Abstract

DETONADOR PIRO-ELETRâNICO. Detonador (1) piro-eletrônico que compreende um circuito eletrônico (2) de pelo menos de comando de ignição do detonador por envio de uma corrente de ignição em uma ponte eletrotérmica (4), no qual o detonador (1) compreende por outro lado pelo menos um meio de shuntagem (7) elétrico disposto em relação direta com a ponte (4), o meio de shuntagem (7) sendo comandável entre um estado fechado de baixa resistência elétrica do shunt e um estado aberto de grande resistência elétrica do shunt e o circuito eletrônico (2) podendo comandar os ditos estados. O shunt pode ser mono-estável ou bi-estável.
