Abstract:
A radio remote explosive detonating system comprising an explosion transmitting line containing an explosive material, a plasma arc coupler comprising a pair of conductors, said coupler receiving an end of said explosion transmitting line positioned in said coupler, said explosion transmitting line, upon said explosive material being ignited, generating a traveling explosion traveling along the length of said explosion transmitting line, a radio transmitter operable to transmit a firing signal, a receiver operable to receive said firing signal, a coupling circuit connected between said receiver and said plasma coupler to apply a high voltage between said conductors in said plasma coupler and generate an arc in response to being triggered, said plasma coupler applying said arc with a cloud of molten metal particles to said explosive material to ignite said explosive material, said receiver triggering said high voltage coupling circuit in response to receiving said firing signal from said transmitter.
