Buna ziua tuturor! Am un traf toroidal (gasit prin garaj) cu 10 borne, habar nu am care sunt intrarile si care iesirile, si daca este de 100v sau 220v , am masurat cu multimetru digital si am facut poze la toate bornele intre care exista rezistenta, ma puteti ajuta sa gasesc primarul si secundarul?

In acest caz mai bine rebobinati complet transformatorul cu tensiunile necesare, pentru ca, chiar daca veti afla primarul, aveti slabe sanse sa gasiti un secundar din care sa stoarceti intreaga putere disponibila a transformatorului.

Dar ce la va ganditi sa folositi transformatorul ?

Momentan nu m-am gandit sa il folosesc la nimic , l-am gasit prin garaj si am vrut sa aflu ce tensiuni scoate .Poate pe viitor o sa il folosesc la ceva util.

 

Daca esti dispus sa ma ajuti, am facut niste poze la toate bornele intre care exista rezistenta masurand pe scala de 200 ohmi a multimetrului .

 

Si am alimentat bobina cu rezistenta cea mai mare 162.5 ohmi cu 80v de la un alt traf. si am facut din nou poze la fiecare borne intre care exista tensiune.

 

Mentionez ca toate firele care ies din trafo. au aceleasi sectiune aprox. firului de par !!!

 

Aici am pus poze cu rezistentele intre fiecare borne:

Dupa dimensiuni si rezistentele ohmice masurate de Dvs. eu inclin sa cred ca nu este un transformator de retea.

P,S.

Dacat sa atasati atatea poze greu de manipulat, mai simplu era sa faceti o schita cu bornele pe care sa treceti valorile masurate, astefel erau doar doua imagini, una cu valori rezistive si una cu tensiuni, in genul acesta post-9-0-71195200-1406119823.png

Din acest motiv am recomandat mai sus bobinarea completa a transformatorului, in functie de necesitati.
