DETONATOR Russian patent published in 1999 - IPC

FIELD: detonators. SUBSTANCE: ray, pricked, impact or electric detonator displays in accordance with invention property of thermal safety when heated to above 140 C thanks to employment of thermoelectric heater in amplification charge and heat-resistant explosive in initiator. There are formed clearance between weight of amplification charge and drain holes for release of gases of thermal and chemical decomposition of explosives with overheating. Description gives mathematical relations of basic structural parameters of parts of detonator from point of view of optimization of its operational reliability. EFFECT: enhanced safety in case of unregulated overheating. 1 dwg
