Description
Technical field
The present invention relates to transformer technology fields, and in particular to a kind of insulation board of electrical transformer cores.
Background technique
Transformer is the power equipment for changing alternating voltage using the principle of electromagnetic induction, can play electricity in circuit
The effects of buckling changes, current transformation, impedance transformation, pressure stabilizing has wide in many fields such as power supply, machine-building, metallurgy, railway
General application.Iron core is the important component in transformer, is mainly made of iron core and coil, during the work time, iron core meeting
Loss is generated so that part electric energy is changed into thermal energy, causes the waste of power supply, the loss of energy can also be such that the temperature of iron core rises,
If iron core works at high temperature for a long time, aging can occur for the insulating layer on its surface, further increase loss.In recent years,
Countries in the world face the energy crisis got worse, it is desirable that power equipment includes that transformer will further decrease loss, improve energy
Source utilization rate, the energy conservation of transformer whether are an important indicators for examining transformer quality, general energy conservation, low-coumption transformation
Device includes power supply energy loss and raw material loss objective in energy-saving index；
Just need to solve structure design, the insulation of iron core of manufacture transformer core in conclusion to solve the above problems
The integrity problem of hardened structure and iron core in use, this patent have carried out corresponding improvement for the insulation board of iron core；
During the installation of the insulation board of iron core, especially for the insulation between upper yoke column or lower yoke column and center pillar
Plate, the insulation board at this are all the peripheries for being set in center pillar, then again by the insulation board of center pillar periphery to it when installation
It is fixed, will make gap occur between insulation board and upper yoke column or lower yoke column at upper yoke column or lower yoke column at this time, it should
The heat at place just needs to radiate by air flowing, moreover, because at this and other places are by upper yoke column or lower yoke column
Insulation board isolation, so the heat flow coefficient at this is different from flow coefficient elsewhere, has led to transformer at this time
Local temperature it is excessively high；Moreover, the insulation board at upper yoke column or lower yoke column is all used only to insulate, and there is no empty well
Flow of air guiding role, and then affect the efficiency of transformer core heat dissipation.
Summary of the invention
The present invention is above-mentioned in order to overcome the shortcomings of, provides a kind of insulation board of electrical transformer cores.
The present invention through the following technical solutions to achieve the above objectives:
A kind of insulation board of electrical transformer cores, including insulation board ontology, the shape of insulation board ontology are circular ring shape, absolutely
The thickness of listrium ontology is gradually reduced along the direction of outer circle circumference of the center of circle to the circular ring shape of circular ring shape, insulation board ontology it is upper
End face is level；
Spacing are equipped with several fixture blocks on the inner circle edge of the insulation board ontology etc., and the center line of fixture block is by circular ring shape
The center of circle, fixture block are equipped with groove close to the side in the center of circle, and the center of circle corresponding to groove is formed close to the center of circle of circular ring shape, each fixture block
The radius of inner circle is less than the inner circle radius of circular ring shape；
A diversion trench, the fan-shaped distribution of diversion trench are equipped between two adjacent fixture blocks.
It is for the insulation board at upper yoke column or lower yoke column in the insulation board of the electrical transformer cores；
The insulation board ontology is covered in the insulation board periphery of electrical transformer cores center pillar first, is subsequently moved to electric power change
The end of the insulation board of depressor iron core middle column, then by each fixture block of insulation board ontology inner circle in electrical transformer cores
The insulation board of column is clamped, then allows for the end that insulation board ontology is fixed on the insulation board of electrical transformer cores center pillar
Portion, meanwhile, upper surface and the upper yoke of insulation board ontology fit closely, and heat can be transmitted effectively, entire transformation is realized
The case where heat of device forms an entirety, is not in hot-spot；
Wherein, the groove of fixture block end can be fitted in the insulation board at center pillar, significantly more efficient to be fitted at center pillar
Insulation board；
Meanwhile the diversion trench being equipped between two adjacent fixture blocks, and the fan-shaped distribution of diversion trench can will be at center pillar
Heat be effectively oriented to the periphery of transformer, simultaneously because the thickness of insulation board ontology is along the center of circle of circular ring shape to circular ring shape
The direction of outer circle circumference is gradually reduced, then has been more in line with the mechanism of hot-air flowing, has effectively increased at the heat of transformer
Manage efficiency.
Preferably, the angle between two adjacent fixture blocks is 45 degree；It, can when the quantity of fixture block is 8
Effectively the insulation board of electrical transformer cores center pillar is clamped.
Preferably, angle radian is at 30~40 degree corresponding to the sector of the diversion trench.
Preferably, the notch of the groove has at a distance from 1~2cm between the side of fixture block；Prevent groove both ends with
The spine formed between fixture block scratches the insulation board of electrical transformer cores center pillar.
Preferably, the insulation board ontology is made of phenolic resin.
The beneficial effects of the present invention are: in the insulation board of the electrical transformer cores, it is effectively fixed in by each fixture block
Insulation board at column；Moreover, realizing effective quick processing to heat plus the diversion trench at insulation board ontology, electricity is improved
The radiating efficiency of power transformer core.
