Description

Transformer radiator tube
Technical field
The utility model belongs to transformer field of radiating, particularly transformer radiator tube.
Background technology
When oil-filled transformer runs, the inner parts such as winding, iron core produce loss, loss is converted to heat and passes to oil tank wall by the heat transfer of transformer oil and convection action, transformer operationally time can cause winding, iron core, oil tank wall and oil surface temperature to rise, but temperature rise directly affects the life-span of winding insulation material, so the temperature rise of control transformer just determines the life-span of transformer.The radiating mode that present routine adopts adopts oil pipe naturally to cool and cooling forced by fan, and the mode adopting fin heat radiation is surrounding fin being distributed in transformer oil tank wall.Such mode not only increases the cost of manufacture of floor space and fuel tank, and along with present global warming, temperature is more and more higher, particularly in summer, outdoor temperature can reach 40 degree sometimes, now often burns out transformer because radiating fin heat-sinking capability is not enough.
Utility model content
The purpose of this utility model is to provide one and can carries out pressure cooling by running water and solved because of the hypodynamic problem of radiating fin heat radiation energy.
In order to achieve the above object, the transformer radiator tube that the utility model provides, comprise radiating tube body, described radiating tube body is provided with oil-out, oil-in, water inlet and delivery port, described oil-in is communicated with by heat exchanger tube in radiating tube body with oil-out, described heat exchanger tube becomes spiral plate-like in radiating tube body, described water inlet and delivery port are connected to the two ends of radiating tube body, described oil-in and oil-out are connected on oil tank of transformer respectively by flange arrangement, described water inlet and delivery port connect running water pipe, the bottom of described radiating tube body is provided with blowdown pipe.
The transformer radiator tube of this programme when in use, the water inlet of radiating tube body and delivery port are connected on water supply pipe, there is provided running water as the cooling water of transformer by running water pipe, oil-in and oil-out are connected on oil tank of transformer by flange arrangement, the transformer oil heat in heat exchanger tube constantly taken away by running water, even if in the summer of sweltering heat, can avoid that fuel tank temperature is too high causes transformer damage.
The utility model has the advantage of: utilize running water to exchange heat pipe and cool, because running water is one-way flow, water at low temperature endlessly can be provided, the transformer oil heat in heat exchanger tube constantly taken away by logical running water, because running water is generally lower than the water of normal temperature, even if in the summer of sweltering heat, also the running water by flowing cools transformer oil, thus effectively avoid too high situation transformer being caused to damage of fuel tank temperature, if increase the efficiency of heat exchange, use the water source that can pass in running water pipe through cooling process.
As preferred scheme, the outer wall of described radiating tube body is provided with the lamination for increasing radiating tube bulk strength, and be strengthen the mechanical strength of radiating tube body by the object of lamination, prevent wind-force larger area, blast is to the wearing and tearing of radiating tube body surface.
As preferred scheme, described heat exchanger tube is aluminium alloy heat exchange tube, because aluminium alloy heat exchange tube is convenient to manufacture, and also has higher heat transfer and anti-corrosion capability.
As preferred scheme, described delivery port is provided with spray arm, spray arm arranges shower nozzle, and spray between arm and shower nozzle and be provided with force (forcing) pump, delivery port arranges spray arm, compensate for radiating tube to lower the temperature to oil tank of transformer, the shortcoming can not lowered the temperature to the annex of transformer end face.Operationally wait, use control circuit to come to open and close force (forcing) pump to control as required, make force (forcing) pump in hotter sky in summer, be interrupted as required and open, realize lowering the temperature to the annex of transformer summer.
Finally, described shower nozzle is multiple, and multiple shower nozzle is equidistantly arranged on the edge of transformer end face.By the edge being arranged in transformer equidistant for shower nozzle, lower the temperature through the annex of mode to transformer end face spraying water smoke.
Accompanying drawing explanation
Fig. 1 is the structural representation of transformer radiator tube;
Fig. 2 is the right view of Fig. 1.
Reference numeral is enumerated: oil tank of transformer 1, radiating tube body 2, water inlet 3, delivery port 4, oil-in 5, oil-out 6, lamination 7, blowdown pipe 8, spray arm 9, shower nozzle 10, heat exchanger tube 11, force (forcing) pump 12.
Embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Transformer radiator tube as depicted in figs. 1 and 2, comprise on radiating tube body 2, radiating tube body 2 and be provided with oil-out 6, oil-in 5, water inlet 3 and delivery port 4, oil-in 5 is communicated with by heat exchanger tube 11 in radiating tube body 2 with oil-out 6, heat exchanger tube 11 becomes spiral plate-like in radiating tube body 2, water inlet 3 and delivery port 4 are connected to the two ends of radiating tube body 2, oil-in 5 and oil-out 6 are connected on oil tank of transformer 1 respectively by flange arrangement, water inlet 3 and delivery port 4 connect running water pipe, and the bottom of radiating tube body 2 is provided with blowdown pipe 8.
Utilize running water to exchange heat pipe to cool, because running water is one-way flow, water at low temperature endlessly can be provided, the transformer oil heat in heat exchanger tube 11 constantly taken away by logical running water, because running water is generally lower than the water of normal temperature, even if in the summer of sweltering heat, also the running water by flowing cools transformer oil, thus effectively avoid too high situation transformer being caused to damage of fuel tank temperature, if increase the efficiency of heat exchange, use the water source that can pass in running water pipe through cooling process.
