Description
Technical field
The utility model relates to field transformer, particularly relates to a kind of transformer with cooling device.
Background technology
Transformer is a kind of converting electric power and static electromagnetic device electric energy being delivered to another circuit from a circuit.EI transformer is a kind of in electronic transformer, and its iron core is by " E " matrix and " " matrix stacks up I, is referred to as EI transformer according to its shape.EI transformer generally uses as power frequency (low frequency) transformer, power transformer and audio frequency transformer.
For powerful EI transformer, when serious problem of generating heat often appears in its full operationally iron core, the heat-sinking capability of transformer self is only relied on often to be difficult to the radiating effect reaching hope.In addition, existing EI transformer can only realize general impedance, cannot realize high impedance, and more the shell of part EI transformer has and adopt plastics or ceramic material, easily damaged because of collision, and then may threaten the safety of user.
Utility model content
The purpose of this utility model proposes a kind of transformer with cooling device, can avoid transformer in running, occur the problem of fully loaded overtemperature.
For achieving the above object, the utility model provides a kind of transformer with cooling device, comprise insulation shell, day font iron core, insulated coil skeleton and the coil of winding on described insulated coil skeleton, described day font iron core, insulated coil skeleton and coil be all arranged in described insulation shell, is provided with coolant in described insulation shell; Also comprise external cooling device, described external cooling device is connected with described insulation shell by circulation line, is circulated carry out cooling down by coolant between described insulation shell and external cooling device.
Further, described coolant is cold oil or water.
Further, described external cooling device is Air cooler or water cooling unit.
Further, crashproof layer is respectively equipped with in the upper and lower surface of described insulation shell.
Further, described crashproof layer adopts fiber.
Further, described day font iron core is provided with at least one leakage field space iron core, and described leakage field space iron core is made up of permeability magnetic material and gap backing plate, and is positioned at the centre position of described day font iron core.
Further, described day font iron core be formed by stacking by E type silicon steel sheet and I type silicon steel sheet, and the middle part extension of described E type silicon steel sheet is described leakage field space iron core.
Based on technique scheme, the utility model by being connected to external cooling device by circulation line outside insulation shell, the heat that transformer core is distributed can being recycled in air by coolant, thus avoid Yin Wendu too high and cause danger.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, and form a application's part, schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the utility model with an embodiment of the transformer of cooling device.
Fig. 2 is the structural representation of the utility model with the Sino-Japan font iron core of transformer embodiments of cooling device.
Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
See Fig. 1,2, the transformer of the present embodiment comprise insulation shell 1, day font iron core 2, insulated coil skeleton 3 and the coil 4 of winding on insulated coil skeleton 3, iron core 2, insulated coil skeleton 3 and coil 4 are all arranged in insulation shell 1, are provided with coolant in insulation shell 1.Transformer also comprises external cooling device 8, and this external cooling device is connected with insulation shell 1 by circulation line, is circulated carry out cooling down by coolant between insulation shell 1 and external cooling device 8.Owing to being connected to external cooling device by circulation line outside insulation shell, the heat that transformer core is distributed can being recycled in air by coolant, thus avoid Yin Wendu too high and cause danger.
Preferably, can arrange crashproof layer 6 respectively in the upper and lower surface of insulation shell, this crashproof layer 6 can avoid EI type transformer impaired because of collision, improves use safety.Crashproof layer 6 preferably adopts fiber.
As shown in Figure 2, day font iron core 2 can also be provided with at least one leakage field space iron core 7.Leakage field space iron core 7 is made up of permeability magnetic material 72 and gap backing plate 71, is positioned at a day centre position for font iron core 2.And day font iron core 2 to be formed by stacking by E type silicon steel sheet 21 and I type silicon steel sheet 22, and the middle part extension of E type silicon steel sheet 21 is leakage field space iron core 7.Owing to being provided with at least one leakage field space iron core in the leakage field space of EI type transformer, leakage flux can be made to be significantly improved, and then improve transformer impedance, greatly reduce the stray loss of transformer, reduce the adverse effect of leakage field simultaneously.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to embodiment of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
