Our country develops in domain of electric power electron in last few years rapid, particularly in linear of Central Africa of power supply network bear system is like deflector, electric machinery the equipment using phone such as system of lighting of commutate of electron of equipment of electron of equipment of device of stabilized voltage of saturation of the soft device that start, magnetism, large commutate, communication equipment, medical treatment, large supermarket, these equipment move in electric power circuit will cause voltage weaveform distortion, produce Gao Cixie wave to pollute system of electrified wire netting, reduce power factor, increase ripple, its harm is very serious, the harm that harmonic produces basically is:
Electric machinery movement increases organ and loss, reduce efficiency, generation backset, temperature rise rises, quicken insulation ageing, reduce service life.
Harmonic can make the electric power capacitor in having merit compensation device, reactor produces harmonic enlarge, produce harmonic vibration, enlarge voltage, puncture capacitor, cause short circuit explosion, lead to fire, endanger equipment person security.
Harmonic can disturb communication circuit, affect the regular job of the computer and accurate instrument equipment.
Harmonic can disturb electric parameter, cause relay protector piles up a movement by accident, endanger safety of electrified wire netting to move.
Harmonic can make misoperation of equipment of a few computers that use phone, lose the accuracy of metric numerical value.

Use many reactor generally domestic and internationally to restrain harmonic at present, its reactor uses silicon steel piece fold install and become, as a result of silicon steel piece the biggest guide magnetism leads Um to be 12000 gauss only, to Gao Cixie baud fastens pair of 5 above harmonic to present magnetism saturation appearance, cannot remove inhibition, produce incentive overvoltage instead, attaint capacitor, and volume amount is significant, production cost is higher.

For from go up at all solve this technology difficult problem, our company pass own innovation, via 2 years of much research and development, successful EXB-Q harmonic restrains trial-produce implement. This product was overcome country is at present common those who use is hollow the type that wind a string and silicon steel piece the inadequacy that reactor restrains harmonic, use the accept rice material that guides magnetism is led high to replace silicon steel piece, its guide magnetism leads Ui to be able to achieve 80000-100000 above, it is at present optimal guides magnetism material, the harmonic that makes with its is restrained implement volume is minor, the price is low the 1/5 that is former reactor cost, on circuit application restrains harmonic effect remarkable, can restrain harmonic of 3-9 second above. Because use circuit of three-phase closed circuit, do not have the sources of energy to use up, without electromagnetism radiate, return the result that can achieve energy-saving section material.
