Technical field
The utility model relates to the technical field of three-phase iron core, refers in particular to a kind of 3-D triangle open mouth knuckle unshakable in one's determination.
Background technology
In current transformer industry, three-phase primary structure unshakable in one's determination is plane laminated core structure (as shown in Figure 5), plane wound core (amorphous alloy core) structure (as shown in Figure 6), three-phase stereo rewinding material (as illustrated in figs. 7 a and 7b); Plane laminated core structure consumptive material is more, does not reach energy-saving effect; Plane wound core is square structure, and noise is high, anti-sudden short circuit ability; 3-D triangle is remained silent and is rolled up complex process in iron core production process, needs annealing, due to coil directly coiling on iron core after iron core has rolled, design to be considered the installation of winding former, therefore design space utilance is lower, and practicality is not strong, is only limitted to use in miniature transformer.On the whole, this several structure to there is cost high, technological requirement is high, and design space utilance is low, the respective shortcoming such as the high and anti-short circuit capability of noise is poor.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide that a kind of compact conformation is reliable, cost is low, technological requirement is low, suit is simple, noise is little, no-load loss is little, design space utilance is high, energy-conserving and environment-protective and the strong 3-D triangle open mouth knuckle of anti-short circuit capability unshakable in one's determination.
For achieving the above object, technical scheme provided by the utility model is: a kind of 3-D triangle open mouth knuckle is unshakable in one's determination, the described 3-D triangle open mouth knuckle rewinding material frame by three identical independent openings unshakable in one's determination forms by central angle hexagonal angle assembling combination, form closed 3-D triangle magnetic circuit, the vertical portion bit combination of rewinding material frame adjacent is between two formed as the stem of 3-D triangle open mouth knuckle iron core, above-mentioned three rewinding material frames have been combined to form three stems altogether, wherein, described rewinding material frame is formed by iron yoke and analog-U shaped iron core assembling combination, opening on the shape size of described iron yoke and analog-U shaped iron core matches, and be assemblied in this opening part, the both sides of described analog-U shaped iron core are respectively installed with winding.
The cross-sectional area sum of described iron yoke and analog-U shaped iron core is 1/2 of stem cross-sectional area.
The cross section of described stem is the multistage step close to circle.
Compared with prior art, tool has the following advantages and beneficial effect the utility model:
1, fold iron core compared to plane, the cross-sectional area of iron yoke of the present utility model and analog-U shaped iron core is 1/2 of stem cross-sectional area, and the weight of total iron core weight 1 centre-to-centre spacing fewer than plane laminated core, has saved core material cost greatly;
2, to remain silent volume iron core compared to 3-D triangle, mounting coil technique of the present utility model is identical with plane laminated core, and design does not need the installing space considering winding former, therefore more compact structure, reduce further material cost;
3, stem cross section is the multistage step close to circle, substantially increases transformer anti-short circuit capability, improves the performance level of product;
4, because coil can coiling separately, suit technique is identical with plane laminated core, therefore design capacity and voltage unrestricted, can be widely used in all three-phase transformer products.

Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figures 1 to 4,3-D triangle open mouth knuckle described in the present embodiment is unshakable in one's determination, formed by central angle hexagonal angle assembling combination by the rewinding material frame 1 of three identical independent openings, form closed 3-D triangle magnetic circuit, simultaneously, the vertical portion bit combination of rewinding material frame 1 adjacent is between two formed as the stem 2 of 3-D triangle open mouth knuckle iron core, above-mentioned three rewinding material frames 1 have been combined to form three stems 2 altogether, the cross section of described stem 2 is the multistage step close to circle, substantially increase transformer anti-short circuit capability, improve the performance level of product; Described rewinding material frame 1 is formed by iron yoke 101 and analog-U shaped iron core 102 assembling combination, and the opening on the shape size of described iron yoke 101 and analog-U shaped iron core 101 matches, and is assemblied in this opening part, and the both sides of described analog-U shaped iron core 101 are respectively installed with winding 103.In addition, the cross-sectional area sum of described iron yoke 101 and analog-U shaped iron core 101 is 1/2 of stem 2 cross-sectional area.
In sum, the utility model combines laminated core and solid and to remain silent rewinding material advantage separately, adopts 3-D triangle open mouth coiling structure, this compared to existing technology, the utility model has the following advantages:
1, fold iron core compared to plane, the cross-sectional area of iron yoke of the present utility model and analog-U shaped iron core is 1/2 of stem cross-sectional area, and the weight of total iron core weight 1 centre-to-centre spacing fewer than plane laminated core, has saved core material cost greatly;
2, to remain silent volume iron core compared to 3-D triangle, mounting coil technique of the present utility model is identical with plane laminated core, and design does not need the installing space considering winding former, therefore more compact structure, reduce further material cost;
3, stem cross section is the multistage step close to circle, substantially increases transformer anti-short circuit capability, improves the performance level of product;
4, because coil can coiling separately, suit technique is identical with plane laminated core, therefore design capacity and voltage unrestricted, can be widely used in all three-phase transformer products.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection range of the present utility model.
