UNIT FOR ELECTRIC-PULSE BREAKING MATERIALS DOWN Russian patent published in 1994 - IPC

FIELD: electric-pulse units. SUBSTANCE: high-frequency transformer is used as pulse voltage generator; the generator is formed by a set of inductors. As high-voltage electrode the high-voltage cable is used, which has central conductor to be the secondary winding of high-frequency transformer. From low-voltage side the central conductor (secondary winding) of high-frequency transformer is earthed through diode and induction current detector. This pulse voltage generator is used for initiating discharge and forming through conductivity channel in the width of dielectric body to be broken. Break is performed due to power contribution of pulse current generator, connected to the central conductor of high-voltage cable, which is formed by high-voltage power thyristor and capacitor bank. Thyristor is controlled by signal from induction current detector by means of measurement and control unit. EFFECT: improved reliability; improved efficiency. 1 dwg
