Ma harmonics akumbuyo ndi mtundu wapadera wa scalar, womwe nthawi zambiri umanyalanyazidwa ndi mabizinesi ambiri opanga, ngakhale atakhudzidwa ndi makina ndi zida, ndizosatheka kudziwa chizindikiro chosokoneza.Tsopano gawo lamagetsi lamagetsi lili ndi malamulo omveka bwino pakuwunika kwamakampani omwe amagwiritsa ntchito mphamvu.Malinga ndi muyezo wapadziko lonse: GB/T12326-2008 (kusinthasintha kwamphamvu kwamagetsi ndi kusinthasintha), bungwe loyang'anira magetsi likunena kuti kusinthasintha kwamagetsi opangidwa ndi makampani ogwiritsira ntchito magetsi kuyenera kukhala kochepa kuposa THDU (harmonic voltage fluctuation) koma muyezo uwu. sizingatsimikizidwe kumakampani ambiri omwe amagwiritsa ntchito ma frequency osinthika, makamaka ma voltages obwera chifukwa cha katundu monga ng'anjo zapakatikati komanso zowongolera ma frequency frequency.Ndikosavuta kupitilira muyezo ndi kuuma!
Harmonic voliyumu ndi "kufalikira" ndi gululi mphamvu kwa atolankhani, ndipo gwero la voteji harmonic amagawidwa m'magulu atatu:
①Kuyendetsa ma projekiti osayenerera amagetsi kumapeto kwamagetsi;
② Kusinthasintha kwamphamvu kwamagetsi komwe kumachitika chifukwa cha zida zake kumaposa muyezo;
③Gwiritsani ntchito zosinthira ndi makampani ena, ndipo zida zamakampani ena zidzakhudzidwa;
Zowopsa zazikulu za ma harmonics akumbuyo mu gridi yamagetsi makamaka zimaphatikizapo:
1. Dongosolo lodzilamulira lokha (kodi yowongolera liwiro la kutembenuka kwanthawi yayitali, PLC) imayendetsedwa molakwika komanso yosayenera;
2. Ntchito yamakina olondola kwambiri ndi zida ndi zida zodzitetezera ndizosokoneza;
3. Chipangizo chachitetezo cha relay chimalephera;
4. Chipangizo cha inverter sichingagwire ntchito;
5. Kulakwitsa kwafupipafupi kwa thiransifoma ya magawo atatu omwe amaikidwa mu kutembenuka kwamakono ofooka, ndi zina zotero.
Zowopsa zamtunduwu zitha kuchititsa kulephera kwa makina ndi zida zamakampani komanso kugwa kwa mzere wopanga, kuyika pachiwopsezo chakuchita bwino komanso kuyika pachiwopsezo chitetezo cha makina ndi zida;
Pakupanga mafakitale amakono, zida zamakina olondola, mizere yopangira zokha, zida zamagetsi, ndi zida zamagetsi zamagetsi ndi zida zotsimikizira zimagwiritsidwa ntchito kwambiri.Dongosolo lodzilamulira lodziwikiratu limagwira ntchito yaubongo wamunthu pazida zonse, zomwe zimagwiritsidwa ntchito powonetsera, kutsimikizira kwapamwamba kwambiri kwa metrology, njira zolumikizirana, ndi injini yolondola ya Stepper, kusintha kwa liwiro ndi magawo ena odziwikiratu, kupanga kofulumira.Komabe, makampani ena nthawi zambiri amakhala ndi zolephera monga kuchotsedwa kwamagetsi amkati amagetsi owongolera okha, kulumpha kwachisawawa, ndi malamulo olakwika a PLC, omwe amakhudza kwambiri kupanga ndi kupanga kwanthawi zonse, kupangitsa kampaniyo kuyimitsa kupanga ndikuchepetsa phindu lazachuma. .Choyambitsa izi ndikuti, pali zambiri zakumbuyo za gridi yamagetsi!Makampani ambiri amakhala ndi nkhawa chifukwa cha kuwonongeka kwa chilengedwe kwa makina awo ndi zida zawo.Chifukwa mphamvu ya harmonic imaposa muyezo, kabati yolipirira mphamvu yogwira ntchito siyingasinthidwe, zomwe zimapangitsa kuti pakhale mphamvu zochepa komanso kulangidwa ndi dipatimenti yoyenera.Tsopano ziyenera kutsindika kuti ma harmonics akumbuyo ayenera kusamalidwanso.Makampani ambiri asiya kugwiritsa ntchito makina ndi zida ndikusokoneza njira zopangira chifukwa chakuwonongeka kwa ma harmonics akumbuyo, zomwe zabweretsa kuwonongeka kwakukulu kwachuma ku kampani!
Pali kusiyana pakati pa ma harmonics akumbuyo ndi kuwonongeka kwa chilengedwe chamakampani.Zida zowongolera zowonongeka za harmonic zomwe zimayambitsidwa ndi kampaniyo yokha ndi fyuluta yogwira yomwe aliyense amadziwa.Zimatengera kubweza kusinthasintha kwa ma harmonic panopa ndikuletsa ma harmonics kuti asakhudze kapena kuwononga zida za kampaniyo., kuchepetsa kuwonongeka kwa chilengedwe ku gridi yamagetsi;Komabe, makina ndi zida zamakampani ena sizimayambitsa ma harmonics kapena zimapangitsa kuti pakhale ma harmonics ochepa, ndipo makampani ena ali ndi zida zosefera, koma makina ndi machitidwe owongolera okha nthawi zambiri amakhudzidwa ndi ma harmonics, zomwe zimayambitsa chisokonezo mu dongosolo lowongolera, ablation. zosinthira zazing'ono, kulephera kwa zida zamakina olondola ndi zolakwika zina wamba!Mtundu woterewu ukhoza kuyambitsidwa ndi ma harmonics akumbuyo.Ngakhale fyuluta yogwira itayikidwa, sipadzakhala kupita patsogolo.Pakadali pano, tiyenera kusankha zida zolipirira zosefera kuti tithane ndi zovuta zomwe zimachitika chifukwa chamagetsi osinthika!
Zida zolipirira zosefera zimatenga kusinthasintha kwamagetsi ngati cholinga chowongolera, ndipo zimatha kuzindikira kugaya, kuyamwa, kuchepetsa komanso kudzipatula kwa ma harmonics akunja.Zida zochizira zoyeretsera.Imatha kukonza kusinthasintha kwamagetsi osiyanasiyana ndikupereka mphamvu zosinthira zokhazikika pamagetsi olondola kwambiri.Zimatengera mfundo zazikulu za maginito mndandanda wa resonance ndi kusefa kachipangizo ka microwave.Ili ndi kukhazikika kwapamwamba kwambiri ndipo imatha kuwonedwa ngati mphamvu yosinthira yokhazikika.Ndizoyenera kwambiri kuti zigwiritsidwe ntchito m'malo owopsa achilengedwe monga kupanga mafakitale.Fyulutayi ndi yosiyana ndi magetsi omwe amayendera.Sizingangotulutsa magetsi okhazikika a AC, komanso kuchotsa ma harmonics, oteteza ma surge, ndi ma voltages okhudzidwa ndi RF mumagetsi olowera.
