ELECTRICAL IGNITER WITH PROTECTION AGAINST STATIC ELECTRICITY DISCHARGES Russian patent published in 2010 - IPC F42B3/12 F42C19/12 

FIELD: electricity.

SUBSTANCE: electrical igniter (EI) with protection against static electricity discharges refers to electrical initiation facilities and can be used in pyrocartridge structure development intended for using for instance in opening, separation, disengagement, etc. systems. EI includes body where small socket with electric terminals and resistance bridge, header with igniting charge and main charge are installed. The igniting charge is made of compound based on organic high explosive agent and zirconium powder and is separated from main charge by metal cap. In this structure, relative density of igniting charge is less than 0.65 and the main charge is made of high explosive agent not sensitive to static electricity discharge.

EFFECT: simplification of device structure.
