Abstract
A method for preparing an earthing device made of steel material plated with anticorrosion layer includes welding steel material to be form of earthing electrode main component and welding seal on both ends of pipe, plating anticorrosion layer on external surface of said earthing electrode component by chemical means, inserting prepared steel earthing electrode main component into earthing hole and fixing said main component by parts.
Description
Technical field
The present invention relates to the manufacture method of earthing device.
Background technology
Traditional earthing device adopts ordinary metallic material and deep-well grounding, by metallic conductor electric current is imported the earth, its grounding resistance is subjected to factor affecting such as the humiture, density, contact pressure, electrolyte formula of extent of corrosion, the soil of conductor, and bigger unsteadiness is arranged.Earth electrode is for guaranteeing personal safety and the essential device that disposes of the normal operation of electric equipment.Existing earthing device is the plating anticorrosive coat earlier, welding then, and easy anticorrosive coat with weld damages in the process of welding, and this place is corroded earlier in the use, and then reduces the performance and the useful life of whole earthing device.
Summary of the invention
The present invention is in order to solve existing earthing device plating anticorrosive coat earlier, welding then, easy anticorrosive coat with weld damages in the process of welding, make the decreased performance of earthing device in the use, the problem that shorten useful life, proposed a kind of method of making steel grounding device coated with anti-corrosion layer, the step of the concrete technical scheme that addresses this problem is as follows:
Step 1, steel material is welded into the shape of earth electrode main part, the earth electrode main part includes cross and the turning shape structure of being made by tubing and sheet material, tubing two ends solder up;
Earthing device elder generation's welding earth electrode main part of the present invention and each accessory, and then plating anticorrosive coat have solved the easy problem that the anticorrosive coat of weld is damaged in the process of welding.This device not only has excellent corrosion resisting performance, and the stability of earthing device resistance value significantly improves, and has prolonged the useful life of earthing device, and has reduced cost, compares cost with copper earthing device and reduces by 4～5 times.Guaranteed the normal operation of personal safety and electric equipment simultaneously.
