Iziphumo eziphambili ze-harmonics

I-Harmonics ibonakala ngakumbi nangakumbi kubomi bethu bemihla ngemihla.Ukufumana ubukho obuphezulu be-harmonics ngokuqhelekileyo ezibhedlele, iiyunivesithi, amaziko karhulumente, amaziko okuthenga, iilebhu, amashishini anzima, unomathotholo, umabonwakude, usasazo, ishishini lokutya, ihotele kunye nekhasino, ishishini elizenzekelayo kakhulu, izityalo zokucoca amanzi. izixhobo eziqhelekileyo zokuvelisa i-harmonic eziquka: ukutshintshela izixhobo zamandla, iiwelders, ii-Ups, isiguquli esidala se-frequency converter ngeteknoloji yokuguqula amandla e-thyristor, ii-motor drives, iziguquli ezinee-rectifiers ezilawulwayo, isilawuli se-DC se-DC drives, ii-oveni zokungeniswa.
Iziphumo eziphambili ze-harmonics zingezantsi:
1.Ukushisa okugqithisileyo kunye nokungcangcazela ngokuguga kwangaphambili kwawo onke amalungu, kunye neziphumo zexesha elifutshane kunye nexesha eliphakathi kubomi obulindelekileyo.
2.Iimpazamo kwizixhobo zombane zombane.
3.Umonakalo kumacandelo ebhodi yesekethe eprintiweyo.
4.Electric motor overload.
I-5.I-capacitors yokuguga kwangaphambili kunye nomonakalo ngenxa ye-resonance.
6.Ukunciphisa into yamandla.
7.Ukugqithiswa kwentambo engathathi hlangothi.
8.Impembelelo ye-electromagnetic.
9.Iimpazamo zokulinganisa kwiimitha zamandla.
I-10.MCCB kunye ne-contactor interruption fault.
11.Ukukhubeka okungalunganga kokutshintsha.
Izihluzi zeharmonic ezisebenzayozizixhobo zomgangatho wamandla ezibonelela ngamandla ngoku ukulawulwa kwangoku okune-amplitude efanayo ne-harmonic yangoku, efakwe ngokuchasene ne-harmonics kwinethiwekhi.Oku kuya kuphelisa i-harmonic current kwinkqubo yombane.Ngenxa yoko, ikhoyo ngoku enikezelwa ngumthombo wamandla iya kuhlala i-sinusoidal njengoko i-harmonics iya kukhansela enye kunye kunye nokuphazamiseka kwe-harmonic kuya kuncitshiswa kwixabiso eliphantsi kakhulu.
Izihluzi ezisebenzayoinokufakwa naphi na kwinethiwekhi kwaye ibonelele ngezinto ezininzi:
1.Ukuphelisa yonke imisinga ye-harmonic ukuya kwi-oda ye-50 ukusuka kwimithwalo engeyiyo yomgca.
2.Buyisela amandla asebenzayo kwaye ulungise into yamandla.
3.Buyekeza i-flicker ebangelwa ngamandla asebenzayo.
Noker Electricisihluzo samandla asebenzayoyamkela obona buchwepheshe buphezulu bemigangatho emithathu, eneempawu zobukhulu obuncinci, ukuxinana kwamandla aphezulu, ukusebenza okuzinzileyo nokuthembekileyo, okuthandwa ngabathengi. Imbuyekezo, i-harmonic frequency ukusuka kwi-3 ukuya kwi-50 ye-harmonic, inokunyusa ukwenziwa komgangatho wegridi yakho.
