The technical scheme is that the self-shielding leakage flux anti-overheating iron core comprises iron core laminations (1), a first heat dissipation oil passage (2), a second heat dissipation oil passage (3) and a pull plate (4), wherein the iron core laminations (1) comprise a last stage iron core lamination (5) and a penultimate stage iron core lamination (6), the pull plate (4) is arranged above the last stage iron core lamination (5), the second heat dissipation oil passage (3) is arranged between the last stage iron core lamination (5) and the pull plate (4), the first heat dissipation oil passage (2) is arranged between the last stage iron core lamination (5) and the penultimate stage iron core lamination (6), the last stage iron core lamination (5) of the iron core laminations (1) is of a directly spliced structure, and other laminations of the iron core laminations (1) are of inclined seam and stepping lap-joint structures. The self-shielding leakage flux anti-overheating iron core has the advantages that heating of the iron core structural parts and local overheating of the iron core laminations are avoided, and transformer loss is reduced.
Description
Technical field
The present invention relates to the anti-Superheating of a kind of self-shileding leakage flux unshakable in one's determination, especially Large Copacity, high-tension generator transformer core construction, belong to transformer manufacture technology field.
Background technology
Large Copacity, high-tension generator transformer, because its capacity is comparatively large, leakage flux total amount is also large, cause iron core, fuel tank serious by leakage field impact, local overheating problem is comparatively serious, and the existence of low-voltage, high-current lead-in wire, more exacerbate fuel tank and local overheating situation unshakable in one's determination.If adopt web unshakable in one's determination, arm-tie syndeton, then can form loop wherein and cause circulation, it is overheated that link position very easily occurs.Equally, if to taking insulation system therebetween, then leakage field enters core lamination, because core lamination is similarly electric conductor, in lamination, produce circulation, and the seaming position resistance of lamination is large, and easily produce virtual connection, therefore, the seaming position of lamination also very easily produces local overheating.
Summary of the invention
It is unshakable in one's determination that the object of the invention is to provide the anti-Superheating of a kind of self-shileding leakage flux, between final stage lamination unshakable in one's determination and iron core time final stage lamination, heat radiation oil duct is set, utilize the high magnetic resistance of oil clearance, leakage field is completely cut off in final stage core lamination, solve Problems existing in background technology.
Technical scheme of the present invention is:
The anti-Superheating of a kind of self-shileding leakage flux is unshakable in one's determination, comprise core lamination, heat radiation oil duct one, heat radiation oil duct two and arm-tie, described core lamination comprises final stage lamination unshakable in one's determination and iron core time final stage lamination, arm-tie is provided with above final stage lamination unshakable in one's determination, heat radiation oil duct two is provided with between final stage lamination unshakable in one's determination and arm-tie, heat radiation oil duct one is provided with between final stage lamination unshakable in one's determination and iron core time final stage lamination, final stage lamination unshakable in one's determination in core lamination is direct splicing structure, and other lamination in core lamination is mitre step lapped structure.
Final stage lamination both sides unshakable in one's determination in described core lamination are respectively equipped with heat radiation oil duct three.
The invention has the beneficial effects as follows: avoid core construction part to generate heat and core lamination local overheating, reduce transformer loss.

Embodiment
Below in conjunction with accompanying drawing, by example, the invention will be further described.
With reference to accompanying drawing 1, the anti-Superheating of a kind of self-shileding leakage flux is unshakable in one's determination, comprise core lamination 1, heat radiation oil duct 1, heat radiation oil duct 23 and arm-tie 4, described core lamination 1 comprises final stage lamination 5 unshakable in one's determination and iron core time final stage lamination 6, arm-tie 4 is provided with above final stage lamination 5 unshakable in one's determination, heat radiation oil duct 23 is provided with between final stage lamination 5 unshakable in one's determination and arm-tie 4, heat radiation oil duct 1 is provided with between final stage lamination 5 unshakable in one's determination and iron core time final stage lamination 6, final stage lamination unshakable in one's determination 5 in core lamination 1 is direct splicing structure, and other lamination in core lamination 1 is mitre step lapped structure.
In the present embodiment, final stage lamination 5 both sides unshakable in one's determination in core lamination 1 are respectively equipped with heat radiation oil duct three, to strengthen the heat radiation to final stage lamination 5 unshakable in one's determination.Described core lamination adopts silicon steel sheet material, utilizes the high magnetic resistance of the high permeance of silicon steel sheet and oil clearance, is completely cut off by leakage field in final stage iron core, does not allow it enter unshakable in one's determination inner.
With reference to accompanying drawing 3,4, the direct splicing structure of core lamination and mitre step lapped structure are the common connecting method of core lamination, final stage lamination 5 unshakable in one's determination adopts direct splicing structure (accompanying drawing 3), when final stage lamination unshakable in one's determination is operationally constantly shaken, the sheet Contact of the guarantee seam crossing of high degree, prevent the generation of virtual connection, the local overheating phenomenon of anti-position here occurs.To other core lamination except final stage lamination unshakable in one's determination, adopt mitre, stepping overlapping mode (accompanying drawing 4), greatly contain the overheated effectiveness of leakage field in core construction part and core lamination.
