Na'urorin Lantarki na Wutar Lantarki Na Dumamar Induction

Ana amfani da dumama shigar da galibi don ƙarfe, adana zafi, sintering, walda, quenching, tempering, diathermy, tsabtace ƙarfe na ruwa, maganin zafi, lankwasa bututu, da haɓakar crystal.Ƙaddamarwar wutar lantarki ta ƙunshi da'ira mai gyarawa, da'irar inverter, da'irar kaya, sarrafawa da kewayen kariya.

Matsakaicin fasahar samar da wutar lantarki don dumama shigar da wutar lantarki fasaha ce da ke gyara canjin wutar lantarki na yanzu (50Hz) zuwa wutar lantarki sannan ta juya zuwa matsakaicin mitar (400Hz ~ 200kHz) ta hanyar na'urorin semiconductor irin su thyristor, MOSFET ko IGBT.Siffofin fasaha a cikin hanyoyin sarrafawa masu sassauƙa, babban ƙarfin fitarwa, da inganci mafi girma fiye da naúrar, kuma dacewa don canza mita bisa ga buƙatun dumama.

Mai gyara na'urorin samar da wutar lantarki kanana da matsakaita yana ɗaukar gyare-gyaren thyristor kashi uku.Don kayan aikin samar da wutar lantarki mai ƙarfi, za a yi amfani da gyaran gyare-gyare na 12-pulse thyristor don haɓaka matakin ƙarfin wutar lantarki da rage yanayin jituwa na grid-gefe.The inverter ikon naúrar ya ƙunshi high-voltage high-current fast canji thyristor a layi daya sa'an nan jerin alaka don gane babban ikon fitarwa.

Inverter da resonant kewaye za a iya raba iri biyu bisa ga tsarin Properties: 1) layi daya resonant type, 2) jerin resonant irin.

Parallel resonant type: high-voltage high-current water-seedy thyristor (SCR) ana amfani da shi don samar da na'urar inverter mai nau'in halin yanzu, kuma ana samun babban fitarwa ta hanyar superposition na thyristors.Da'irar resonant gabaɗaya tana amfani da cikakken tsarin rawa mai kama da juna, kuma zaɓi yanayin ƙarfin lantarki biyu ko na'ura mai canzawa don ƙara ƙarfin lantarki akan inductor bisa ga buƙatu daban-daban, galibi ana amfani da shi a cikin tsarin dumama jiyya.

Series resonant type: high-voltage high-current ruwa-sanya thyristor (SCR) da sauri diode ana amfani da su samar da wani irin ƙarfin lantarki-type inverter ikon naúrar, da kuma high ikon fitarwa da aka gane ta superposition na thyristors.Da'irar resonance tana amfani da tsarin resonance na jerin gwano, kuma ana ɗaukar na'urar ta atomatik don dacewa da buƙatun kaya.Bugu da kari ga abũbuwan amfãni daga high ikon factor a Grid-gefe, m ikon daidaita kewayon, high dumama yadda ya dace da kuma high farawa-up nasara kudi, shi ke zama mafi kuma mafi ko'ina amfani a halin yanzu shekaru da yafi amfani a narkewa tsari.

Bayan inganta aikin masana'antu, Runau ya ƙera mai saurin sauya thyristor yana amfani da radiation neutron da sauran hanyoyin don ƙara rage lokacin kashewa kuma ƙarfin wutar lantarki ya inganta saboda haka.

Induction dumama matsakaicin mitar wutar lantarki yana ɗaukar thyristor kamar yadda babban na'urar wutar lantarki ta rufe duk filayen tare da mitar aiki ƙasa da 8kHz.The fitarwa ikon iya aiki ne zuwa kashi 50, 160, 250, 500, 1000, 2000, 2500, 3000kW, 5000KW, 10000KW da aiki mita ne 200Hz, 400Hz , 1kHz, 2.5kHz, 8kHz, 8kHz10 ton, ton 12, ton 20 don narkewar ƙarfe da ajiyar zafi, babban kayan aikin wutar lantarki shine matsakaicin mitar wutar lantarki.Yanzu matsakaicin ƙarfin fitarwa ya zo 20000KW na 40Ton.Kuma thyristor shine mabuɗin ikon juyawa & ɓangaren juzu'i da za a yi amfani da shi.
