Circuit de comanda Tiristor

Recommended Posts

Buna ziua am niste circuite de comanda pentru tiristoare(fabricate de ELECTRO TEHNICA) dar nu stiu schema interna sau ce contine, cred ca e cu TUJ dar nu sunt sigur inainte de a strica unul sa vad ce are inauntru apelez la voi!!!!!!

 

Prin rasina se vede cat de cat un tranzistor cu capsula to126(ca pentru bd140) ceva rezistenta cu pelicula de carbon.

 

Am facut si o schema cum a fost legat la tiristor

Nu e modulul respectiv pentru ca intre picorul 1+2 nu am nimic nici la 200M Ohm si picorul 2+3 si 4+5 sunt unite pe cablaj se vede prin rasina (am verificat 0Ohm!)Am vazut mai multe piese prin rasina printre altele un tranzistor cu capsula de to126+ceva rezistente o sa stiu mai mult cand desfac daca pot :sparge:
