Abstract
The utility model provides nonmetal grounding modules, relating the improvement of grounding body in a lightning arrester. The utility model aims to provide nonmetal grounding modules mainly made of conductive non-metallic material, and used as a grounding body. According to the utility model, the outer ends of two modules are equipped with an electrode A and an electrode B, and electrodes at the inner ends of the two modules are connected by a connector. The nonmetal grounding module of the utility model little material used, low cost, greatly simplified construction, long service life and excellent stability, is especially suitable for being used in high resistivity soil area, such as a place where point of grounding has sandstone or rock strata around, and can be used for solving problems in grounding engineering. The product has no pollution, no toxicity, corrosion resistance, is convenient to us, and can be widely used in building grounding, lightning protection grounding, AC working ground, safety protection ground, and other grounding constructions.
Description
Technical field
The utility model relates to the improvement of earth electrode in the lightning arrester.
Background technology
Common earth mat construction is many with metallic conductor, is main as angle steel, round steel, steel pipe, copper rod, copper mesh, and its shortcoming is materials many, expensive big, construction complexity, life-span weak point, poor stabilities, use is difficult to get a desired effect in the high soil resistivity district.
Summary of the invention
The purpose of this utility model is to serve as main nonmetal earthing module as earth electrode with the conductive non-metals material.
Two module outer ends of the utility model are equipped with electrode A and electrode B, and the electrode of two module the inners connects by connector.
The utility model materials are few, expensive little, construction is simplified greatly, and the life-span is long, good stability, is particularly suitable for the high resistivity soil region and uses, as being sandstone or rock stratum around the earth point, available it solve a difficult problem in the earth work.This product is pollution-free, nonhazardous, anticorrosive, uses very convenient.Be widely used in the ground connection construction of " building ground connection, lightning protection, alternate current operation ground, safety protection earth " and other purpose.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Two module 2 outer ends of the present utility model are equipped with electrode A 1 and electrode B 4, and the electrode of two module 2 the inners connects by connector 3.
Be wrapped in nonmetal low resistance conductive material around the built-in non-corrosive metal (NCM) binding post of the utility model, binding post, and form firm contact.Nonmetal earthing module contacts good whole with one of the earth formation after imbedding the earth, since the utlity model has very strong preserve moisture, moisture absorption and stable conductivity, the metal earth electrode will significantly reduce by the module of the nonmetallic resistance of periphery and the contact resistance of the earth, reach the good resistance effect of falling.Because zero electromotive force of nonmetallic materials,,, can not produce that the oxygen type corrodes and Hydrogen corrodes more because itself be the electric conductor of nonmetallic materials so it can be to the corrosion that produces electrolysis of other metal yet.
The utility model adopts the conducting medium of chemically stable nonmetal conductor material as module, and its conductivity is not subjected to seasonal effect.Nonmetallic materials, electrolyte, hygroscopic agent and aseptic technic binding post by conductivity, good stability are formed.
Have moisture absorption, humectant properties, earth resistance is low and can maintain a long-term stability; In high soil resistivity, can effectively reduce earth resistance.
Behind heavy current impact repeatedly, resistance does not increase, and phenomenons such as no hardening, embrittlement, fracture take place.
Can stand-40 ℃ low temperature, northern extremely frigid zones is suitable equally.
Be burn into nonhazardous, environment friendly and pollution-free, long service life (greater than 30 years), simple installation.
Range of application
Working earthing, safety ground and lightning protections such as telecommunications building, mobile communication base station, microwave relay station, ground satellite receiving station, radar station, power station, transformer station, switchyard, ultra-high-tension power transmission line, electric railway, freeway toll station, oil depot, gas station, airport;
Working earthing and protective earthings such as computer room equipment, radio and television equipment, post and telecommunications program-controlled equipment, electromedical equipment;
Various skyscrapers and tall and big structures, showplace ancient building, tall and big memorial tower, flammable and explosive substance warehouse lightning protection or the like lightning protection.
