Abstract

Inventia se refera la o instasatie pentru verificarea cu tensiune alternativa marita indusa a izolatiei trensformatoarelor de tensiune, care include un dublator magnetic de frecventa alimentata de la reteaua trifazata de 50 Hz cu iesire monofazata de 100 Hz cu pregmatizare în curent continuu ajustabila în functie de valoarea tensiuniii retelei prin intermediul unui redresor comandat adecvat, care alimenteaza un autotransformator monofazat reglabil, la iesirea caruia se conecteaza secundarul transformatorului de încercat, ca si aparate de comanda, semnalizare si protectie.The invention relates to an instability for the induced increased voltage induction voltage voltage transformer isolation including a magnetic frequency duplicator fed from the 50 Hz single phase single phase 100 Hz power supply with adjustable DC in dependence on the value of the network voltage by means of a suitable rectifier rectifier, which supplies an adjustable single-phase autotransformer, at the output of which is connected the secondary of the transformer to be tested, as well as control, signaling and protection devices.
