Uhlalutyo lwempembelelo ye-harmonics kumandla ombane

Imithombo yeeharmonics

Zininzi izizathu zokuveliswa kweeharmonics, ngoko ke zininzi kakhulu, kwaye iintlobo zezixhobo ezibandakanyekayo nazo zibonisa iimpawu ezithile ezahlukeneyo. Phakathi kwazo, imithombo ephambili yeeharmonics ibandakanya amaqela e-transformer kwigridi yamandla, ii-arc zombane zemizi-mveliso, izixhobo ze-elektroniki ezinkulu zamandla zesigaba esinye, kunye noluhlu olubanzi lwezixhobo zokulungisa kunye nezixhobo zokulawula i-AC voltage.

Uhlalutyo oluyingozi lweeharmoniki

Ubukho beeharmonics kwinkqubo yamandla bulingana nomthombo wongcoliseko lwenkqubo yamandla, kwaye into yongcoliseko ikakhulu yindawo ye-electromagnetic kwinkqubo yamandla. Njengenxalenye ebalulekileyo yokusingqongileyo kwenkqubo yamandla, indawo ye-electromagnetic iya kubonisa iingozi ezahlukeneyo phantsi kwempembelelo yamanqanaba ahlukeneyo e-harmonics. Nangona kunjalo, olu bungozi bungako buya kunciphisa ukusebenza kakuhle kwezixhobo zombane, kwaye iziphumo ezibi kakhulu zinokukhokelela ekutshutshisweni kokusebenza okuzinzileyo nokukhuselekileyo kwenkqubo yamandla kunye nomonakalo kwizixhobo zombane. Umonakalo ekuvelisweni kwe-harmonic ubandakanya ngokukodwa ezi zinto zilandelayo:

(1) Izixhobo zombane zishushu ngokungaqhelekanga xa zisebenza ngeeharmonics, kwaye ilahleko eyongezelelweyo inkulu kakhulu. Nangona kukho umsantsa omkhulu phakathi kobungakanani bombane weharmonics kunye nombane osisiseko, ubukho beeharmonics buya kwenza kube nzima ukusebenza kwesikhumba sesixhobo, kwaye ukumelana okusebenzayo kuya kwanda kwinkqubo yokuva isiphumo sesikhumba. Kwezinye izixhobo ezikhethekileyo, ilahleko enkulu yombane we-eddy kunye nelahleko ye-hysteresis nayo iya kwenzeka, njengezixhobo zombane ezineentsimbi. Xa i-waveform ijijekile ukuya kwinqanaba elithile, i-amplitude peak wave enkulu iya kwandisa amandla okukhupha okuncinci. Phantsi kweemeko ezinjalo zokusetyenziswa okuphezulu, kulula ukunciphisa ubomi benkonzo yezixhobo zombane.

(2) Injini inokubangela ukungcangcazela koomatshini. Phantsi kwempembelelo ye-harmonic currents, i-magnetic field ejikelezayo yenjini iya kuvelisa i-pulsating torque enokubangela ukuba imoto ingcangcazele. Phantsi kwempembelelo ye-frequency yendalo yenjini, olu hlobo lokungcangcazela lunokubangela ukungcangcazela koomatshini okuyingozi ngakumbi, ngaloo ndlela lubeka emngciphekweni umgangatho wezixhobo zombane kwaye lude lusongele ubomi babantu.

(3) Ukuphazamiseka kwezixhobo zekhompyutha kunye nezinye izixhobo zokulawula ngokuzenzekelayo. Kwiimeko eziqhelekileyo, izixhobo zokulawula ngokuzenzekelayo kunye nezinye iinkqubo zokulawula ngokuzenzekelayo ezinxulumene nazo ziyilwe ngokusekelwe kumbane oqhelekileyo wamandla kunye nombane olayishiweyo. Xa kuveliswa iiharmonics, inkqubo yolawulo ngokuzenzekelayo ayithatheli ngqalelo le nto inefuthe, okwenza kube lula Ukuphazamiseka kuchaphazela ukusebenza komsebenzi wayo wokulawula. Xa inqanaba longcoliseko lweeharmonics likhulu, kunokwenzeka ukutshintsha iinkqubo zokusebenza kwenkqubo yolawulo ngokuzenzekelayo, okubangela ukuba ivelise ulwalathiso olungalunganga. Olu hlobo lwempembelelo luya kuchaphazela kakhulu imveliso kunye nokusebenza kokwenyani, kwaye lubangele neengozi zokhuseleko ezingenakulungiseka.
