Abstract
The utility model provides a novel electric energy optimizing machine which comprises an iron core and three-phase windings which are wound on a cylinder of the iron core in a crossed mode. According to the novel electric energy optimizing machine, the three-phase windings are wound on the cylinder of the iron core in the crossed mode, and with the wiring method, the three-phase windings are not independent with one another, but form a unified system in which correlation and interaction are achieved. The windings are mutually connected in the crossed mode so that imbalance of the voltage and the currents of all phases can be eliminated, and therefore balance of the voltage and the currents of all the phases is maintained and controlled. Meanwhile, with the wiring method, higher harmonics in the system can be effectively filtered, and therefore electric equipment can operate with high quality in a state that the three-phase voltage is balanced and symmetric.

Background technology
In the ideal situation, the electric energy in electric power system is that three-phase equilibrium positive sequence sinusoidal voltage with constant frequency and amplitude is to customer power supply.But in actual motion, there is a large amount of single-phase high-power power consumption equipments, because the load of these power consumption equipments is change at random, so the amplitude of three-phase voltage, frequency, phase difference can not keep invariable, thereby very easily cause imbalance of three-phase voltage.Nonlinear-load, impact load in electric power system simultaneously day by day increase non-linear (harmonic wave), asymmetry (negative phase-sequence) and the fluctuation that cause electrical network and are on the rise, voltage, current waveform are no longer single sine waves, include high order harmonic component, electric power system is produced very adverse influence.
Power supply department is in the electric power course of conveying, and the brownout that causes for reducing voltage loss and peak of power consumption generally all adopts and puies forward high-tension mode and carry, and makes the actual voltage that bears of power load higher than its rated voltage.For power load, supply power voltage is too high not only can cause a large amount of energy wastes, also can shorten the useful life of power load.
The electric power saving transformer that extensively adopts at present is that supply power voltage is reduced to a relatively low level, has really played certain effect aspect energy-conservation, but can't have regulated imbalance of three-phase voltage, can not improve the operation conditions of power load; What adopt due to the iron core of electric power saving transformer simultaneously is common silicon steel sheet, and the no-load loss of himself is also larger, can't reach the purpose of optimizing power supply energy.
The utility model content
The purpose of this utility model is to provide a kind of three-phase voltage of can regulating to export balance, reduce load loss, saves energy, solves new electric energy uneven due to three-phase voltage output and the too high power load shortening in useful life that causes of three-phase voltage and optimizes machine.
The technical solution of the utility model is:
A kind of new electric energy is optimized machine, comprises that iron core and intersection are wound on three phase windings on iron core magnetic post.
Described new electric energy is optimized machine, and the coil head end of electromagnetic balance main winding is that supply voltage input, tail end are for optimizing voltage output end.

Described new electric energy is optimized machine, also comprises the zeroing control unit, and described zeroing control unit is connected with many groups tap of voltage-regulation auxiliary winding.
Described new electric energy is optimized the iron core of machine and is selected amorphous alloy iron core.
Three phase windings of the present utility model intersect and to be wound on iron core magnetic post, and it is no longer separate relation that this mode of connection makes between each windings of three phase windings, but forms interrelated, interactional integrated system.The mutual interconnection of winding can be eliminated the unbalanced of each phase voltage and electric current, keeps and controls its balance.Simultaneously, the high order harmonic component in all right effectively filtration system of this mode of connection makes power consumption equipment high-quality operation under the state of three-phase voltage balance, symmetry.
Preferably, three phase windings adopt electromagnetic balance main winding and the voltage-regulation auxiliary winding of self coupling to be in series, can be according to the situation of load, regulation output voltage, saves energy.
Preferably, adopt the mode of zeroing to carry out voltage-regulation, do not need to have a power failure in the process of pressure regulation, normal operation that can support equipment.
Preferably, iron core of the present utility model adopts amorphous alloy iron core, compare with the electric power saving transformer that adopts the ordinary silicon steel plate iron core, no-load loss reduction by 70%, load loss reduce more than 15%, effective saves energy, the harm that can avoid unbalanced power supply and overtension that power load is caused simultaneously.

Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of new electric energy is optimized machine, comprises a day font amorphous alloy iron core 1, intersects three phase windings 2 and zeroing control unit 3 on three magnetic posts that are wound on iron core 1.Three phase windings 1 comprise A phase winding, B phase winding, C phase winding, consist of by electromagnetic balance main winding and the series connection of voltage-regulation auxiliary winding.
The electromagnetic balance main winding of A phase winding, at first coiling on this phase iron core magnetic post, then be connected to coiling on B phase iron core magnetic post, then return to A phase iron core magnetic post again and continue coiling until complete, its coil tail end is connected with the coil head end that this phase voltage is regulated auxiliary winding; The electromagnetic balance main winding of B phase winding, at first coiling on this phase iron core magnetic post, then be connected to coiling on C phase iron core magnetic post, then return to B phase iron core magnetic post again and continue coiling until complete, its coil tail end is connected with the coil head end that this phase voltage is regulated auxiliary winding; The electromagnetic balance main winding of C phase winding, at first coiling on this phase iron core magnetic post, then be connected to coiling on A phase iron core magnetic post, then return to C phase iron core magnetic post again and continue coiling until complete, its coil tail end is connected with the coil head end that this phase voltage is regulated auxiliary winding.
The coil head end of described electromagnetic balance main winding is supply voltage input a1; B1; C1, tail end is for optimizing voltage output end a2; B2; C2, described voltage-regulation auxiliary winding contain the taps 4 of many groups, and zeroing control unit 3 is corresponding to be contained a plurality of switch elements 5 and be connected with many groups tap 4 of voltage-regulation auxiliary winding respectively, thereby forms multiple output transformation ratio.
Operation principle of the present utility model:
Because the coil of the electromagnetic balance main winding of three phase windings 2 that are connected with supply voltage is to intersect on three magnetic posts that are wound on iron core 1, when certain phase voltage raises, when the magnetic flux increase of this phase winding coil causes three-phase magnetic flux imbalance to occur, the magnetic flux of other two phase coils on the iron core magnetic post in same magnetic circuit will increase automatically, to keep the balance in magnetic circuit, this just makes the self induction electromotive force in other two phase coils automatically increase, thereby makes three-phase mains voltage keep each other balance; According to the situation of load, zeroing control unit 3 is controlled corresponding switch element 5 closures, regulation output voltage, saves energy.
