Abstract
Invenţia se referă la o instalaţie de comandă şi reglare a curentului de sarcină pentru ondulorul feromagnetic de sudare în curent alternativ, având pe conductorul de nul un capacitor (C) de valoare fixă şi un amplificator magnetic (AM). Curentul din înfăşurarea de sarcină a amplificatorului magnetic (AM) este controlat printr-o buclă de reacţie negativă, în care un transformator de curent (TC) furnizează o tensiune (V') proporţională cu curentul de sarcină (I). Valoarea curentului de sarcină este prescrisă de utilizator dintr-un potenţiometru (P) şi menţinută la valoarea prescrisă prin bucla de reacţie.The invention relates to a load current control and regulation device for ferromagnetic welding on alternating current, having a neutral conductor (C) and a magnetic amplifier (AM). The current in the magnetic winding (AM) winding current is controlled by a negative feedback loop, in which a current transformer (TC) supplies a voltage (V ') proportional to the load current (I). The load current value is prescribed by the user in a potentiometer (P) and maintained at the value prescribed by the reaction loop.
