Miyezo ya 1.IEC idagwiritsidwa ntchito kuzindikiritsa thyristor, diode performance, imakhala ndi magawo khumi, koma ogwiritsa ntchito nthawi zambiri amagwiritsa ntchito khumi kapena kuposerapo, nkhaniyi mwachidule thyristor / diode ya magawo akulu.
2.Average Forward Current IF (AV) (rectifier) / Mean on-state panopa IT (AV) (Thyristor): imatanthauzidwa malinga ndi kutentha kwakuya kwa kutentha kapena kutentha kwa TC THS ikaloledwa kudutsa mu theka la sine la chipangizocho. wave current average.Panthawiyi, kutentha kwa mphambano kwafika pa kutentha kwake kovomerezeka Tjm.LMH Company Product Manual imapereka momwe zinthu zilili panopa molingana ndi kutentha kwa kutentha kwa THS kapena kutentha kwa TC, wogwiritsa ntchito akuyenera kutengera momwe akukhalira, komanso kutentha kuti asankhe mtundu woyenera wa chipangizocho.
3.Forward muzu zikutanthauza lalikulu panopa IF (RMS) (rectifier) / On-state RMS Current IT (RMS) (Thyristor): amatanthauzidwa malinga ndi kutentha lakuya lakuya kapena kutentha mlandu TC THS pamene amaloledwa kuyenda pazipita chipangizo. phindu lamakono.Pogwiritsidwa ntchito, wogwiritsa ntchitoyo awonetsetse kuti muzochitika zilizonse, kutentha kwa RMS komwe kumadutsa pachombo cha chipangizocho sikudutsa muzu womwewo wotanthauza masikweya amtengo wapano.
4.Surge panopa IFSM (rectifier), ITSM (SCR)
Imayimira ntchito muzochitika zapadera, chipangizochi chimatha kupirira nthawi yomweyo kuchuluka kwazinthu zamakono.10ms theka la sine wave yokhala ndi nsonga yomwe LMH imaperekedwa mu bukhu lamankhwala inrush mtengo wapano ndiye kutentha kovomerezeka kwa chipangizocho kuli pansi pa 80% VRRM yomwe imagwiritsidwa ntchito potengera mayeso.Mu moyo wa chipangizo akhoza kupirira inrush panopa malire ndi chiwerengero cha ogwiritsa ntchito ayenera kuyesetsa kupewa mochulukira.
5.Non repetitive peak off-state voltage VDSM / Non repetitive peak reverse voltage VRSM: amatanthauza thyristor kapena rectifier diode ndi kutsekereza boma akhoza kupirira pazipita breakover voteji, nthawi zambiri ndi kugunda kamodzi kuyesa kupewa kuwonongeka kwa chipangizo.Wogwiritsa ntchito poyesa kapena kugwiritsa ntchito, adzaletsedwa kumagetsi ogwiritsidwa ntchito pa chipangizocho, kuti apewe kuwonongeka kwa chipangizocho.
6.Kubwerezabwereza nsonga yamagetsi ya VDRM / Kubwerezabwereza nsonga yamagetsi ya VRRM: kumatanthauza kuti chipangizocho chili m'malo otsekereza, chopanda boma ndi chobwerera kumbuyo chingathe kupirira mphamvu yowonjezereka yobwerezabwereza.Nthawi zambiri chipangizocho sichibwereza voteji 90% chizindikiro (zida zosabwerezabwereza voteji zimatenga 100V zochepa).Ogwiritsa ntchito ayenera kuonetsetsa kuti mulimonse, sayenera kulola chipangizo kupirira voteji weniweni kuposa ake-boma ndi Kubwerezabwereza nsonga reverse voteji.
7. Kubwerezabwereza nsonga zapadziko lapansi (kutayikira) IDRM yamakono / Kubwereza nsonga yapamwamba (kutuluka) IRRM yamakono
Thyristor m'malo otsekereza, kuti athe kupirira nsonga yobwerezabwereza yamagetsi a VDRM ndi VRRM Obwerezabwereza nsonga ya reverse voliyumu, kutsogolo ndi kumbuyo kumayenda kupyola chigawo chapamwamba chakuda chapano.Parameter iyi imalola chipangizocho kugwira ntchito pansi pa kutentha kwakukulu kwa Tjm kuyeza.
8.Peak on-state voltage VTM (SCR) / Peak forward voltage VFM (rectifier)
Imatanthawuza chipangizocho potengera nsonga yaposachedwa ya IFM (rectifier) kapena nsonga yapano ITM (SCR) ndiye nsonga yamagetsi, yomwe imadziwikanso kuti kutsika kwamagetsi.Chizindikirochi chikuwonetsa mwachindunji momwe chipangizocho chatayika panthawi yomwe chipangizocho chatayika, zomwe zimakhudza kuchuluka kwazomwe zidavotera pakadali pano.
Chipangizo pamitengo yosiyanasiyana yapano pansi pa nsonga ya on-state (forward) imatha kuyerekezedwa ndi voltage ndi slope resistor, anati:
VTM = VTO + rT * ITM VFM = VFO + rF * IFM
Thamangani kampani yaku Austria mu bukhu lamankhwala lachitsanzo chilichonse amaperekedwa pazida zokulirapo (zamtsogolo) pachimake voteji ndi voteji pachimake ndi kukana kotsetsereka, zosowa za wogwiritsa ntchito, mutha kupereka voteji yamagetsi ndi kutsetsereka kwa kukana kwake. mtengo.
9.Circuit commutated turn-off time tq (SCR)
Pansi pamikhalidwe yodziwika, mphamvu yayikulu ya thyristor patsogolo imatsika paziro, kuchokera pa zero kuwoloka kuti athe kupirira mphamvu yamagetsi yolemetsa imayikidwa m'malo mwake kuti itembenuze nthawi yocheperako.Nthawi yozimitsa nthawi ya Thyristor imatsimikiziridwa pamikhalidwe yoyezetsa, Thamangani kampani yaku Austrian yopangidwa mwachangu, zida zothamanga kwambiri za thyristor zimapereka nthawi yozimitsa pamtengo uliwonse woyezedwa, sizinafotokozedwe makamaka, mikhalidwe yofananira ndi iyi:
ITM-state pachimake panopa ndi wofanana ndi chipangizo ITAV;
Padziko pano kuchepa kwa chiwerengero di / dt = -20A/μs;
Kukwera kwamagetsi olemera kwambiri dv / dt = 30A/μs;
Reverse voteji VR = 50V;
Kutentha kwapakati Tj = 125 ° C.
Ngati mukufuna zina zomwe mukufuna kugwiritsa ntchito pamayeso anthawi yayitali, mutha kufunsa kwa ife.
10. Mlingo wovuta wa kukwera kwa di / dt pakali pano (SCR)
Amatanthauza thyristor kuchoka kutsekereza boma kupita ku boma, thyristor imatha kupirira kuchuluka kwa kukwera kwapadziko pano.Chipangizochi chingathe kupirira pakali pano Kuchuluka kwa kukwera kwa di / dt chipata choyambitsa vuto ndi kukhudzidwa kwakukulu, kotero timalimbikitsa mwamphamvu kuti ogwiritsa ntchito agwiritse ntchito choyambitsa ntchito, choyambitsa kugunda kwamakono: IG ≥ 10IGT;nthawi yokweza kugunda kwa mtima: tr ≤ 1μs.
10. Mlingo wovuta kwambiri wa kukwera kwamagetsi amtundu wa dv / dt
Pansi pamikhalidwe yodziwika, sikupangitsa kuti thyristor achoke kumtunda kupita ku boma kutembenuza liwiro lovomerezeka la voteji kupita patsogolo.Thamangani buku lazogulitsa zamakampani aku Austrian limapereka mtengo wocheperako pamitundu yonse ya thyristor dv / dt, pomwe wogwiritsa ntchito dv / dt ali ndi zofunikira zapadera, zitha kupangidwa poyitanitsa.
11.Gate choyambitsa voteji VGT / Chipata choyambitsa IGT yamakono
Pansi pa zinthu zina, kupanga thyristor kuzimitsa boma ndi chofunika osachepera chipata voteji ndi chipata panopa.Thyristor idatsegulidwa nthawi yotsegulira, kutayika kotsegulira ndi magwiridwe antchito ena mwakugwiritsa ntchito mphamvu yazizindikiro pachipata chake pakukhudza kwakukulu.Ngati pakugwiritsa ntchito IGT yovuta kwambiri kuti iyambitse thyristor, thyristor sangalole kupeza mawonekedwe abwino otsegulira, nthawi zina ngakhale kuyambitsa kulephera msanga kapena kuwonongeka kwa chipangizocho.Choncho analimbikitsa kuti wosuta ntchito ntchito amphamvu choyambitsa akafuna, choyambitsa kugunda panopa matalikidwe: IG ≥ 10IGT;nthawi yokweza kugunda kwa mtima: tr ≤ 1μs.Kuonetsetsa kuti chipangizocho chikugwira ntchito modalirika, IG iyenera kukhala yayikulu kwambiri kuposa IGT.
12.Crusts resistance Rjc
Amatanthauza chipangizo pansi zinthu zina, chipangizo ikuyenda kuchokera mphambano kuti kutentha kukwera kwaiye pa watt.Kukaniza kwa Crusts kumawonetsa kutentha kwa chipangizocho, chizindikiro ichi chimakhudza kwambiri magwiridwe antchito amtundu wa chipangizocho.Thamangani buku lazogulitsa zamakampani aku Austria pazida zoziziritsa zam'mbali zikuwonetsa kusasunthika kwamphamvu kwa ma module amphamvu a semiconductor, kumapereka kuziziritsa kwambali imodzi kukana kwamafuta.Ogwiritsa ayenera kuzindikira kuti lathyathyathya mbali kutumphuka matenthedwe zotsatira mwachindunji anakhudzidwa ndi zinthu unsembe, kokha malinga ndi Buku kwa analimbikitsa okwera mphamvu unsembe kuonetsetsa kukana matenthedwe chipangizo kukwaniritsa crusts zofunika.
