Physical Resistance Reducing Agent
Principles and General Requirements of Long-lasting Physical Resistance Reducing Agent
This product adopts standardized production, with uniform material and simple construction requirements. It can be used in various types of It has good resistance reduction effect and anti-corrosion performance in soil and various climatic conditions, has a long service life and no environmental pollution.
Principle of resistance reduction
With the increasing development of power and electrical industries, higher standards for grounding resistance have been put forward. Due to limitations of objective conditions such as topography, geology, environment, and funds, it is difficult to meet higher grounding requirements using angle steel or angle iron grounding methods. Even if the requirements are temporarily met, ordinary grounding materials will corrode quickly due to the harsh environment, resulting in annual They all need to be rectified. The investment in capital and manpower is too large and the gain outweighs the loss. Practice has proved that the use of long-lasting anti-corrosion and resistance-reducing agents in grounding grids has obvious resistance-reducing effects, saves money, labor and is durable, and is well received by users.
The long-term anti-corrosion and resistance-reducing agent contains stable conductive ingredients, chemical electrolytes, metal passivation anti-corrosion agents, water-retaining agents and other ingredients. It is applied between the metal ground body and the soil. On the one hand, it can be in close contact with the metal ground body and the soil, expand the dispersion cross-sectional area, and reduce the contact resistance between the metal ground body and the soil. On the other hand, it can spread to the surrounding soil during construction. The flow and penetration in the pores reduces the resistivity of the surrounding soil, forming a low-resistance area with gentle resistivity change around the grounding body, significantly reducing the grounding resistance of the entire ground network
One product use
Reduce working grounding and protective grounding Lightning protection grounding, anti-static grounding and anti-interference grounding grounding device grounding resistance improve the quality of the device and extend its service life. It is suitable for grounding poles and towers of power plant substation grounding grids, power and communication lines, lightning protection and anti-interference grounding of various weak current equipment, oil depots, explosive depots and other flammable and explosive storage and production sites. Various types of soil and various climates will not affect the performance of this product.
Second resistance reducing agent
Main technical parameters and performance indicators
Reducing resistivity The higher the resistivity of the soil, the more significant the resistance reduction will be.
Stability and long-term effectiveness, the theoretical validity period of the resistance reducing agent is more than one year.
Its water retention and water absorption are significantly improved compared to previous products.
Four resistance reducing agents
Construction and general requirements
Pre-construction inspection items and requirements
①The resistance reducing agent should be of the same brand and model.
②The water is clear and pollution-free. There is no sediment or other debris in the water.
③The size and shape of the trench holes meet the design requirements, the four walls are relatively flat, and there are no debris in the trench.
④ The vertical ground pole is placed in the center of the hole, and the horizontal ground pole is centered horizontally. The distance from the bottom of the trench is not less than and is relatively uniform. If necessary, it can be fixed with a thin wire.
⑤The grounding down conductor has been painted with anti-rust paint according to the design requirements and has initially set.
Preparation of resistance reducing agent
Add water according to the weight ratio of water resistance reducing agent ~ and stir thoroughly until it becomes a sticky paste. The amount of water used for horizontal grounding is just enough to moisten all the dry powder and stir it into a paste. The amount of water added with resistance reducing agent for vertical ground holes can be higher depending on the situation. Excessive water addition will extend the construction time.
Initial inspection of pouring and coating
Gently pour the prepared paste resistance reducing agent to prevent mud and debris from mixing into the resistance reducing agent into the ground trench hole until the grounding is completely covered. Extremely, and the coating thickness shall not be less than the initial measurement, and the four walls of the drilled hole shall be sufficient, and supplement shall be made if insufficient.
Re-inspection and backfilling
After the resistance-reducing agent has initially set, check in detail that the coating of the resistance-reducing agent should be even and full, with no omissions or debris mixed in, and the thickness of the coating should be the thinnest. No less than, if insufficient, add resistance reducing agent. After the inspection is correct, remove the fixed thin wire and lightly backfill with fine soil without hard objects and branches to a thickness of above, then add other soil and tamp it down. The compacted backfill surface should be slightly above the surrounding ground level.
Requirements for grounding down conductors
The entire section of the grounding down conductor at the surface junction needs to be painted with epoxy bitumen paint or other durable paint. The length of the underground section should be such that the resistance reducing agent is buried. The length of the upper part of the ground shall not be shorter than .
Deep well grounding
Deep well grounding is sometimes necessary. Usually the well depth is determined by finding a formation or groundwater with low resistivity, which is usually tens of meters. Special machinery is used to drill holes during construction, and the hole diameter is ~. Sometimes it is necessary to use local blasting to loosen the surrounding soil to fill it with drag-reducing agent
to expand the drag-reducing effect. The ground electrode is a steel pipe with through holes drilled into the four walls. Use pressure to inject the prepared resistance-reducing agent into the pipe. Through the wall hole, the resistance-reducing agent surrounds the steel pipe from both inside and outside and enriches the entire borehole. Resistance reducing agent_Copy/>
Product Features
b Increases the equivalent cross-sectional area of the grounding body and the contact area with the soil.
bGood adsorption performance makes the grounding body and soil more closely combined, eliminates the contact resistance between the grounding body and soil, and improves the electric field distribution in the soil.
b Good permeability, penetrates deep into the soil and rock crevices, forming a network of tree roots, increasing the drainage area in the ground and reducing the dissipation resistance in the ground.
bProtect the grounding body from various corrosion and infringements in the soil.
bThe unique negative resistance characteristic reduces the potential distribution gradient between the ground surface and the device when the ground body leaks instantaneously, improving the safety protection and reliability of personal equipment and facilities.
