Abstract
The utility model discloses a three-phase magnetic voltage regulator, which is used for the fields, such as the electric drive, the metallurgy, the petrochemical industry, etc. The iron core of the three-phase magnetic voltage regulator is inserted and stacked to be the three-dimensional structure of the full and symmetrical space of the three-phase iron core pole with a silicon steel sheet, and simultaneously, the primary coils and the secondary coils are crosswise arranged on the iron core pole of each phase. In addition, an adjustable magnetic shunt path controlled by a direct current magnetic field is arranged between the primary coils and the secondary coils. The three-phase magnetic voltage regulator which can be widely applied in a plurality of fields has the advantages of simple structure, small waveform distortion, small time constant, small size, material saving, and reduced energy consumption.
Description
The utility model relates to a kind of three-phase magnetic voltage regulator that is used for Electric Traction, metallurgy, field of petrochemical industry.
, have only single-phase magnetic voltage regulator the magnetic circuit of transformation and saturable reactor organically can be formed one both at home and abroad at present.And the three-phase magnetic voltage regulator so far at home and abroad, and not retrieving as yet can be with the technical scheme of transformer and magnetic saturation reactor organic composition one.The frame mode of existing three-phase DC excitation regulator has two kinds: a kind of is to transfer device to form a three-phase magnetic accent group with three single-phase magnetic; Another kind is mechanically to be formed by connecting with the logical three-phase transformer of a Daepori and one group of three-phase magnetic saturation reactor.The three-phase DC excitation regulator that this dual mode is combined into, volume are all very big, consume material is many, and structure is all very complicated, make difficulty, and cost is higher, and iron loss is very big, and its capacity is restricted, and the scope of application is also narrower.
The purpose of this utility model is to avoid above-mentioned art weak point of the prior art, and provides a kind of wave distortion little, and time constant is little, and volume is little, and is simple in structure, not only material-saving but also energy-conservation three-phase magnetic saturation by-passing type magnetic voltage regulator.
The purpose of this utility model reaches by following measure: the iron core of this voltage regulator be with silicon steel sheet insert build up its cross section be "
" shape, and the three-phase core limb becomes holosymmetric space multistory structure; On each phase core limb, primary and secondary coil is staggeredly placed simultaneously; And between primary and secondary coil, be provided with adjustable magnetic shunt again with D.C. magnetic field control.
The utility model can be that a direct current centralized control winding is set between the primary and secondary coil of three-phase with the adjustable magnetic shunt of D.C. magnetic field control.
The utility model can be that a direct current phase-splitting control winding is set respectively between the primary and secondary coil of three-phase separately with the adjustable magnetic shunt of D.C. magnetic field control.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structure chart of the utility model centralized control.
Fig. 2 is a kind of structure chart of the utility model phase-splitting control mode.
Fig. 3 is the another kind of structure chart of the utility model phase-splitting control mode
Fig. 4 is the cross-sectional view of the utility model iron core.
The utility model is described in further detail below in conjunction with embodiment: the iron core of this magnetic voltage regulator (1) be with silicon steel sheet insert build up its cross section be "
" shape; and three-phase core limb (1-1) becomes holosymmetric space multistory structure; simultaneously on each phase core limb (1-1); primary coil (2) and secondary coil (3) they are to place alternately, and a public adjustable magnetic shunt (4) that is made of direct current centralized control winding (5) is set between the primary and secondary coil of three-phase (2,3).The adjustable magnetic shunt (4) that a direct current phase-splitting control winding (6) is formed also can be set respectively between the primary and secondary coil of three-phase (2,3) in addition separately.
When this magnetic voltage regulator uses, as long as change the direct current size in the DC control winding, just can change the magnetic resistance of magnetic shunt, thereby regulated in the core limb size with the main flux of secondary coil linkage, that is to say the degree of coupling that has changed primary and secondary coil, thereby realized the purpose of pressure regulation.
The utility model has following advantage compared to existing technology: this magnetic voltage regulator is not owing to there is reactance coil, thereby its time constant is little, wave distortion is little, compare with the Combined type magnetic pressure regulator of equal capacity and not only can save material more than 30%, and volume is little, and is simple in structure, reduces energy consumption, it can make the furnace transformer of various uses, various rectifier transformer and Three-phase high-power voltage-stabilized power supply, can use in every field.
