Embodiment 1

[0024] An environment-friendly water-soluble grounding resistance reducing agent of the invention is divided into two components, A and B.

[0025] Among them, component A is solid water-soluble silicate, such as sodium silicate and potassium silicate; component B is liquid inorganic acid, such as sulfuric acid and hydrochloric acid.

Embodiment 2

[0027] A method of using the water-soluble grounding resistance reducing agent based on the first embodiment of the present invention comprises the following steps:

[0028] S1. Mix components A and B to make a slightly alkaline mixed solution;

[0029] S2. Test the grounding resistance within the grounding range, and pour the mixed solution in S1 into the soil until the grounding resistance meets the standard requirements;

[0030] S3. Re-pour component B in the grounding range until the soil is close to neutral, so that the mixed solution will form a gel and form a node resistor in the soil.

Embodiment 3

[0032] On the basis of Embodiment 2, the usage method is more specifically:

[0033] S11. Dissolve component A in water at a weight ratio of 30%, then slowly add component B while stirring to make a mixed solution with a pH value of 8-9;

[0034] S21. In the grounding range, according to the grounding resistance test standard, set up a grounding resistance testing instrument to test the grounding resistance, pour a mixed solution with a pH value of 8-9 in the grounding range, the solution will naturally penetrate into the soil, and observe the grounding resistance Test the test value of the instrument until the test resistance value fully meets the requirements of the grounding resistance standard;

[0035] S31. Pour 10% component B liquid in the grounding area again until the soil pH value of multi-point sampling is 6.8 close to neutral, so that the silicic acid generated in the mixed solution infiltrated into the soil will produce gel and the soil and soil The moisture form...

Abstract

The invention relates to the field of a connecting electric conductor, particularly to an environment-protection water-soluble grounding resistance reducing agent and a use method thereof. The environment-protection water-soluble grounding resistance reducing agent comprises an A component and a B component, wherein the A component is solid-state water-soluble silicate; the B component is liquid state inorganic acid; the use method comprises the following steps of S1, performing mixed reaction on the A component and the B component to generate a slightly alkali mixed solution; S2, testing grounding resistance within a grounding range, and pouring the mixed solution obtained in the step S1 into soil until the grounding resistance satisfies standard requirement; and S3, pouring the B component into the soil within the grounding range until the soil is close to be neutral, and enabling the mixed solution to generate into gel and forming a node resistor in the soil. By adoption of the environment-protection water-soluble grounding resistance reducing agent, digging of the soil within the grounding range is not needed; instead, the grounding resistance reducing agent is directly poured to the surface of the soil within the grounding range to be naturally permeated into the soil; and the produced silica gel body is combined with the soil and then is not subjected to rain wash and run off, so that the grounding resistance reducing effect is long-term and effective in a condition of not removing the soil within the grounding range.

Description

technical field [0001] The invention relates to the field of connecting electrical conductors, in particular to a method for using an environment-friendly water-soluble grounding resistance reducing agent. Background technique [0002] With the increasingly stringent requirements for lightning protection grounding of buildings, grounding of electronic equipment signal power systems, and grounding of power systems, the grounding resistance of all grounding projects has become an indicator that must be monitored. Due to the differences in the environment and geological soil of the grounding project, In the absence of human intervention, the grounding resistance is difficult to meet the requirements of the grounding resistance standard of the grounding project. The grounding resistance reduction has become a necessary measure. The environmentally friendly grounding resistance reducing agent has become a necessary means to solve the grounding resistance reduction project to reduc...
