Problems solved by technology

The test results show that, on the one hand, after a period of operation, the chloride ions in the above-mentioned traditional drag reducer seriously corrode the steel grounding electrode, and are easy to be lost, and cannot maintain long-term performance; on the other hand, the organic components in it are relatively toxic, not only It pollutes the environment, and is also susceptible to aging due to underground biochemical effects, thereby denaturing and losing the effect of reducing resistance

Abstract

The invention relates to a long-acting antiseptic resistance-reducing agent for protecting a grounding device to normally run. The resistance-reducing agent is formed by mixing 35-70 percent by weight of bentonite and 30-65 percent by weight of petroleum coke. The resistance-reducing agent has the advantages of higher viscosity, compact structure, less influence by climatic factor due to difficult loss along with rain water on the basis of sufficient permeability, long-acting performance, obvious resistance-reducing effect, good antiseptic effect, no toxic element and no pollution to the environment.

Description

technical field [0001] The invention relates to an inorganic drag-reducing agent, in particular to a long-acting anti-corrosion drag-reducing agent for protecting the normal operation of a grounding device. Background technique [0002] At present, limited by objective conditions, such as high soil resistivity or other environmental and geographical conditions, the grounding device is susceptible to corrosion, or the system is poorly grounded due to high resistance, which will seriously endanger the power grid equipment. Safe operation, causing major economic losses and social impact. The resistance reducing agent can be used in substations, power transmission lines, chemical industry, communication, microelectronics and other grounding devices that are difficult to reduce resistance and the grounding body is easy to corrode in the soil environment. It can effectively improve the safe and reliable operation of electrical equipment and prevent poor grounding systems. happene...
