METHOD AND APPARATUS FOR IMPROVING THE DISCHARGE REGIME OF AN ELECTRIC ARC PRODUCED BETWEEN TWO ELECTRODES, BY INTERPOSITION OF A HIGH RESISTANCE INSULATING ELEMENT AT LEAST BETWEEN THE ELECTRODES, AND IMPACT GENERATING APPARATUS USING SUCH A METHOD OR DEVICE , IN PARTICULAR FOR HYDRAULIC LITHOTRYPSY

摘要

The invention relates to a method and a device for improving the discharge regime of an electric arc produced between two electrodes. This device is characterized in that it comprises means 30 for increasing the resistance to the passage of the electric arc A at least between the electrodes 12, 14, preferably constituted by an insulating element 32 which is preferably of a substantially spherical shape. / P P Thanks to the invention, an arc discharge regime is obtained which is of the critical damped type. This method and device are preferably used in shock wave generation apparatus for hydraulic lithotrypsia. / P
