The high-efficiency transformer with the unpowered fan can improve the circulation of the ambient air of the transformer and can achieve the goal of cooling the transformer.

Description

A kind of high efficiency is unpowered blower fan transformer

Technical field

The utility model relates to the technical field of transformer heat radiation aspect, refers in particular to the unpowered blower fan transformer of a kind of high efficiency.

Background technology

Under the usual condition, because of no-load loss and load loss, tend to give out a large amount of heat during transformer work, air themperature is raise, and the generation of its heat energy is bigger to the influence of transformer, as deals with operating efficiency and the useful life that tends to reduce transformer improperly.So when the inside at transformer-cabinet or motor house of transformer limitation, it is very important that its Heat-treatment Problem just becomes, especially in summer, its influence is bigger, at this moment tends to adopt radiator to carry out radiating treatment, keeps transformer energy operate as normal.And along with development of science and technology, in recent years, multiple radiator has appearred in the society, but consider the consumption of the energy, it is ideal that unpowered blower fan is used for radiating treatment, but also there are a lot of problems in general unpowered blower fan on the market now, for example when not having natural wind or gentle breeze, general its operating efficiency of unpowered blower fan is not high, even can't drive, for example Chinese utility application prospectus CN201160229 discloses a kind of unpowered blower fan solar-electricity auxiliary system, blower fan solar-electricity auxiliary system that this is unpowered when bright and clear its operating efficiency just than higher, but when its in following time of environment that insufficient light or dull thread shine, its operating efficiency just is difficult to the effect that reaches desirable, also has this solar-electricity auxiliary system electrical maintenance, change trouble, and production cost is also high.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and the unpowered blower fan transformer of a kind of good heat dissipation effect, high efficiency, long service life is provided.

For achieving the above object, technical scheme provided by the utility model is: a kind of high efficiency is unpowered blower fan transformer, it includes transformer body, transformer-cabinet, wherein, it also includes unpowered blower fan, waffle slab, wherein, unpowered blower fan by rack in the open top of transformer-cabinet, waffle slab is assemblied in the bottom port of transformer-cabinet, and transformer body is fixedly mounted in the transformer-cabinet by waffle slab, and unpowered blower fan includes top cover, turbine, wherein, turbine cartridge fits on the frame, and turbine is to be plugged together mutually by the multi-disc turbo blade to form, and top cover is located at the top of turbine.

Described turbo blade is an arc shaped blade.

After the utility model has adopted such scheme, during transformer work, the turbine rotation that is promoted unpowered blower fan by the hot-air in the case is discharged air, when the air in the turbine is detached turbine, further impel the interior hot-air of case up to replenish, the fresh cold air of outside is replenished into from the transformer-cabinet bottom, and, this unpowered blower fan also can utilize natural wind to promote the turbine rotation, thereby strengthen the radiating effect of transformer, therefore, the utility model can improve the circulation of transformer surrounding air, reaches the purpose that makes the transformer cooling heat dissipation.

Description of drawings

Fig. 1 is a front view of the present utility model.

Fig. 2 is an end view of the present utility model.

Fig. 3 is the structural representation of the unpowered blower fan of the utility model.

Embodiment

Below in conjunction with institute's drawings attached the utility model is done a new step explanation, preferred embodiment of the present utility model includes transformer body 1, transformer-cabinet 2, unpowered blower fan 3, waffle slab 4, wherein, unpowered blower fan 3 is assemblied in the open top of transformer-cabinet 2 by frame 5, waffle slab 4 is assemblied in the bottom port of transformer-cabinet 2, transformer body 1 is fixedly mounted in the transformer-cabinet 2 by waffle slab 4, wherein, described unpowered wind 3 includes top cover 6, turbine 7, wherein, turbine 7 is assemblied on the frame 5, and turbine 7 is to be plugged together mutually by multi-disc turbo blade 8 to form, and the turbo blade 8 that the utility model adopted is arc shaped blade, and it is quite frivolous, this arc shaped blade is the optimum through the calculating of science, even faint gentle breeze also can make turbo blade 8 rotate, thereby drives turbine 7 rotations, its ventilation efficiency height, simultaneously, top cover 6 is located at the top of turbine 7, and then guarantees will not allow rainwater invade under unpowered blower fan 3 in working order.When transformer is worked, air themperature in the transformer-cabinet 2 raises, hot-air rises, the air that rises then promotes the turbo blade 8 of unpowered blower fan 3 and makes turbine 7 rotations, the running of turbine 7 produces centrifugal force discharges air, when the air in the turbine 7 is detached turbine 7, just form low-pressure area under the turbine 7, thereby generation stack effect, further impel the hot-air in the transformer-cabinet 2 up to replenish, the fresh cold air of outside is replenished into from the waffle slab 4 of transformer-cabinet 2 bottoms, and unpowered blower fan 3 of the present utility model also can utilize natural wind to promote the rotation of turbine 7, and turbine 7 rotates soon more, air flows in its transformer-cabinet 2 is just fast more, thereby strengthens the radiating effect of transformer like this.Therefore, the utility model can improve the circulation of transformer surrounding air, reaches the purpose that makes the transformer cooling heat dissipation, thereby the assurance transformer is being worked under normal temperature, like this, and under identical condition of work, transformer's life span is prolonged, and its overload capacity is also strengthened.In a word, the utility model energy-conserving and environment-protective, unpowered blower fan is durable in use, production cost is low, and changes simply, is worthy to be popularized.

The embodiment of the above is the preferred embodiment of the utility model only, is not to limit practical range of the present utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in protection range of the present utility model.
