Zusammenfassung: | The invention relates to the field of electric power engineering and can be used to control active power fluxes in transport and distribution electrical network branches.The three-phase transformer phase regulator comprises a three-core magnetic circuit, on each core of which are located one primary (1), (2), (3) and one secondary (4), (5), (6) winding with the same number of turns, and one regulating winding (7), (8) and (9) with an under load switching mechanism with grounded moving contacts (10, 11, 12). The ends of the primary windings (1), (2) and (3) are connected to the ends of the secondary windings (4), (5), (6) and to the starts of the regulating windings (7), (8), (9) via a double two-position three-phase switch (16) for changing the direction of regulation of the phase shift angle.
Invenţia se referă la electroenergetică, şi poate fi utilizată pentru dirijarea fluxurilor de putere activă în ramurile reţelelor electrice de transport şi distribuţie.Regulatorul de fază trifazat cu transformator conţine un circuit magnetic cu trei miezuri, pe fiecare miez al căruia sunt amplasate câte o înfăşurare primară (1), (2), (3) şi una secundară (4), (5), (6) cu acelaşi număr de spire, precum şi câte o înfăşurare de reglare (7), (8), (9) cu un mecanism de comutare sub sarcină cu contacte mobile (10), (11), (12) legate la pământ. Sfârşiturile înfăşurărilor primare (1), (2), (3) sunt conectate la sfârşiturileînfăşurărilor secundare (4), (5), (6) şi la începuturileînfăşurărilor de reglare (7), (8), (9) printr-un comutator (16) trifazat dublat cu două poziţii pentru schimbarea direcţiei de reglare a unghiului decalajului de fază.
Изобретение относится к электроэнергетике и может быть использовано для управления потоками активной мощности в ветвях транспортных и распределительных электрических сетей.Трехфазный трансформаторный фазорегулятор содержит трехстержневой магнитопровод, на каждом стержне которого расположены по одной первичной (1), (2), (3) и вторичной (4), (5), (6) обмотке с одинаковым числом витков, а также по одной регулировочной обмотке (7), (8), (9) с механизмом переключения под нагрузкой с заземленными подвижными контактами (10, 11, 12). Концы первичных обмоток (1), (2), (3) подключены к концам вторичных обмоток (4), (5), (6) и к началам регулировочных обмоток (7), (8), (9) через сдвоенный двухпозиционный трехфазный переключатель (16) для изменения направления регулирования угла фазового сдвига. |
