Okwangoku, obona buchule bolawulo lwe-harmonic kwimarike luluhlu lwe-APF olusezantsi lwevoltage esebenzayo ephuhliswe kwaye yenziwe nguHongyan Electric.Eli licandelo lamandla e-elektroniki elisekwe kuhlolo lwangoku kunye nethekhinoloji yentshayelelo yangoku.Icandelo langoku le-harmonic eliza kuhlawulwa lifunyenwe ngokuhambelana nomthwalo wokubeka iliso okhoyo ngoku.Ngokulawula i-trigger ye-IGBT, iteknoloji yokuguqula i-pulse ububanzi be-modulation isetyenziselwa ukwazisa i-harmonics, amacandelo asebenzayo kunye nemisinga kwicala elichaseneyo nenkqubo yokusabalalisa amandla ukuphumeza umphumo wokuphelisa i-harmonics.Isihluzo esisebenzayo sinokudlula malunga nama-95%, ngaloo ndlela siphucula ukhuseleko kunye nokuthembeka kwenkqubo yonikezelo lwamandla, kunye nokufezekisa injongo yokhuseleko lokusingqongileyo, ukonga amandla kunye nokuphucula ukusebenza kakuhle.
Ukuqwalaselwa kwemigaqo yenkampani esebenzayo ngumqhubi ophambili kwiinkampani ukuphumeza ulawulo lwe-harmonic.Inkampani yokubonelela ngombane inyanzelekile ukuba ivelise amandla ombane afanelekileyo kubathengi bobunjineli bamandla.Ke ngoko, inkampani yonikezelo lwamandla iphakamisa iimfuno zolawulo lwe-pulse ngoku kubasebenzisi abanokuthi bangcolise igridi.Njengoko uninzi lweenkampani zifuna umgangatho ophezulu wamandla, iinkampani zamandla ziya kubeka phambili iimfuno ezingqongqo kubathengi bobunjineli bamandla.
Ngokuqhelekileyo, ukulawulwa kwe-harmonic inxalenye kunye nolawulo lwe-harmonic oluphakathi lunokudibaniswa ukuvelisa isisombululo esineendleko.Kwimithwalo yemithombo ye-harmonic enegunya eliphezulu (ezifana ne-intermediate frequency induction furnaces, iziqalisi ezithambileyo, njl.).), kusetyenziswa izihluzi ze-ultra-high voltage ze-harmonic zolawulo lwe-harmonic yendawo ukunciphisa i-harmonic yangoku efakwe kwigridi yamandla.Kwimithwalo yenkqubo ecacileyo enamandla amancinci kunye namandla asasazwa ngokulinganayo, ulawulo olumanyeneyo kufuneka luqhutywe kwibhasi yenkqubo.Ungasebenzisa isihluzo esisebenzayo sikaHongyan okanye isihluzo sokwenziwa.
Ishishini lokusulungekiswa kunye neekhemikhali zesinyithi ezingenayo i-ferrous kufuneka lisebenzise inkqubo ye-electrolysis, ngoko ke isilungisi esinamandla aphezulu siyimfuneko.Abantu bathatha ukuveliswa kwe-hydrogen nge-electrolysis yamanzi njengomzekelo.Abantu kufuneka baqulunqe isethi ye-rectifier transformer kunye nekhabhinethi ye-thyristor yokulungisa.Indlela ye-ballast luhlobo lweenkwenkwezi eziphindwe kabini kwisigaba esithandathu.Umsinga otshintshayo owenziweyo usetyenziselwa iseli ye-electrolytic: 10KV/50HZ-rectifier transformer-phase voltage 172V*1.732 phase voltage 2160A-rectifier cabinet-AC 7200A/179V-electrolytic cell.Isiguquli sokulungisa: isigaba esithandathu sesibini esibuyela umva inkwenkwezi elungeleleneyo uthotho lwereactor okanye isigaba sesithathu sesigaba sesihlanu sesigaba esithandathu inkwenkwezi ebuyela umva.Umthamo womgca wokufakwayo: 1576 kVA ivolumu yevalve yecala 2230 kVA uhlobo lwevolumu 1902 kVA thyristor ikhabhinethi yokulungisa i-K671-7200 A / 1179 volts (iisethi ezine zizonke).Isixhobo sokuhlaziya siya kubangela i-pulsed current eninzi, eya kubeka emngciphekweni kakhulu umgangatho wamandla wegridi yamandla.
Kwinqanaba eliphezulu lesithathu-inqanaba elipheleleyo lebhulorho ye-6-pulse rectifier device, i-harmonics ye-high-order eyenziwa yi-akhawunti yokuhlaziya i-25-33% ye-harmonics yomyalelo ophezulu, oya kubangela umonakalo omkhulu kwigridi yamandla, kunye neempawu ze-harmonics ze-high-order ezenziweyo ziyi-6N±1 amaxesha, oko kukuthi, amaxesha eempawu kwicala levalvu yi-5th, 7th, 11th, 13th, 17th, 19th, 23rd, 25th, njl., kunye ne-5th kunye ne-7th ephezulu. amacandelo e-harmonic aveliswa yi-PCC iphuzu kwicala elikhulu lomnatha Impawu ze-harmonics eziphezulu ze-harmonics zikwicala elifanayo le-valve, phakathi kwayo i-5th order inkulu, kwaye i-7 iyancipha ngokulandelelana.Umsebenzi ohambelanayo weqela le-rectifier ye-rectifier kunye ne-phase-shifting windings ingenza i-pulses ezili-12, kwaye amaxesha eempawu zecala lenethiwekhi ngamaxesha angama-11, amaxesha angama-13, amaxesha angama-23, amaxesha angama-25, njl., kunye namaxesha e-11 kunye namaxesha angama-13 inkulu.
Ukuba akukho sixhobo sokucoca esifakwe kwicala legridi okanye kwicala levalvu, i-pulse epheleleyo yangoku efakwe kwigridi iya kudlula umgangatho woshishino wenkampani yethu, kwaye uphawu lwe-harmonic lwangoku olufakwe kwi-transformer ephambili luya kudlula ixabiso lolawulo umgangatho weshishini wenkampani yethu.I-harmonics ephezulu iya kubangela iintambo zokusabalalisa, ukufudumeza kwe-transformer, izixhobo zembuyekezo ezingasebenziyo azikwazi ukushiya i-factory, ukuthotywa komgangatho wonxibelelwano, ukungasebenzi kokutshintsha komoya, ukunyuka kwejeneretha kunye nezinye iimeko ezimbi.
Ngokuqhelekileyo, kuthungelwano lwamandla amakhulu enkqubo, i-harmonics ephezulu yophawu inokususwa ngokusebenzisa i-passive filter ( fc ) izixhobo, kunye neenjongo zokulawula zinokufezekiswa.Kwimeko yenkqubo yegridi yamandla amancinci, injongo yokujongana ne-harmonics ephezulu iphezulu.Ukongeza ekufakeni isixhobo esikhulu sokuhluza isixhobo sokucoca, isihluzo esinomthamo omncinci osebenzayo (apf) sinokusetyenziselwa ukufikelela kwimilinganiselo yomgangatho wamandla efunekayo.Kwisixokelelwano sofakelo lokuhlaziya ngeendlela ezahlukeneyo zoqhagamshelo, ufakelo lwethu lwembuyekezo yobuchwephesha bohluzo lunoyilo olwahlukileyo ekujoliswe kulo.Emva kokuvavanya kwisayithi, banokuthi "bazenzele ngokwezifiso" abathengi kwaye bakhethe isicwangciso sonyango esihambelana nemeko yangempela kwisayithi.
