LOW-INDUCTION HIGH-VOLTAGE VACUUM TRANSITION Russian patent published in 2012 - IPC H02N11/00 

FIELD: electric engineering.

SUBSTANCE: low induction high voltage vacuum transition relates to high-voltage pulse equipment, namely to the equipment capable of creating and applying strong pulse magnetic fields and may be used for isolating electrodes during electro magnetic energy transfer from the powerful current source to plazma or dynamic load. The subject of invention: as compared to the known low induction high voltage vacuum transition contains coaxially placed anode and cathode separated by the main thin-walled isolator and transition isolator where dielectric-vacuum separation takes place on its surface. At the same time, the vacuum section of anode surface close to the transitional isolator is located at the angle of equipotential lines to the surface ensuring tilting of equipotential lines to the surface of transitional isolator at less 45°. The novelty of invention is that the main and transitional isolators are separated with a gap filled in with higher dielectric permeability than dielectric permeability of contacting structural elements materials. Besides, the ends of isolators are embedded into ring-shape groove which their sharp edges being made round to ensure reduced electric field in the contacting points metal-dielectric-vacuum.

EFFECT: even distribution of electric field intensity along isolators' surface and minimum intensity in points of their contact with electrodes.
