Abstract
The utility model relates to a device for replacing an aluminum power transmission bar of an electrolytic cell for an aluminum factory with a copper power transmission bar. In an aluminum factory electrolytic cell workshop, power transmission lines and wires of the electrolytic cell use copper bars to transmit electric energy, the copper power transmission bar is easy to cool, and easily realizes constant temperature, and has higher mechanical strength, no low-temperature brittleness and easiness in compression processing and installation; moreover, the cost is reduced, and the working efficiency is improved.
Description
Affiliated technical field
The utility model relates to the device of an electrolyzer aluminium transmission of electricity row of aluminium manufacturer with copper transmission of electricity row replacement, has not only reduced cost, and has improved working efficiency.
Technical background
At present, the transmission line of the electrolyzer in most domestic aluminium manufacturer electrolyzer workshop, lead all adopt aluminium transmission of electricity row A transmission of electric energy.Though cheap, because the original natural defective of aluminum attribute, the line loss that causes is big, be prone to oxidation, maintenance is big, and cost is raise, production efficiency reduces.
Summary of the invention
In order to solve the original natural defective of aluminum attribute, the line loss that causes is big, be prone to oxidation, maintenance is big, and cost is raise, and production efficiency reduces.The utility model provides the electrolyzer aluminium transmission of electricity row of a kind of aluminium manufacturer device with copper transmission of electricity row replacement.Copper transmission of electricity row not only is easy to dispel the heat, is easy to realize the constant of temperature, and have higher physical strength, no low temperature brittleness is easy to compression process and installation.
The technical scheme that its technical problem of the utility model solution is taked is:
The conductivity contrast of aluminium transmission of electricity row A and copper transmission of electricity row B; Aluminium transmission of electricity row A and the contrast of copper transmission of electricity row B heat conductivility: the safe current carrying capacity of copper is bigger than aluminium, and copper transmission of electricity row B is more conducive to dispel the heat, is easy to realize the constant of temperature more to save the space; Aluminium transmission of electricity row A contrasts with copper transmission of electricity row B chemical property: fine copper has fabulous heat conduction, electroconductibility, and its electroconductibility is only second to silver and occupies second of metal.Copper has excellent chemical stability and corrosion resistance nature, is good electrician's metallic substance; The installability of aluminium transmission of electricity row A and copper transmission of electricity row B: copper transmission of electricity row B has higher physical strength, no low temperature brittleness is easy to compression process and installation; The maintainability of copper transmission of electricity row B and aluminium transmission of electricity row A: copper transmission of electricity row B is easy to welding.
The beneficial effect of the utility model is: copper transmission of electricity row not only is easy to dispel the heat in realizing the constant of temperature, and have higher physical strength, no low temperature brittleness is easy to compression process and installation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is that the schematic diagram of aluminium manufacturer's electrolyzer wherein 1 is winding displacement for lead row 2
A is that aluminium transmission of electricity row, B are copper transmission of electricity rows among Fig. 2
Embodiment
1. the conductivity contrast of aluminium transmission of electricity row A and copper transmission of electricity row B
Arrange the cross-sectional area of A, every meter volume, every meter quality, every meter price, line loss hourly through Theoretical Calculation copper transmission of electricity row B and aluminium transmission of electricity, consider that it is feasible that copper transmission of electricity row B replaces the aluminium transmission of electricity to arrange A.
2. the heat conductivility contrast of aluminium transmission of electricity row A and copper transmission of electricity row B
The fine copper thermal conductivity is 401w/ (m.k), and the thermal conductivity of fine aluminium is 237w/ (m.k): the heat conductivility of hence one can see that copper is better than aluminium, and promptly copper is easier to heat radiation than aluminium, from the reaction aspect, and under the situation of identical line loss, the temperature rise ratio aluminium of copper low.Physical properties by metal can know, year the rising of temperature, its conductivity descends: the while, its resistance value increased, and promptly line loss also increases.Moreover because big than aluminium of the safe current carrying capacity of copper, copper transmission of electricity row B is more conducive to dispel the heat, is easy to realize the constant of temperature more to save the space.
3. aluminium transmission of electricity row A and the contrast of copper transmission of electricity row B chemical property
Aluminium is active metal, and the surface of aluminium forms the dense oxidation film of shouting about 50 dusts immediately in dry air, makes not further oxidation and water-soluble of aluminium; But increased contact resistance at this point, line loss is greatly increased.Then very easily burning of the powder of aluminium and air mixed in addition; Fused aluminium can fiercely react with water; Can many MOXs be reduced to corresponding metal under the high temperature; Aluminium is amphoteric, promptly is soluble in highly basic, also can be dissolved in strong acid.Fine copper has fabulous heat conduction, electroconductibility, and its electroconductibility is only second to silver and occupies second of metal.Copper has excellent chemical stability and corrosion resistance nature, is good electrician's metallic substance
4. the installability of B is arranged in aluminium transmission of electricity row A and copper transmission of electricity
The ultimate compression strength of aluminium transmission of electricity row A is more than or equal to 68.6N/mm
2, the ultimate compression strength of copper transmission of electricity row B is more than or equal to 206N/mm
2, copper transmission of electricity row B has higher physical strength, no low temperature brittleness is easy to compression process and installation.
5. copper transmission of electricity row B and aluminium are transmitted electricity and arranged the maintainability of A: copper transmission of electricity row B is easy to welding.
