Problems solved by technology

The service transmission tower and the lightning protection tower are all in the wilderness, and cannot be connected to the power supply, which brings difficulties to the high-speed inspection work on site. Therefore, it is very important to develop a method for on-site high-speed inspection of the service transmission tower and the lightning protection tower without an external power supply. necessary

Embodiment Construction

[0017] The following examples of the present invention will be further described in detail. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0018] An on-site high-power inspection method suitable for tower material structures, the steps of the method are as follows:

[0019] ⑴ Grinding, in the grinding process, it is specifically divided into:

[0020] ① Coarse grinding: Use a rechargeable electric grinder to remove the galvanized layer on the tower materials of the power transmission tower and lightning rod tower in service to reveal the metallic luster;

[0021] ②Fine Grinding: Use a rechargeable electric grinder to grind with No. 400 and No. 600 metallographic sandpaper. The force should be uniform when grinding. The grinding time of each sandpaper should not be too long. When the old scratches completely disappear, the new ones The sandpaper can be replaced when the marks are even and consiste...

Abstract

The invention relates to an on-site high-power examination method suitable for a tower material texture. The method comprises the following steps: (1) grinding a to-be-examined surface; (2) performing polishing in a chemical polishing method; (3) performing nitric acid and alcohol erosion; (4) performing high-power examination including observing the to-be-examined surface, or laminating the surface and taking the laminated surface back to a laboratory for careful analysis. The method can analyze the material of an in-service power transmission iron tower and a lightning rod iron tower and evaluate the life of the towers.

Description

technical field [0001] The invention belongs to the technical field of power equipment maintenance, in particular to an on-site high-magnification inspection method suitable for tower material structures. Background technique [0002] The power transmission tower and lightning rod tower in service in the power system cannot be cut off for metallographic analysis. To conduct on-site high-magnification inspection of tower material organization, grinding, polishing, erosion, on-site high-magnification observation and photography must be carried out on the tower material. Metallographic lamination. The service transmission tower and the lightning protection tower are all in the wilderness, and cannot be connected to the power supply, which brings difficulties to the high-speed inspection work on site. Therefore, it is very important to develop a method for on-site high-speed inspection of the service transmission tower and the lightning protection tower without an external power...
