Abstract
The invention discloses an oil-immersed transformer oil tank heat dissipation structure. The oil-immersed transformer oil tank heat dissipation structure comprises an oil tank body, a transformer body heating body which is arranged in the oil tank body and a plurality of hollow heat dissipation fins which are formed by extending the oil tank body outwards. Heat guide oil is filled among the heat dissipation fins and the transformer body heating body, heat guide division plates are arranged in the heat guide oil which is filled among the transformer body heating body and the heat dissipation fins, the heat guide division plates are attached to the hollow heat dissipation fins, an upper oil hole and a lower oil hole are formed at the upper end of the heat guide division plate and the lower end of the heat guide division plate, and the upper oil hole and the lower oil hole correspond to the heat dissipation fins. Due to the fact that heat guide division plates are arranged between the transformer body heating body and the hollow heat dissipation fins to divide a crosswise temperature field into an upper passage and a lower passage and to divide a lengthways temperature field into an upper passage and a lower passage, and therefore oil flow thermal power is increased, and heat dissipation efficiency is improved to a great extent. The oil-immersed transformer oil tank heat dissipation structure has the advantages of being simple in structure, easy to achieve, reliable, safe and good in heat dissipation performance.
Description
Technical field
The present invention relates to a kind of oil-filled transformer, relate in particular to a kind of oil tank for oil immersion type transformer radiator structure.
Background technology
As everyone knows, transformer is the main and important parts of power supply changeover device, it is in the process of operation, due to flowing and the existence of electromagnetic field of each coil-conductor electric current, can produce electric energy loss, it is mainly load loss, no-load loss and supplementary load loss, these losses will be converted into heat and pass to surrounding medium, thereby make the device body heating of transformer, temperature raises, therefore for the transformer as the power transmission and transformation substantial equipment, heat abstractor often to be set the electric energy loss heat is in time shed, to guarantee the normal operation of transformer.
Several hollow radiating fins that traditional oil tank for oil immersion type transformer radiator structure comprises device body heater and is arranged at device body heater periphery, filling heat-conductive oil between radiating fin and device body heater, rely on heat buoyancy as the heat radiation power of conduction oil, utilize the motion of conduction oil to dispel the heat, but this kind radiator structure, in the conduction oil motion process, due to two not well-proportioned natural temperature field effects of being interweaved up and down, the motion of described conduction oil is very disorderly, causes radiating effect very poor.
Summary of the invention
The object of the present invention is to provide a kind of oil tank for oil immersion type transformer radiator structure, its have simple in structure, be easy to realize, good heat dissipation effect and safe and reliable characteristics.
The objective of the invention is to be achieved through the following technical solutions:
A kind of oil tank for oil immersion type transformer radiator structure, it comprises tank body of oil tank, be arranged at the interior device body heater of tank body of oil tank and several hollow radiating fins of tank body of oil tank extension, filling heat-conductive oil between described radiating fin and device body heater, wherein, be provided with heat conduction baffle in conduction oil between described device body heater and radiating fin, the corresponding radiating fin of described heat conduction baffle leave upper and lower oilhole in upper and lower end.
Especially, the described heat conduction baffle hollow radiating fin setting that reclines.
Especially, described heat conduction baffle is steel plate, and thickness is 2cm.
Beneficial effect of the present invention is that described oil tank for oil immersion type transformer radiator structure is provided with heat conduction baffle between device body heater and hollow radiating fin, horizontal and vertical temperature field is all cut told the road, up and down, and is not only simple in structure, is easy to realize; And safe and reliable, good heat dispersion is arranged.
