Abstract

The utility model discloses a thermal insulation transformer, which comprises a transformer casing, an iron core and a coil winding, wherein the coil winding is wound around the iron core; the iron core and the coil winding are both arranged inside the transformer casing, and uniformly distributed heat conduction pipes are vertically arranged on the outer vertical surface of the transformer casing; the outer surface of the transformer casing is saw-toothed; thermal insulating layers are arranged on the outer surface of the transformer casing and the outer surface of the heat conduction pipes; the thermal insulating layers are made of thermal insulation aluminium foil coil material. When the sunlight irradiates the saw-toothed transformer casing, the thermal insulation transformer can reflect most of the sunlight, the thermal insulating layer can reflect the rest radiant heat, so that temperature rise of the transformer, caused by lighting, can be greatly reduced, the normal operation of the transformer is guaranteed, and the service life of the transformer is prolonged.

Description

Heat-insulation transformer

Technical field

The utility model relates to the potential device field, relates in particular to a kind of heat-insulation transformer.

Background technology

Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core.In electric equipment and radio-circuit, be commonly used for lifting voltage, matched impedance, safety isolation etc.In generator, no matter be that coil movement is passed through magnetic field or Movement in Magnetic Field by fixed coil, all can be in coil induced potential, these two kinds of situations, the value of magnetic flux is all constant, but with the magnetic flux quantity of coil intersecting chain, change is arranged, this is the principle of mutual induction.Transformer is exactly that a kind of undesirable mutual electromagnetic inductance of utilizing is answered, voltage of transformation, the device of electric current and impedance.The function of transformer mainly contains: voltage transformation; Current transformation, impedance transformation; Isolation; Voltage stabilizing (magnetic saturation transformer) etc.According to different requirements; transformer can be arranged on indoor or outdoor; and the housing of transformer inevitably can be subject to the acute irradiation of sunlight while being arranged on open air; temperature in transformer shell can sharply raise; thereby cause the protection fluid in housing to overflow; affect the normal operation of the parts such as iron core and coil, and then affect overall work state and the useful life of transformer.

The utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of heat insulation good transformer.

For achieving the above object, the utility model provides following technical scheme: a kind of heat-insulation transformer, comprise transformer shell, iron core and coil windings, the winding of described coil windings parcel is on iron core, described iron core and coil windings all are arranged on transformer shell inside, on the external facade of described transformer shell, be evenly equipped with vertically disposed heat pipe, described transformer shell external surface indentation, transformer shell external surface and heat pipe outer surface are equipped with thermal insulation layer, and described thermal insulation layer consists of the aluminium foil thermal insulating coiled material.

By adopting technique scheme, when solar irradiation is mapped to the transformer shell of indentation, can reflect away most illumination, reflecting effect is obvious, and thermal insulation layer adopts aluminum foil coiled material, have the functions such as heat-insulation and heat-preservation, waterproof, protection against the tide, the absorptivity at sunshine of aluminium foil thermal insulating coiled material is that solar radiation absorbility factor is extremely low, has remarkable heat preservation and insulation, can reflect away the radiant heat more than 93%, alleviate transformer and raise because shining upon the temperature produced, guarantee the normal operation of transformer, extend the useful life of transformer.

The utility model further is set to: on described transformer shell, be provided with ventilation unit, described ventilation unit comprises ventilating opening and is arranged on the fan on ventilating opening.

By adopting technique scheme, when transformer is arranged on when indoor, can, by ventilation unit is set on transformer shell, comprise ventilating opening and fan, rotating fan increases the temperature in intake reduction transformer, also the heat of a part in transformer is left by ventilating opening simultaneously.

The utility model further is set to: described heat pipe consists of copper aluminium heat sink compound.

By adopting technique scheme, in transformer work, iron core and coil heating have heated transformer oil, the transformer oil of heating rises transformer oil and enters radiating tube simultaneously, through the cooled transformer oil of radiating tube, sink to entering the bottom of heat pipe, employing copper and aluminium are that the copper aluminium heat sink compound of original material has good heat-conductive characteristic, thermal diffusivity and corrosion resistance, form the circulation cooling passage of stability and high efficiency, make transformer work keep stable.

The utlity model has following advantage: when solar irradiation is mapped to the transformer shell of indentation, can reflect away most illumination, by thermal insulation layer, reflect away remaining radiant heat again, greatly alleviating transformer raises because of the temperature that illumination produces, guarantee the normal operation of transformer, extended the useful life of transformer.
