FIELD: physics.
SUBSTANCE: method of extinguishing a thermionic arc with metal electrodes during electric explosion of wire and preventing melting and evaporation of the metal electrodes involves putting the electrodes in polymer covers. When the temperature in the discharge increases, the polymer melts and covers bare areas of the electrodes with a non-conducting film, which breaks the discharge electric circuit, thereby stopping discharge.
EFFECT: extinguishing a thermionic arc with metal electrodes during electric explosion of wire, preventing melting and evaporation of electrodes.
