Abstract
The utility model discloses a three -phase reactor with mix magnetic circuit, including upper and lower indisputable yoke with install at the three -phase stem stem between the upper and lower indisputable yoke and install the three -phase coil on the three -phase stem stem, upper and lower indisputable yoke that its upper and lower indisputable yoke adopted silicon steel sheet to make, the three -phase stem stem adopts low -loss metal powder heartwood to expect the three -phase stem stem that indisputable silicon was made. The utility model discloses a stem stem adopts the indisputable silicon of low -loss metal powder heartwood material, because indisputable silicon magnetic conductivity is low, contains the distribution air gap to air gap in the stem stem reduces can not have the air gap even by a wide margin. The iron yoke adopts the silicon steel sheet, because the silicon steel sheet magnetic conductivity is high, can guarantee the uniformity of three -phase inductance value. The beneficial effects of the utility model are that: 1. Use indisputable silicon in the stem stem for the air gap is little, and the magnetic leakage is low, and the high -frequency loss is little, and is efficient. 2. Because indisputable silicon material loss is low, just can select less magnetic core in the design to reduce the reactor volume, the optimization cost. 3. The uniformity of three -phase inductance is good.
Description
Technical field
The utility model relates to three-phase reactor technical field, particularly a kind of three-phase reactor with mixed magnetic circuit.
Background technology
At the common usage of the three-phase reactor applied in the market be: whole magnetic circuit all selects silicon steel sheet as core material, and in stem stem, add air gap adjustment inductance value.The advantage of this magnetic core is that structural manufacturing process is simple, and shortcoming is owing to there is more air gap in stem stem, produces very strong leakage field effect, causes core loss sharply to increase.In applied power electronics occasion, silicon steel sheet class reactor ubiquity loss greatly, the shortcoming that product is large.Along with high-power high-frequency rate combining inverter is in the extensive use of new forms of energy industry, traditional inferior position such as three-phase reactor volume, cost, loss is more remarkable, seriously governs the development of electronic power convertor.How optimizing three-phase reactor cost, volume, efficiency, is reactor manufacturer problem in the urgent need to address.
Utility model content
Technical problem to be solved in the utility model provides a kind of three-phase reactor with mixed magnetic circuit for the above-mentioned technical problem existing for existing three-phase reactor, and it, by reconfiguring magnetic circuit, reduces the wastage, reduce volume and reduce costs.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of three-phase reactor with mixed magnetic circuit, the three-phase stem stem comprising upper and lower iron yoke and be arranged between described upper and lower iron yoke and the three-phase coil be arranged on described three-phase stem stem, it is characterized in that, the upper and lower iron yoke that described upper and lower iron yoke adopts silicon steel sheet to make, the three-phase stem stem that described three-phase stem stem adopts low-loss metal powder heartwood material iron silicon to make.
The utility model is in three-phase reactor in iron core combination, and stem stem adopts low-loss metal powder heartwood material iron silicon, and because iron silicon magnetic permeability is low, containing distributed air gaps, thus the air gap in stem stem significantly reduces even can not have air gap.Iron yoke adopts silicon steel sheet, because silicon steel sheet magnetic permeability is high, can ensure the consistency of three-phase electricity sensibility reciprocal.
The beneficial effects of the utility model are: 1. use iron silicon in stem stem, and make air gap little, leakage field is low, and high-frequency loss is little, and efficiency is high.2. because the loss of iron silicon materials is low, design just can select less magnetic core, thus reduce reactor volume, Cost optimization.3. the consistency of three pole reactor is good.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation with the three-phase reactor of mixed magnetic circuit of the present utility model.
Embodiment
See Fig. 1, a kind of three-phase reactor with mixed magnetic circuit provided in figure, the three-phase stem stem 300,400,500 comprising upper and lower iron yoke 100,200 and be arranged between upper and lower iron yoke 100,200 and the three-phase coil 310,410,510 be arranged on three-phase stem stem 300,400,500, the upper and lower iron yoke that upper and lower iron yoke 100,200 adopts silicon steel sheet to make, can guarantee the consistency of three pole reactor.The three-phase stem stem that three-phase stem stem 300,400,500 adopts low-loss metal powder heartwood material iron silicon to make, thus reduce stem stem loss, reduce reactor volume, Cost optimization.
