Problems solved by technology

For a long time, the wire structure has been fixed on the pole tower with iron hoops. However, the harsh weather environment and rainwater erosion lead to rust and corrosion of the iron hoops of the pole tower. In our streets and alleys, we can see the rust of utility poles everywhere. Overgrown
This will not only affect the environment and image of the city, but at the same time, the corrosion damage will also lead to the loosening and falling off of the fasteners, affecting the safe power supply and causing power accidents

Embodiment Construction

[0016] The method of the present invention will be described in detail below with specific examples.

[0017] A 380V electric pole tower iron ferrule rust treatment method, the steps are as follows:

[0018] (1) Conduct a semi-quantitative analysis of the rust on the surface of the iron hoop of the pole tower to determine the quality of the rust;

[0019] Using a corrosion thickness gauge to measure the rust thickness of the iron hoop of the tower, the maximum corrosion depth is 0.001cm, and the degree of corrosion of the iron hoop is judged to be mild corrosion. At the same time, the diameter of the measuring pole is 21cm, the width of the iron hoop is 5 cm, and the length of the ear of the iron hoop is 4 cm; the estimated area of ​​the rusted part is: (3.14×21+2×4)×5=369.7cm 3 : Estimate the amount of rust products based on rust thickness and area: 5.24g / cm 3 × 0.001 × 369.7 = 1.94 (g)

[0020] (Note: The rust density is about 5.24g / cm 3 ).

[0021] (2) Determine the ac...

Abstract

The present invention proposes a method for treating iron ferrules of low-voltage power transmission and transformation lines, which includes: semi-quantitatively analyzing the rust on the surface of iron hoops, determining the amount of cleaning agent required, spraying the cleaning agent, washing with pure water, Drying, spraying paint, etc. The process is simple and practical, and it is convenient for on-site implementation. It does not affect the power supply and can ensure safety and reliability. It is convenient for construction at high places and has a good anti-corrosion effect. It can be extended to the protection of infrastructure towers such as telecommunications and networks.

Description

technical field [0001] The invention relates to a method for treating rust stains of iron hoops of poles and towers of low-voltage power transmission and transformation lines. Background technique [0002] Electricity is the lifeblood of the national economy and the blood of industry. At present, most of the power transmission is carried out by means of poles and towers. For a long time, the wire structure has been fixed on the pole tower with iron hoops. However, the harsh weather environment and rainwater erosion lead to rust and corrosion of the iron hoops of the pole tower. In our streets and alleys, we can see the rust of utility poles everywhere. rampant. This will not only affect the environment and image of the city, but at the same time, the corrosion damage will also lead to the loosening and falling off of the fasteners, which will affect the safe power supply and cause electric accidents. Therefore, it is extremely important to clean up the corrosion of iron h...
