Yakakosha sefa yekuripa mudziyo weHYFCKRL akatevedzana akanyura arc vira
rondedzero yechigadzirwa
Mhando huru uye mashandisirwo eakanyura arc furnaces
Iyo undermerged arc furnace iindasitiri yemagetsi vira inopedza simba rakawanda.Iyo inonyanya kuve negoko rechoto, chivharo chechoto, chivharo chechoto, mambure mapfupi, kutonhora kwemvura, utsi epositi system uye guruva rekubvisa system, electrode inotsikirira goko, electrode kudzvanya nekusimudza sisitimu, kurodha nekuburitsa sisitimu, gripper, burner, hydraulic system yakanyura. arc furnace transformer uye zvakasiyana-siyana zvemagetsi
Zvinoenderana nehunhu hwemagadzirirwo uye hunhu hwekushanda hwearc furnace yakanyura, 70% yeiyo system reactance yeyakadzika arc furnace inogadzirwa neiyo pfupi network system, uye kurasikirwa kwehurongwa kweiyo yakadzika arc vira inoratidzwa mumufananidzo uri pazasi.
Kuenzaniswa ne-high-voltage compensation, zvakanakira zve low-voltage compensation zvinonyanya kuratidzwa mune zvinotevera zvinhu mukuwedzera pakuvandudza simba chinhu:
(1) Kuvandudza chiyero chekushandiswa kwevashanduri uye mitsetse yepamusoro-yazvino, uye kuwedzera simba rekuisa rinoshanda rekunyungudutsa.Kune arc smelting, chizvarwa chesimba rinoshanda rinonyanya kukonzerwa nearc current.Nzvimbo yekubhadhara inoendeswa mberi kunetiweki pfupi, uye nhamba huru yemapfupi network inobhadharwa munharaunda.Reactive mashandisirwo emagetsi, wedzera vhezheni yekupinza yemagetsi emagetsi, wedzera kubuda kwe transformer, uye wedzera iro rinoshanda rekuisa simba rekunyungudutsa.Kunyunguduka kwechigadzirwa ibasa remagetsi e electrode uye kushorwa chaiko kwezvinhu, izvo zvinogona kungoratidzwa seP = U 2 / Z zvinhu.Nekuda kwekuvandudzwa kwesimba remutoro weiyo transformer, simba rekupinza reshanduko kuchoto rinowedzerwa, kuitira kuti uone kuwedzera kwekugadzira uye kuderedzwa kwekushandisa.
(2) Unbalance muripo wekuvandudza mamiriro akasimba uye asina simba echikamu chezvikamu zvitatu.Sezvo kurongeka kwematatu-chikamu mapfupi network uye muviri wechoto uye midziyo yevira inogara isina kuenzana, madonhwe akasiyana-siyana emagetsi uye masimba akasiyana ezvikamu zvitatu zvinotungamirira kuzvikamu zvakasimba uye zvisina simba.kuumbwa kwechikamu.Single-phase parallel connection inotambirwa kuti iite reactive simba muripo, muripo wechikamu chimwe nechimwe unogadziridzwa zvakazara, kusimba kwesimba rechoto chepakati uye kufanana kwekuwana kunovandudzwa, iyo inoshanda inoshanda voltage yeatatu-phase electrodes inowirirana, iyo electrode voltage yakaenzana, uye chidimbu chetatu chekudya chakaenzana, kuvandudza katatu-chikamu Chikamu chakasimba uye chisina simba chezvikamu zvinogona kuzadzisa chinangwa chekuwedzera kugadzirwa uye kuderedza kushandiswa.Panguva imwecheteyo, inogona kuvandudza chiitiko chisina kuenzana chezvikamu zvitatu, kuvandudza nzvimbo yekushanda yevira, uye kuwedzera hupenyu hwebasa rechoto.
(3) Deredza kurongeka kwepamusoro-soro, kuderedza kukuvadzwa kweharmonics kune ese magetsi ekushandisa, uye kuderedza kumwe kurasikirwa kwevashanduri uye network.
(4) Hunhu hwesimba hwakavandudzwa.Naizvozvo, mamwe mayuniti akatora reactive simba muripo matanho payakaderera-voltage kupera kugadzirisa matambudziko ari pamusoro.Kubhadhara pamagumo ekupedzisira-grid kunogona kuvandudza zvakanyanya simba rekupedzisira rekupedzisira-grid uye kuderedza kushandiswa kwesimba.Huwandu hukuru hwekushandiswa kwesimba rekushandisa uye kusaenzana kweiyo pfupi network padivi rakadzika-voltage yechoto cheshanduko, tichifunga nezve kuvandudzwa kunobudirira kwesimba remagetsi uye kuita shanduko yehunyanzvi yesimba reactive pa-saiti muripo, inovimbika nehunyanzvi. uye vakura, uye nekutaura mune zveupfumi, kupinza uye kubuda kunoenzanirana.Padivi rakadzika-voltage yearc furnace yakanyura, iro reactive simba pa-saiti muripo rinoitwa kune pfupi-circuit reactive simba rekushandisa uye matatu-phase unbalance phenomenon ine isingaenderane magadzirirwo kureba, ingave iri kuvandudza iyo simba chinhu, inonwisa. harmonics, kana kuwedzera kugadzirwa uye kuderedza kushandiswa.Vese vane mabhenefiti asingaenzaniswi emuripo wemagetsi akakwira.Nekudaro, nekuda kwehuwandu hukuru hwekuchinja shanduko mune yechinyakare muripo wekuchinja tekinoroji (sekushandisa AC contactor switching), mutengo wekuchinja switch wakakwira, uye panguva imwe chete, nekuda kwenzvimbo yekushanda yakaoma, hupenyu hwesevhisi. zvakakanganiswa zvikuru.Hupenyu hwesevhisi hwekubhadharisa kwakaderera-voltage nekuchinja kwechinyakare kwakaoma kudarika gore, saka zvinounza kuchengetedzwa kwakawanda kune bhizinesi, uye nguva yekudyara yekudyara inorebeswa.Nekuda kwemitengo yakakwira yekutevera yekuchengetedza, iyo yakazara mabhenefiti haina kunaka.

Technical Parameters
● Zvikamu zvitatu zvinobhadharwa zvakasiyana kuti zvideredze kusaenzana kwezvikamu zvitatu uye zvinobudirira kuwedzera kugadzirwa uye kuderedza kushandiswa.Kuvandudza kudonha kwevoltage uye flicker kudzvinyirira 3rd, 5th, 7th harmonic kusvibiswa uye ziva kusununguka kushandura chero nguva.
● Kuvimbika kwekuchinja kwakakwirira, uye nguva dzekuchinja kwekuchinja kwekuchinja pasina kukanganisa kunogona kusvika mamiriyoni akawanda nguva.Ndiko kakapetwa kakapetwa hupenyu hweakajairika switch.Nekuda kweiyo yakakwira-yazvino vacuum yekubatisa switching, kupikisa kwemaitiro kwakanaka, uye inogona kusvika kakapetwa kakapetwa kanopfuura-ikozvino kukanganisa pasina kukuvara.Iko hakuna inrush ikozvino kana yaiswa, hapana overvoltage kana yagurwa.
●Kuvimbika kwepamusoro, kuchengetedza-kusina uye kusina kutarisirwa
● Yepamberi isiri-inokurumidza-fuse kudzivirira dhizaini inodzivirira kukuvadzwa kune capacitors uye vacuum contactors kusvika pamwero mukuru.Zvinonyanya kunatsiridza mwero wekushandiswa kwesimba rekupa simba.
