Abstract
Inventia se refera la energetica, si anume la echipamentele de reglare a unghiului de faza a tensiunilor de intrare si iesire in sistemele de transfer de energie electrica trifazata. Instalatia contine un transformator de excitatie, ce include doua infasurari trifazate de tensiune inalta, prima dintre care este conectata in triunghi, iar a doua este bobinata cu punct mediu si este conectata galvanic cu virfurile triunghiului primei infasurari, un transformator in serie si un bloc de chei electronice de putere. Transformatorul de excitatie este dotat cu trei infasurari trifazate de tensiune joasa, numarul de spire la fiecare fiind acelasi, totodata, sectiunea conductorului infasurarii a doua este mai mare decit sectiunea conductoarelor primei si a treia infasurari, ultima fiind bobinata cu un punct mediu ce o divizeaza in doua parti cu un numar egal de spire. Transformatorul in serie include doua module identice, fiecare fiind dotat cu doua perechi de infasurari trifazate de tensiune inalta si joasa, numarul de spire la fiecare fiind acelasi, iar sectiunea conductoarelor este egala cu sectiunea conductoarelor primei si celei de a treia infasurari de tensiune joasa a transformatorului de excitatie. Blocul de chei electronice de putere include trei perechi de chei electronice, raportul puterilor nominale al carora este . ŕThe invention relates to energy, namely to the equipment for adjusting the phase angle of the input and output voltages in the three-phase electricity transfer systems. The installation contains an excitation transformer, which includes two three-phase high-voltage windings, the first of which is connected in a triangle, and the second is coiled with a midpoint and is galvanically connected with the ends of the triangle of the first winding, a series transformer and a block of electronic power keys. The excitation transformer is equipped with three three-phase low voltage windings, the number of turns at each being the same, at the same time, the conductor section of the second winding is larger than the section of the conductors of the first and third windings, the last being wound with a midpoint dividing it. in two parts with an equal number of coils. The series transformer includes two identical modules, each having two pairs of three-phase high and low voltage windings, the number of turns at each being the same, and the conductor section is equal to the section of the first and third low-voltage windings of the excitation transformer. The electronic power key block includes three pairs of electronic keys, the ratio of whose nominal powers it is. à
