Abstract
Przedmiotem zgłoszenia jest zestaw i sposób do określania ciśnienia w czasie rzeczywistym w próżniowych komorach gaszeniowych średniego napięcia. Zestaw posiada światłowody (4.1, 4.2), zamocowane swoimi końcami w próżniowej komorze gaszeniowej (4) podłączonej do układu próżniowego (12), przy czym pomiędzy pierwszymi końcami światłowodów znajduje się badany element (4.3), zaś pierwszy światłowód (4.1) podłączony jest swoim drugim końcem do źródła światła (7), natomiast drugi światłowód (4.2) podłączony jest swoim drugim końcem do analizatora widma optycznego (6), charakteryzuje się tym, że końcowe części światłowodów (4.1, 4.2) ułożone są równolegle, tudzież na końcowej części drugiego światłowodu (4.2) znajduje się siatka Braga (4.4). Sposób polega na tym, że badaną próbkę (4) nagrzewa się za pomocą wiązki światła dostarczanej przez pierwszy światłowód (4.1), do temperatury w do 170°C, typowo 160°C oraz za pomocą drugiego światłowodu (4.2) z siatką Braga (4.4) mierzy się temperaturę, po czym otrzymane wyniki pomiarów temperatury przyporządkowuje się panującemu w próżniowej komorze gaszeniowej ciśnieniu.
