Abstract
The invention concerns a high coulomb transfer switch useful for high current pulse supplies, employing a self-bouncing arc mechanism, wherein two cylindrical electrodes are coaxially arranged and the pathway of current inside the switch is specially designed such that arc current sheet positioned between the coaxially arranged electrodes makes a self bouncing movement in an axial and/or circumferential direction. The self-bouncing arc switch according to the present invention makes it possible to maximize the working area of the electrodes, thereby spread arc energy effectively over the electrodes.
Claims4
A self bouncing arc switch, comprising:
- an inner electrode (1), having two ends, fitted around a central shaft and cylindrically disposed around the central shaft;
- an outer electrode (2), having two ends, arranged to be concentric with said inner electrode and spaced apart from an outer surface of said inner electrode, to form a spacing unit (11) between said inner and outer electrodes;
- one or more arc working gas ports (8) for injecting arc working gas into the spacing unit, such that a switching arc makes electrical contact between said inner and outer electrodes axially or circumferentially, and for evacuating injected arc working gas;
- one or more trigger electrodes (9) each disposed between one end of said inner electrode and one end of said outer electrode, to breakdown the arc working gas and initiate the switching arc;
- an inner conductor (2a), extending outwardly from both ends of said outer electrode, arranged to be spaced apart from an outer surface of said outer electrode;
- an outer conductor (1a), extending outwardly from both ends of said inner electrode to cover the outer surface of said inner conductor with a first insulation layer (5) interposed between said inner and outer conductors;
- and
- one or more terminals (10), leaded at each end of said inner and outer conductors, for connecting said inner and outer conductors to external circuitry.
