The module adopts the sacrificial anode which takes iron or copper as the inner core as a framework, adopts high water-retentive material, molding material, metal corrosion inhibitor and conducting electrolyte as the packing medium, and adopts a perforated plate made of thin-wall sacrificial anode material as the shell, thus preventing a grounding screen from being corroded and efficiently reducing the resistance of the grounding screen.
Description
Technical field
The utility model relates to lightning protection facility field, particularly a kind ofly is used for preventing that ground net corrosion from can reduce the earthing module of grounded screen electric resistance again.
Background technology
Earthing module is one of a kind of effective way that reduces Resistance of Grounding Grids.The use of earthing module has avoided adopting resistance reducing agent to cause the side effect of ground net corrosion, but because its area is limited, therefore falls the resistance ability at regional its of some high resistant and be subjected to certain restriction.
The result of existing patent retrieval shows that disclosed patent earthing module reaches the purpose of falling resistance from two aspects: the one, and by increasing the surface area of module, number be content as described in 200820203333.4,200720128250.9 as application (patent); The 2nd, adopt conductive ion to increase the conduction function of electric current, number be content as described in 200920302263.2,200820141371.1,200820141372.6,200820128707.0,200720194591.6,200820065752.6 as application (patent); The 3rd, change the mode of electrolyte kind, number be content as described in 97107543.3,03232747.1 as application (patent).
Though above-mentioned patent is in most of the cases, solved the high problem of Resistance of Grounding Grids, have common shortcoming: (1) water holding capacity is low; (2) adopt the corrosivity conductive ion; (3) function singleness has only played certain resistance effect of falling.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned prior art deficiency, provides a kind of and can prevent ground net corrosion, can efficiently reduce the earthing module of grounded screen electric resistance again.
The technical solution of the utility model is to solve like this: spread straw paper or wood pulp paper at the inner surface of shell, middle in the shell is sacrificial anode, and the sacrificial anode inner core is embedded in sacrificial anode; Inner chamber between sacrificial anode and the shell has filled media.
Described filled media is the mixture of water-keeping material, moulding material, metal inhibitor and conducting electrolyte.
Water-keeping material can be cellulose family macromolecule, mineral-type or high-molecular organic material.
Moulding material is a dead plaster.
Metal inhibitor is made up of inorganic inhibitor, organic inhibitor or the compound of the two.
Conducting medium is aluminum sulfate or magnesium sulfate inorganic salts.
The technical solution of the utility model is that the employing of earthing module is that the sacrificial anode of inner core is a skeleton with iron or copper, adopt high water-keeping material, moulding material, metal inhibitor and conducting electrolyte as filled media, the porous plate that employing thin-walled sacrificial anode material is made is as shell.
The utlity model has following remarkable result: 1, possessed the effect that prevents ground net corrosion and reduce Resistance of Grounding Grids simultaneously; 2, the use of high water-keeping material make resistance reducing effect in the arid area or arid season still kept; 3, the use of moulding material has slowed down the invalid loss that the conducting electrolyte of inner filling causes with rainwater or groundwater level fluctuation; 4, the use of metal inhibitor makes conducting electrolyte fall resistance and corrosion of metal is alleviated as far as possible; 5, adopting with copper, iron is the sacrificial anode skeleton of inner core, and under the continuous consumption of sacrificial anode and form conductive path between the corrosion product, resistance reducing effect is not affected with the consumption of sacrificial anode; 6, modularized design is easy to storage, transportation and installation.
