Ama-harmonics angemuva ayinani elihlukile le-scalar, elivame ukushaywa indiva amabhizinisi amaningi okukhiqiza, ngisho nangemva komthelela wemishini nemishini, akunakwenzeka ukucacisa isignali yokuphazamiseka.Manje uphiko lwesistimu yokuhlinzeka ngogesi lunemithethonqubo ecacile yokuhlolwa kwezinkampani ezisebenzisa amandla kagesi.Ngokwendinganiso kazwelonke: I-GB/T12326-2008 (ukuguquguquka nokucwayiza kwamandla kagesi wekhwalithi yamandla), isikhungo sokuphakelwa kukagesi sibeka ukuthi ukushintshashintsha kwamandla kagesi okukhiqizwa izinkampani ezisebenzisa amandla kumele kube ngaphansi kwe-THDU (ukuguquguquka kwamandla kagesi okuhambisanayo) kodwa leli zinga. ayikwazi ukuqinisekiswa ezinkampanini eziningi ezisebenzisa imithwalo yefrikhwensi eguquguqukayo, ikakhulukazi i-harmonic voltage ebangelwa imithwalo efana neziko lokungeniswa kwamafrikhwensi amaphakathi kanye nezilawuli zesivinini esishintshashintshayo.Kulula kakhulu ukweqa indinganiso ngobulukhuni!
I-Harmonic voltage "isatshalaliswa" yigridi yamandla kwabezindaba, futhi umthombo we-harmonic voltage uhlukaniswe ikakhulukazi izigaba ezintathu:
①Ukuthuthwa kwamaphrojekthi kagesi angafaneleki ekupheleni kwesistimu yokunikezwa kwamandla;
② Izinga lokuguquguquka kwamandla kagesi we-harmonic okubangelwa amathuluzi ayo lidlula izinga;
③Sebenzisa ama-transformer nezinye izinkampani, futhi imishini yomthombo we-harmonic yezinye izinkampani izothinteka;
Izingozi eziyinhloko zama-harmonics angemuva kugridi yamandla ikakhulukazi zihlanganisa:
1. Isistimu yokulawula okuzenzakalelayo (ikhodi yesilawuli sesivinini sokuguqulwa kwemvamisa, i-PLC) ayisebenzi kahle futhi ayifanelekile;
2. Umsebenzi wemishini enembayo ephezulu kanye nemishini nemishini yokuzivikela unesiphithiphithi;
3. Idivayisi yokuvikela i-relay iyahluleka;
4. Idivayisi ye-inverter ayikwazi ukusebenza;
5. Iphutha le-short-circuit ye-transformer yesigaba ezintathu efakwe ekuguqulweni kwamandla abuthakathaka, njll.
Lolu hlobo lwengozi lungase lubangele ukwehluleka kwemishini nemishini yenkampani kanye nokuwa kolayini wokukhiqiza, kubeke engozini ukusebenza kahle okuphelele futhi kubeke engozini ukuphepha kokukhiqizwa kwemishini nezinto zokusebenza;
Emkhiqizweni wesimanje wezimboni, amathuluzi omshini wokunemba, imigqa yokukhiqiza ezenzakalelayo, okokusebenza okuzenzakalelayo, kanye ne-electronic device metrology kanye nemishini yokuqinisekisa kusetshenziswa kakhulu.Isistimu yokulawula okuzenzakalelayo idlala indima yobuchopho bomuntu kukho konke okokusebenza, okusetshenziselwa ukuboniswa, ukuqinisekiswa kwe-metrology enembayo ephezulu, izinqubo ezididiyelwe, kanye ne-Stepper motor enembile, ukulungiswa kwesilinganiso sesivinini kanye nezinye izigaba ezizenzakalelayo ngokugcwele, ukukhiqiza okuphelele okuphelele.Kodwa-ke, ezinye izinkampani zivame ukuba nokwehluleka okufana nokwehliswa kwesekethe yokuphakelwa kwamandla yangaphakathi yesistimu yokulawula okuzenzakalelayo, ukweqa okungahleliwe kwamakhodi, nemiyalo engalungile ye-PLC, okuthinta kakhulu ukukhiqizwa nokukhiqiza okuvamile, okubangela inkampani ukuthi imise ukukhiqiza futhi yehlise izinzuzo zezomnotho. .Icala elingemuva kwalesi simo ukuthi, maningi ama-harmonics angemuva wegridi yamandla!Izinkampani eziningi zivame ukukhathazeka ngokulimala okubangelwa ukungcoliswa kwemvelo kwemishini nemishini yazo.Ngenxa yokuthi i-harmonic current idlula izinga, ikhabhinethi yesinxephezelo samandla asebenzayo ayikwazi ukushintshwa, okuholela kusici samandla aphansi futhi ijeziswe umnyango ofanele.Manje kufanele kugcizelelwe ukuthi ama-harmonics angemuva kufanele anakekelwe futhi.Izinkampani eziningi ziye zayeka ukusebenzisa imishini nemishini futhi zaphazamisa izinqubo zokukhiqiza ngenxa yokulimala kwama-harmonics angemuva, okulethe ukulahlekelwa okukhulu kokuthuthukiswa komnotho enkampanini!
Kunomehluko phakathi kwama-harmonics angemuva kanye nokungcoliswa kwemvelo kwe-harmonic yebhizinisi.Imishini yokulawula yokungcoliswa kwe-harmonic okubangelwa inkampani ngokwayo iyisihlungi esisebenzayo wonke umuntu asijwayele.Ngokuyisisekelo kuncike ekunxephezeleni ukuguquguquka kwe-harmonic yamanje nokuvimbela ama-harmonics ukuthi athinte noma acekele phansi imishini yenkampani uqobo., ukunciphisa ukungcoliswa kwemvelo kugridi kagesi;noma kunjalo, imishini nemishini yezinkampani ezithile azibangeli i-harmonics noma zibangele ama-harmonics amancane, futhi ezinye izinkampani sezivele zinemishini yokuhlunga ngokufanelekile, kodwa imishini nezinhlelo zokulawula okuzenzakalelayo zisalokhu zithinteka yi-harmonics, okubangela ukudideka ohlelweni lokulawula okuzenzakalelayo, ukukhishwa kwe-ablation. yama-transformer amancane, ukwehluleka kwamathuluzi omshini wokunemba kanye namanye amaphutha ajwayelekile!Lolu hlobo lwesimo lungase ludalwe ukuhambisana kwengemuva.Ngisho noma isihlungi esisebenzayo sifakiwe, ngeke kube khona ukuqhubeka.Ngalesi sikhathi, kufanele sikhethe izisetshenziswa zesinxephezelo zokuhlunga ukuze sibhekane ngokuphumelelayo nomthelela obangelwa i-voltage eguquguqukayo!
Imishini yesinxephezelo yesihlungi ithatha ukushintshashintsha kwe-voltage njengomgomo wokulawula, futhi ingabona kahle ukugayeka kokudla, ukumuncwa, ukuncipha kanye nokuvikelwa kokuhlukaniswa kwama-harmonics angaphandle angemuva.Imishini yokwelapha yokuhlanza.Ingakwazi ukulungisa ukushintshashintsha kwamandla kagesi okuhlukahlukene futhi inikeze amandla okushintsha okuzinzile emikhiqizweni ye-elekthronikhi enembayo.Isekelwe ezimisweni eziyisisekelo zochungechunge lukazibuthe resonance kanye nokuhlunga kwenzwa ye-microwave.Inozinzo oluphakeme kakhulu futhi ingathathwa njengokunikezwa kwamandla okushintshwa okuhlala unomphela.Ifaneleka ngokukhethekile izinhlelo zokusebenza ezindaweni zemvelo ezeqisayo ezifana nokukhiqizwa kwezimboni.Isihlungi sihlukile kugesi olawulwayo ojwayelekile.Ayikwazi kuphela ukukhipha i-voltage ye-AC ezinzile, kodwa futhi isuse ama-harmonics, izivikeli zokuhlinza, nama-voltage athinteke yi-RF ku-voltage yokufaka.
