Zosefera mphamvu yogwiraangagwiritsidwe ntchito kwambiri m'mafakitale, malonda ndi mabungwe kugawa maukonde, monga: machitidwe magetsi, electrolytic plating mabizinesi, zipangizo madzi mankhwala, mabizinesi petrochemical, masitolo akuluakulu ndi nyumba maofesi, mwatsatanetsatane mabizinesi zamagetsi, ndege/doko magetsi magetsi, mabungwe azachipatala , etc. Malinga ndi zinthu zosiyanasiyana ntchito, ntchito yafyuluta yamphamvu yogwiraidzatenga gawo pakuwonetsetsa kudalirika kwamagetsi, kuchepetsa kusokoneza, kukonza zinthu zabwino, kuwonjezera moyo wa zida ndi kuchepetsa kuwonongeka kwa zida.
1.Kulumikizana ndi makampani
Pofuna kukwaniritsa zofunikira zogwirira ntchito za malo akuluakulu a deta, mphamvu ya UPS mu njira yolumikizirana ndi yogawa ikuwonjezeka kwambiri.Malinga ndi kafukufukuyu, zida zazikulu zolumikizirana zotsika-voltage zolumikizirana ndi UPS, magetsi osinthira, ma frequency conversion air conditioning ndi zina zotero.Zomwe zili ndi ma harmonic ndizokwera kwambiri, ndipo mphamvu yosuntha ya zida zamtunduwu ndizokwera kwambiri.Pogwiritsa ntchitofyuluta yogwiraikhoza kupititsa patsogolo kukhazikika kwa njira yolumikizirana ndi njira yogawa mphamvu, kuwonjezera moyo wautumiki wa zida zoyankhulirana ndi zida zamagetsi, ndikupanga dongosolo logawa mphamvu kuti likhale logwirizana ndi mapangidwe achilengedwe a harmonic.
Makampani a 2.Semiconductor
The 3rd harmonic m'mafakitale ambiri a semiconductor ndizovuta kwambiri, makamaka chifukwa cha kuchuluka kwa zida zowongolera gawo limodzi zomwe zimagwiritsidwa ntchito m'mabizinesi.Harmonic yachitatu ndi ya zero sequence harmonics, yomwe ili ndi mawonekedwe osonkhanitsidwa mumzere wosalowerera ndale, zomwe zimapangitsa kuti pakhale kukakamizidwa kwambiri pamzere wosalowerera ndale, komanso chodabwitsa choyaka moto, chomwe chimakhala ndi zoopsa zobisika pachitetezo chopanga.Ma Harmonics amathanso kupangitsa kuti ophwanya madera aziyenda, kuchedwetsa nthawi yopanga.Haronic yachitatu imapanga kufalikira mu thiransifoma ndikufulumizitsa ukalamba wa thiransifoma.Kuipitsa kwakukulu kwa harmonic kudzakhudza momwe ntchitoyo ikuyendera komanso moyo wa zida zomwe zili mu dongosolo logawa mphamvu.
3. Petrochemical industry
Chifukwa cha zofunikira pakupanga, pali kuchuluka kwa mapampu mumakampani a petrochemical, ndipo katundu wambiri wamapampu amakhala ndi ma inverters.Kugwiritsa ntchito ma frequency converter kumawonjezera kwambiri zomwe zili mu harmonic mu dongosolo logawa mphamvu mumakampani a petrochemical.Maulalo ambiri osinthira ma inverter ndikugwiritsa ntchito ma pulses 6 kuti asinthe AC kukhala DC, kotero ma harmonics omwe amapangidwa amakhala makamaka 5, 7, 11.Zowopsa zake zazikulu ndizowopsa kwa zida zamagetsi ndi kupatuka kwa kuyeza.Kugwiritsa ntchito fyuluta yogwira kungakhale njira yabwino yothetsera vutoli.
4.Chemical fiber industry
Pofuna kukonza kwambiri kusungunuka kwa magalasi, kusungunuka kwa galasi, komanso kukulitsa moyo wa ng'anjo ndikupulumutsa mphamvu, zida zotenthetsera zamagetsi zimagwiritsidwa ntchito kwambiri pamakampani opanga ma fiber, ndipo magetsi amatumizidwa mwachindunji mu uvuni wagalasi. kutenthedwa ndi mafuta mothandizidwa ndi ma electrode.Zida izi zidzatulutsa ma harmonics ambiri, ndipo mawonekedwe ndi matalikidwe a ma harmonics a magawo atatu ndizosiyana kwambiri.
5.Steel / medium frequency heat industry
ng'anjo yapakatikati pafupipafupi, mphero yopukutira, ng'anjo yamagetsi yamagetsi ndi zida zina zomwe zimagwiritsidwa ntchito m'mafakitale zitsulo zidzakhudza kwambiri mphamvu ya gululi mphamvu, kotero kuti capacitor chipukuta misozi nduna zimamuchulukira chitetezo kanthu pafupipafupi, thiransifoma ndi mphamvu. Kutentha kwa mzere wamagetsi ndikowopsa, fusesiyo imawomberedwa pafupipafupi, ndipo ngakhale kuchititsa kutsika kwamagetsi, kufota.
6. Makampani opanga magalimoto
Makina owotcherera ndi chida chofunikira kwambiri pamakampani opanga magalimoto, chifukwa makina owotcherera ali ndi mawonekedwe amwachisawawa, mwachangu komanso mwamphamvu, kotero kuti makina ambiri owotcherera amayambitsa zovuta zazikulu zamtundu wamagetsi, zomwe zimabweretsa kusakhazikika kowotcherera, maloboti okhala ndi zida zambiri. digiri ya zochita zokha sangathe kugwira ntchito chifukwa voteji kusakhazikika, zotakasuka mphamvu chipukuta misozi dongosolo sangathe ntchito bwinobwino.
7.Harmonic control ya DC motor
Ma eyapoti akuluakulu a DC amayenera kusinthira AC kukhala DC kudzera pa zida zowongolera kaye, chifukwa kuchuluka kwa mapulojekiti otere ndiakuluakulu, ndiye kuti mbali ya AC pali kuyipitsidwa kwakukulu, zomwe zimapangitsa kusokonekera kwa magetsi, komanso ngozi zazikulu.
8.Kugwiritsa ntchito mizere yopangira makina ndi zida zolondola
Mu mzere wopanga zodziwikiratu ndi zida zolondola, ma harmonics angakhudze ntchito yake yanthawi zonse, kuti dongosolo lanzeru lowongolera, dongosolo la PLC, ndi zina zambiri, kulephera.
9.Chipatala
Zipatala zili ndi zofunika kwambiri pa kupitiriza ndi kudalirika kwa magetsi.Nthawi yobwezeretsa magetsi a malo a Class 0 ndi T≤15S, nthawi yobwezeretsa mphamvu ya malo a Class 1 ndi 0.5S≤T≤15S, nthawi yobwezeretsa mphamvu ya malo a kalasi 2 ndi T≤0.5S, ndi chiwopsezo chonse chosokonekera chamagetsi a THDu ndi ≤3%.Makina a X-ray, makina a CT, ndi mphamvu ya maginito ya nyukiliya zonse ndizodzaza ndi zinthu zambiri zolumikizana.
10.Theatre/Gymnasium
Thyristor dimming dongosolo, lalikulu LED zida ndi zina zotero ndi magwero harmonic, mu ndondomeko ntchito adzabala chiwerengero chachikulu cha lachitatu harmonic, osati chifukwa mphamvu kugawa dongosolo la mphamvu zida inefficiency, komanso chifukwa kuwala strobe, kulankhulana, chingwe TV. ndi zina ofooka magetsi dera phokoso, ndipo ngakhale kutulutsa kulephera.
