Abstract

Przedmiotem zgłoszenia jest przekładnik prądowy wysokiej częstotliwości do pomiarów wyładowań niezupełnych w głowicach kablowych, posiadający rdzeń główny (1) zakończony nagwintowanymi otworami (2), na którym osadzony jest rdzeń magnetyczny (3), na którym nawinięte jest uzwojenie wtórne (4) oraz rdzenie (1, 3) wraz z uzwojeniem wtórnym (4) umieszone są wewnątrz odlewu (5), zaś na odlewie (5) pomiędzy końcami rdzenia głównego (1) umieszczone są klosze (6) oraz końce uzwojenia wtórnego (4) wyprowadzone są na zewnątrz odlewu (5) za pomocą gniazda współosiowego wielkiej częstotliwości (7). Charakteryzuje się on tym, że rdzeń magnetyczny (3) zabudowany jest wewnątrz hermetycznego odlewu (5) z silikonu z kloszami (6) tudzież rdzeń magnetyczny (3) osadzony jest na rdzeniu głównym (1).The subject of the application is a high-frequency current transformer for measuring partial discharges in cable heads, having a main core (1) terminated with threaded holes (2), on which a magnetic core (3) is mounted, on which a secondary winding (4) is wound and cores (1, 3) together with the secondary winding (4) are placed inside a casting (5), while on the casting (5) between the ends of the main core (1) there are sheds (6) and the ends of the secondary winding (4) are led outside the casting (5) by means of a high-frequency coaxial socket (7). It is characterized in that the magnetic core (3) is built inside a hermetic casting (5) made of silicone with sheds (6) and the magnetic core (3) is mounted on the main core (1).
