Problems solved by technology

However, if the soil resistivity is low, the soil medium will be more corrosive to metal, and the grounding resistance will gradually increase under the influence of corrosion factors after several years; if the soil resistivity is high, the corrosion is small, but the conductivity is poor

Abstract

The invention relates to a multi-path lighting protection bag and a pre-buried method of the lighting protection bag in soil, and the multi-path lighting protection bag is used for guiding thunder, short-circuit current and the like into the ground quickly under different geological conditions. Padding and multi-path extension agent are adopted in the multi-path lighting protection bag, wherein the padding is prepared by smelting and mixing of low-potential metal alloy, various raw mineral materials and chemical materials, and the multi-path lighting protection bag is arranged on grounding nets of industrial equipment, buried underground. Thus, a grounding device can be prevented from being corroded, quick electro exchange of light current on the grounding nets and surrounded soil can be guaranteed, ions can be generated continuously, electric conduction ways can be increased, continuous smoothness of the electric conduction ways can be guaranteed, counter electromotive force can not be generated, and therefore the pre-buried method of the lighting protection bag in the soil is a good lighting protection method. The multi-path lighting protection bag and the pre-buried method of the lighting protection bag in soil are suitable for lighting protection of underground grounding devices such as chemical industry facilities, electrical equipment, buildings and communication facilities.

Description

technical field [0001] The invention relates to the technical field of lightning protection and grounding, in particular to a multi-path lightning protection grounding package and its pre-embedding method in soil. Background technique [0002] As we all know, if some power equipment, buildings, chemical facilities, communication facilities, etc. are short-circuited to ground or encounter lightning strikes, if the huge instantaneous current cannot be introduced into the earth in time, the consequences will be disastrous. [0003] Electricity goes through three stages from the ground to the ground: [0004] Stage 1: The current is guided from the lightning rod of the equipment or building to the underground grounding system along the down conductor. In this stage, the free electrons of the metal conduct electricity, and its resistance depends on the metal itself. [0005] Phase 2: After the current is introduced into the underground grounding body, electrons exchange with the...
