Magulu Ena Amphamvu
Zida zowongolera mphamvu zomwe zidapangidwa ndikupangidwa ndi zida zamagetsi zamagetsi zomwe zimakhala ndi zabwino kusankha kosavuta, kudalirika kwakukulu, mtengo wotsika, kuyika kosavuta, mawonekedwe abwino, kuthamanga kwachitukuko, ndi zina.
Magulu amphamvu opangidwa ndi thyristor ndi diode omwe akupezeka kuti aperekedwe:
• Single-phase rectifier rectifier bridge series: kuphatikizapo chiwongolero chonse cha gawo limodzi, kuwongolera theka, ndi mlatho wokonzanso
• Mlatho wathunthu wa magawo atatu: kuphatikiza kuwongolera kwathunthu kwa magawo atatu, kuwongolera magawo atatu, ndi mlatho wowongolera magawo atatu.
• Mlatho wokonzanso magawo asanu ndi limodzi: kuphatikiza milatho ya magawo asanu ndi limodzi otheka kuwongolera komanso osasinthika
• Zosintha za AC: kuphatikiza magawo amodzi ndi magawo atatu a AC
Pamafunso owonjezera amagetsi opangidwa ndi thyristor, diode ndi rectifier kuti akonzenso, kusintha, kusintha mphamvu ndi kuwongolera, chonde tifunseni, gulu lothandizira makasitomala lomwe lili ndi talente komanso akatswiri odziwa zambiri likugwira ntchito.
• Njira zoziziritsira misonkhano ndizoziziritsa mpweya, kuziziritsa kwachilengedwe, ndi kuziziritsa kwamadzi ndi mbiri ya aluminiyamu ndi chitoliro cha kutentha.
• Zigawo zamisonkhano ndi mphamvu yamagetsi, RC mayamwidwe capacitor, chitetezo cha kutentha, zigawo zikuluzikulu kapena zapadera zolamulira.
Mau Otsogolera Aukadaulo
- Gawo lachitatu la mphamvu zotsutsana ndi kufanana limapangidwa ndi ma SCR awiri olumikizidwa munjira yotsutsana ndi gawo lililonse kuti azindikire kuwongolera kwamagetsi koyendetsedwa ndi gawo la AC.Chilichonse cha thyristor chimagwira ntchito molingana ndi theka labwino komanso loyipa.Choncho kugwirizana kwa magawo awiri odana ndi kufanana olumikizidwa SCR n'kofunika kwambiri komanso makhalidwe pachipata ndi kugwira magawo panopa, etc. kugwirizana kwa thyristors ntchito adzapereka zabwino ndi zoipa theka mafunde kukhala symmetrical, apo ayi panopa ndi DC. chigawocho chidzadutsa mu inductive feature motor, motor stator idzatenthedwa kwambiri, kenako ma windings a motor adzawotchedwa ndipo galimotoyo idzawonongeka potsiriza.
- Runau angapereke mkulu kugwirizana gawo ankalamulira thyristor ndi zokhudzana 3 gawo odana kufanana mphamvu wagawo mu sing'anga voteji 1200V/3300V komanso mkulu voteji wa 4500V/6500V.
- Kuzindikira chiyambi zofewa ndi kuteteza 6kV ndi 10kV mkulu voteji Motors, m'pofunika kulumikiza SCRs odana kufanana ndiyeno kulumikiza iwo mu mndandanda kukwaniritsa mkulu voteji ntchito chofunika.Gawo lirilonse la 6kV limafuna 6 thyristors (2 mu anti-parallel ndi magulu 3 mu mndandanda), ndipo gawo lirilonse la 10kV limafuna 10 thyristors (2 mu anti-parallel, magulu 5 mndandanda).Mwa njira imeneyi, voteji analekerera aliyense thyristor ndi za 2000V, kotero kutsogolo ndi n'zosiyana sanali mobwerezabwereza oveteredwa voteji VDSM ndi VRSM wa thyristor anasankha ayenera 6500V kapena pamwamba.Kusankha pakali pano wa thyristor, ovotera pakali pano wa injini ayenera kuganiziridwa.Nthawi zambiri, mawonekedwe osankhidwa a thyristor ayenera kukhala 3 mpaka 4 nthawi zamagalimoto ovotera pano.
