Abstract

Inventia se refera la o metoda în curent continuu si un aparat pentru determinarea grupei de conexiuni la transformatoarele trifazate, care consta în amestecarea si/sau schimbarea semnului, semnalelor obtinute în secundarul unui transformator trifazat, pentru a asugura situatia de alimentare a transformatorului în primar. Amestecarea si/sau schimbarea semnului semnalelor se face într-un repartitor alcatuit din sase întrerupatoare cu o iesire comuna, de la care un bloc electronic preia semnalele si le converteste în semnale optice, grupa de conexiuni considerîndu-se determinata, cînd se aprind simultan trei lampi sau numai doua, ordinul grupei citit în dreptul întrerupatorului care a produs unul din cazurile de aprindere aratat fiind par, pentru aprinderea a trei lampi, si impar pentru aprinderea a doua lampi.The invention relates to a DC method and apparatus for determining the group of connections to the three-phase transformers consisting of mixing and / or changing the sign, the signals obtained in the secondary of a three-phase transformer, to assume the transformer supply condition in the primary. Mixing and / or changing the sign of the signals is done in a switch consisting of six switches with a common output, from which an electronic block takes over the signals and converts them into optical signals, the group of connections being considered determined when simultaneously three lamps or only two, the order of the group read next to the switch that produced one of the cases of ignition shown to be lighting up three lamps and odd for the lighting of two lamps.
