Abstract

Przedmiotem zgłoszenia jest przekładnik prądowy wysokiej częstotliwości z funkcją detekcji fazy napięcia zasilającego, posiadający rdzeń magnetyczny (1), na którym nawinięte jest uzwojenie wtórne wysokoczęstotliwościowe (2) oraz uzwojenie wtórne niskoczęstotliwościowe (3), zaś na obu częściach rdzenia magnetycznego (1) wraz z uzwojeniami (2, 3) znajduje się obudowa (4) łączona poprzecznie za pomocą połączeń śrubowych (5) oraz łączona wzdłużnie za pomocą zawiasu (6) i zamknięcia klamrowego (7), a także końce obu uzwojeń wtórnych (2, 3) wyprowadzone są na zewnątrz obudowy (4) za pomocą oddzielnych gniazd współosiowych wielkiej częstotliwości (8.1, 8.2). Charakteryzuje się on tym, że na rdzeniu magnetycznym (1) znajduje się dodatkowe uzwojenie wtórne niskoczęstotliwościowe (3).The subject of the application is a high-frequency current transformer with a supply voltage phase detection function, having a magnetic core (1), on which a high-frequency secondary winding (2) and a low-frequency secondary winding (3) are wound, and on both parts of the magnetic core (1) together with the windings (2, 3) there is a housing (4) connected crosswise by means of screw connections (5) and connected longitudinally by means of a hinge (6) and a clamp closure (7), and also the ends of both secondary windings (2, 3) are led outside the housing (4) by means of separate high-frequency coaxial sockets (8.1, 8.2). It is characterized in that on the magnetic core (1) there is an additional low-frequency secondary winding (3).
