Saurin Canja Thyristor

Bayani:

Saurin sauya thyristor, tare da tsari iri ɗaya da alama na sarrafa lokaci na thyristor, yayin da mafi kyawun halaye masu mahimmanci, musamman halaye masu ƙarfi ana buƙata ta babban mitar aikace-aikacen gyarawa, sara, inverter da da'irar juyawa mitar.Ma'auni masu ƙarfi na thyristor mai sauri sune saurin kunnawa da saurin faɗaɗa kunnawa, ƙarancin cajin dawo da baya, da ɗan gajeren lokacin kashewa, babban ƙimar hauhawar halin yanzu (di/dt) da ƙimar mahimmanci Tashin wutar lantarki ta kashe-jihar (dv/dt).Ƙididdigar halin yanzu na thyristor mai sauri a cikin mitar da aka ƙididdigewa baya raguwa ko raguwa kaɗan lokacin da mitar ta ƙaru.

An gabatar da ma'aunin masana'anta na thyristor mai saurin canzawa da fasahar sarrafa kayan lantarki na RUNAU Electronics daga Amurka tun daga 1980s, a matsayin majagaba na masana'antar thyristor a kasar Sin, ƙungiyar fasaha ta RUNAU ta sami ingantaccen ilimi da ƙwarewar masana'antu sama da shekaru 30.A kan asali na gargajiya masana'antu tsari, da gwaninta technicians na RUNAU Electronics sun ɓullo da art-of-jihar fasahar a Manufacturing thyristor tare da fa'idar fasali na Turai kayayyakin, da inganci da kuma aiki da ake inganta ƙwarai, mafi girma nasara samu a cikin ikon lantarki aikace-aikace, kuma an ƙirƙiri ƙarin ƙimar ga abokan tarayya.

Gabatarwa:

1. Chip

Thyristor guntu da RUNAU Electronics ya ƙera ana amfani da fasahar haɗaɗɗen haɗakarwa.An siyar da siliki da wafer molybdenum don haɗawa ta hanyar aluminium mai tsafta (99.999%) a ƙarƙashin babban vacuum da yanayin zafin jiki.Gudanar da halayen sintering shine babban abin da zai shafi ingancin thyristor.Sanin-yadda na RUNAU Electronics ban da sarrafa gami junction zurfin, surface flatness, gami rami kazalika da cikakken yaduwa basira, zobe da'irar juna, musamman kofa tsarin.Hakanan an yi amfani da sarrafawa na musamman don rage rayuwar mai ɗaukar na'urar, ta yadda saurin sake haɗawa na cikin gida ya haɓaka sosai, an rage cajin dawo da na'urar, kuma saurin sauyawa ya inganta saboda haka.An yi amfani da irin waɗannan ma'auni don haɓaka halayen sauyawa cikin sauri, halayen kan-jihar, da haɓakar kadarorin yanzu.Ayyukan aiki da gudanarwa na thyristor abin dogara ne da inganci.

2. Encapsulation

Ta hanyar tsananin sarrafa faɗuwa da daidaiton molybdenum wafer da fakitin waje, guntu da wafer molybdenum za a haɗa su tare da fakitin waje tam kuma gaba ɗaya.Irin wannan zai inganta juriya na hawan halin yanzu da babban gajeriyar da'irar halin yanzu.Kuma an yi amfani da ma'aunin fasahar evaporation na lantarki don ƙirƙirar fim mai kauri na aluminum akan saman siliki wafer, kuma rufin ruthenium wanda aka sanya akan molybdenum surface zai haɓaka juriya na zafin thermal sosai, lokacin rayuwar aiki na saurin canza thyristor za a ƙara sosai.

Ƙayyadaddun fasaha

1. Saurin sauya thyristor tare da guntu nau'in alloy wanda RUNAU Electronics ke ƙera, kewayon I_TAVdaga 200A zuwa 4000A da V_DRM/V_RRMdaga 1200 zuwa 4500 V.
2. I_GT, V_GTkuma I_Hsune ƙimar gwajin a 25 ℃, sai dai in an faɗi in ba haka ba, duk sauran sigogi sune ƙimar gwajin ƙarƙashin T_jm;
3. I²t=I²F SM ×tw/2, tw= Sinusoidal rabin kalaman nisa na yanzu.A 50Hz, I²t=0.005I²FSM (A²S);
4. a 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
