Abstract
The invention discloses an oil-immersed transformer convenient for heat dissipation. The oil-immersed transformer comprises an oil tank and a transformer body which is arranged inside the oil tank; a first heat dissipation assembly which is used for performing heat dissipation is detachably fixed on the lateral side of the oil tank; the first heat dissipation assembly comprises a first base and a plurality of heat dissipation parts which are fixed on the first base; every heat dissipation part is a hollow cylinder. According to the oil-immersed transformer convenient for the heat dissipation, every heat dissipation part of the first heat dissipation assembly is the hollow cylinder, an array is formed by the plurality of heat dissipation parts which are distributed on the first base, the array is of an omnidirectional structure, and accordingly the air flow resistance is low in comparison with a square or rectangular cooling fin, the in-out of the surrounding air flow is facilitated, the turbulent flow can be caused by the air flow impact on the cylinders, and accordingly the air flow is enhanced and the heat dissipation effect is enhanced and meanwhile the omnidirectional structure is large in surface area and accordingly the heat dissipation effect is good.
Description
Technical field
The present invention relates to a kind of transformer, be specifically related to a kind of oil-filled transformer of being convenient to heat radiation.
Background technology
Distribution transformer is one of visual plant in industrial and mining enterprises and civil buildings power supply-distribution system, and 10KV or 35KV network voltage are down to the 230/400V busbar voltage that user uses by it.Oil-filled transformer is one conventional in transformer, and this type of transformer generally comprises fuel tank, is arranged on the transformer body of fuel tank internal, fixed heat sink on the side of transformer body, the employing radiating fin heat radiation of this radiator.Along with present global warming, temperature is more and more higher, and particularly in summer, outdoor temperature can reach 40 degree sometimes, now often burns out transformer because radiating fin heat-sinking capability is not enough.
Summary of the invention
The invention provides a kind of oil-filled transformer of being convenient to heat radiation, solved because of the not enough problem that burns out transformer of radiating fin heat-sinking capability.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
An oil-filled transformer of being convenient to heat radiation, comprises fuel tank and is arranged on the transformer body of fuel tank internal; Detachable the first radiating subassembly being fixed with in order to heat radiation on the side of described fuel tank, described the first radiating subassembly comprises the first pedestal and is fixed on the some heat sinks on the first pedestal, described heat sink is hollow circular cylinder.
The heat sink of each hollow circuit cylinder body structure is vertical with the first pedestal fixing.
Described heat sink is evenly distributed on the first pedestal.
Described oil-filled transformer also comprises detachable the second radiating subassembly in order to heat radiation that is fixed on top of oil-tank.
Described the second radiating subassembly comprises the second pedestal and some radiating fins, and described radiating fin is fixed on the second pedestal, and respectively evenly.
Between described the second radiating subassembly and fuel tank, be also connected with heat pipe.
The invention has the beneficial effects as follows: 1, the heat sink of the first radiating subassembly of the present invention is hollow circular cylinder, the some heat sinks that are distributed on the first pedestal form an array, this array is omnidirectional's structure, for square or rectangle radiating fin, there is lower gas-flow resistance, contribute to the turnover of air-flow around, airflow strikes cylinder can cause turbulent flow, and then strengthens air-flow, strengthens radiating effect; Omnidirectional's structure has larger surface area simultaneously, and radiating effect is strong; 2, the first radiating subassembly adopts detachable fixing, and maintains easily; 3, top of oil-tank of the present invention also detachable fix the second radiating subassembly, can strengthen heat-sinking capability and can play again the effect of blocking simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the end view of the first radiating subassembly.
Fig. 3 is the vertical view of the first radiating subassembly.
Embodiment
Below in conjunction with Figure of description, the invention will be further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, a kind of oil-filled transformer of being convenient to heat radiation, comprises fuel tank 2 and is arranged on the transformer body 1 of fuel tank 2 inside.
On the side of fuel tank 2, be fixed with the first radiating subassembly 3 in order to heat radiation, adopt detachable fixing for the ease of safeguarding, the first radiating subassembly 3 as shown in Figures 2 and 3, comprise the first pedestal 31 and be fixed on the some heat sinks 32 on the first pedestal 31, heat sink 32 is hollow circular cylinder, hollow circular cylinder is vertical with the first pedestal 31 fixing, and the heat sink 32 of each hollow circuit cylinder body structure is evenly distributed on the first pedestal 31.
Above-mentioned heat sink 32 adopts the advantage of hollow circular cylinder as follows: the some heat sinks 32 that are distributed on the first pedestal form an array, this array is omnidirectional's structure, for square or rectangle radiating fin, there is lower gas-flow resistance, contribute to the turnover of air-flow around, airflow strikes cylinder can cause turbulent flow, and then strengthens air-flow, strengthens radiating effect, omnidirectional's structure has larger surface area simultaneously, and radiating effect is strong.
In order further to strengthen radiating effect, can block again high light and rainwater simultaneously, detachable the second radiating subassembly 4 being fixed with in order to heat radiation in fuel tank 2 tops, the second radiating subassembly 4 comprises the second pedestal 41 and some radiating fins 42, radiating fin 42 is fixed on the second pedestal 41, and respectively evenly, this radiating fin 42 adopts existing rectangular row or square, concrete structure is determined according to actual conditions, in order to ensure the heat transmission between fuel tank 2 and the second radiating subassembly 4, between the second radiating subassembly 4 and fuel tank 2, be connected with heat pipe 5 simultaneously.
In sum, the above-mentioned oil-filled transformer of being convenient to heat radiation is by the heat sink 32 of hollow circuit cylinder body structure, radiating effect is strong, and simultaneously at fuel tank 2 tops, detachable second radiating subassembly 4 of fixing can be strengthened heat-sinking capability and can play again the effect of blocking simultaneously, between two in conjunction with better heat-radiation effect.
More than show and described general principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
