Abstract
The utility model provides a three-phase equal magnetic circuit iron core of a transformer, formed by splicing three iron core frames which are consistent in shape and size. The iron core frame is formed by reeling silicon steel plates in different width. The cross section of the iron core frame is semicircular, and the semicircular arc edge is provided with a zigzag-shaped heat radiation channel. Three iron core pillars spliced by three iron core frames are arranged in an inverted-T shape. The three-phase equal magnetic circuit iron core of a transformer is advantageous in that a zigzag-shaped heat radiation channel is provided for the heat radiation of an iron core; the silicon steel plate adopted does not require a curve cutting device; without a curve cutting and back winding process, special devices for production process and cutting are reduced, and device investment is decreased.

Technical field
The utility model relates to transformer, and a kind of magnetic circuits such as three-phase of transformer are unshakable in one's determination specifically.
Background technology
Iron core is the magnetic circuit part in the transformer, is one of the power supply quality of decision transformer and critical component of service behaviour.At present, transformer generally adopts the iron core of three post planar alignment, and this type of iron core has unequal, the unbalanced shortcoming of the length of magnetic path, is prone to produce multiple harmonic.Though and the magnetic circuit of polygon three dimensional wound core is identical, need special-purpose vertical curve open material equipment, with the silicon steel sheet slitting trapezoidal shape that meets at right angles, carry out reviewing again, roll, increased manufacturing process and equipment input, production efficiency is not high, and cost is also very high.
The utility model content
To the deficiency and the defective of above prior art, the purpose of the utility model has been to combine the unshakable in one's determination and cube polygon volume advantage unshakable in one's determination of present industry inner plane volume, and a kind of magnetic circuits such as three-phase iron core of transformer of new structure is provided.
The purpose of the utility model realizes through adopting following technical scheme:
Magnetic circuits such as a kind of three-phase of transformer are unshakable in one's determination, and this iron core is spliced and combined by three shapes, iron core frame of the same size each other; This iron core frame is processed by the silicon steel sheet continuous reeling of different in width, its cross section semicircular in shape, and this semicircular circular arc limit is provided with jagged heat dissipation channel; Three core limbs that three iron core frames splice and combine each other are " article " font and arrange.
As the optimal technical scheme of the utility model, be wound with insulating tape on the core limb of the jointing positions of said three iron core frames and fix.
With existing plane volume compared with techniques unshakable in one's determination, the utility model is made up of three shapes, iron core frame of the same size, and magnetic circuit equates; Reduced the generation of multiple harmonic, and iron core frame adopts the silicon steel sheet continuous reeling of different in width to process, its cross section is the semicircular shape; Make the core limb of transformer can effectively utilize the inner diameter volume of coil, guaranteed volumetric efficiency, with existing three dimensional wound core compared with techniques; The utility model provides jagged heat dissipation channel for heat radiation unshakable in one's determination again, simultaneously, and the silicon steel sheet that is adopted; Need not curve and open material equipment; Do not have curve to open material and reviewing operation, reduced the production process special equipment required, reduced the equipment input, improved production efficiency with opening material.

Embodiment
See also Fig. 1, be the magnetic circuits such as three-phase of the utility model transformer perspective view unshakable in one's determination.
Magnetic circuits such as this three-phase are unshakable in one's determination; Comprise the single iron core frame of processing by the silicon steel sheet continuous reeling of different in width 101; This iron core frame 101 is provided with three; Its shape, size unanimity, these three iron core frames 101 splice and combine into three core limbs each other and are the stereochemical structure that " article " font is arranged, and are wound with insulating tape 102 on the core limb of the jointing positions of these three iron core frames 101 and fix.
See also Fig. 2 and Fig. 3, be divided into the A-A generalized section of Fig. 1 and the cross sectional representation of iron core frame.The cross section of said iron core frame 101 is two semicircles 103 (being similar to), and the circular arc limit of this semicircle 103 is provided with a plurality of jagged heat dissipation channels 104.A full circle (being similar to) is formed by two identical semicircles in the cross section of three core limbs of said stereochemical structure, and the outline of the cross section of this stereochemical structure and the endoporus of middle part 105 are equilateral triangle.
Magnetic circuit iron cores such as this three-phase are made up of three shapes, iron core frame of the same size 101, and magnetic circuit equates, reduced the generation of multiple harmonic; And iron core frame 101 adopts the silicon steel sheet continuous reeling of different in width to process, and its cross section is the semicircular shape, makes the core limb of transformer can effectively utilize the inner diameter volume of coil; Guaranteed volumetric efficiency; Heat radiation for iron core provides jagged heat dissipation channel 104 again, simultaneously, and the silicon steel sheet that is adopted; Need not curve and open material equipment, reduced the production process special equipment required with opening material.
The preferred embodiment that the above is merely the utility model is not the practical range that is used for limiting the utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
