Abstract
The utility model discloses a bus bar with a heat dissipation function, which comprises a bus bar conductor (1). A heat dissipation layer (2) formed by a radiation heat dissipation paint is coated outside the bus bar conductor (1). The radiation heat dissipation paint of the heat dissipation layer (2) is formed by a nano material with higher reflectivity for visible light and near infrared light, higher thermal infrared emissivity, high temperature stability and excellent physical property, chemical property and construction performance so as to fulfill the aim of efficiently radiating, reducing the temperature and insulating heat.
Description
Technical field
The utility model relates to a kind of bus, and the particularly a kind of bus that can realize the cooling and insulating function belongs to the high-current switch equipment technical field.
Background technology
Bus is meant the connection of voltage power distribution equipments at different levels in electric substation, and being connected of electric equipment such as transformer and corresponding power distribution equipment, and mostly adopts the plain conductor or the twisted wire of rectangle or circular cross-section, and this is referred to as bus.The effect of bus is to compile, distribute and transmit electric energy.
Expose at outdoor bus and will often be subjected to wind, rain, snow, Exposure to Sunlight, erosion such as freezing, these factors are all impelled busbar joint accelerated oxidation, corrosion, so just make the contact resistance of joint increase, and bus temperature when operation will raise.
Too high, the overheated meeting of the temperature of bus causes ageing of insulation even burns insulating material, causes short trouble and heavy economic losses.The joint can make contact resistance increase because temperature increases, thus vicious circle.When serious, on fire also is very normal phenomenon.
The temperature of bus raises unavoidable, therefore need lower the temperature the security of operation of protection bus at bus.
The utility model content
Technical problem to be solved in the utility model provides a kind of bus with heat sinking function, and its heat that can quicken bus voluntarily distributes to the external world, reaches the purpose that reduces temperature rise.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of bus with heat sinking function, comprise bus-bars conductor, and the heat dissipating layer of heat loss through radiation coating formation is arranged at the outside coating of described bus-bars conductor.
The thickness of described heat dissipating layer is 0.03-0.3mm.
Heat loss through radiation coating is behind film-forming on the bus-bars conductor, at first film coated surface forms good heat reflection interface, its heat reflectivity reaches 60%-90% in wider frequency, and the heat that face absorbs only is 10%-40%, and the coating face keeps off most heat at the coating skin with the form of reflection.When intensification was accumulated in the face heat absorption, the heat absorption interface will be to film external space heat loss through radiation.
Because the material of heat loss through radiation coating and the effect of rete inner structure, the thermal radiation emissivity of face can reach about 90%, can launch the heat energy that the face heat absorption is accumulated in the mode of radiation.
Heat loss through radiation coating has higher nano material to visible light and near infrared light reflectivity, higher thermal infrared emissivity, high-temperature stability, good physical property, chemical property and workability and constitutes, thereby reaches the purpose of high efficient radiation cooling and insulating.
Heat loss through radiation coating can be launched away heat on the bus-bars conductor with 8-13.5 mum wavelength form, the vacuum cavity group who reduces the body surface temperature and form with the nano-hollow ceramic fine bead in the photopolymer layer, form effective heat shield, thereby reach the effect of cooling and insulating.Heat loss through radiation coating play radiation cooling heat insulation in, good self-cleaning, anti-corrosive properties, water proofing property, fire line, insulating properties, antiacid alkali are also arranged.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, a kind of bus with heat sinking function comprises bus-bars conductor 1, at the outside coating of described bus-bars conductor 1 heat loss through radiation coating is arranged, and heat loss through radiation coating forms the heat dissipating layer 2 of bus.
Should be at the extraordinary heat radiation coating of bus-bars conductor 1 appropriate location brushing suitable thickness, will there be bigger heat-dissipating space the brushing position, can not be the conductive surface of close and opposite, and the brushing thickness requirement is between 0.03 to 0.3mm, and brushing is wanted evenly.
Heat loss through radiation coating can form effective heat shield, thereby reaches the effect of cooling and insulating, and it launches away heat on the bus-bars conductor with 8-13.5 mum wavelength form.
The radiating and cooling amplitude of bus is as shown in the table:
| The bus matrix | 40℃ | 60℃ | 80℃ | 100℃ | 200℃ | 300℃ | 400℃ |
| Reduce the temperature difference | 6℃ | 15℃ | 23℃ | 30℃ | 50℃ | 70℃ | 85℃ |
The foregoing description limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection range of the present utility model.
Claims (2)
1. the bus with heat sinking function comprises bus-bars conductor (1), it is characterized in that: the heat dissipating layer (2) that the formation of heat loss through radiation coating is arranged at the outside coating of described bus-bars conductor (1).
2. the bus with heat sinking function according to claim 1 is characterized in that: the thickness of described heat dissipating layer (2) is 0.03-0.3mm.
