Description
Technical field
The utility model relates to field of electrical equipment, specifically a kind of transformer.
Background technology
Transformer utilizes 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 buck/boost, matched impedance, Secure isolation etc.In generator, be no matter coil movement by magnetic field or Movement in Magnetic Field by fixed coil, all can in coil induced potential, these two kinds of situations, the value of magnetic flux is all constant, but has variation with the magnetic flux quantity of coil intersecting chain, and this is the principle of mutual induction.Transformer is exactly that one utilizes undesirable mutual electromagnetic inductance to answer, 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.
Loss is produced always during transformer electric energy transmitting, 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 inside transformer perfusion transformer oil to take away this part heat, this part heat is circulated in the heat pipe of transformer case outside by conduction oil and dispels the heat, when peak of power consumption in summer, transformer temperature sharply raises, too high temperature makes again transformer internal resistance raise, further aggravation heating, transformer work is made relatively to become unstable, therefore heat radiation is a large key element of transformer steady operation.Existing transformer otherwise radiating effect undesirable, or cost is too high, is badly in need of a kind of good heat dissipation effect now, transformer with low cost.
Utility model content
The purpose of this utility model is to provide that a kind of structure is simple, the transformer of good heat dissipation effect, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of transformer, comprise shell and magnetic core, described shell is by Shell Plate, evacuated panel and inner hull composition, described evacuated panel is positioned in the middle of Shell Plate and inner hull, on shell, two ends, left and right symmetry offers some ventilation holes, all dust excluding plate is installed in described ventilation hole, described magnetic core is located at the inside of shell, magnetic core comprises upper arm, linking arm and underarm, described upper arm and underarm are located at the two ends up and down of linking arm respectively, drum stand is equipped with outside upper arm and underarm, described drum stand offers some through holes, drum stand on upper arm is provided with armature winding, drum stand on underarm is provided with secondary winding, insulating part is provided with between described armature winding and secondary winding.
As further program of the utility model: described insulating part is writing board shape.
As further program of the utility model: the cross section of described upper arm, linking arm and underarm is circular or square, and the cross-sectional area of upper arm, linking arm and underarm is equal.
As the utility model further scheme: described magnetic core is iron core or copper core.
Compared with prior art, the beneficial effects of the utility model are: between Shell Plate and inner hull, arrange evacuated panel, can effectively completely cut off sunlight be exposed to the sun lower shell plate produce heat be delivered in transformer, effectively can completely cut off the noise transmission of transformer Instrumental generation to extraneous simultaneously, shell is provided with some groups of corresponding ventilation holes, cross-ventilation can be formed, accelerate heat radiation, dust excluding plate is provided with in ventilation hole, while heat radiation, also prevent dust from entering enclosure interior, the useful life of transformer can be increased, by on upper arm that armature winding and secondary winding are configured in magnetic core respectively and underarm, the line bag width formed is longer, the number of plies is less, thus identical winding turns, required total winding length shortens, save wire rod consumption, reduce material cost.Simultaneously because the number of plies tails off, line bag is thinning, improve the heat radiation of transformer, significantly reduce the temperature rise of transformer whole, also reduce the whole height of transformer, outside upper arm and underarm, be equipped with drum stand, drum stand offers some through holes, not only play the effect making armature winding and secondary winding and the electric insulation between upper arm and underarm, also guarantee ventilation and the creepage distance of magnetic core and armature winding and secondary winding, optimize thermolysis further.The utility model structure is simple, and volume is little, long service life, through the combination of multiple radiator structure, make radiating effect good, also do not need by external equipment, economize on resources, reduce production cost, meet the user demand of people, good market prospects, be easy to promote.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of transformer, comprise shell 1 and magnetic core 2, described shell 1 is by Shell Plate 3, evacuated panel 4 and inner hull 5 form, described evacuated panel 4 is positioned in the middle of Shell Plate 3 and inner hull 5, can effectively completely cut off sunlight be exposed to the sun lower shell plate 3 produce heat be delivered in transformer, effectively can completely cut off the noise transmission of transformer Instrumental generation to extraneous simultaneously, on shell 1, two ends, left and right symmetry offers some ventilation holes 14, in described ventilation hole 14, dust excluding plate 15 is all installed, cross-ventilation can be formed, accelerate heat radiation, dust excluding plate 15 is provided with in ventilation hole, while heat radiation, also prevent dust and enter housing 1 inside, avoid housing 1 internal dust too much, impact uses, the useful life of transformer can be increased.
