Abstract

Prezenta inventie se refera la un dispozitiv de comanda "tot sau nimic" sau "cu faza variabila" a contactoarelor statice cu tiristoare în antiparalel, destinat comutarii circuitelor de curent alternativ, în care separarea galvanica a partii de comanda "de partea de forta" se face pe cale optica. Functionarea dispozitivului de comanda are la baza un releu static cu limitare capacitiva a tensiunii de alimentare si a curentului dispozitivului optic de comanda, care realizeaza separarea galvanica si care comanda grilele tiristoarelor contractorului. Dispozitivul de comanda în regim "tot sau nimic" sau cu "faza variabila" poate fi utilizat la actiunea contactelor statice de curent alternativ mono sau polifazate.The present invention relates to a "totally or nothing" or "variable phase" command device of antiparallel thyristor contactors for switching alternating current circuits, wherein the galvanic separation of the "side of power" make an optic. The operation of the control device is based on a static relay with capacitive limitation of the supply voltage and the current of the optical control device, which performs the galvanic separation and controls the grids of the contractor's thyristors. The "all or nothing" or "variable phase" control device can be used to operate mono or polyphase static AC contacts.
