Fixing device for corrosion coupon of transmission tower

Abstract

The invention relates to a fixing device for a corrosion coupon of a power transmission tower. The fixing device comprises a square main body frame made from poly-tetra-fluoro-ethylene material, a meshed partition plate made from poly-tetra-fluoro-ethylene material and arranged in the lower part of the square main body frame and a bottom water tank formed by sealed bonding plates and arranged on the outer side of the main body frame of the lower part of the meshed partition plate; in addition, a plurality of diagonal tensile strengthening beams are arranged on five square surfaces, excepting the top surface, formed by the main body frame. The device provided by the invention is used for performing a field exposure test on the corrosion coupon of the power transmission tower; as the meshed structure is arranged at the lower part of the device, the corrosion coupon is prevented from falling and losing; since only the diagonal tensile strengthening beams are arranged at four sides of the device, the field corrosion test is complete; the device can be used for researching the corrosion situation and corrosion resisting measures of the power transmission iron for a long time, so as to provide full supplement and correction for accelerated corrosion test data of an indoor lab, therefore the device is of great significance for corrosion and protection works of the tower.

Description

technical field [0001] The invention belongs to the technical field of material corrosion, in particular to a fixing device for a corrosion coupon of an electric transmission tower. Background technique [0002] The reliability of the anti-corrosion protection performance of transmission tower structural parts is one of the important factors affecting the long-term safe operation of the line. Most of the high-voltage transmission lines are various forms of iron towers and cross-arm components with carbon steel structure as the main structure. For the carbon steel components in the outdoor atmospheric environment all the year round, they will be subject to chemical corrosion and electrochemical corrosion, thereby shortening the service life of the iron tower and causing Security risks. [0003] At present, the research on atmospheric corrosion generally adopts the indoor accelerated corrosion test method, which has the characteristics of short period and controllability, but...

Problems solved by technology

Most of the high-voltage transmission lines are various forms of iron towers and cross-arm components with carbon steel structure as the main structure. For the carbon steel components in the outdoor atmospheric environment all the year round, they will be subject to chemical corrosion and electrochemical corrosion, thereby shortening the service life of the iron tower and causing Security risks

[0003] At present, the research on atmospheric corrosion generally adopts the indoor accelerated corrosion test method, which has the characteristics of short period and controllability, but compared with the field exposure test, this method is not reliable and authentic, and it is difficult to reflect The real situation of atmospheric corrosion in a certain area

Moreover, the corrosion test pieces of the iron tower field exposure test carried out especially for the power system are easy to be lost, resulting in the ineffectiveness of the iron tower field exposure test
