Abstract
The invention discloses the three-phase reactor of a kind of inductance balance, including E font iron core, E font iron core includes the first phase iron core, the second phase iron core and the third phase iron core being parallel to each other, being arranged in order；The length of the first phase iron core, the second phase iron core and third phase iron core is the most equal with cross-sectional area；Described second phase iron core has the gap structure of hollow；Described gap structure is filled with soft block object.The present invention increases air gap to stalloy center pillar, then fills with soft block object, can guarantee that product does not produce whistle in using, make EMC and EMI of product unaffected.
Description
Technical field
The present invention relates to reactor, be specifically related to the three-phase reactor of a kind of inductance balance.
Background technology
Due to the design reasons of three-phase reactor, the phase in the middle of reactor, inductance value can than side biphase high 10%-
15%, the voltage that so can cause product is inconsistent.
Summary of the invention
For the deficiencies in the prior art, the invention discloses the three-phase reactor of a kind of inductance balance.
Technical scheme is as follows:
The three-phase reactor of a kind of inductance balance, including E font iron core, E font iron core includes being parallel to each other, being arranged in order
The first phase iron core, the second phase iron core and third phase iron core；First phase iron core, the second phase iron core and the length of third phase iron core
The most equal with cross-sectional area；Described second phase iron core has the gap structure of hollow；Described gap structure is filled with soft
Block object.
Its further technical scheme is, described second phase iron core disconnects from cross-section becomes described gap structure, with
The cross section of described second phase iron core is parallel.
Its further technical scheme is, is provided with gap, with described second in the middle of the vertical plane of described second phase iron core
The cross section of phase iron core is perpendicular, forms described gap structure.
Its further technical scheme is, described soft block object is silica gel, plastic cement or resin.
The method have the benefit that:
The present invention increases air gap to stalloy center pillar, then fills, in can guarantee that product uses with soft block object
Do not produce whistle, make EMC and EMI of product unaffected.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of one embodiment of the present of invention.
Fig. 2 is the schematic diagram of an alternative embodiment of the invention.
Detailed description of the invention
Fig. 1 is the schematic diagram of one embodiment of the present of invention.The present invention includes that E font iron core 1, E font iron core include phase
The most parallel, be arranged in order the first phase iron core the 11, second phase iron core 12 and third phase iron core 13；First phase iron core 11, second
The length of phase iron core 12 and third phase iron core 13 is the most equal with cross-sectional area；Second phase iron core 12 has the gap structure of hollow
2；Gap structure 2 is filled with soft block object.As it is shown in figure 1, be provided with gap in the middle of the vertical plane of the second phase iron core 12,
Perpendicular with the cross section of the second phase iron core 12, form gap structure 2.
Fig. 2 is the schematic diagram of an alternative embodiment of the invention.Gap structure also can have an another embodiment, and i.e. second
Phase iron core 12 disconnects from cross-section becomes gap structure 2, parallels with the cross section of the second phase iron core 12.
Soft block object is silica gel, plastic cement or resin.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above example.It is appreciated that this
Skilled person the most directly derive or associate other improve and become
Change, within being all considered as being included in protection scope of the present invention.
