Zida Zamagetsi Zamagetsi Zopangira Kuwotcha

Kutentha kwapang'onopang'ono kumagwiritsidwa ntchito makamaka kusungunula zitsulo, kuteteza kutentha, sintering, kuwotcherera, kuzimitsa, kutentha, diathermy, kuyeretsa zitsulo zamadzimadzi, chithandizo cha kutentha, kupindika kwa chitoliro, ndi kukula kwa kristalo.Mphamvu yopangira magetsi imakhala ndi rectifier circuit, inverter circuit, load circuit, control and protection circuit.

Ukadaulo wapakatikati wamagetsi otenthetsera ndi ukadaulo womwe umawongolera ma frequency amagetsi apano (50Hz) kuti awongolere mphamvu kenako amasintha kukhala ma frequency apakatikati (400Hz~200kHz) kudzera pazida zamagetsi za semiconductor monga thyristor, MOSFET kapena IGBT.Ukadaulo umakhala ndi njira zowongolera zosinthika, mphamvu yayikulu yotulutsa, komanso magwiridwe antchito apamwamba kuposa unit, komanso yabwino kusintha ma frequency malinga ndi kutentha komwe kumafunikira.

Kukonzanso kwa zida zazing'ono ndi zapakatikati zopangira magetsi kutengera kukonzanso kwa magawo atatu a thyristor.Pazida zamagetsi zamphamvu kwambiri, 12-pulse thyristor rectification idzagwiritsidwa ntchito kuti ipititse patsogolo mphamvu yamagetsi ndikuchepetsa mphamvu yamagetsi yamagetsi.The inverter power unit imapangidwa ndi high-voltage high-current fast switch thyristor parallel ndiye mndandanda wolumikizidwa kuti uzindikire kutulutsa kwamphamvu kwambiri.

Inverter ndi resonant dera akhoza kugawidwa mu mitundu iwiri malinga ndi katundu structural: 1) kufanana resonant mtundu, 2) mndandanda resonant mtundu.

Mtundu wa resonant wofanana: high-voltage high-current water-cooled thyristor (SCR) imagwiritsidwa ntchito popanga magetsi amtundu wamakono, ndipo kutulutsa mphamvu kwapamwamba kumazindikiridwa ndi superposition of thyristors.Dera la resonant nthawi zambiri limagwiritsa ntchito mawonekedwe athunthu a resonance, amasankhanso ma voltages awiri kapena thiransifoma kuti awonjezere voteji pa inductor malinga ndi zofunikira zosiyanasiyana, zomwe zimagwiritsidwa ntchito kwambiri pakuwotcha.

Series resonant mtundu: high-voltage mkulu-panopa madzi utakhazikika thyristor (SCR) ndi kudya diode ntchito kupanga voteji-mtundu inverter mphamvu wagawo, ndi mkulu mphamvu linanena bungwe anazindikira ndi superposition wa thyristors.Dera la resonance limagwiritsa ntchito mawonekedwe amtundu wa resonance, ndipo thiransifoma imatengedwa kuti ifanane ndi zomwe zimafunikira.Kuphatikiza pazabwino zamphamvu yamagetsi pa Grid-mbali, kusintha kwamphamvu kwamitundu yonse, kutentha kwambiri komanso kuthamanga kwapamwamba koyambira, kwagwiritsidwa ntchito kwambiri m'zaka zapano ndipo kumagwiritsidwa ntchito makamaka pakusungunuka.

Pambuyo pokonza njira zopangira, Runau yopangidwa ndi thyristor yofulumira imagwiritsa ntchito ma radiation ya nyutroni ndi njira zina kuti ifupikitse nthawi yozimitsa ndipo mphamvu yamagetsi imapangidwanso bwino.

Kutentha kwapakati pamagetsi opangira magetsi kumatenga thyristor popeza chipangizo chachikulu chamagetsi chaphimba madera onse ndi ma frequency opitilira 8kHz.The linanena bungwe mphamvu mphamvu anawagawa 50, 160, 250, 500, 1000, 2000, 2500, 3000kW, 5000KW, 10000KW pafupipafupi ntchito ndi 200Hz, 400Hz, 1kHz, 2.4kHz, 8kHz, 8kHz.10 matani, 12 matani, 20 matani zitsulo kusungunuka ndi kusungitsa matenthedwe, chachikulu zida mphamvu ndi sing'anga pafupipafupi magetsi.Tsopano mphamvu yayikulu yotulutsa mphamvu imabwera ku 20000KW ya 40Ton.Ndipo thyristor ndiye chinthu chofunikira kwambiri chosinthira mphamvu & chigawo chosinthika kuti chigwiritsidwe ntchito.
