voodoo Posted December 5, 2010 Share Posted December 5, 2010 Am cumparat o veioza din obor care are un variator de tensiune cu intrerupator . Problema e ca e aruncat in aer tiristorul (triacul) . Imi puteti spune ce e (tiristor sau triac) si ce indicativ are ? Multumesc !

Spitfire Posted December 5, 2010 Share Posted December 5, 2010 Mai bine ii faceti un variator de la "0", e mai sigur, plus ca montajul e f.f. simplu. Link to comment Share on other sites More sharing options...
miron1947 Posted December 5, 2010 Share Posted December 5, 2010 Imi puteti spune ce e (tiristor sau triac) si ce indicativ are ?Daca functioneaza cu bec de maxim 100W, cu BT169(tiristor). Link to comment Share on other sites More sharing options...

miron1947 Posted December 8, 2010 Share Posted December 8, 2010 Daca vreau un bec mai mare ce tiristor sa pun ?BT151, daca incape. Link to comment Share on other sites More sharing options...
voodoo Posted December 8, 2010 Author Share Posted December 8, 2010 Il inghesui acolo .TIC106 ar merge ?Multumesc frumos ! Link to comment Share on other sites More sharing options...
miron1947 Posted December 8, 2010 Share Posted December 8, 2010 TIC106 ar mergeIncercati, dar sunt diferente de deschidere la curent si tensiune a portii(comparativ cu BT169), dar in cel mai rau caz, nu se mai aprinde lampa, nu stricati nimic.

miron1947 Posted December 28, 2010 Share Posted December 28, 2010 Nu functioneaza schemaDaca ati legat potentiometrul ca in desen,sigur nu regleaza nimic, trebuie legat cursorul, fie impreuna cu un capat al rezistentei, fie doar el si unul dintre capetele rezistentei neconectat.

Spitfire Posted December 28, 2010 Share Posted December 28, 2010 Se intelege ca se pune cum bine zice Dl. Miron1947... sa-l desenam altfel: Si atentie sa nu incurcati A1, A2 si poarta la triac... , A1 este terminalul situat langa poarta. http://en.wikipedia.org/wiki/TRIAC Link to comment Share on other sites More sharing options...

Am legat cursorul si m-am uitat de 10 ori daca nu cumva am incurcat T1 cu T2 .Adica la BT137 nu e T1 T2 G ?E T2 T1 G ? Link to comment Share on other sites More sharing options...
em2006 Posted December 29, 2010 Share Posted December 29, 2010 ...Adica la BT137 nu e T1 T2 G ?..Ba da, T2 e la mijloc. Link to comment Share on other sites More sharing options...
Spitfire Posted December 30, 2010 Share Posted December 30, 2010 T1,T2 sunt simple conventii, tot asa puteau sa se numeasca electrozii aceia "Popescu" si "Ionescu", ideea e sa stiti care din cei doi, Ionescu sau Popescu, e in zona portii...
