I-harmonics yemvelaphi yinto ekhethekileyo ye-scalar quantity, edla ngokungahoywa ngamashishini amaninzi okuvelisa, nasemva kwempembelelo yomatshini kunye nezixhobo, akunakwenzeka ukumisela umqondiso wokuphazamiseka.Ngoku iyunithi yenkqubo yokubonelela ngombane inemimiselo ecacileyo malunga novavanyo lweenkampani zokusetyenziswa kwamandla.Ngokomgangatho wesizwe: I-GB/T12326-2008 (ukuguquguquka komgangatho wamandla ombane kunye ne-flicker), i-ofisi yobonelelo lwamandla ichaza ukuba ukuguquguquka kwamandla ombane okwenziwa ziinkampani ezisebenzisa amandla kufuneka kube ngaphantsi kwe-THDU (ukuguquguquka kombane we-harmonic) ixabiso lomda, kodwa lo mgangatho ayinakuqinisekiswa kwiinkampani ezininzi ezisebenzisa imithwalo eguquguqukayo yamaza, ngakumbi amandla ombane we-harmonic obangelwa yimithwalo efana ne-intermediate frequency induction furnaces kunye nezilawuli zesantya esiguqukayo.Kulula kakhulu ukugqitha umgangatho kunye noburhabaxa!
Umbane weHarmonic "usasazwa" yigridi yamandla kumajelo eendaba, kwaye umthombo wamandla ombane we-harmonic wahlulwe kakhulu ngokweendidi ezintathu:
①Ukuthuthwa kweeprojekthi zamandla angafanelekanga ekupheleni kwenkqubo yobonelelo lombane;
② Umyinge wokuguquguquka kwamandla ombane we-harmonic obangelwa sisixhobo sawo udlula umgangatho;
③Sebenzisa iziguquli kunye nezinye iinkampani, kwaye izixhobo zomthombo weharmonic zezinye iinkampani ziyakuchaphazeleka;
Iingozi eziphambili zeharmonics yangasemva kwigridi yamandla ikakhulu ziquka:
1. Inkqubo yokulawula ngokuzenzekelayo (ikhowudi yokulawula isantya sokuguqula i-frequency, i-PLC) ayisebenzi kakuhle kwaye ayifanelekanga;
2. Umsebenzi womatshini wokuchaneka okuphezulu kunye nezixhobo kunye nezixhobo zokukhusela ziyisiphithiphithi;
3. Isixhobo sokukhusela i-relay siyasilela;
4. Isixhobo se-inverter asinakusebenza;
5. Iphutha le-short-circuit ye-transformer yesigaba sesithathu efakwe kwi-conversion of current weak, njl.
Olu hlobo lwengozi lunokubangela ukusilela koomatshini kunye nezixhobo zenkampani kunye nokuwa komgca wemveliso, kubeka emngciphekweni ukusebenza kakuhle kunye nokubeka emngciphekweni ukhuseleko lokuvelisa koomatshini kunye nezixhobo;
Kwimveliso yanamhlanje yemizi-mveliso, izixhobo zoomatshini ezichanekileyo, imigca yokuvelisa ngokuzenzekelayo, izixhobo ezizisebenzelayo, kunye nesixhobo sombane se-metrology kunye nezixhobo zokuqinisekisa zisetyenziswa ngokubanzi.Inkqubo yokulawula ngokuzenzekelayo idlala indima yobuchopho bomntu kuzo zonke izixhobo, ezisetyenziselwa umboniso, ukuqinisekiswa kwe-metrology echanekileyo, iinkqubo ezilungelelanisiweyo, kunye ne-Stepper motor echanekileyo, ukulungiswa komlinganiselo wesantya kunye nezinye izigaba ezizenzekelayo ngokupheleleyo, ukugqiba ukuveliswa ngokukhawuleza.Nangona kunjalo, ezinye iinkampani zihlala zinokusilela okunje ngokukhutshwa kwesekethe yonikezelo lwamandla lwangaphakathi lwenkqubo yolawulo oluzenzekelayo, ukutsiba okungacwangciswanga kweekhowudi, kunye nemiyalelo ye-PLC engachanekanga, echaphazela kakhulu imveliso eqhelekileyo kunye nemveliso, ebangela ukuba inkampani iyeke imveliso kwaye inciphise izibonelelo zoqoqosho. .Unobangela wale meko kukuba, kukho ezininzi ii-harmonics zemvelaphi yegridi yamandla!Iinkampani ezininzi zihlala zixhalabile ngomonakalo obangelwa kukungcoliseka kwendalo okuhambelanayo koomatshini kunye nezixhobo zabo.Ngenxa yokuba i-harmonic current idlula umgangatho, ikhabhinethi yembuyekezo yamandla asebenzayo ayinakutshintshwa, okukhokelela kumandla aphantsi kwaye ijeziswe lisebe elifanelekileyo.Ngoku kufuneka kugxininiswe ukuba i-harmonics yangasemva kufuneka ithathelwe ingqalelo ngokunjalo.Iinkampani ezininzi ziye zayeka ukusebenzisa oomatshini kunye nezixhobo kunye neenkqubo zokuvelisa ngenxa yokulimala kwe-harmonics yangasemva, okuzise ilahleko enkulu yophuhliso loqoqosho kwinkampani!
Kukho umahluko phakathi kwe-harmonics yangasemva kunye nongcoliseko lwendalo esingqongileyo.Izixhobo zokulawula ungcoliseko lwe-harmonic olubangelwa yinkampani ngokwayo sisihluzo esisebenzayo esiqhelekileyo wonke umntu.Ngokusisiseko kuxhomekeke kwimbuyekezo yokuguquguquka kwe-harmonic yangoku kunye nokuthintela i-harmonics ekuchaphazeleni okanye nasekutshabalaliseni izixhobo zenkampani., ukunciphisa ungcoliseko lokusingqongileyo kwigridi yamandla;nangona kunjalo, oomatshini kunye nezixhobo ezithile zeenkampani azibangeli i-harmonics okanye zibangele i-harmonics engaphantsi, kwaye ezinye iinkampani sele zixhotyiswe ngokufanelekileyo ngezixhobo zokucoca, kodwa oomatshini kunye neenkqubo zokulawula ezizenzekelayo zihlala zichatshazelwa yi-harmonics, ebangela ukudideka kwinkqubo yokulawula ngokuzenzekelayo, ukuchithwa. yeziguquli ezincinci, ukungaphumeleli kwezixhobo zomatshini ezichanekileyo kunye nezinye iimpazamo eziqhelekileyo!Olu hlobo lwemeko lunokubangelwa yi-harmonics yangasemva.Nokuba isihluzo esisebenzayo sifakiwe, akuyi kubakho nkqubela phambili.Ngeli xesha, kufuneka sikhethe izixhobo zembuyekezo yesihluzi ukuze sijongane ngokufanelekileyo nefuthe elibangelwa ngumbane oguquguqukayo!
Isixhobo sembuyekezo yesihluzi sithatha ukuguquguquka kombane njengenjongo yolawulo, kwaye sinokuqonda kakuhle ukugaya, ukufunxa, ukunciphisa kunye nokukhuselwa kwasodwa kwe-harmonics yangaphandle yangasemva.Izixhobo zonyango zokucoca.Iyakwazi ukulungisa ukuguquguquka okwahlukeneyo kwamandla ombane kwaye ibonelele ngombane otshintshileyo ozinzileyo kwiimveliso zombane ezichanekileyo.Isekwe kwimigaqo esisiseko yochungechunge lwemagnethi resonance kunye nokucoca isivamvo se-microwave.Inozinzo oluphezulu kakhulu kwaye inokuthathwa njengonikezelo lombane olutshintshayo olungenasiphelo.Ngokukodwa ifanelekile kwizicelo kwiindawo zendalo ezigqithisileyo ezifana nokuveliswa kwemveliso.Isihluzi sahlukile kunikezelo lwamandla olulawulwa ngokubanzi.Ayinakukhupha kuphela i-voltage ye-AC ezinzileyo, kodwa iphinde isuse i-harmonics, izikhuseli zotyando, kunye nombane ochatshazelwe yi-RF kumbane wegalelo.
