Abstract

The utility model discloses a transformer which comprises a transformer shell, an iron core placed in the transformer shell, a coil winding on the iron core, a cooling pipeline placed on the transformer shell, and a radiating device placed on the outer wall of the transformer shell. The radiating device is composed of an exhaust fan, a heat conduction pipe and radiating fins. According to the transformer, vegetable oil is used as a cooling agent, even though the cooling agent is leaked, the environment can not be polluted, and environmental protection is facilitated. In addition, the radiating device is arranged on the outer wall of the shell, the radiating device can exhaust heat generated inside the shell out of the transformer quickly, the phenomenon that insulation ageing of the coil and the iron core is accelerated due to the too high temperature is avoided, and therefore the service life of the transformer is prolonged.

Description

A kind of transformer

Technical field

The utility model relates to a kind of transformer.

Background technology

Transformer is that a kind of undesirable mutual electromagnetic inductance of utilizing is answered, voltage of transformation, and the device of electric current and impedance, in electric equipment and radio-circuit, transformer is commonly used to lifting voltage, matched impedance.Transformer is when operation, its coil and iron core can produce copper loss and iron loss, these losses will become heat energy, make the iron core of transformer and coil temperature increase, if the temperature of coil and iron core surpasses permissible value for a long time, can make insulation gradually lose mechanical elasticity and make ageing of insulation.Therefore a kind of exploitation of the transformer with good heat radiating device is necessary.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of transformer with good heat radiating device.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:

A kind of transformer, comprise transformer shell, be positioned at transformer shell iron core, be wrapped in coil on iron core, be positioned at the cooling pipe on transformer shell and be positioned at the heat abstractor on transformer shell outer wall, described heat abstractor is comprised of ventilating fan, heat pipe and fin.

Further, described iron core is formed by silicon steel plate stacking, and the thickness of described every silicon steel sheet is 0.1 ~ 0.2mm.

Further, described iron core is E shape.

Further, in described cooling pipe, cooling agent is housed, described cooling agent is vegetable oil.

Further, described cooling pipe is ring-like pipeline.

Beneficial effect: than prior art, the utility model adopts vegetable oil as cooling agent, even if cooling agent leakage occurs not to pollute the environment yet, be conducive to environmental protection, the utility model arranges heat abstractor at the outer wall of housing in addition, the heat that heat abstractor can produce enclosure interior is fast discharged transformer, thereby can not make coil and iron core occur because excess Temperature makes insulation accelerated aging phenomenon, and then has extended the useful life of transformer.

Fig. 2 is the vertical view of the utility model transformer.

Embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.

As shown in Figure 1, transformer of the present utility model, comprise transformer shell 1, be positioned at the iron core 2 of transformer shell 1, be wrapped in the coil 3 on iron core 2, be positioned at the cooling pipe 4 on transformer shell 1 and be positioned at the heat abstractor 5 on transformer shell 1 outer wall, described heat abstractor 5 is by ventilating fan, heat pipe and fin form, the loss heat energy that the heat that the inner every layer of silicon steel sheet eddy current of housing 1 produces and coil 3 and iron core 2 produce, after the cooling agent through in cooling pipe 4 absorbs, by heat abstractor 5 by the dissipation of heat in cooling water pipe in air, thereby can not make coil 3 and iron core 2 occur because excess Temperature makes the phenomenon of ageing of insulation, and then extended useful life of transformer, iron core 2 is formed by silicon steel plate stacking, can reduce so loss that every layer of eddy current bring and the heat of generation, the thickness of every silicon steel sheet is 0.1 ~ 0.2mm, iron core 2 is E shape, in cooling pipe 4, cooling agent is housed, described cooling agent is vegetable oil, even if cooling agent leakage occurs not to pollute the environment yet, be beneficial to environmental protection, cooling pipe 4 is ring-like pipeline.

In sum, this transformer with good heat radiating device will have good promotional value and market adaptability.
