Masefa emagetsi anoshandainogona kushandiswa zvakanyanya mumaindasitiri, ekutengeserana uye emasangano ekugovera network, akadai se: magetsi masisitimu, electrolytic plating mabhizinesi, midziyo yekuchenesa mvura, petrochemical enterprises, zvitoro zvikuru uye zvivakwa zvehofisi, mabhizinesi emagetsi emagetsi, airport / port magetsi emagetsi masisitimu, masangano ekurapa. , etc. Maererano nezvinhu zvakasiyana-siyana zvekushandisa, kushandiswa kweinoshanda simba sefaichaita basa mukuona kuvimbika kwemagetsi, kuderedza kupindira, kuvandudza mhando yechigadzirwa, kuwedzera hupenyu hwemidziyo uye kuderedza kukuvara kwemidziyo.
1.Communication industry
Kuti zvizadzise zvinodiwa zvekushanda kwenzvimbo huru dzedata, kugona kweUPS muhurongwa hwekutaurirana nekugovera huri kuwedzera zvakanyanya.Maererano neongororo, iyo huru harmonic sosi yemidziyo yekutaurirana yakaderera-voltage yekugovera sisitimu ndeye UPS, switching magetsi, frequency inoshandura air conditioning uye zvichingodaro.Iyo harmonic yemukati yakakwira, uye iyo displacement simba chinhu cheiyi harmonic sosi michina yakakwira zvakanyanya.Kuburikidza nekushandiswa kweactive sefainogona kuvandudza kugadzikana kwehurongwa hwekutaurirana uye hurongwa hwekugovera simba, kuwedzera hupenyu hwesevhisi yemidziyo yekutaurirana nemidziyo yemagetsi, uye kuita kuti hurongwa hwekugovera simba huenderane nemagadzirirwo emamiriro ezvinhu eharmonic.
2.Semiconductor indasitiri
Iyo 3rd harmonic mune mazhinji semiconductor maindasitiri akakomba, zvakanyanya nekuda kwehuwandu hukuru hweimwe-chikamu chekugadzirisa midziyo inoshandiswa mumabhizinesi.Yechitatu harmonic ndeye zero sequence harmonics, ine hunhu hwekuungana mumutsara usina kwawakarerekera, zvichikonzera kudzvanyirira kwakanyanya pamutsetse usina kwawakarerekera, uye kunyangwe chiitiko chekupisa, icho chine njodzi huru dzakavanzwa mukuchengetedza kugadzirwa.Harmonics inogonawo kukonzera matunhu anotyora rwendo, kunonoka kugadzira nguva.Yechitatu harmonic inoumba kutenderera mu transformer uye inokurumidza kukwegura kweshanduro.Kusvibiswa kwakakomba kweharmonic kuchakanganisa kushanda kwesevhisi uye hupenyu hwemidziyo muhurongwa hwekugovera magetsi.
3.Petrochemical industry
Nekuda kwezvinodiwa zvekugadzirwa, kune huwandu hukuru hwepombi mitoro muindasitiri yepetrochemical, uye mitoro yakawanda yepombi ine inverters.Iko kushandiswa kwefrequency converter kunowedzera zvakanyanya harmonic yemukati musimba rekugovera sisitimu mune petrochemical indasitiri.Mazhinji e inverter rectification link iko kushandiswa kwema 6 pulses kushandura AC kuita DC, saka maharmonics anogadzirwa anonyanya 5, 7, 11 nguva.Njodzi dzayo huru injodzi kumidziyo yemagetsi uye kutsauka mukuyera.Kushandiswa kwesefa inoshanda kunogona kuve mhinduro yakanaka kune iyi dambudziko.
4.Chemical fiber industry
Kuti uvandudze zvakanyanya kunyunguduka, kunatsiridza kunyunguduka kwegirazi, pamwe nekuwedzera hupenyu hwechoto uye kuchengetedza simba, magetsi anonyunguduka ekudziya emidziyo inowanzoshandiswa muindasitiri yemakemikari fiber, uye magetsi anotumirwa zvakananga mutangi regirazi. kupisa nemafuta nerubatsiro rwe electrode.Midziyo iyi inoburitsa huwandu hukuru hwemaharmonics, uye iyo spectrum uye amplitude yematatu-phase harmonics zvakasiyana chaizvo.
5.Steel / yepakati frequency kupisa indasitiri
Yepakati frequency choto, rolling mill, electric arc furnace uye zvimwe zvinoshandiswa zvinowanzoshandiswa muindasitiri yesimbi zvichave nemhedzisiro yakakura pamhando yesimba regidhi remagetsi, kuitira kuti capacitor compensation cabinet overload protection action is often, the transformer and the power. tambo yekupisa kupisa kwakakomba, fuse inogara ichivhuvhuta, uye inokonzeresa kudonha kwevoltage, flicker.
6.Indasitiri yekugadzira motokari
Welding muchina chinhu chakakosha muindasitiri yekugadzira mota, nekuti muchina welding une hunhu hwekusarongeka, nekukurumidza uye nekukanganisa, zvekuti huwandu hukuru hwemichina yewelding inokonzeresa matambudziko makuru emhando yemagetsi, zvichikonzera kusagadzikana kwemhando yewelding, marobhoti ane yakakwirira. dhigirii re automation haigone kushanda nekuda kwekusagadzikana kwemagetsi, reactive simba rekubhadhara system haigone kushandiswa zvakajairwa.
7.Harmonic control yeDC mota
Nzvimbo dzendege dzeDC dzakakura dzinoda kushandura AC kuenda kuDC kuburikidza nemidziyo yekugadziridza kutanga, nekuti huwandu hwezvirongwa zvakadaro hwakakura, saka kune kusvibiswa kwakakomba kudivi reAC, zvichikonzera kukanganisa kwemagetsi, uye tsaona dzakakomba.
8.Kushandisa mitsara yekugadzira michina uye midziyo yakarurama
Mune otomatiki yekugadzira mutsara uye chaiyo midziyo, harmonics ichakanganisa kushandiswa kwayo kwakajairika, kuitira kuti hungwaru kutonga system, PLC system, nezvimwe, kukundikana.
9.Hospital system
Zvipatara zvine zvinodiwa zvakanyanya pakuenderera uye kuvimbika kwemagetsi.Iyo otomatiki magetsi ekudzoreredza nguva yeClass 0 nzvimbo ndeye T≤15S, iyo otomatiki magetsi ekugadzirisa emagetsi nguva yeClass 1 nzvimbo ndeye 0.5S≤T≤15S, iyo otomatiki magetsi ekugadzirisa nguva yekirasi 2 nzvimbo ndeye T≤0.5S, uye iyo yakazara harmonic kukanganisa mwero wevoltage THDu ndeye ≤3%.Michina yeX-ray, michina yeCT, uye nyukireya magineti resonance zvese zvinoremerwa zvine zvakanyanyisa kuwirirana zvemukati.
10.Theatre/Gymnasium
Thyristor dimming system, hombe ye LED michina uye zvichingodaro ndeye harmonic masosi, mukuita basa ichaburitsa nhamba huru yechitatu harmonic, kwete chete kukonzera simba rekugovera sisitimu yesimba remagetsi kusashanda, asiwo kukonzera light strobe, kutaurirana, cable TV. uye mamwe asina simba emagetsi edunhu ruzha, uye kunyange kuburitsa kukundikana.
