Ein Vakuumkondensator ist ein elektrischer Kondensator, in dem ein Hochvakuum mit einem Gasdruck von etwa 10−7 Torr bzw. 1,33·10−7 mbar als Dielektrikum verwendet wird.
, A vacuum variable capacitor is a variable … A vacuum variable capacitor is a variable capacitor which uses a high vacuum as the dielectric instead of air or other insulating material. This allows for a higher voltage rating than an air dielectric using a smaller total volume. However, many dielectrics have higher breakdown field strengths than vacuum: 60-170 MV/m for teflon, 470-670 MV/m for fused silica and 2000 MV/m for diamond, compared with 20-40 MV/m for vacuum. There are several different designs in vacuum variables. The most common form is inter-meshed concentric cylinders, which are contained within a glass or ceramic vacuum envelope, similar to an electron tube. A metal bellows is used to maintain a vacuum seal while allowing positional control for the moving parts of the capacitor.rol for the moving parts of the capacitor.
