Abstract

Un dispositivo para iniciar un detonador eléctrico utilizando un circuito abierto para reducir la ocurrencia de detonaciones accidentales. El dispositivo puede incluir una carcasa del iniciador, como mínimo dos pernos conductores colocados a través de la carcasa del iniciador, espaciados en la carcasa de modo que los pernos conductores queden eléctricamente aislados el uno del otro, y un material de carga iniciadora colocado entre los pernos conductores. Este material puede estar formado por una mezcla de material reactivo y componente metálico. El material de carga iniciadora tiene propiedades eléctricas que proveen resistencia a la conduccion de una corriente eléctrica a fin de mantener una condicion de circuito abierto hasta llegar a un voltaje de ruptura que depende de la cantidad de componente metálico en el material de carga iniciadora, el cual produce subsiguientemente un medio conductor al producirse un arco entre los pernos conductores que surge con voltajes superiores al voltaje de ruptura. Finalmente, sus propiedades eléctricas son tales que el arco eléctrico provee la energía necesaria para formar un plasma a partir del material de carga iniciadora, lo que lleva a la iniciacion del detonador.
