Ukufakwa komthwalo Kusetyenziswa kakhulu ekunyibilikiseni nasekufudumezeni iintsimbi ezingezizo i-ferrous kunye ne-ferrous.Njengentsimbi etyhidiweyo kwizinyibilikisi, intsimbi jikelele, ipleyiti yentsimbi, intsimbi yealloyi, ubhedu, i-aluminiyam, igolide, isilivere kunye ne-aluminium alloy, njl.Intsimbi kunye neendawo zobhedu zokubumba i-diathermy, ii-ingots ze-aluminiyam zokubumba i-extrusion, njl. Ukuqhuba unyango lokucima kunye nokufudumala olufana nonyango lobushushu kunye nonyango lobushushu kwizinto zetsimbi.Isixhobo sokufudumeza isithando somlilo esiphakathi sincinci ngobukhulu, silula ngobunzima, siphezulu ngokusebenza kakuhle, sigqwesa kumgangatho wokusetyenzwa kwe-thermal, kwaye siyavumelana nokusingqongileyo.Sisizukulwana esilandelayo sezixhobo zokufudumeza zetsimbi zokuphelisa ngokukhawuleza izitofu ezibaswa ngamalahle, iziko legesi, iziko le-oyile, kunye nezitofu eziqhelekileyo zokumelana.
Layisha iimpawu ze-harmonic;Iziko eliphakathi lokunyibilikisa lisetyenziswa ngokubanzi nangakumbi ekunyibilikiseni, ukuphosa kunye namanye amashishini.Nangona kunjalo, xa usebenza, isithando somlilo esiphakathi esiphakathi samkela itekhnoloji yokulungiswa kunye ne-inverter, okukhokelela kwinani elikhulu leeharmonics zangoku kunye ne-voltage.Ungcoliseko lweHarmonic kwinkqubo yonikezelo lwamandla yenza izixhobo ezichanekileyo zisebenze kwinkqubo yempazamo kwaye kwandisa ilahleko yezixhobo zokubonelela ngombane.Inkqubo yombane ye-intermediate frequency induction furnace ngumthombo wangoku we-pulse enkulu kwinkqubo yonikezelo lwamandla, kwaye kukho ngokubanzi ukutshintshwa kombane okhoyo kwiziko eliphakathi lokungeniswa kwamaza ombane kunye neziko eliphezulu lokungeniswa kwamaza.Ngokubanzi, ii-furnaces ezi-6 ze-pulse intermediate intermediate frequency induction ikakhulu zivelisa iimpawu ze-harmonics ze-5, i-7, i-11, kunye ne-13 amaxesha.Kwi-12 ye-converter eyodwa ye-converter intermediate frequency induction furnaces, i-harmonics engundoqo yi-harmonics ye-11, i-13, i-23 kunye ne-25.Ngokuqhelekileyo, ii-pulses ezi-6 zisetyenziselwa izixhobo ezincinci zokuguqula, ii-pulses ze-12 zisetyenziselwa izixhobo zokuguqula ezinkulu, ezifana ne-Y / △ / Y uhlobo lwe-furnace transformer, okanye i-2 i-furnace transformer isetyenziselwa inkqubo yokubonelela umbane.
Ngokweengxaki ezifunyenwe kwimisebenzi ebonakalayo, umxholo wokufuma we-harmonic we-furnace ye-intermediate frequency ungaphantsi kwe-85%, kodwa iimveliso zokugcinwa kwenkqubo zilawulwa ikakhulu yi-harmonics, ukuphuculwa kwee-harmonics kunokungahoywa ngokusisiseko, kunye nefuthe lokonga amandla. ayanelisi.Okona kubi kakhulu kukuba amandla e-harmonic adlula kakhulu uluhlu oluvumelekileyo lokugcinwa kwamandla kunye nezixhobo zokukhusela indalo, kwaye kulula ukonakala emva kokusetyenziswa kwexesha elide, kwaye iingozi zenzeke rhoqo.Ke ngoko, ekuphenduleni umnqweno ongxamisekileyo weemveliso ezininzi zokugqibela, ukukhuselwa kwendalo kunye nokugcinwa kwamandla kwiziko eliphakathi kwamaza ombane kuye kwaba yingxaki yexesha elide kwishishini lokusetyenziswa kwamandla, eliphazamisa amashishini amaninzi kunye namashishini.
1. Isithando somlilo esiphakathi sivelisa inani elikhulu lee-harmonics ngexesha lokusetyenziswa, kwaye ungcoliseko lwe-harmonic kwigridi yamandla iba mbi kakhulu.
2. I-Harmonics iya kunciphisa ukusebenza kakuhle kokuhanjiswa kwamandla kunye nokusetyenziswa, ukutshisa kakhulu izixhobo zombane, ukuvelisa ukungcangcazela kunye nengxolo, ukugquma okonakalisayo, ukunciphisa ubomi, kunye nokungasebenzi kakuhle kunye nokutshisa.
3. IiHarmonics ziya kubangela i-resonance parallel resonance yendawo kunye nothotho lweresonance yesistim yamandla,
4. Ukwandisa umxholo we-harmonic, utshise izixhobo zembuyekezo ye-capacitance kunye nezinye izixhobo;
5. I-Harmonics ibangela ukukhuselwa kwe-relay kunye nokungasebenzi kakuhle kwesixhobo;
5. Ngaphandle kwenkqubo yamandla, i-harmonics iphazamisa kakhulu izixhobo zonxibelelwano kunye nezixhobo zombane.
6. Ukuba i-power factor ayihambelani nemigaqo ye-0.90 ye-bureau yokubonelela ngombane, isohlwayo sokulungelelanisa umrhumo wombane siya kumiselwa.
7. Umbane ophantsi wesithando somlilo esiphakathi kunye nomthamo omkhulu womthwalo osebenzayo onikezelwa yi-transformer ekhethekileyo ukwandisa umthwalo kwi-transformer.
8. Kwakhona kukho imeko: amandla ombane wabathengi abathile bama-furnaces e-intermediate frequency induction ayiphantsi xa befakwa ekusebenzeni, kwaye kufuneka balawule i-pulse current.
Ke ngoko, ukuphucula umgangatho wamandla wesithando somlilo esiphakathi kube sisitshixo sokuphendula.Izisombululo onokukhetha kuzo:
isicwangciso 1
Ulawulo olusembindini (faka izihluzi zeharmonic kwigumbi lokuhambisa amandla elilungele ukusebenza ngaxeshanye kwiziko lombane lamaxesha amaninzi aphakathi)
1. Sebenzisa isebe lolawulo lwe-harmonic (5, 7, 11 filter) + isebe lolawulo lwamandla asebenzayo.Emva kokuba isixhobo sembuyekezo yesihluzi sifakwe ekusebenzeni, ulawulo lweharmonic kunye nembuyekezo yamandla asebenzayo wenkqubo yonikezelo lwamandla ihlangabezana neemfuno.
2. Yamkela isihluzi esisebenzayo (susa ucwangco lwe-harmonics eguquguqukayo) kunye ne-harmonic countermeasure yesekethe yesebe (5, 7, 11 icebo lokucoca) # + uhlengahlengiso olungasebenziyo lwesekethe yesebe, kwaye emva kokubonelela kwisixhobo sembuyekezo yesihluzo, beka phambili Isicelo sembuyekezo engasebenziyo inkqubo yonikezelo lwamandla.
Imeko yesi-2
Ulawulo olukwisiza (seta isixhobo sokucoca i-harmonic kwindawo ephezulu ecaleni kwephaneli yombane yesithando somlilo esiphakathi)
1. Yamkela i-anti-harmonic bypass (5th, 7th, 11th filter), ukulandelela ngokuzenzekelayo ukusebenza kwesithando somlilo esiphakathi, ukusombulula i-harmonics kwisayithi, kwaye ungachaphazeli ukusebenza kwezinye izixhobo ngexesha lokuvelisa, kwaye i-harmonics ayifiki. umgangatho emva kokusetyenziswa.
2. I-Adopt filter esebenzayo (i-bandwidth adjustment unit) kunye ne-filter bypass circuit (i-5th, i-7th filter), i-harmonics ye-high-order emva kokutshintsha ayifikeleli kwi-benchmark.
Ukhetho 3:
Iquka ulawulo oluphinda-phindayo lwamandla aphezulu okucoca amandla asebenzayo.Amandla ethu eHongyan APF azimele yedwa ane-100A, 200A, 300A, 500A kunye nezinye iinkcukacha, kwaye iiyunithi ezi-6 zinokuhambelana.Iphatha intsebenziswano yazo zonke iiperi zefrikhwensi.
