Background harmonics yakasarudzika scalar huwandu, iyo inowanzo furatirwa nemazhinji mabhizinesi ekugadzira, kunyangwe mushure mekukanganisa kwemuchina nemidziyo, hazvigoneke kuona chiratidzo chekukanganisa.Iye zvino magetsi emagetsi emagetsi ane mitemo yakajeka pamusoro pekuongororwa kwemakambani ekushandisa magetsi.Zvinoenderana nechiyero chenyika: GB/T12326-2008 (simba remhando yemagetsi kushanduka uye flicker), hofisi yemagetsi inotaura kuti kushanduka kwemagetsi kunokonzerwa nemakambani anoshandisa magetsi kunofanirwa kunge kuri kushoma pane THDU (harmonic voltage fluctuation) kukosha kwemuganhu, asi chiyero ichi. haigone kuvimbiswa kumakambani mazhinji anoshandisa ma frequency frequency mitoro, kunyanya iyo harmonic voltage inokonzerwa nemitoro yakadai seyepakati frequency induction furnaces uye inosiyana frequency yekumhanyisa regulators.Zviri nyore kwazvo kudarika mwero nekukasharara!
Harmonic voltage "yakapararira" negetsi remagetsi kune midhiya, uye kunobva harmonic voltage inokamurwa muzvikamu zvitatu:
①Kutakurwa kwemapurojekiti emagetsi asina kukodzera pakupera kwemagetsi emagetsi system;
② The harmonic voltage fluctuation rate inokonzerwa nemidziyo yayo inodarika chiyero;
③Shandisa ma transformer nemamwe makambani, uye harmonic sosi midziyo yemamwe makambani ichakanganiswa;
Njodzi dzakakosha dzekumashure harmonics mugidhi remagetsi dzinonyanya kusanganisira:
1. The automatic control system (frequency conversion speed controller code, PLC) inoshandiswa zvisina kururama uye haina kukodzera;
2. Basa repamusoro-chaiyo michina uye midziyo uye zvidziviriro zvekudzivirira zvine mhirizhonga;
3. Iyo relay yekudzivirira mudziyo inotadza;
4. Iyo inverter mudziyo haigone kushanda;
5. Mhosva yepfupi-yedunhu retatu-phase transformer yakaiswa mukushandurwa kweiyo isina simba ikozvino, nezvimwe.
Iyi njodzi yerudzi ingangokonzeresa kutadza kwemuchina nemidziyo yekambani uye kudonha kwemutsara wekugadzira, kuisa mungozi kushanda kwese uye kuisa mungozi kuchengetedzeka kwekugadzirwa kwemichina nemidziyo;
Mukugadzirwa kwemazuva ano kwemaindasitiri, maturusi emuchina chaiwo, mitsara yekugadzira otomatiki, otomatiki midziyo, uye yemagetsi mudziyo metrology uye yekusimbisa michina inoshandiswa zvakanyanya.Iyo otomatiki yekudzora sisitimu inoita basa rehuropi hwemunhu mumidziyo yese, inoshandiswa kuratidza, yakakwirira-chaiyo metrology verification, yakarongeka maitiro, uye chaiyo Stepper mota, kumhanya chiyero kugadziridzwa uye mamwe azere otomatiki nhanho, izere nekukurumidza kugadzira.Nekudaro, mamwe makambani anowanzo kutadza senge kubviswa kweiyo yemukati magetsi emagetsi dunhu reiyo otomatiki control system, kusvetuka-svetuka kwemakodhi, uye isiriyo PLC mirairo, iyo inokanganisa zvakanyanya kugadzirwa kwakajairwa nekugadzirwa, zvichiita kuti kambani imire kugadzira uye kuderedza mabhenefiti ehupfumi. .Mhosva yemamiriro ezvinhu aya ndeyekuti, kune akawanda ekumashure maharmonics egidhi remagetsi!Makambani mazhinji anowanzo kunetseka nezve kukuvadza kunokonzerwa nekusvibiswa kwezvakatipoteredza zvemichina yavo nemidziyo.Nekuti iyo harmonic ikozvino inodarika mwero, iyo reactive simba rekubhadhara kabati haigone kuchinjika, zvichikonzera yakaderera simba chinhu uye kurangwa nedhipatimendi rakakodzera.Zvino inofanira kusimbiswa kuti kumashure harmonics inofanira kutarisirwa zvakare.Makambani mazhinji akamira kushandisa michina nemidziyo uye akakanganisa maitiro ekugadzira nekuda kwekukuvadza kwemashure maharmonics, izvo zvaunza kurasikirwa kwakakura kwehupfumi kukambani!
Pane musiyano uripo pakati pekumashure harmonics uye corporate harmonic kusvibiswa kwezvakatipoteredza.Midziyo yekudzora yekusvibiswa kweharmonic kunokonzerwa nekambani pachayo ndeyesefa inoshanda iyo munhu wese anoziva nayo.Izvo zvinoenderana nekubhadharira kuchinjika kweiyo harmonic ikozvino uye kudzivirira iyo harmonics kubva pakukanganisa kana kutoparadza iyo kambani michina., kuderedza kusvibiswa kwezvakatipoteredza kune grid yemagetsi;zvisinei, mamwe makambani 'michina nemidziyo haikonzeri harmonics kana kukonzera kushoma harmonics, uye mamwe makambani akatoshongedzerwa zvine musoro nemichina yekusefa, asi michina uye otomatiki kudzora masisitimu achiri anowanzo kukanganiswa neharmonics, zvichikonzera kuvhiringidzika mune otomatiki control system, ablation. zvema transformer madiki, kutadza kwematurusi emuchina chaiwo uye zvimwe zvinowanzoitika!Mamiriro ezvinhu emhando iyi anogona kukonzerwa nekumashure harmonics.Kunyangwe kana sefa inoshanda ikaiswa, hapazove nekufambira mberi.Panguva ino, isu tinofanirwa kusarudza mafirita muripo wemidziyo kuti tiite nemazvo kukanganisa kunokonzerwa neiyo inoshanduka voltage!
Iyo mafirita muripo wemidziyo inotora kushanduka kwemagetsi sechinangwa chekudzora, uye inogona kunyatsoona kugayiwa, kunyura, kudzikisira uye kudzivirirwa kwekudzivirira kwekunze kwemashure harmonics.Kucheneswa kurapa midziyo.Inogona kugadzirisa kushanduka kwakasiyana-siyana kwemagetsi uye kupa yakagadzika switching magetsi emagetsi epamusoro-chaiyo zvigadzirwa zvemagetsi.Iyo yakavakirwa pamisimboti yekutanga yemagineti akateedzana resonance uye microwave sensor kusefa.Iyo ine yakanyanya kugadzikana uye inogona kutariswa semi-chisingaperi switching magetsi.Inonyanya kukodzera kushandiswa munzvimbo dzakanyanyisa dzakasikwa dzakadai sekugadzirwa kwemaindasitiri.Sefa yakasiyana kubva kune general regulated power supply.Iyo haingogone kuburitsa yakagadzikana AC voltage, asi zvakare kubvisa harmonics, surge vadziviriri, uye RF-yakakanganiswa voltages mumagetsi ekuisa.
