Iyini I-Harmonics Yamanje?

Njengoba izinto eziningi ze-elekthronikhi ezisetshenziswa namuhla ziye zanda kakhulu, isizathu esiyinhloko sokwakheka kwama-harmonics kubonakala sengathi lesi sixuku samadivayisi.Ngamanye amazwi, uma sizobuza ukuthi kungani i-harmonics yenzeka, isizathu esiyisisekelo esilele lapha impilo yesimanje ngokwayo.Ngaphezu kwalokho, ukusetshenziswa kwamasu esimanje okuguqula amandla ngaleyo nombolo ekhulayo yamadivayisi nakho kudala i-harmonic current.

Nokho, lokhu akwenzeki ngaso sonke isikhathi njengoba amandla kagesi e-DC aya ngokuya ethandwa.Ngisho nokusetshenziswa kabanzi kokukhanyisa kwe-LED, ikakhulukazi ezindaweni zomphakathi nezakhiwo, kubangela i-harmonic current.Uma siqoqa konke lokhu, singachaza i-harmonic yamanje kanje: amagagasi e-sinusoidal ngaphandle kwegagasi elivamile eliyisisekelo eliphazamisa i-voltage.Amagagasi e-Sinusoidal abhekwa njenge-harmonic yamanje futhi inombolo enkulu yamadivayisi ohlelweni ingaba isizathu esiyinhloko salokhu.

Ngamanye amazwi, ukwakheka kwezingxenye ze-harmonic ohlelweni akusona isimo esifiselekayo ohlelweni lukagesi.Imithwalo ehlukahlukene ingabangela lokhu, kodwa idinga ukulinganiswa ihlolwe futhi ivinjwe.Ngenye incazelo, i-harmonic yigama lobuchwepheshe elinikezwe ukuwohloka kukagesi ngendlela yezono.Namuhla lesi simo singenzeka kalula ezinhlelweni ezingaphansi komthwalo omningi, okungukuthi, kuvamile.

Kulokhu, sekubalulekile ukuqaphela futhi ukuvimbele.Isibonelo, amakhadi e-elekthronikhi, izinjini kanye nabashayeli, izinsiza zamandla ezingaphazamiseki, izibani ze-fluorescent zingase zibe ziningi kakhulu ohlelweni.Ngokufanayo, ngendlela elula, ama-harmonics akhiwa lapho inani elikhulu lamakhompiyutha kanye nemishini esikhulume ngayo ngenhla ihlangana ndawonye.Kuyadingeka ukuthatha izinyathelo zokuphepha zokuvikela ukwakheka kwe-harmonic futhi uvikeleke ekulimaleni kwayo.Uma kungenjalo, ama-transformer athola ukushisa ngokweqile, amadivaysi angase alimale futhi i-voltage yamapayipi izowohloka kakhulu.Ngokubonakala kwezimpawu ezinjalo ezimweni ezifanayo, ukugcwala ngokweqile kudala izinto ezinkulu eziyingozi futhi izinyathelo zokuphepha zidingeka kakhulu.

Ukusetshenziswa kweNoker Electricisihlungi samandla asebenzayo, ingakwazi ukuhlunga i-harmonic current ohlelweni, ithuthukise isici samandla wesistimu, futhi ingalungiselelwa uhlelo olungalingani lwezigaba ezintathu, iyithuluzi elifaneleka kakhulu lokuthuthukisa ikhwalithi yokunikezwa kwamandla.
