Description
Technical field
The utility model is related to bus duct technical field, specially a kind of vertically arranged heat sinking chip bus duct.
Background technology
With the development of society, modern high-rise building and large-scale workshop need huge electric energy, hundreds and thousands of peaces can be transmitted
The bus duct for training powerful electric current is widely applied.Latest model bus duct is the conductor outer wrapping using high-purity copper bar as conductor
Insulating materials, then the high strength sectional material drawn with almag make shell, and three phase lines in electrical voltage system are arranged into (ABC phases
Row), zero-emission (N rows), a ground protection row (PE rows) combine the power distribution equipment of the efficient conveying electric current being assembled into.
Due to the presence of resistance and impedance in conductor, bus duct, which is powered in operation, can produce heat, each position temperature of bus duct
Degree can gradually rise, to enable bus duct safe operation, it is ensured that its each spot temperature meets the requirement of national standard, it is necessary to by it
The heat of generation is distributed.
It is known that the influence in order to eliminate conductor kelvin effect, conductor copper bar must make flat thin rectangle shape as far as possible
Shape, but due to busway inserting case tapping unit, jointing and assembly technology the need for, it is necessary to wider front and rear covers are set
Plate, such bus duct cross section has just been designed to dies.Copper bar is produced during vertically arranged bus duct energization operation
Heat be transmitted to the side plate of bus duct shell from copper bar side, then distributed to conduct, in the way of convection current.Because air is
Thermal conductivity very low heat-insulating material, heat loss through conduction does not have effect substantially.Because bus duct is right angle setting, connect with side plate lateral surface
Tactile air heats rise, and air is formed effective convection current, so the main heat sink mode of vertically arranged bus duct is convection current
Radiating.But because five conducting coppers are arranged superposeds, and radiating surface is only two lateral surfaces of left and right side plate, radiating effect
It is unsatisfactory.In order to improve radiating effect, traditional approach is to add radiating along longitudinal direction on the outside of side plate when drawing busbar side board
Muscle, but due to the restriction of assembly production technique, radiating ribs can only very little, highly no more than 3 millimeters, the shadow to improving radiating effect
Sound is limited.Due to the thermal Finite distributed in the bus duct unit interval to external environment, to make each spot temperature of bus duct not surpass
The requirement of national standard is crossed, the heat produced in the bus duct unit interval is only reduced, that is, reduces in bus duct conductor copper bar and flows
The electric current crossed.The corresponding utilization ratio for reducing copper bar, causes the waste of material.How not influence assembly technology and show
On the premise of field anchor ear is installed, increase the area of dissipation of bus duct, the radiating effect of bus duct is improved, so as to improve leading for copper bar
Electrical efficiency, saving social resources, are always a great problem for perplexing bus duct industry.
Utility model content
The purpose of this utility model is to provide a kind of vertically arranged heat sinking chip bus duct, to solve the above-mentioned back of the body
The problem of being proposed in scape technology.
To achieve the above object, the utility model provides following technical scheme：A kind of vertically arranged heat sinking chip
Bus duct, including front shroud and back shroud, left plate and right plate, it is characterised in that：Set between the left plate and right plate
Be equipped with the conducting copper of parcel insulating materials, left plate and right plate with being provided with front shroud and back shroud before and after conducting copper,
Fin fixing hole is provided with the front shroud and back shroud, is provided between front shroud and back shroud and is close to side plate lateral surface
Fin, be provided with fixing hole on fin on fin.
It is preferred that, fixed between the front shroud and back shroud and left plate and right plate by rivet.
It is preferred that, the width of the front shroud and back shroud is set to 128mm, and left plate, right plate and conducting copper are thick
Degree sum is 25mm.
It is preferred that, the high setting of the fin is high 50mm.
It is preferred that, pass through fixing hole on fin fixing hole and fin between the fin and left plate and right plate
Fixed with self-tapping screw.
Compared with prior art, the beneficial effects of the utility model are：The utility model is not influenceing assembly technology and showed
On the premise of field anchor ear is installed, the area of dissipation of bus duct is considerably increased, the radiating effect of bus duct is effectively increased, changed
The bad radiating mode of conventional busbars groove radiating, the Novel bus duct made using the copper bar of same cross-sectional, can flow through than passing
The bigger electric current of bus duct that radiating mode of uniting makes, improves the electrical efficiency of conductor copper bar, has saved social resources.
