Problems solved by technology

[0011] Based on the objective problems of the existing drag-reducing products in the field, such as poor drag-reducing ability, unsustainable effect, and soil pollution, the present invention provides a drag-changing agent with a new formula, which is a water-compatible Conductive composite powder preparation, mixed with water and poured around the grounding body, can penetrate into the soil around the grounding body, and then naturally precipitate as the flow force weakens, forming a tree-root-like soil conductive path, making the electrical conductivity of the soil around the grounding network greater than that of the grounding network. Ten-fold enhancement, by filling the gaps with high soil resistivity around the grounding body, the conductivity of the soil in a certain local area is increased, thereby changing the soil resistivity

Abstract

The invention provides a resistance changing agent for changing soil resistance. The resistance changing agent is characterized by comprising a composite powder preparation for electric conduction. The composite powder preparation comprises the following raw materials by weight: 5-15 parts of graphite, 1-10 parts of mineral glue, 1-10 parts of resin, 1-10 parts of conductive cement, 1-10 parts of metal powder and 1-6 parts of industrial salt. In soil resistance changing, the resistance changing agent further comprises water. Furthermore the weight ratio between the water and the composite powder preparation is 33-100:16-48. The resistance changing agent can be well kept in the clearances among soil, gravels and rocks for effectively enlarging a conductive range next to a grounding member, thereby sufficiently discharging lightning current to ground when lightning occurs. Furthermore the resistance changing agent has relatively high solidifiability and is not easily washed away by rainwater. The resistance changing agent is totally composed of natural mineral materials and causes no pollution to soil, crops and plants.

Description

technical field [0001] The invention belongs to the technical field of resistance reduction, and in particular relates to a resistance modification agent for changing soil resistance. Background technique [0002] Grounding is an important means to ensure the safety of electrical, communication, microelectronics and other equipment, buildings and personal safety. In order to ensure the normal operation of the power system and the safety of people and equipment, the electrical equipment in power plants and substations must be reliably grounded and have a low grounding resistance value. It is usually very difficult to extend the ground body and expand the ground grid to meet such high requirements. Ground resistance reducing agent is a kind of auxiliary material, which has been widely used in grounding engineering. Its performance of resistance reduction and corrosion inhibition is stable and the effect is good. It has been written into national standards and related industry...
