ELECTRIC DETONATING SYSTEM Russian patent published in 2015 - IPC F42B3/10 F42C19/12 

FIELD: electricity.

SUBSTANCE: electric detonating system comprises circuits of electric detonators, each of them consisting of two in series electric detonators and distinguished by the fact that each electric detonator includes external electrode and internal electrode, at that in each circuit of electric detonators their inner electrodes are interconnected and insulated while external electrodes of the first electric detonators in each circuit are jointed and form the first input for connection to power supply source, external electrodes of the second electric detonators in each circuit are jointed and form the second input for connection to power supply source, at that the first and second outputs for connection to power supply source are shunted.

EFFECT: improving safety of use.
