Embodiment Construction

[0014] exist figure 1 Among them, the first coil 1 , the second coil 2 and the third coil 3 are wound on the iron core 4 in a zigzag winding manner. That is, the two ends of the first coil 1 are wound on the left column of the iron core 4, and the middle section is wound on the middle column of the iron core 4; the two ends of the second coil 2 are wound on the middle column of the iron core 4, and the middle section is wound on the iron core The right column of 4; the two ends of the third coil 3 are wound on the right column of the iron core 4, and the middle section is wound on the left column of the iron core 4. They use mutual cross balance to control the coil, generate waveforms that are completely opposite to the phase of the high-order harmonics, and cancel each other out, thereby correcting the crooked waves, reducing the neutral line current, and eliminating high-order harmonics. The effect of phase balance, while saving electric energy, can significantly improve th...

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

Technical field [0001] The invention relates to a winding, in particular to a power-saving winding using a combined ferrite core capable of saving electric energy in a power network. Background technique [0002] This application is a technological innovation based on my patent CN201036135. At present, high-order harmonics are common in the power network, which makes it difficult to ensure the ideal balance of phase voltage and phase current in the actual operation of AC power. High-order harmonics and imbalance not only cause waste of electric energy, but also reduce the efficiency and life of electrical equipment. The basic waveform of alternating current is a sine wave, and high-order harmonics and imbalances will cause skewed waves, which will increase the impedance and cause the current to drop, and the load will consume more current in order to meet the original power, resulting in unnecessary power consumption . However, the windings in the existing network cannot ...
