Description
Technical field
The present invention relates to the grounding device technology for conduction, a kind of earthing module being connected with wire.
Background technology
The Chinese utility model patent of existing a kind of Patent No. CN94230002.5 entitled " low resistance earthing module "
Disclosing a kind of low resistance earthing module, the cast of nonmetal electrolytic gel thing form, heart is enclosed with pole piece, this pole piece
Module body is stretched out in one or both ends, securing member it be connected with lightning protection, lightning protection.When earthing module is longer or heavier
Time, netted or bar-shaped skeleton can be set in module body, in case fractureing.It is low that this earth resistance has resistance, etch-proof
Feature, after standing heavy current impact, its resistance change rate≤20%.The fall overcoming conventional art is hindered by this patented technology
Agent inconvenience in use serves positive role, but, low resistance earthing module disclosed in this patent, by pole piece and non-
Electrolytic etching of metal gelling thing cast forms, owing to it is integrally located in fall resistance layer as the metal pole piece of electrode, and as conduction
The electrolyte ion entirety contact of material, not only seriously corroded, service life is short, it is often more important that the making of earthing module
Raw material and structure design are unreasonable, cause conduction instability, conduct electricity uneven；And this module is by by pole piece and non-
Electrolytic etching of metal gelling thing cast forms, therefore the highest with intensity, accordingly, it would be desirable to this low resistance earthing module
Make raw material and structure is improved further.
Summary of the invention
The technical problem to be solved be provide for above-mentioned prior art present situation a kind of lightweight, intensity is high,
Conduct electricity very well and a kind of earthing module of length in service life.
The present invention solves the technical scheme that above-mentioned technical problem used: this earthing module, includes module body, and it is special
Levy and be: the basic composition of the formula of described module body is as follows: coke powder 13～17 parts, cement 1.5～8 parts, graphite
Powder 0.3～5 parts, described part is weight portion.
As improvement, also including ion releasing agent 0.3～5 parts in described formula, described part is attached most importance to part, maximizes
The ionization soil conductivity effect realizing electrolyte.
Improving, described ion releasing agent is one or more mixture of calcium chloride, sodium chloride, magnesium chloride again, by dividing
Solve, penetrate into surrounding soil to improve edaphic condition and to increase electric conductivity.
Improving, described module body is embedded with the conductive earthing body that can convenient be connected with wire again.
Improving, described conductive earthing body is grounded metal rod or grounded metal block or for have excellent conductive performance again
Nonmetal block, with the earth soil close contact, the energy of safe diffusing thunder and lightning makes it leak into the earth.
Improve again, described module body is provided with the preformed hole that can place conductive earthing body.
Improving, the manufacture method of described earthing module comprises the following steps again, according to above-mentioned formula proportion, by coke powder,
Cement, graphite powder mix, and stir, and add water to mixture thick, then by thick mixing
Thing is positioned over molding in die body, places and sloughs die body in 1～7 day, is finished product；If also including ion at formula to release
If putting agent, ion releasing agent and coke powder, cement, graphite powder are mixed together, remaining step and above-mentioned phase
With.
Compared with prior art, the present invention because of the basic composition of the formula of module body as follows: coke powder 13～17 parts, water
Mud 1.5～8 parts, graphite powder 0.3～5 parts, described part is weight portion.The advantage of this formula is: first, institute
State earthing module to exist due to coke powder, therefore himself have the strongest moisture-absorbing moisture-keeping ability, make earthing module itself protect
Hold moisture state, and the Soil conservation of surrounding can be made to moisten, thus ensure that earthing module possesses good electric action；
Second, make the raw material of earthing module, coke powder, cement and graphite powder are respectively provided with good electric conductivity, particularly stone
Powdered ink and coke powder have more the electric conductivity of extra-heavy, and the earthing module therefore having three kinds of raw materials to make inherently has excellent
Electric conductivity, i.e. uses above-mentioned raw material to have excellent soil affinity and conducting medium, its electric conductivity not by seasonal effect,
Thus provide stable earth resistance, and nonmetallic materials make to form one between metal and the soil that resisitivity is huge
The change shallower low resistance region of ratio, when heavy current impact, it is possible to decrease grounding body, earth lead transient state electric potential gradient,
Reduce step voltage and contact voltage, reduce the probability of spot potential counterattack；4th, this earthing module use cement with
Coke powder and graphite powder are made, thus have that density is high, corrosion resistance is strong, electric conductivity is high, comprcssive strength is big
Feature；5th, the present invention also includes ion releasing agent in formula, described releasing agent such as: calcium chloride, sodium chloride,
The electrolytes such as one or more mixture of magnesium chloride, make electrolysis mass-energy high concentration penetrate into enduringly in soil, reach
Quickly reduce earth resistance purpose, then further increase earthing module electric conductivity.
