Abstract
The invention discloses a sympathetic detonation system. The sympathetic detonation system comprises a detonator outer shell, an initiating explosive, an insulation base, a metal column, a coil, a high-frequency alternating current generator and the like. A high-frequency alternating current is introduced into the coil wound around the detonator outer shell, and the metal column contained in the detonator outer shell is sympathetically heated; as the surface temperature can be rapidly increased through the skin effect, the temperature-sensitive initiating explosive is rapidly detonated to achieve the aim of detonating a detonator; related circuits are not in contact with the initiating explosive at all, and the dangerous condition of a fault explosion caused when static electricity is generated in the transportation or use process is avoided; in addition, the sympathetic detonator system can be suitable for multiple environments; as the requirement of temperature increasing of the metal column for the frequency of the current is special and cannot be influenced by thunderstorm weather and static electricity environments, the influences of surrounding power frequency circuits on the temperature of the metal column are tiny, the application range is wide, the structure is simple, and the cost is low.
