Icyiciro cyo kugenzura Thyristor (Ubwoko bwo Kureremba Ubuntu)

Ibisobanuro:

Hamwe niterambere ryongerera imbaraga nubushobozi bwibikoresho bihindura, cyane cyane ihererekanyabubasha rya HVDC, ingufu ziva muri unit thyristor zirasabwa kwiyongera uko bikwiye, ibyo bizagabanya ubwinshi bwimikorere ya thyristor mukurikirane hamwe nu murongo uhuza.Ingano yuburemere nuburemere bizagabanuka, ishoramari rito, ndetse nubu ndetse na voltage bizagerwaho byoroshye, imikorere yizewe nagaciro k’ubucuruzi biziyongera cyane.

Tekinoroji ya silicon yubusa ikoreshwa mugukora ingufu nyinshi za thyristor izuzuza ibisabwa murwego rwo hejuru.Muri 2019 Nyakanga, RUNAU Electronics yari imaze gukora 5200V thyristor hamwe na 5 ”chip neza kandi igaha abakiriya basabye umushinga wubushinwa HVDC.

Iriburiro:

1. Chip

Chip isanzwe ya thyristor chip yakozwe na RUNAU Electronics ni tekinoroji ireremba yubusa ikoreshwa.Nibyiza byemewe nkubuhanga bugezweho kandi bukuze bwo gukora ingufu nyinshi za voltage thyristor.Irakoreshwa cyane mubikorwa byo murwego rwisi.

Igikorwa cyo gukwirakwiza cyarushijeho kuba cyiza mu bugari no mu bugari kugira ngo byongere imbaraga za voltage, bigabanye kugabanuka kwa leta kuri voltage, kandi bitezimbere imbarutso & dinamike.Uburyo bushya bwa Photolithography bwashizweho kugirango buzamure di / dt na dv / dt.Imiterere ya chip yongeye kubakwa kugirango irinde inkombe ya silicon wafer na cathode hejuru, imikorere ya voltage ihinduka izanozwa cyane.

2. Encapsulation

Ibyiza bya tekinoroji ya silicon yubusa ni uguhindura hagati ya silicon na molybdenum wafer yabujijwe cyane kandi gukoresha wafer ya molybdenum byagabanutse.Mugihe uburinganire bwa silicon wafer hamwe numuringa wumuringa wa paki birasabwa cyane kimwe nuburinganire hamwe nibisabwa birarenze kuruta kuvanga tekinoroji ya chip.Mugukomeza gutera imbere no guhanga udushya, RUNAU Electronic yari yatsinze ingorane zose za tekiniki n'inzitizi.Ikoranabuhanga rireremba kubuntu, ingufu nyinshi za voltage thyristor hamwe nibikorwa byizewe hamwe nigisubizo cyiza mubucuruzi cyateguwe kandi gihabwa abakiriya.Byinshi muribi byashizwe mumashanyarazi maremare ashobora kugenzurwa, gukurura amashanyarazi menshi, gutangiza amashanyarazi ya HVDC, gukurura moteri, gukurura ingufu za reaction zidasanzwe hamwe na sisitemu yo gukoresha amashanyarazi.

Ibisobanuro bya tekiniki

1. Icyiciro cyagenzuwe na thyristor hamwe na chip yo mu bwoko bwa chip yakozwe na RUNAU Electronics, urwego rwa I._TAVkuva 350A kugeza 5580A na V._DRM/V_RRMkuva 3400V kugeza 8500V.
2. I_GT, V._GTnanjye_Hni ikizamini cyagaciro kuri 25 ℃, keretse bivuzwe ukundi, ibindi bipimo byose nibizamini byagaciro munsi ya T._jm;
3. I²t = I.²F SM × tw / 2, tw = Sinusoidal igice cyumurongo wubugari bwibanze.Kuri 50Hz, I.²t = 0.005I²FSM (A.²S);
4. Kuri 60Hz: I._FSM(8.3ms) = I._FSM(10ms) × 1.066, T._j=T_j;I.²t (8.3ms) = I.²t (10ms) × 0.943, T._j=T_jm
