Description
Technical field
The utility model relates to field transformer, particularly relates to a kind of transformer 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.For powerful transformer, when its full-load run often there is serious problem of generating heat in iron core, overheated, the normal use of transformer can be had a strong impact on, even may cause danger, only rely on the heat-sinking capability of transformer self to be often difficult to the radiating effect reaching hope.
Utility model content
The purpose of this utility model proposes a kind of transformer cooling device, fully can cool transformer, meets its instructions for use when full-load run.
For achieving the above object, the utility model provides a kind of transformer cooling device, for the cooling of transformer, described transformer comprises transformer body and insulation crust, coolant is provided with in described insulation crust, described transformer cooling device is included in the first cooler of the interior setting of shell wall of described insulation crust and is arranged on outside described insulation crust, and the second cooler of coolant described in circulating cooling is carried out by circulation line and compression pump, selectively use described first cooler and/or the second cooler to cool described transformer body.
Further, described first cooler is through ducts, the multiple front and back be arranged in the shell wall of described insulation crust.
Further, the cross section in described duct is rectangle, rhombus, circle or oval.
Further, loop exit and the loop head of described coolant is provided with in described insulation crust, described loop exit is communicated with described second cooler respectively by circulation line with loop head, and described compression pump is located between described loop exit and described second cooler.
Further, be positioned at the top of described insulation crust at described loop head, be provided with the injector head for spraying described coolant above the inner chamber of described insulation crust, described injector head is communicated with described loop head, and has multiple nozzle.
Further, described second cooler is air cooler or water cooler.
Based on technique scheme, the utility model have employed two kinds of multi-form coolers and cools transformer, select one or two corresponding transformer to use according to actual needs, thus realize fully cooling transformer, meet its instructions for use when full-load run.
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 an embodiment of the utility model transformer cooling device.
Fig. 2 is the structural representation of another embodiment of the utility model transformer cooling device.
Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, be the structural representation of an embodiment of the utility model transformer cooling device.In the present embodiment, transformer cooling device is used for the cooling of transformer, and transformer comprises transformer body 2 and insulation crust 1, coolant is provided with in insulation crust 1, transformer cooling device is included in the first cooler of the interior setting of shell wall of insulation crust 1 and is arranged on outside insulation crust 1, and the second cooler 4 of this coolant of circulating cooling is carried out by circulation line and compression pump 3, selectively can use the first cooler or the second cooler 4 according to actual needs, or use the first cooler and the second cooler to cool transformer body 2 simultaneously, thus realize fully cooling transformer, meet its instructions for use when full-load run.In addition, in order to ensure insulation crust 1 not cracky, lower surface can also arrange the crashproof layer 6 of resin fibre material thereon.
In FIG, the first cooler is through rectangle ducts 7, the multiple front and back be arranged in the shell wall of insulation crust 1.The flowing of air in rectangle duct 7 is utilized to be delivered to heat on insulation crust to carry away transformer body 2 in use.
Loop exit and the loop head of coolant is provided with in insulation crust 1, and loop exit and loop head are communicated with the second cooler 4 respectively by circulation line, compression pump 3 is located between loop exit and the second cooler 4, by compression pump, the coolant in insulation crust 1 is circulated to return interior mode from inside to outside.Preferably, can arrange loop head on the top of insulation crust 1, and above the inner chamber of insulation crust, arrange the injector head 5 for spraying coolant, injector head 5 is communicated with loop head, and has multiple nozzle.This makes it possible to make cooled coolant looping back in insulation crust 1 and can cool transformer body 2 in the mode of spray, thus to realize more fully cooling effect, avoid local overheating.
Second cooler can select air cooler or water cooler, also can adopt other existing cooling systems.
As shown in Figure 2, be the structural representation of another embodiment of the utility model transformer cooling device.Compared with a upper embodiment, first cooler of the present embodiment is through oval ducts 7 ', the multiple front and back be arranged in the shell wall of insulation crust 1.In other embodiments, the cross section in duct, except rectangle and ellipse, can also adopt rhombus or cross section, duct that is circular and irregular shape.
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.
