Description
Technical field
The utility model relates to transformer technology field, particularly one large-scale high voltage transformer final stage core lamination structure.
Background technology
Manufacturing in large-scale and super-huge power transformer process, due to the eddy current loss that horizontal leakage flux produces in iron core, usually need the final stage (outermost level) of iron core to make slot treatment.When making slot treatment, what the most generally adopt now is utilize shearing equipment directly to go out elongated slot on lamination.The shortcoming of this mode is: (1) lamination fluting quantity and width limit by equipment, arbitrarily can not change according to the actual demand of transformer; (2) middle column sheet of existing high-power transformer is fish tail sheet shape, and upper and lower yoke adopts the structure of notched shape, thus can produce a large amount of not available waste material of silicon sheet in snip process; (3) first punching during the groove milling mould fluting utilizing lamination shearing equipment to carry, then milling groove between Kong Yukong, consuming time and the burr of lamination can be strengthened; (4) not that every platform lamination shearing equipment has this function of fluting.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of large-scale high voltage transformer final stage core lamination structure, and this core lamination structure is slotted without using shearing equipment, and can not produce waste material, save time, structural design is flexible.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions: a kind of large-scale high voltage transformer final stage core lamination structure, comprise center pillar stack of laminations, upper yoke lamination, lower yoke lamination, left side post lamination and the right post lamination, described center pillar stack of laminations comprises three center pillar laminations, each center pillar lamination is combined into by multiple rectangle lamination, and in multiple rectangle laminations of each center pillar lamination, slot is formed between two adjacent rectangle laminations, insulating board can be inserted in this slot, described three center pillar laminations vertically arrange, the upper end of these three center pillar laminations is vertically spliced with described upper yoke lamination respectively, the lower end of three center pillar laminations is vertically spliced with described lower yoke lamination respectively, between the left end of described upper yoke lamination and the upper end of described left side post lamination, between the right-hand member of upper yoke lamination and the upper end of described the right post lamination, between the left end of lower yoke lamination and the lower end of described left side post lamination and be 45 degree between the right-hand member of lower yoke lamination and the lower end of described the right post lamination and tiltedly spell.
Further, described each center pillar lamination is combined into by three rectangle laminations.
Further, described upper yoke lamination and lower yoke lamination are combined into by multiple iron yoke burst respectively.
The beneficial effects of the utility model are: the center pillar lamination in the utility model is combined into by multiple rectangle lamination, and in multiple rectangle laminations of each center pillar lamination, form slot between two adjacent rectangle laminations, in this slot, insert insulating board.The utility model risks slot by multiple rectangle iron plate, quantity and the width of slot do not limit, solve core lamination final stage fluting problem, slot without using shearing equipment, thus also can not produce waste material, also save notching time when core lamination is sheared, thus compare and save time, total simplicity of design is flexible simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.
As shown in Figure 1, a kind of large-scale high voltage transformer final stage core lamination structure, comprise center pillar stack of laminations, upper yoke lamination 1, lower yoke lamination 2, left side post lamination 3 and the right post lamination 4, described center pillar stack of laminations comprises three center pillar laminations 5, each center pillar lamination 5 is combined into by multiple rectangle lamination 51, and in multiple rectangle laminations 51 of each center pillar lamination 5, slot 6 is formed between two adjacent rectangle laminations 51, insulating board is inserted in this slot 6, described three center pillar laminations 5 vertically arrange, the upper end of these three center pillar laminations 5 is vertically spliced with described upper yoke lamination 1 respectively, the lower end of three center pillar laminations 5 is vertically spliced with described lower yoke lamination 2 respectively, between the left end of described upper yoke lamination 1 and the upper end of described left side post lamination 3, between the right-hand member of upper yoke lamination 1 and the upper end of described the right post lamination 4, between the left end of lower yoke lamination 2 and the lower end of described left side post lamination 3 and be 45 degree between the right-hand member of lower yoke lamination 2 and the lower end of described the right post lamination 4 and tiltedly spell.
Furtherly, described each center pillar lamination 5 is combined into by three rectangle laminations 51.
Furtherly, described upper yoke lamination 1 and lower yoke lamination 2 are combined into by multiple iron yoke burst respectively.
