosion exposure test comprises two vertical beams arranged in parallel and a plurality of cross beams vertically arranged between the two vertical beams and connected with the two vertical beams; a metal sample sheet is fixed between each two adjacent cross beams. The fixing frame for the metal sample sheet atmospheric corrosion exposure test is used for fixing the metal sample sheets, to improve the success rate of the atmospheric corrosion resistance detection test of the power grid electric transmission line tower metal material.

Description

technical field [0001] The invention relates to the technical field of power grid safety performance detection, in particular to a fixing frame for atmospheric corrosion exposure tests of metal samples. Background technique [0002] Atmospheric corrosion resistance is an important environmental adaptability of metal materials. Not only the users pay great attention to this performance index, but also the engineering design department must focus on this performance index. Power grid transmission line towers are distributed in different areas and are subjected to atmospheric corrosion in different environments. It is particularly important for the safe operation of the power grid to study the characteristics of atmospheric corrosion in different areas and the atmospheric corrosion resistance of metal materials for power grid transmission line towers in each area. In order to obtain the atmospheric corrosion resistance of the metal materials of power grid transmission line pole...
