Izindi Nteko Zimbaraga
Imbaraga zigenga ibikoresho byateguwe kandi bikozwe hamwe nibikoresho bya elegitoroniki yingufu hamwe nibyiza byo guhitamo byoroshye, kwizerwa cyane, igiciro gito cyuzuye, kwishyiriraho byoroshye, kugaragara neza, kwihuta kwiterambere, nibindi.
Inteko zimbaraga zakozwe na thyristor na diode ziboneka gutangwa:
• Icyiciro kimwe cyo gukosora ikiraro: harimo icyiciro kimwe cyuzuye kugenzura, igice cyo kugenzura, hamwe nikiraro gikosora
• Ibyiciro bitatu byuzuye-ikiraro cyuzuye: harimo ibyiciro bitatu byo kugenzura byuzuye, gukosora ibyiciro bitatu byo kugenzura, hamwe nicyiciro cya gatatu cyo gukosora.
• Icyiciro cya gatandatu cyo gukosora ikiraro cyuruhererekane: harimo ibyiciro bitandatu bigenzurwa kandi bitagenzurwa nibiraro bikosora
• Urukurikirane rwa AC: harimo icyiciro kimwe nicyiciro cya gatatu cya AC
Kubindi bibazo byinshi byiteraniro ryimbaraga zakozwe na thyristor, diode na rectifier kugirango bikosorwe, bihindurwe, guhinduranya amashanyarazi no kugenzura, nyamuneka twandikire, itsinda rishinzwe gufasha abakiriya bafite impano nabatekinisiye babimenyereye barimo gukorera.
Uburyo bukonje bwo guterana ni gukonjesha ikirere, gukonjesha bisanzwe, no gukonjesha amazi hamwe na aluminiyumu hamwe nu muyoboro w'ubushyuhe.
• Ibigize inteko ni amashanyarazi, ubushobozi bwo kwinjiza RC, kurinda ubushyuhe, rusange cyangwa ibikorwa byihariye byo kugenzura.
Intangiriro ya tekiniki
- Ibice bitatu-birwanya ingufu zingana bigizwe na SCR ebyiri ihujwe muburyo bwo kurwanya-parallel kuri buri cyiciro kugirango tumenye amashanyarazi agenzurwa na AC.Buri thyristor ikora kugirango ihuze ibyiza nibibi byikurikiranya.Guhuza rero ibipimo byibice bibiri birwanya guhuza SCR ni ngombwa cyane kimwe nibiranga irembo no gufata ibipimo bigezweho, nibindi. Guhuza kwa thyristors ukoreshwa bizatanga igice cyiza kandi kibi cya kabiri cyuzuzanya, naho ubundi ikigezweho na DC ibice bizanyura muri moteri yerekana ibintu, moteri ya moteri izashyuha cyane, hanyuma moteri ya moteri izatwikwa kandi moteri yangiritse amaherezo.
- Runau irashobora gutanga icyiciro gihanitse kigenzurwa na thyristor hamwe nicyiciro 3 kijyanye na anti-parallel power power muri voltage yo hagati ya 1200V / 3300V ariko kandi na voltage nini ya 4500V / 6500V.
- Kugirango umenye gutangira byoroshye no kurinda moteri ya 6kV na 10kV ya moteri ndende, birakenewe ko uhuza SCR muri anti-parallel hanyuma ukayihuza murukurikirane kugirango wuzuze ibisabwa byumuvuduko mwinshi.Buri cyiciro cya 6kV gisaba thyristors 6 (2 muri anti-parallel hamwe nitsinda 3 murukurikirane), kandi buri cyiciro cya 10kV gisaba thyristors 10 (2 muri anti-parallel, amatsinda 5 murukurikirane).Muri ubu buryo, voltage yihanganira buri thyristor igera kuri 2000V, bityo rero imbere no gusubiza inyuma bidasubirwaho voltage VDSM na VRSM ya thyristor yatoranijwe igomba kuba 6500V cyangwa hejuru.Kugirango uhitemo igipimo cyagenwe cya thyristor, igipimo cyimikorere ya moteri kigomba gusuzumwa.Mubisanzwe, ibyatoranijwe byatoranijwe bya thyristor bigomba kuba inshuro 3 kugeza kuri 4 za moteri yagenwe.
