Described iron core is divided into upper and lower two parts; Described coil is placed on described iron core the latter half; Upper and lower two parts seam of described iron core connects.
Further, also comprise mercurial thermometer, temperature meter base and oil level indicator, for showing the oil level indicator of oil level and the temperature meter base for laying thermometer is all placed in described case lid, described mercurial thermometer is inserted in described temperature meter base.
Further, also comprise nameplate, described nameplate is placed in upper position in the middle of described radiator.
Further, described casing to be cross section be staving that chamfering 60 ° arranges in hexagon, described hexagon has 3 long limits and 3 minor faces, described radiator be placed in described casing be place, hexagon long limit lateral wall on.
Further, each iron core frame forms by organizing longitudinal ladder n level core lamination stack seam more, and have predetermined interval distance between seam core lamination stack at different levels, the cross section of described each iron core frame is the rectangular configuration of chamfering 8*45 °; Wherein, the seaming position of core lamination stack is the upper and lower two-part split position of each iron core frame.
Further, described insulating barrier is epoxy plate.
Further, described iron core is coated with insulating varnish on the surface,
Compared with prior art, the present invention at least has the following advantages:
By the design of voltage device of the present invention, improve production efficiency, shorten the production cycle, reduce loss and cost, enhance anti-short circuit capability and overload capacity, and technique simply, is easily repaired.

Embodiment
Below in conjunction with accompanying drawing, specific embodiments of the present invention is described in detail.
With reference to Fig. 1 ~ 4, the double joint folding stereo triangle oil-filled transformer of the present embodiment, comprising casing 1, case lid 2, radiator 3, oil level indicator 4, temperature meter base 5, iron core 6, iron core folder 7, transformer oil 8, nameplate 9, insulating barrier 10, strap 11, mercurial thermometer 12 and coil, case lid 2 being provided with the display oil level indicator 4 of oil level and the temperature meter base 5 for laying thermometer; Wherein, oil level indicator 4 is embedded in case lid 2, temperature meter base 5 is fixed on case lid 2, mercurial thermometer 12 inserts in temperature meter base 5, casing 1 and case lid 2 form the cavity volume for holding iron core, and iron core 6, iron core folder 7 and coil are immersed in the cavity volume of injection transformer oil 8, and casing 1 is the staving that hexagon is arranged for cross section is chamfering 60 °, this hexagon has 3 long limits and 3 minor faces, radiator 3 be placed in casing 1 be place, hexagon long limit lateral wall on; Nameplate 9 is placed in the middle upper position of radiator 3.
Iron core 6 is put together between two by three identical iron core frames, and in isosceles triangle, arrangement is erected on iron core folder 7; Each iron core frame mosaic insulating barrier 10 separates; Wherein, insulating barrier 10 is epoxy plate, and iron core 6 is coated with insulating varnish on the surface.
Each iron core frame forms by organizing longitudinal ladder n level core lamination stack seam more, and have predetermined interval distance between seam core lamination stack at different levels, the cross section of each iron core frame is the rectangular configuration of chamfering 8*45 °.Wherein, each core lamination stack stacked arrangement on iron core frame.Concrete, n can be 5, and each iron core frame forms by organizing longitudinal ladder 5 grades of core lamination stack seams more, and every 1 core lamination stack is 1 grade, stepping 10mm between seam core lamination stack at different levels; Or change according to actual conditions, n can be 7, and each iron core frame forms by organizing longitudinal ladder 7 grades of core lamination stack seams more, and every 2 core lamination stacks are 1 grade, stepping 7mm between seam core lamination stack at different levels.
Iron core 6 strap 11 tightens up; Iron core 6 is split into upper and lower two parts, and the first half is connected with the latter half seam; Concrete, the independent coiling of coil, is inserted in iron core the latter half after coiling completes, then iron core the first half is inserted iron core the latter half.
By the design of the invention described above technical scheme, make coil can coiling separately, use traditional coil winding machine just passable, do not need to introduce new spooling equipment again, decrease up-front investment from another point of view, decrease the wasting of resources, and its wire winding is also much simple than closed type, coiling difficulty is low;
Meanwhile, production efficiency significantly improves.And due to iron core be opening, be inserted in iron core after traditional coil winding machine can be used to be completed by coil winding, so can increase other spooling equipments, two carry out its coil can separate with iron core and make, and shortens the production cycle, and easy to maintenance.
The difficulty of producing jumbo transformer is low, owing to not needing mould and iron core wrapping machine, can large-scale popularization in the transformer of Large Copacity, voltage levels.
Do not need annealing, just receive very little shearing force in process of production because it is unshakable in one's determination, so do not need annealing, eliminate the destruction to environment in annealing process, protect environment.
Low according to market situation adjusted design scheme cost, when needs change, because it along with the variation of prices of raw and semifnished materials adjusted design at any time, can highlight his compliance and flexibility, reached the needs in product adaptation market.
Wherein, the modules of apparatus of the present invention can be integrated in one, and also can be separated deployment.Above-mentioned module can merge into a module, also can split into multiple submodule further.
