Abstract
The invention discloses a corrosion-preventing and resistance-reducing grounding module. The straw pulp paper or the wood pulp paper is laid on the inner surface of a shell, the middle in the shell is provided with a sacrificial anode, and a sacrificial anode inner core is embedded into the sacrificial anode; and an inner cavity between the sacrificial anode and the shell is provided with a filling medium. The invention adopts the sacrificial anode using iron or copper as the inner core as a framework, adopts a high-water-retention material, a forming material, a metal corrosion inhibiting agent and a conducting electrolyte as the filling medium, adopts a porous plate made of a thin-wall sacrificial anode material as the shell and can prevent the corrosion of a grounding net and effectively reduce the resistance of the grounding net.
Description
Technical field
The present invention relates to lightning protection facility field, particularly a kind ofly be used for to prevent 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 objective of the invention is to overcome above-mentioned prior art deficiency, provide a kind of and can prevent ground net corrosion, can efficiently reduce the earthing module of grounded screen electric resistance again.
Technical scheme of the present invention 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.
It is that the sacrificial anode of inner core is a skeleton that the present invention adopts with iron or copper, adopts high water-keeping material, moulding material, metal inhibitor and conducting electrolyte as filled media, adopts porous plate that the thin-walled sacrificial anode material makes as shell.
The present invention 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.

Below in conjunction with accompanying drawing content of the present invention is described in further detail.
Embodiment
As shown in Figure 1 and Figure 2, the profile of corrosion-preventing and resistance-reducing module is a rectangle, inner frame is with the casting magnesium sacrificial anode of copper as inner core 1, and shell is that shell and inner frame adopt argon arc welding to be weldingly connected by the 1.6mm that adopts prior hole punch thick welding of magnesium plate or bonding forming.After the cavity inner wall that forms between inner frame and the shell is spread straw paper or wood pulp paper.The matching method of filled media is as follows: at first following prescription is formed proportioning and is pulverulent mixture:
Secondly, add the water of its gross mass 40-60% in mixture, mix is even, the filling compaction moulding.
| Form | Polyacrylic acid | Bentonite | Dead plaster | Imidazoline | Aluminium chloride | Potassium chloride |
| Percentage composition | ??1 | ??30 | ??40 | ??5 | ??12 | ??12 |
Its operation principle is: earthing module of the present invention and ground network are welded together the back landfill and water, penetration by water porous plate shell enters the filled media in the shell.Filled media and water are had an effect, on the one hand high water-keeping material absorbs moisture and keeps the moistening of integral module, moulding material curing molding under the effect of water on the other hand, guarantee with inner frame between close the contact, with the exception of this, corrosion inhibiter makes metallic framework and porous plate shell reduced by the corrosion rate of conductive ion as far as possible.Be weldingly connected between sacrificial anode skeleton and the porous plate shell, the mode protective earthing net with sacrificial anode slows down corrosion jointly.During work, the conductive ion in the filled media penetrates porous plate shell soil permeability towards periphery under the effect of moisture, forms root shape conductive path, enlarges the contact area with soil.
Sacrificial anode material described in the foregoing invention is magnesium alloy, kirsite or the composite material of the two; Skeleton is with copper, the iron casting sacrificial anode for its inner core; Housing is the sacrificial anode material thin plate of punching.
Described filled media is the mixture of water-keeping material, moulding material, metal inhibitor and conducting electrolyte; Water-keeping material wherein 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 or organic inhibitor or the compound of the two, and conducting medium can be inorganic salts such as aluminum sulfate, magnesium sulfate.
