AI Technical Summary

Technical Problem

Existing technologies lack standards and schemes for selecting the amount of steel for DC deep well grounding electrode feed rods, resulting in a lack of effective basis for selecting the size of deep well grounding electrodes, which affects construction and corrosion prevention.

Method used

A method for selecting the amount of steel for feeder rods based on deep well grounding electrodes is provided. The amount of steel to be corroded is calculated by pre-set corrosion ampere-hours, and the required amount of steel for the feeder rod is determined by combining the pre-set annual corrosion percentage threshold and the wall size. The steel quantity is then judged to be qualified by calculating the percentage of corrosion.

Benefits of technology

It enables convenient and rapid determination of whether the steel quantity of the deep well grounding electrode feed rod is up to standard, avoiding blind selection, ensuring the mechanical strength and corrosion resistance of the deep well grounding electrode, and simplifying the design process.

Abstract

The application discloses a kind of based on deep well grounding electrode's feeding stick steel material selection method and related device, method includes: according to pre-set corrosion ampere-hour number calculation current deep well grounding electrode operation feeding stick's corrosion steel material quantity;Based on pre-set annual limit corrosion amount proportion threshold value calculation deep well grounding electrode's feeding stick required steel material quantity;According to the wall size of protective wall steel pipe, the length of current deep well grounding electrode's feeding stick, corrosion steel material quantity and feeding stick required steel material quantity calculate corrosion steel material quantity proportion;If corrosion steel material quantity proportion is greater than pre-set corrosion proportion threshold value, then the selection of current deep well grounding electrode's feeding stick steel material quantity is unqualified.The application can alleviate the technical problems that prior art lacks the selection standard and scheme of the steel material quantity of direct current deep well grounding electrode feeding stick.
