Description

Transformer

Technical field

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

During the transformer electric energy transmitting, produce always loss, this loss mainly contains copper loss and iron loss, copper loss and iron loss all can produce amount of heat, general civilian transformer all adopts at the inner perfusion of transformer transformer oil and takes away this part heat, this part heat is circulated to by conduction oil in the heat pipe of transformer case outside and dispels the heat, in summer during peak of power consumption, transformer temperature sharply raises, too high temperature makes again the transformer internal resistance raise, further aggravation heating, make transformer work relatively become unstable, therefore heat radiation is a large key element of transformer steady operation.

The utility model content

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

For achieving the above object, the utility model provides following technical scheme: a kind of 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, the oilhole that is arranged on the transformer shell top and the bottom is passed at the two ends up and down of described heat pipe, described every pair is positioned on the corresponding oilhole in transformer shell top and the bottom and is provided with condenser pipe, 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, in transformer work, transformer oil has been heated in iron core and coil windings heating, the transformer oil of heating rises transformer oil and enters condenser pipe simultaneously, through the cooled transformer oil of condenser pipe, sink to entering the bottom of heat pipe, with this circulation cooling passage that forms stability and high efficiency, radiating rate more originally improves a lot, and makes transformer work keep stable; In addition, when transformer is arranged on when indoor, can comprise ventilating opening and fan by ventilation unit is set on transformer shell, rotating fan increases intake and reduces the temperature in transformer, also the heat of a part in transformer is left by ventilating opening simultaneously.

The utility model further is set to: described transformer shell external surface is provided with thermal insulation layer, and described thermal insulation layer consists of the aluminium foil thermal insulating coiled material.

By adopting technique scheme, the transformer operated by rotary motion out of doors or indoor, the housing of outdoor transformer inevitably can be subject to the acute irradiation of sunlight, make the temperature in housing sharply raise, thereby cause the protection oil spill in housing to go out, affect the operating state of the parts such as iron core and coil, and then affect useful life of transformer, and aluminum foil coiled material has heat-insulation and heat-preservation, waterproof, the functions such as 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%, alleviating transformer raises 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: described condenser pipe consists of copper alloy.

By adopting technique scheme, copper alloy is to take the alloy that fine copper adds one or more other elements to be formed as matrix, and the conduction of copper alloy, thermal conductivity are very good, very high to the resistance to corrosion of large G&W, processing characteristics, plasticity are fine, easy hot and cold shaping; With the condenser pipe that copper alloy is made, carry out transformer oil heat radiation and the good refrigeration effect in cooling and circulation heat conduction pipe.

The utlity model has following advantage: by the setting of condenser pipe and ventilation unit, the heat produced in the transformer that left fast; And the setting by thermal insulation layer reflects away most radiant heat, alleviate transformer because the temperature that illumination produces raises, guaranteed the normal operation of transformer, extended the useful life of transformer.
