Description
Technical field
The present invention relates to the generator changes of a kind of anti-Superheating iron core of self-shileding leakage magnetic flux, especially large capacity, high voltage
Depressor core construction belongs to transformer manufacture technology field.
Background technology
The generator transformer of large capacity, high voltage, since its capacity is larger, leakage magnetic flux total amount is also big, causes iron core, oil
Case is influenced serious by leakage field, and hot-spot problem is more serious, and the presence of low-voltage, high-current lead, more exacerbate fuel tank and
The hot-spot situation of iron core.If using iron core web, pulling plate connection structure, loop can be formed wherein and cause ring
Stream, link position easily overheat.Equally, if to taking insulation system therebetween, leakage field enters core-lamination stack, due to iron
Heart lamination is similarly electric conductor, and circulation is generated in lamination, and the seaming position resistance of lamination is big, and easily generates virtual connection,
Therefore, the seaming position of lamination also easily generates hot-spot.
The content of the invention
It is penultimate in iron core final stage lamination and iron core it is an object of the present invention to provide a kind of anti-Superheating iron core of self-shileding leakage magnetic flux
Heat radiation oil duct is set between grade lamination, using the high magnetic resistance of oil clearance, by leakage field isolation in final stage core-lamination stack, solves background skill
Problem present in art.
The technical scheme is that：
A kind of anti-Superheating iron core of self-shileding leakage magnetic flux comprising core-lamination stack, heat radiation oil duct one, heat radiation oil duct two and is drawn
Plate, the core-lamination stack include iron core final stage lamination and iron core penult lamination, pulling plate, iron core are equipped with above iron core final stage lamination
Heat radiation oil duct two is equipped between final stage lamination and pulling plate, heat radiation oil duct is equipped between iron core final stage lamination and iron core penult lamination
One, the iron core final stage lamination in core-lamination stack is direct splicing structure, and other laminations in core-lamination stack are taken for mitre stepping
Connect formula structure.
Iron core final stage lamination both sides in the core-lamination stack are respectively equipped with heat radiation oil duct three.
The beneficial effects of the invention are as follows：The fever of core construction part and core-lamination stack hot-spot are avoided, reduces transformer damage
Consumption.

Specific embodiment
Below in conjunction with attached drawing, by example, the invention will be further described.
Referring to the drawings 1, a kind of anti-Superheating iron core of self-shileding leakage magnetic flux includes core-lamination stack 1, heat radiation oil duct 1, heat dissipation
Oil duct 23 and pulling plate 4, the core-lamination stack 1 include iron core final stage lamination 5 and iron core penult lamination 6, iron core final stage lamination 5
Top is equipped with pulling plate 4, and heat radiation oil duct 23 is equipped between iron core final stage lamination 5 and pulling plate 4, and iron core final stage lamination 5 is penultimate with iron core
Heat radiation oil duct 1 is equipped between grade lamination 6, the iron core final stage lamination 5 in core-lamination stack 1 is direct splicing structure, core-lamination stack 1
In other laminations be mitre step lapped structure.
In the present embodiment, 5 both sides of iron core final stage lamination in core-lamination stack 1 are respectively equipped with heat radiation oil duct three, to strengthen
Heat dissipation to iron core final stage lamination 5.The core-lamination stack uses silicon steel sheet material, utilizes high permeance and the oil of silicon steel sheet
The high magnetic resistance of gap by leakage field isolation in final stage iron core, does not allow it to enter inside iron core.
Referring to the drawings 3,4, the direct splicing structure and mitre step lapped structure of core-lamination stack are normal for core-lamination stack
The connecting method seen, iron core final stage lamination 5 use direct splicing structure（Attached drawing 3）So that iron core final stage lamination is operationally not
It in the case of disconnected vibrations, is contacted between the piece of the guarantee seam crossing of high degree, prevents the generation of virtual connection, prevent the part of position here
Superheating phenomenon occurs.To other core-lamination stacks in addition to iron core final stage lamination, using mitre, stepping overlapping mode（Attached drawing
4）, greatly contain overheat effectiveness of the leakage field in core construction part and core-lamination stack.
