Phase Control Thyristor (Mtundu Woyandama Waulere)

Kufotokozera:

Ndi chitukuko cha kuwonjezeka mphamvu ndi mphamvu zida zosinthira, makamaka HVDC kufala, linanena bungwe mphamvu mphamvu unit thyristor ndi pempho kuonjezera moyenerera, zimenezi kuchepetsa unsembe kuchuluka kwa thyristor mndandanda ndi dera kugwirizana kugwirizana.Kukula kwa chipangizocho ndi kulemera kwake kudzachepetsedwa, ndalama zochepetsera, ngakhale zamakono komanso ngakhale magetsi zidzakwaniritsidwa mosavuta, ntchito yodalirika ndi mtengo wamalonda udzawonjezeka kwambiri.

Ukadaulo wa silicon woyandama waulere womwe umagwiritsidwa ntchito popanga thyristor yamphamvu kwambiri wamakono udzakwaniritsa zofunikira pakugwiritsa ntchito.Ndipo mu Julayi 2019, RUNAU Electronics idapanga 5200V thyristor yokhala ndi 5 ”chip bwino ndikuperekedwa kwa kasitomala yemwe adagwiritsa ntchito ku China HVDC project.

Chiyambi:

1. Chip

Chip chapamwamba kwambiri cha thyristor chopangidwa ndi RUNAU Electronics ndiukadaulo woyandama waulere womwe umayikidwa.Ndizodziwika bwino monga ukadaulo waposachedwa komanso wokhwima wopanga mphamvu yayikulu yamagetsi a thyristor.Amagwiritsidwa ntchito kwambiri ndi opanga apamwamba kwambiri padziko lonse lapansi.

Njira yophatikizira idakongoletsedwa mu kachulukidwe ndi m'lifupi kuti iwonjezere kukana kwamagetsi, kutsitsa kutsika kwamagetsi paboma, ndikuwongolera zoyambitsa & mawonekedwe amphamvu.Njira yatsopano yojambula zithunzi idapangidwa kuti ipititse patsogolo mawonekedwe a di/dt ndi dv/dt.Kapangidwe ka chip kamangidwe kadamangidwanso kuti ateteze m'mphepete mwa silicon wafer ndi cathode pamwamba, magwiridwe antchito am'mbuyo azikhala bwino kwambiri.

2. Kufotokozera

Ubwino waukadaulo wa silicon woyandama waulere ndikupindika pakati pa silicon ndi molybdenum wafer wokhazikika kwambiri komanso kuchepetsedwa kwa mowa wa molybdenum wafer.Ngakhale kupendekeka kwa silicon wafer ndi chipika chamkuwa ndizofunikira kwambiri komanso kufanana ndi kukhwimitsa komwe kumafunikira ndizokwera kuposa ukadaulo wa alloying chip.Pakutukuka kosalekeza komanso kusinthika kwatsopano, RUNAU Electronic idagonjetsa zovuta zonse zaukadaulo ndi zopinga.Ukadaulo woyandama waulere, mphamvu yayikulu yamagetsi yamtundu wa thyristor yokhala ndi magwiridwe antchito odalirika komanso njira yabwino yamalonda idapangidwa ndikuperekedwa kwa makasitomala.Ambiri aiwo amaikidwa mu chowongolera champhamvu chowongolera mphamvu, choyambira chofewa champhamvu kwambiri, kutumizira mphamvu kwa HVDC, kukoka kwa locomotive, chipukuta misozi champhamvu komanso makina ogwiritsira ntchito mphamvu zamagetsi.

Kufotokozera zaukadaulo

1. Phase controlled thyristor yokhala ndi alloy type chip yopangidwa ndi RUNAU Electronics, osiyanasiyana I_{Mtengo wa TAV}kuchokera ku 350A mpaka 5580A ndi V_DRM/V_RRMkuchokera 3400V mpaka 8500V.
2. I_GT, V_GTndi ine_Hndi miyeso yoyesa pa 25 ℃, pokhapokha ngati tafotokozera, magawo ena onse ndi mayeso omwe ali pansi pa T._jm;
3. I²t=ine²F SM×tw/2,tw= Sinusoidal theka la mafunde apano m'lifupi.Pa 50Hz, I²t=0.005I²FSM(A²S);
4. pa 60Hz:I_{Mtengo wa FSM}(8.3ms)=ine_{Mtengo wa FSM}(10ms)×1.066,T_j=T_j;Ine²t(8.3ms)=ine²T(10ms)×0.943,T_j=T_jm
