As the visual plant of electrical system, transformer is widely applied to every field.Dry-type transformer is a kind of as transformer, and with respect to oily formula transformer, it does not have fire, blast and pollution problems, so dry-type transformer is widely used in every field such as industry, electric power.
The safe operation of dry-type transformer and useful life, depend on the safe and reliable of Transformer Winding insulation to a great extent.Winding temperature surpasses the insulation tolerable temperature makes insulation breakdown, is the one of the main reasons that causes the transformer cisco unity malfunction.Usually, the type of cooling of dry-type transformer is divided into natural cooling and blower fan cooling.Start blower fan when the dry-type transformer natural cooling can not reach when cooling requires, make the temperature rise control of dry-type transformer meet class of insulation requirement.
As shown in Figure 1, the blower fan 4 of existing dry-type transformer is installed in the bottom of this transformer usually, adopts the mode of top-blown or side blown type to dry to the air channel.Simultaneously, as shown in Figure 2, blower fan 4 directly is fixedly mounted on the band steel of dry-type transformer iron core folder.Because fixedly the folder main body 1 of the iron core folder of blower fan is closed, as shown in Figure 3 fully, when dry-type transformer is worked, in the iron core folder, will form the closed magnetic line of force 5.Because conductor moves in non-uniform magnetic-field or when being in the mM disodium hydrogen phosphate, the electric current that the conductor internal induction produces can cause energy loss, this loss is called eddy current loss.In existing dry-type transformer; Owing to can produce closed magnetic circuit in the iron core folder of transformer; When iron core 6 places such mM disodium hydrogen phosphate, time dependent magnetic flux is wherein just arranged, the secondary of iron core 6 will produce induced electromotive force; In iron core 6, also produce simultaneously induced electromotive force, thereby produce eddy current.These eddy current make iron core 6 heatings, consume unnecessary electric energy, and this loss is undesirable.
The utility model content
The purpose of the utility model provides a kind of iron core folder of transformer, and when transformer was worked, this iron core folder inside can not produce the closed magnetic line of force, avoids iron core to produce unnecessary heat, thereby saves electric energy.
The utility model also provides a kind of cooling device that comprises this iron core folder.
In addition, the utility model also provides a kind of transformer that comprises this cooling device.
To achieve these goals, the iron core folder of the transformer that the utility model provides comprises the folder main body, and the cross section of said folder main body is non-close-shaped.
Preferably, the cross section of said folder main body is the rectangle that breaks off on one side.
Preferably, said iron core folder also comprises the insulator that is fixed on the said folder main body.
Preferably, said insulator is fixed on the non-closing section of cross section of said folder main body.
The cooling device of the transformer that the utility model provides comprises blower fan and said iron core folder, and said blower fan is fixed on the iron core folder of said transformer.
Preferably, said blower fan is fixed on the non-closing section of said cross section of said iron core folder.
Preferably, said blower fan is fixed on the said insulator.
The transformer that the utility model provides comprises said cooling device.
Through technique scheme, the iron core folder of the transformer that employing the utility model provides is because the cross section of the folder main body of iron core folder is non-close-shaped; Therefore; During transformer work, can not produce closed magnetic circuit in the said iron core folder, the iron core of transformer just can not produce eddy current; Thereby avoid producing unnecessary heat, saves energy.
Other feature and advantage of the utility model will partly specify in embodiment subsequently.

Embodiment
Be elaborated below in conjunction with the embodiment of accompanying drawing to the utility model.Should be understood that embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
Iron core folder according to the transformer of the utility model comprises folder main body 1, and wherein, the cross section of folder main body 1 is the shape of non-closure.
Because the cross section of the folder main body 1 of iron core folder is non-close-shaped, therefore, during transformer work, can not produce closed magnetic circuit in the said iron core folder, the iron core 6 of transformer just can not produce eddy current, thereby avoids producing unnecessary heat, saves energy.
The cross section of folder main body 1 can be the shape of any non-closure, as long as guarantee the non-closed of iron core folder.For convenience of processing the iron core folder and the convenience that blower fan is installed, preferably, the cross section of folder main body 1 is the rectangle that breaks off on one side.
Preferably, said iron core folder also comprises the insulator 2 that is fixed on the folder main body 1.Insulator 2 can be installed in any position of folder main body 1, and certainly, for the fixing convenience of blower fan 4, preferably, insulator 2 is fixedly mounted on the non-closing section 3 of cross section of folder main body 1.The mounting means of insulator 2 can adopt existing any fixed form, for easy for installation, adopts bolt 7 fixed installation insulators 2.
