Xakamaynta Wajiga Thyristor (Nooca Sabaynta Xorta ah)

Sharaxaad:

Iyadoo horumarinta kororka awoodda iyo awoodda qalabka beddelka, gaar ahaan gudbinta HVDC, awoodda wax soo saarka ee thyristor unit waa codsi in la kordhiyo si waafaqsan, sida hoos u dhigi doonaa tirada rakibaadda thyristor ee taxane iyo isku xirka isku midka ah.Cabbirka qalabka iyo miisaanka ayaa la dhimi doonaa, maalgashiga hoose, xitaa hadda iyo xitaa korantada ayaa si fudud loo xaqiijin doonaa, hawlgalka lagu kalsoonaan karo iyo qiimaha ganacsiga ayaa si weyn loo kordhin doonaa.

Tiknooloojiyada silikoon ee sabbaynaysa ee bilaashka ah ee loo isticmaalo soo saarista tamarta sare ee thyristor hadda waxay qancin doontaa shuruudaha codsiga heerka sare.Bishii Luulyo 2019, RUNAU Electronics waxay soo saartay 5200V thyristor oo leh 5" chip si guul leh oo la siiyay macaamiisha ka codsaday Shiinaha HVDC mashruuca.

Hordhac:

1. Chip

Chip-ka thyristor-ga heerka sare ah ee ay samaysay RUNAU Electronics waa tignoolajiyad sabbaynaysa oo bilaash ah.Waa tignoolajiyada ugu dambaysay uguna qaan-gaadhka ah ee loogu talagalay soo saarista tamarta sare ee thyristor.Waxaa si ballaaran u isticmaala soosaarayaasha heerka caalami ee ugu badan.

Habka fidinta waxaa lagu hagaajiyay cufnaanta iyo ballaca si loo kordhiyo iska caabinta korantada, loo yareeyo hoos u dhaca korantada ee gobolka, loona wanaajiyo kicinta & sifooyinka firfircoon.Qaab sawir-qaadis cusub ayaa loo qorsheeyay si kor loogu qaado muuqaalka di/dt iyo dv/dt.Qaab dhismeedka xiriirka ee chip dib ayaa loo dhisay si loo ilaaliyo cidhifka wafer silikoon iyo dusha cathode, waxqabadka korantada ee rogaal celiska ah ayaa si weyn loo horumarin doonaa.

2. Encapsulation

Faa'iidada tignoolajiyada silikon sabbaynaysa ee bilaashka ah waa qallafsanaanta u dhaxaysa silikoon iyo wafer molybdenum oo si weyn loo xakameeyay iyo isticmaalka waferka molybdenum oo hoos u dhacay.Iyadoo flatness of wafer silikon iyo block naxaas ee xirmo aad loogu baahan yahay iyo sidoo kale isbarbardhigga iyo qalafsanaan looga baahan yahay waa ka sarreeyaa tignoolajiyada chip alloying.Horumarka joogtada ah iyo hal-abuurka, RUNAU Electronic waxay ka gudubtay dhammaan caqabadaha farsamada iyo caqabadaha.Tiknoolajiyada sabbaynaysa ee bilaashka ah, thyristor awood sare leh oo leh waxqabad la isku halayn karo iyo xal hufan oo ganacsi ayaa la sameeyay oo la siiyay macaamiisha.Intooda badan waxaa lagu rakibay koronto sare oo la kontaroolo, bilawga jilicsan ee korantada sare, gudbinta korantada HVDC, jiidashada socodka, magdhowga tamarta firfircoon ee firfircoon iyo nidaamka codsiga awooda garaaca wadnaha.

Tilmaamaha farsamada

1. Thyristor wejiga kantaroolay oo leh nooca alloy-ga oo ay soo saartay RUNAU Electronics, baaxadda I_TAVlaga bilaabo 350A ilaa 5580A iyo V_DRM/V_RRMlaga bilaabo 3400V ilaa 8500V.
2. I_GT, V_GTiyo aniga_Hwaa qiyamka tijaabada ah 25 ℃, ilaa si kale loo sheego, dhammaan cabirrada kale waa qiyamka tijaabada ee hoos yimaada T_jm;
3. I²t=I²F SM×tw/2, tw= Sinusoidal kala badh mawjadaha balac ee hadda jira.50Hz, I²t=0.005I²FSM (A²S);
4. At 60Hz: I_FSM(8.3ms)=I_FSM(10ms)×1.066,T_j=T_j;I²t(8.3ms)=I²t (10ms)×0.943,T_j=T_jm
