Abstract

Przedmiotem zgłoszenia jest urządzenie do generacji rotującego pola magnetycznego wysokiej częstotliwości z filtrami elektrycznymi, mające zastosowanie w biomedycynie, w zabiegach radio- i chemioterapii w onkologii, jak i w technice do cieplnej obróbki metali poprzez indukcyjne ich nagrzewanie, gdzie rotujące pole magnetyczne wywołuje w metalach przepływ prądów wirowych, podobnie jak to się dzieje w oscylujących polach magnetycznych (piece indukcyjne). Urządzenie do generacji rotującego pola magnetycznego, składa się z trzech cewek(4, 4', 4") uzwojenia głównego nawiniętych na rdzeniach ferrytowych (2, 2', 2") przylegających z jednej strony do jarzma ferrytowego (1), a z drugiej strony zakończonych nabiegunnikami (3, 3' i 3") tak ukształtowanymi, aby linie sił pola magnetycznego wychodzące z ich powierzchni skupiały się w środkowej części układu (7), przy czym cewki uzwojenia głównego wraz z dołączonymi równolegle do nich kondensatorami (5, 5' i 5") tworzą równoległe obwody rezonansowe, które poprzez szeregowe gałęzie połączonych cewek (6, 6' i 6") kondensatorów (8, 8' i 8") są zasilane z zespołów przełączników (10, 10' i 10") wytwarzających przebiegi prostokątne, sterowane przez blok sterowania (11) i zasilane ze źródła napięcia stałego (9).The subject of the application is a device for generating a high-frequency rotating magnetic field with electric filters, used in biomedicine, in radio- and chemotherapy procedures in oncology, as well as in technology for heat treatment of metals by induction heating, where the rotating magnetic field causes the flow of currents in metals. eddy, similar to what happens in oscillating magnetic fields (induction furnaces). The device for generating a rotating magnetic field consists of three main coils (4, 4 ', 4 ") wound on ferrite cores (2, 2', 2") adjacent on one side to the ferrite yoke (1), and on the other side ending with pole pieces (3, 3 'and 3 ") shaped so that the lines of force of the magnetic field coming from their surfaces are focused in the central part of the system (7), the main winding coils with capacitors (5, 5') connected in parallel to them and 5 ") form parallel resonant circuits which, through the series branches of the connected coils (6, 6 'and 6") of the capacitors (8, 8' and 8 "), are powered from the switch units (10, 10 'and 10") generating the waveforms rectangular, controlled by the control block (11) and powered by a DC voltage source (9).
