I-Phase Control Thyristor (Uhlobo Oluntantayo Lwamahhala)

Incazelo:

Ngokuthuthuka kwamandla akhulayo kanye nomthamo wemishini yokuguqula, ikakhulukazi ukudluliswa kwe-HVDC, amandla okukhipha amandla eyunithi ye-thyristor acelwa ukuthi akhuphuke ngokufanele, lokho kuzonciphisa inani lokufakwa kwe-thyristor ochungechungeni kanye nesekethe yokuxhuma okuhambisanayo.Usayizi wedivayisi nesisindo kuzoncishiswa, ukutshalwa kwezimali okuphansi, ngisho namanje ngisho ne-voltage kuzobonakala kalula, ukusebenza okuthembekile kanye nenani lezentengiselwano kuzokwenyuka kakhulu.

Ubuchwepheshe be-silicon entantayo bamahhala obusetshenziswa ukwenza amandla aphezulu we-thyristor yamanje buzokwanelisa imfuneko yohlelo lokusebenza olusezingeni eliphezulu.Futhi ngo-2019 July, i-RUNAU Electronics yayithuthukise i-5200V thyristor ene-chip engu-5” ngempumelelo futhi yanikezwa ikhasimende elifake isicelo kuphrojekthi yase-China HVDC.

Isingeniso:

1. I-chip

I-chip esezingeni eliphakeme ye-thyristor ekhiqizwe yi-RUNAU Electronics isetshenziswa ubuchwepheshe obuntantayo bamahhala.Iwubuchwepheshe obaziwa njengobuchwepheshe bakamuva nobuvuthiwe bokukhiqiza i-thyristor yamandla aphezulu wamandla aphezulu.Isetshenziswa kabanzi ngabakhiqizi abasezingeni eliphezulu kakhulu emhlabeni.

Inqubo yokusabalalisa iye yathuthukiswa ngokuminyana nobubanzi ukuze kukhuliswe ukumelana nogesi, kwehliswe ukwehla kwamandla kagesi akusimo sezwe, futhi kuthuthukiswe i-trigger nezici eziguqukayo.Iphethini entsha ye-photolithography yakhelwe ukuthuthukisa isici se-di/dt ne-dv/dt.Isakhiwo sokuxhumana se-chip sakhiwa kabusha ukuze kuvikelwe unqenqema lwe-silicon wafer kanye ne-cathode surface, ukusebenza kwe-voltage ehlehlayo kuzothuthukiswa kakhulu.

2. Encapsulation

Inzuzo yobuchwepheshe be-silicon entantayo yamahhala ukuwohloka phakathi kwe-silicon ne-molybdenum wafer kuvinjelwe kakhulu futhi ukusetshenziswa kwe-molybdenum wafer kuncishisiwe.Ngenkathi ukucaba kwe-silicon wafer kanye nebhulokhi yethusi yephakeji kudingekile kakhulu kanye nemfuneko yokufana nokumahhadla kuphezulu kunobuchwepheshe be-alloying chip.Ngokuthuthuka okuqhubekayo kanye nokuqanjwa okusha, i-RUNAU Electronic isinqobe bonke ubunzima bezobuchwepheshe nezithiyo.Ubuchwepheshe obuntantayo bamahhala, amandla aphezulu we-thyristor yamandla aphezulu nokusebenza okuthembekile kanye nesixazululo esiphumelelayo sokuhweba kwathuthukiswa futhi kwanikezwa amaklayenti.Eziningi zazo zifakwe kusilungisi esilawulekayo samandla aphezulu, isiqalisi esithambile sikagesi ophezulu, ukudluliswa kwamandla e-HVDC, ukudonsa kwesitimela, isinxephezelo samandla asebenzayo aguqukayo kanye nohlelo lokusebenzisa amandla e-pulse.

Ukucaciswa kobuchwepheshe

1. I-thyristor elawulwa yisigaba ene-alloy type chip ekhiqizwe yi-RUNAU Electronics, uhla lwe-I_I-TAVkusuka ku-350A kuya ku-5580A kanye ne-V_I-DRM/V_I-RRMkusuka ku-3400V kuya ku-8500V.
2. I_GT, V_GTnami_Hamanani okuhlola aku-25℃, ngaphandle uma kushiwo ngenye indlela, wonke amanye amapharamitha amanani okuhlola ngaphansi kuka-T._jm;
3. I²t=ngi²F SM×tw/2,tw= Ububanzi besisekelo segagasi le-Sinusoidal uhhafu wamanje.Ku-50Hz, I²t=0.005I²I-FSM(A²S);
4. ngo 60Hz:I_I-FSM(8.3ms)=I_I-FSM(10ms)×1.066,T_j=T_j;I²t(8.3ms)=I²t(10ms)×0.943,T_j=T_jm
