Description

Earthing device of electrical equipment

Technical field

The utility model relates to a kind of earthing device of electrical equipment.

Background technique

China is at present in order to improve the corrosion resistance of steel material earthing or grounding means, the just hot dip on the outer surface of steel body Layers of copper in upper zinc layers, plating, wraps stainless steel layer, although these handicraft products can improve the corrosion resistance of steel body, Manufacture and use process in all different degrees of there are problems: such as, first steel body material is removed with industrial sulphuric acid Rust decontamination, then cleaned with sodium hydroxide solution, these techniques discharge toxic wastewater, waste residue, and exhaust gas pollutes environment, and anti- Corrosive effect is poor, and if zinc layers generate self-corrosion, layers of copper causes steel body to generate galvanic corrosion, and stainless steel easily produces in weight alkali environment Raw spot corrosion, pitting, the protection uncorroded ability of steel is poor, and internal steel body corrosion, ground resistance rises, and internal stainless steel Bulk resistor becomes larger, and generates security risk, burns out installations and facilities and threatens the life security of staff.Resistivity is big, thermostabilization Performance is poor, impacts intolerant to lightning current, and as blown, deforming when through-flow 16KA2/s, and production takes a lot of work, is time-consuming, wastes material energy Source, it is at high cost.The advantages of utility model device is that structurally reasonable, internal electrode core electric conductivity is excellent, and resistivity is small, heat Stability is excellent, resistance to heavy current impact, intact such as in the test of 20KA2/s, indeformable, and stainless steel protection shell Outside is equipped with anticorrosive, and conductive, drop resistance, the viscous glutinous agent of resin and graphite flat bar body do not discharge Toxic, environmental protection.

Summary of the invention

The utility model provides a kind of earthing device of electrical equipment, to overcome prior art construction unreasonable, hot galvanized layer There are self-corrosions, protect the uncorroded ability of steel body limited, and layers of copper easily makes copper and iron body generate galvanic corrosion, and stainless steel layer exists It is also easy to produce pitting, spot corrosion in caustic corrosion environment again, internal steel body corrosion is easily led to and generates security risk.And manufacturing process is multiple The problems such as miscellaneous, operating difficulties is time-consuming, waste material, the energy, at high cost.

Technical solutions of the utility model

The electrode core series winding structure that the earthing or grounding means fission shape structure of flat bar plate is combined by the individual aluminium sheet of 10 sections, copper sheet At.Aluminium sheet copper sheet compound electrode core is arranged in the inside of every economize on electricity pole piece, and stainless steel protection shell, electricity is arranged in external in electrode core Pole piece body both ends are arranged to slotting type connector；The electroconductive resin glue of anticorrosion bonding effect is brushed in the outer surface of stainless steel case Layer；The graphite flat bar body for letting out electric current and heat dissipation is dissipated on the outer surface of glue-line is pasted.In the outer surface of graphite flat bar body strength Electric conduction of carbon fiber felt body in glue.

The utility model remarkable advantage is: structurally reasonable, the electrode cores of device replace steel body electrode with flat aluminium sheet copper sheet Core, overcomes that steel bulk resistor is big, thermal stability is poor, intolerant to heavy current impact, carries out surface derusting with soda acid chemical mediator The technique of decontamination processing does not discharge noxious material, free from environmental pollution, and resistivity is small, thermostabilization, and resistance to heavy current impact such as exists It is indeformable in the heavy current impact of 18KA2/s, meet national Its Relevant Technology Standards, securely and reliably, installation connection is simple, Without galvanizing by dipping and electro-coppering Anticorrosion measure, environmental protection is free from environmental pollution, and anticorrosive, ground resistance is stablized, service life It is long, save material and the energy, saving of labor, time saving, at low cost, practical, generally applicable various electrical equipment grounding engineerings.Installation When can be according to the needs of earth work, also extensible, increases or decreases conductive section and drop resistance, decompression, equal pressure zone.
