Resistance reducing agent and preparation method and application thereof

Abstract

The invention provides a resistance reducing agent and a preparation method and application thereof, the resistance reducing agent comprises a combination of carbon, a sodium chloride source and ironpowder, and through the cooperation of the three, the resistance reducing agent has excellent resistance reducing effect, excellent corrosion resistance, long-term effect and stability; and when the resistance reducing agent is used for reducing the resistivity of the soil around the grounding body, the construction amount is small, the transportation cost is low, the economic benefit is remarkable, the resistance reducing agent has no influence on the environment such as the surrounding soil, the ecological environment cannot be damaged, and the resistance reducing agent has high applicationvalue.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering materials, and in particular relates to a resistance reducing agent and its preparation method and application. Background technique [0002] As an integral part of the power system, to control the voltage of the transformer within a safe range, it is necessary to effectively regulate the voltage through the transformer resistance grounding technology. The main evaluation index of the grounding device is its grounding resistance. According to the requirements of the national standard for the grounding resistance of electrical equipment, when the transformer capacity does not exceed 100 kVA, the grounding resistance should not be greater than 10 ohms. It should not be greater than 4 ohms; the grounding resistance of the grounding is proportional to the soil resistivity in the area, and inversely proportional to the square root of the total area of ​​the grounding grid. It is dif...

Problems solved by technology

This resistance reducing agent solves the defects of general resistance reducing agent packaging and difficult construction, and solves the problem that the grounding body cannot serve normally for a long time

However, it has been found through research that most of the drag reducing agents provided in the prior art use components such as graphene, resulting in a higher cost of the drag reducing agent; The resistance continuity is poor, and generally can only maintain the resistance reduction effect for 3 to 4 months, and needs to be replaced from time to time, otherwise it will endanger the safe and stable operation of the transformer and its line equipment
