Ma Harmonics mumagetsi amagetsi amachokera ku zida zamagetsi, ndiko kuti, kuchokera ku zida zopangira ndi zida zamagetsi.
Gwero la 1.Harmonic (gwero la harmonic kumapeto kwa magetsi nthawi zambiri limalozera ku zipangizo zamagetsi zomwe zimalowetsa mphamvu yamagetsi mu gridi ya anthu onse kapena kupanga magetsi a harmonic mu gridi ya anthu onse).Zida zina zopanda mzere zidzapanga ma harmonics akamagwira ntchito mu gridi.Mwachitsanzo, rectifiers single-gawo, ng'anjo magetsi arc, rectifiers, inverters, frequency converters, arc kuwotcherera makina, induction zipangizo kutentha, electromechanical zipangizo ndi maginito saturation, etc. Harmonics opangidwa ndi zipangizo zamagetsi, makamaka rectifier thyristor zipangizo, amagwiritsidwa ntchito mu ma locomotives amagetsi, ma electrolyzer a Lu, magetsi osinthira, etc., ndipo ali ndi ntchito zambiri.Zida zambiri za rectifier thyristor zimatengera kuwongolera kwa gawo, kotero zimasiya ma harmonics ambiri ku gridi yamagetsi.Malinga ndi ziwerengero zaukadaulo waukadaulo, ma harmonics opangidwa ndi chipangizo cha rectifier amawerengera 40% ya ma harmonics onse, ndipo nthawi zambiri amadziwika ngati gwero lalikulu kwambiri la ma harmonics.Zida zosinthira pafupipafupi zimatengera kuwongolera magawo, kotero kuti ma harmonics opangidwa amakhala ovuta kwambiri, nthawi zambiri kuphatikiza ma harmonics ophatikizika ndi ma harmonics ochepa.Chifukwa cha mphamvu yayikulu ya zida zosinthira pafupipafupi, zomwe zimapangidwa ndi harmonic zidzawonjezekanso.Komanso zida zamagetsi zapakhomo, chifukwa ambiri aiwo ali ndi zida zowongolera ndi kukonza ma voltage, apanganso ma harmonics ozama.Panthawi imodzimodziyo, kusintha kosasinthika kwamakono kudzachititsanso kusintha kwa mawonekedwe a waveform.Chifukwa cha kuchuluka kwa zida zapakhomo, kuchuluka kwa ma harmonics opangidwanso ndikwambiri.Ambiri aiwo akusintha zida zamagetsi pogwiritsa ntchito zida zamagetsi zamagetsi.
2. Njira yotumizira ndi kugawa yokha idzapanganso ma harmonics.Gwero lalikulu la ma harmonics ndi chosinthira mphamvu.Chifukwa cha machulukitsidwe a thiransifoma pachimake, magnetizing panopa kusonyeza nsonga yoweyula mawonekedwe, ndiye ma harmonics wosamvetseka.Kuchuluka kwa machulukidwe a thiransifoma pachimake, ndikokulirapo kwa ma harmonic komanso kumapangitsa kuti ma harmonic apangidwe.Ndi ya chipangizo chapakati chachitsulo chokhala ndi mawonekedwe a ferromagnetic saturation.
3. The mphamvu m'badwo gwero n'zovuta kukwaniritsa mtheradi wangwiro symmetry mu luso mu msonkhano ndi kupanga atatu gawo mapiringidzo a anapereka jenereta, ndi pachimake chitsulo pa jenereta sangathe kwathunthu yunifolomu khalidwe ndi kapangidwe, etc., kubweretsa ubwino wa mphamvu yopangidwa.osati mkulu, kumabweretsa ma harmonics.
4. Gasi kutulutsa magetsi magetsi gwero.Mwachitsanzo, nyali za fulorosenti, nyali zothamanga kwambiri za sodium, nyali zachitsulo za halide, ndi zina zotero, chifukwa cha kusagwirizana kwawo kwakukulu, zidzachititsanso mafunde osamvetseka ku gridi yamagetsi.Ndi ya zida zokhala ndi arc ngati sing'anga yogwirira ntchito yokhala ndi mawonekedwe amphamvu osagwirizana.
Pofuna kuchepetsa ma harmonics mu dongosolo la mphamvu.Nthawi zambiri, kuchuluka kwa kugunda kwa chipangizo chosinthira kumachulukitsidwa ndipo fyuluta ya AC imayikidwa.Limbikitsani kasamalidwe ka ma harmonic.The mkulu ndi otsika voteji zotakasuka mphamvu chipukuta misozi chipangizo opangidwa ndi Hongyan Electric, mkulu ndi otsika voteji Integrated capacitor chipangizo ndi mkulu ndi otsika voteji zotakataka mphamvu zosunthika ndi malo amodzi fyuluta chipukuta misozi ndi zida zodalirika kwambiri zochepetsera zoopsa harmonic.
