Abstract

The invention relates to a power-saving winding using a combined ferrite iron core for saving power in the electricity grid. In the power-saving winding, a Z-shaped winding form is adopted to wind three coils on a square iron core with a middle line, i.e. two ends of the first coil are winded on the left pillar of the iron core, and the middle section is winded on the middle pillar of the iron core; two ends of the second coil are winded on the middle pillar of the iron core, and the middle section is winded on the right pillar of the iron core; two ends of the third coil are winded on the right pillar of the iron core, and the middle section is winded on the left pillar of the iron core. The iron core of the winding is formed in such a way that five rectangular ferrite iron cores are adhered or tied together. The winding made by the winding way has high magnetic flux density, large capacity and small volume, and can correct bias wave, reduce neutral current, reach the effect of removing upper harmonics and adjusting three-phase balance, can save power and improve service life of the electric facilities.

Description

Adopt the economize on electricity winding of combined ferrite iron core

Affiliated technical field

The present invention relates to a kind of winding, especially can be in electric power networks the economize on electricity winding of the employing combined ferrite iron core of saves energy.

Background technology

The application is the technological innovation on my patent CN201036135 basis.At present, ubiquity high order harmonic component in the electric power networks, causes alternating current to be difficult to guarantee the desirable balance of phase voltage and phase current in actual moving process.High order harmonic component and imbalance not only cause waste of energy, also can reduce the efficient and the life-span of power consumption equipment.The basic waveform of alternating current is sinusoidal wave, and high order harmonic component and imbalance can cause askew ripple, thereby increases impedance and cause electric current to descend, and load will consume more electric current in order to satisfy original power, causes unnecessary power consumption.But the winding in the existing network can not be eliminated high order harmonic component, can not regulate three-phase equilibrium, has caused waste of electric energy to a great extent.

Traditional transformer core is mainly by ferrite magnetic material and two kinds of material of silicon steel sheet.The transformer core that ferrite is formed has the high performance of magnetic flux density, but because its sintering manufacturing process restriction, can not direct sintering produces the big capacity iron core that large volume and shape meet the winding requirement.Therefore be mainly used to make small capacity transformer at present.Though silicon steel sheet can be made jumbo transformer core, because the silicon steel material performance limitations, magnetic flux density is lower, can not adapt to this development in science and technology trend of transformer high frequencyization.Therefore traditional transformer core has hindered the paces of power electronics industry to high frequencyization, big capacity development.

Summary of the invention

The object of the present invention is to provide a kind of economize on electricity winding that adopts combined ferrite iron core, the high order harmonic component that exists in the existing electric power networks can't be eliminated and the shortcoming of three-phase imbalance to solve.

Technical scheme of the present invention is achieved in that the economize on electricity winding that adopts among the CN201036135, and first coil 1, second coil 2, tertiary coil 3 adopt the winding mode of zigzag to be wrapped on the square shape iron core 4 of band center line in this winding.Promptly the two ends of first coil 1 are wrapped in the left post of iron core 4, and interlude is wrapped in the center pillar of iron core 4; The two ends of second coil 2 are wrapped in the center pillar of iron core 4, and interlude is wrapped in the right post of iron core 4; The two ends of tertiary coil 3 are wrapped in the right post of iron core 4, and interlude is wrapped in the left post of iron core 4.

The iron core 4 of winding is to be combined by 5 independent rectangle ferrite iron cores, and the compound mode of these 5 rectangle ferrite iron cores can be bonding or binding.

The invention has the beneficial effects as follows:

The winding correction of making of this winding mode askew ripple, reduced neutral current, reach the effect of eliminating high order harmonic component, regulating three-phase equilibrium, simultaneously can saves energy, the useful life of improving power consumption equipment;

Adopt and to make that the magnetic flux density height of winding, capacity are big, volume reduces behind the combined ferrite iron core.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Accompanying drawing 1 is an economize on electricity winding construction schematic diagram of the prior art

Accompanying drawing 2 is decomposing schematic representations of the combined ferrite iron core structure of this economize on electricity winding employing

1. first coils among the figure, 2. second coil, 3. tertiary coil, 4. iron core, (R, r, S, s, T, t represent the phase place of each coil respectively) 5. is combined into 5 rectangle ferrite iron cores of iron core 4

Embodiment

In Fig. 1, first coil 1, second coil 2, tertiary coil 3 adopt the winding mode of zigzag to be wrapped on the iron core 4.Promptly the two ends of first coil 1 are wrapped in the left post of iron core 4, and interlude is wrapped in the center pillar of iron core 4; The two ends of second coil 2 are wrapped in the center pillar of iron core 4, and interlude is wrapped in the right post of iron core 4; The two ends of tertiary coil 3 are wrapped in the right post of iron core 4, and interlude is wrapped in the left post of iron core 4.Utilize mutual balancing by transposition to come control coil between them, produce and the antipodal waveform of high order harmonic component phase place, make it to cancel out each other, thereby revised askew ripple, reduced neutral current, reach the effect of eliminating high order harmonic component, regulating three-phase equilibrium, saved electric energy simultaneously, can significantly improve the useful life of power consumption equipment.

In Fig. 2,5 independent rectangle ferrite iron cores have been combined into the iron core 4 of winding by mode bonding or binding, make that the winding iron core magnetic flux density height, the capacity that are combined into are big, volume reduces.
