Abstract

Procedeu pentru mentinerea în functiune a redresoarelor pentru electrolize la caderi de tensiune sau întreruperi de foarte scurta durata, caracterizat prin aceea ca, în scopul reducerii socurilor de curent si anularii necesitatii deconectarii redresorului, utilizeaza un comutator de ploturi cu timp de schimbare a ploturilor mai mic de 2 s care în timpul caderii de tensiune sau al întreruperii de scurta durata nu-si modifica pozitia, la revenirea tensiunii curentului de soc fiind sesizat de un traductor de curent si transmis la circuite de reglaj automat de sarcina care dau comanda pentru diminuarea sarcinii prin selfuri saturabile si comutatorul de ploturi care îsi modifica succesiv pozitia pîna ce curentul de sarcina ia valoarea prestabilita, nepericuloasa pentru diode.
