Abstract
The utility model discloses a transformer which comprises a casing, a fan, a bottom plate, a coil component, and a controlling device connected with the coil component, wherein, the bottom plate is positioned in the casing; the coil component is connected on the bottom plate; the fan is fixed on a side surface in the casing and opposite to the side surfaces of coils in the coil component in the casing; ventilation air generated after the fan rotates can cool the coils in the coil component at the same time, so as to avoid the defect that only one coil can be cooled in the prior art; and a vent hole on the casing improves ventilation of the air with the outside, so that the normal working temperature of the coils is effectively ensured. The utility model has the advantages of smooth ventilation, obvious cooling effect, high cooling efficacy of the fan, and long service life of the transformer.
Description
Technical field
The utility model relates to a kind of transformer, particularly a kind of transformer of industrial use.
Background technology
Transformer is to utilize electromagnetic induction principle, transmit the instrument of electric energy to another circuit from a circuit, mainly comprise a primary coil and a secondary coil in the transformer, the skeleton of coil forms with hot rolling or the cold-reduced silicon sheet closed assembly that the surface scribbles insulating varnish, the thickness of silicon steel sheet is 0.35mm or 0.5mm, silicon steel sheet behind the closed assembly is the magnetic circuit part in the transformer, be wound with flat or circular enamelled wire on the silicon steel sheet, enamelled wire has been formed the circuit part in the transformer, under the effect of common flux, because the enamelled wire number of turn is different on primary coil and the secondary coil, make under the effect of electromagnetic induction principle, the voltage of secondary coil output changes, and reaches the purpose of voltage transitions.Because primary coil and secondary coil can produce a large amount of heats at work, existing situation all is to adopt fan to carry out the Direct Air-Cooled cooling, because fan is fixed on the back plate in the transformer, air directly can only lowered the temperature to primary coil in the convection process, then can not play effective cooling effect to secondary coil, make in the transformer course of work coil environment temperature higher, the operating efficiency and the useful life of transformer have been influenced, increased energy resource consumption, how to avoid this situation to take place, the operating efficiency of improving transformer is the problem that the utility model need solve.
Summary of the invention
In view of above-mentioned deficiency of the prior art, the utility model aims to provide and a kind ofly can effectively reduce the coils in transformers working temperature, improves the coil working efficient and the transformer in useful life.
The utility model is achieved through the following technical solutions:
A kind of transformer, comprise housing, fan, base plate, coil block and the actuation means that is connected with coil block, base plate is positioned at housing, and coil block is connected on the base plate, fan is fixed on the side in the housing, and fan is relative with the side of coil in the housing interior loop assembly.
The position that described housing is corresponding with fan is provided with air vent hole.
The described number of fans that is fixed in the housing is more than one.
A kind of transformer described in the utility model, utilize the supporting role of housing, fan is installed on the position relative with coil in the coil block, side in the housing, the ventilating air that fan rotation back is produced can be lowered the temperature to the coil in the coil block simultaneously, having avoided before can only be to the shortcoming of a coil cooling, air vent hole on the housing has improved air and extraneous circulation, effectively guaranteed the normal working temperature of coil, have that circulation of air is smooth and easy, cooling-down effect obviously, the advantage of fan for cooling effect height, transformer long service life.
Description of drawings
Fig. 1 is a structural representation sketch of the present utility model.
Embodiment
Be further described below in conjunction with 1 pair of the utility model of accompanying drawing:
A kind of transformer described in the utility model comprises housing 4, fan 2, base plate 5, coil block 3 and the actuation means 6 that is connected with coil block 3.Wherein, base plate 5 is positioned at housing 4, coil block 3 is connected on the base plate 5, include a primary coil 3a and a secondary coil 3b in the coil block 3, the quantity of fan 2 is one, fan 2 is fixed on the side in the housing 4, and fan 2 is relative with the side of two coils in the housing 4 interior loop assemblies 3.Position corresponding with fan 2 on the housing 4 has air vent hole 1, and the direction that air vent hole 1 can make things convenient for air to blow out along fan 2 is by convection into outside the housing 4.Certainly, the quantity that is fixed on the fan 2 of housing 4 sides also can be more than one, and its quantity can be decided according to the needs that reality is used, but each fan 2 all can be finished simultaneously the coil in the coil block 3 is carried out cooling effect.
In the actual use, because fan 2 is positioned at the side of primary coil 3a and secondary coil 3b, can lower the temperature to two coils simultaneously after fan 2 rotations, air vent hole 1 on the housing 4 has guaranteed the circulation between the air and the external world, two coils cooling needs have at work been realized, the situation of having avoided fan 2 before to lower the temperature to a coil.
Claims (3)
1, a kind of transformer, comprise housing, fan, base plate, coil block and the actuation means that is connected with coil block, described base plate is positioned at housing, coil block is connected on the base plate, it is characterized in that, described fan is fixed on the side in the housing, and fan is relative with the side of coil in the housing interior loop assembly.
2, a kind of transformer according to claim 1 is characterized in that, the position that described housing is corresponding with fan is provided with air vent hole.
