Zusammenfassung: | The invention relates to an installation with variable coils in stages meant to be used in electric networks of low voltage, to compensate the reactive power. According to the invention, the installation comprises three compensation stages, each with a three-phased coil, a general separating switch, three static breakers, namely breakers with thyristors, switching elements for connecting the stages, stage control circuits, devices for overload and short-circuit protection and signal circuits.
Invenţia se referă la o instalaţie cu bobine variabile în trepte destinată a fi utilizată în reţele electrice de joasă tensiune, pentru compensarea puterii reactive. Instalaţia, conform invenţiei, conţine trei trepte de compensare cu câte o bobină trifazată, un separator general, trei întreruptoare statice, şi anume întreruptoare cu tiristoare, elemente de comutaţie pentru conectarea treptelor, circuite de comandă a treptelor, dispozitive de protecţie la suprasarcină şi scurtcircuit, şi circuite de semnalizare. |
