Description

A kind of heat radiation bus duct

Technical field

This utility model relates to bus duct field, particularly to the bus duct of a kind of heat radiating type.

Background technology

Growing along with modernization construction, the utilization rate of bus duct is more and more higher, thus the quality improving bus duct is very urgent. Current bus duct operationally can heating in various degree, when temperature can produce a series of bad phenomenon after raising: (1) temperature raises, and directly influences the loss (increasing) of electric energy; (2) temperature raises, and insulant is aging soon, and the service life of bus duct shortens; (3) bus duct internal temperature raises, and voltage drop strengthens; (4) temperature raises, and after metallic conductor is heated, stress starts lax thus reducing mechanical strength, makes the mechanical strength of bus duct also decline to some extent; (5) temperature raise, cause surrounding insulant equipment quickening aging, as with bus duct at the adjacent electric wire taken or transfer or electrical insulation supporting piece etc., even easily caused by fire incident. Bus duct in the market can increase fin at shell place, but once breaking out of fire accident, or can not play the generation of fire containment timely, so exploitation one can be dispersed heat in time and in case of emergency can play fireproof bus duct and be particularly important when busbar works.

Utility model content

The purpose of this utility model is to provide a kind of heat radiating type can get well and can play the bus duct of urgent flameproof effect.

Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of heat radiation bus duct, including bus duct body and copper bus-bar, it is characterized in that, the at least two arranged outside of described bus duct body has radiating fin, described radiating fin is outward extended with the radiating fin perpendicular with copper bus-bar position, and it is provided with substrate between described radiating fin and bus duct body, described substrate is provided with some thermal holes, is provided with between described adjacent thermal hole and is available for the fire-proof holes that flame barrier is filled.

By adopting technique scheme, it is provided by thermal hole, utilize the principle that cold air decline hot-air rises, therefore the radiating fin of this creation is as capwise, this mode can drive cold air and radiating fin to carry out heat exchange, heated air upwards convection current, cold air below bus duct is made also upwards to supplement, this method can make cold air flow through between each radiating fin, take away heat energy produced by bus duct body, effectively stop thermal energy conduction, temperature-raising characteristic to reduce top and bottom shows, and it is provided with flame barrier, once breaking out of fire, flame barrier can play fireproof effect, avoid spreading of the condition of a fire.

Of the present utility model be further disposed in, at least one arranged outside of described bus duct body has thermal insulation board.

By adopting technique scheme, owing to radiating fin is densely arranged setting, serve installation people by the setting of thermal insulation board can convenient being operated in the middle of installation process on thermal insulation board.

Of the present utility model be further disposed in, described flame barrier includes anti-Pyroxylin and is arranged on the dividing plate outside anti-Pyroxylin, and described dividing plate is connected with thermal hole.

By adopting technique scheme, the specifically created chamber placed for flame barrier is served by the setting of dividing plate, and dividing plate is connected with thermal hole, serve once breaking out of fire, flame can be contacted with flame barrier by thermal hole rapidly, thus the very first time can play stops spreading of flame.

Of the present utility model be further disposed in, the two sides of described fixing insertion are provided with supple buffer layer.

By adopting technique scheme, being provided by supple buffer layer, serving will not because of the friction in assembling thus what cause scratches between fixing insertion and copper bus-bar sheet.

Of the present utility model be further disposed in, the both sides of described copper bus-bar are provided with protection catch.

By adopting technique scheme, serve protection by protecting the setting of catch to serve the both sides for copper bus-bar, add the degree of protection of copper bus-bar.

Of the present utility model being further disposed at is provided with waterproof pad in, described copper bus-bar and shell junction.

By adopting technique scheme, it is provided with waterproof pad, effectively prevent because water penetration is to bus duct inner end, cause electric short circuit, cause bus to explode.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail.

Embodiment 1:

With reference to accompanying drawing 1, a kind of heat radiation bus duct, including bus duct body 1 and copper bus-bar 2, the column that bus duct body 1 is elongated, bus duct body 1 just has four sides, two sides are provided with substrate 3 wherein, substrate 3 is outward extended with the radiating fin 4 perpendicular with copper bus-bar 2 position, it is provided with thermal hole 31 on the substrate 3, thermal hole 31 runs through the height of whole substrate 3, the shape of cross section of thermal hole 31 is circular, it is provided by thermal hole 31, utilize the principle that cold air decline hot-air rises, therefore the radiating fin 4 of this creation is as capwise, this mode can drive cold air and radiating fin 4 to carry out heat exchange, heated air upwards convection current, cold air below bus duct is made also upwards to supplement, this method can make cold air flow through between each radiating fin 4, take away heat energy produced by bus duct body 1, effectively stop thermal energy conduction, temperature-raising characteristic to reduce top and bottom shows.
