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 kunye nokuguga 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.
