The present invention discloses an ion resistance reducing reagent that has the following ingredients in weight: conducting salt 50-95 percent, wet storage agent 0.5-10 percent, and buffer inhibitor 0.5-10 percent. The ion resistance reducing reagent does not easily bring dust in production, transportation and engineering; and can reduce pollution to the environment and physical injuries to operators. The present invention, which is used conveniently, can simplify engineering procedures, lower the cost and improve the engineering progression. With anti-freezing substances added, the present invention can be used in freezing cold regions and can still reduce resistance. The present invention has a wide range of applications.
Description
Technical field
The invention belongs to the electric conducting material technical field, particularly a kind of material that is used to reduce all kinds of grounding resistance of transmission.
Background technology
Resistance reducing agent is that a class is used for earthing device and is wrapped in around level and the vertical grounding electrode, and the composite material that reduces the earth resistance function is arranged.Because the resistivity of itself is very low, and the contact area increase, the contact resistance between electrode and soil can effectively be reduced.Be widely used on the earthing device of transformer and distribution station, power plant and industrial civilian installation, especially in high soil resistivity.
The tradition resistance reducing agent is being produced, is being had powder to add in the use, and since fineness requirement all more than 200 orders, so comparatively serious at the dust pollution of production scene, human body is also had harm; Need around level and vertical grounding electrode, excavate soil, great in constructing amount with the landfill resistance reducing agent, resistance is fallen slowly, and a couple of days or several months to fall resistance and just stablize; And remedial measure inconvenience, if earth resistance changes, excavation construction (wanting arrestment to turn round) once more impacts productive life etc.; The scope of application is wideless, and resistance reducing effect is not good yet in the frozen soil area.
Summary of the invention
The purpose of this invention is to provide a kind of new ion resistance reducing agent, applied widely, easy construction, to fall resistance quick, is difficult for polluting in production, transportation and the use.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of ion resistance reducing agent, mainly form by following components in weight portions:
Conducting salt 50-95 part NMF 0.5-10 part buffering corrosion inhibiter 0.5-10 part;
Above-mentioned ion resistance reducing agent can preferably be made up of following components in weight portions:
Conducting salt 70-90 part NMF 0.5-10 part buffering corrosion inhibiter 0.5-10 part.
Conducting salt in the said components can be selected from any one or a few in sodium salt, the sylvite etc.; Be preferably sodium salt; Sodium chloride more preferably.
NMF can be selected from any one or a few in xanthans, hydroxy ethyl fiber, the polyacrylamide etc., is preferably polyacrylamide.
The buffering corrosion inhibiter is any one or a few in borate, benzoate, molybdate, phosphate, Quadrafos etc., more preferably benzoate preferably.
When the environment for use temperature is lower than 0 ℃,, also can add cryoprotective substance 20-40 part in the above-mentioned ion resistance reducing agent as in-45 ℃-0 ℃ freezing area.This cryoprotective substance can be selected from any one or a few in the lower alcohols such as diethylene glycol (DEG), ethylene glycol, can be preferably from diethylene glycol (DEG), ethylene glycol.
In each component of ion resistance reducing agent of the present invention, except that the little xanthans of consumption (can be Powdered or graininess), other key component conducting salt, buffering corrosion inhibiter, and other NMF etc. be white granular; Cryoprotective substance is liquid.
The preparation method of resistance reducing agent of the present invention is very simple: only need each component with described proportioning mix and get final product, prepared ion resistance reducing agent is white granular (not containing cryoprotective substance) or paste (containing cryoprotective substance).
Ion resistance reducing agent of the present invention does not need to excavate in a large number soil in use, and direct cast or pressure injection get final product around earth electrode after only needing to be dissolved in it in suitable quantity of water.
Compared with prior art, the invention has the beneficial effects as follows:
(1) ion resistance reducing agent of the present invention adopts new prescription, its key component is the white granular material, the alternative lower alcohols cryoprotective substance that adds in freezing area is liquid, i.e. no powdered rubber or only contain the minute quantity powdered rubber in all raw materials, therefore in production, transportation and work progress, all be difficult for producing dust, can obviously reduce environmental pollution and operating personnel's physical impairment;
Do not need to excavate in a large number soil when (2) using, direct cast or pressure injection get final product around earth electrode after only needing to be dissolved in it in suitable quantity of water, can simplify construction procedure, and be easy to use, reduces cost, and improve construction schedule greatly;
(3) applied widely, can (45 ℃-0 ℃) use in freezing area behind the adding cryoprotective substance, resistance reducing agent is noncondensing, still prompt drop resistance soon.
