EXPLOSION CAPACITOR DEVICE Russian patent published in 2015 - IPC F42D1/45 

FIELD: explosion works.

SUBSTANCE: explosion capacitor device contains casing with output terminals for explosion circuit connection, located in casing power source, mains switch with magnetic controlled contact, voltage converter with connected accumulating capacitor, electronic controlled switches of explosion pulse generation, assemblies to monitor resistance of explosion circuit and voltage across accumulating capacitor, and control unit. To initiate the device the removable key is used, it is located in the appropriate socket in the device casing and has resilient element, secured in the key body, and pressing out the socket installed key from the device casing. The key body contains a permanent magnet acting on the magnetically controlled contact of the power key, upon the socket installed removable key pressing to the device casing with force exceeding force of the resilient element, and microprocessor which memory contains program code of the device operation. The microprocessor is made with possibility of connection with the device control unit by means wireless communication channel, and with possibility of contact-free power supply from inductive power supply located in the device casing and connected with control unit.

EFFECT: invention excludes possibility of unauthorized start-up of the device by foreign magnet providing high explosion protection, stabilizes parameters of the explosion pulse in wide range of temperatures, and extends possibility of change of the energetic parameters of the explosion pulse by program change of the detachable key.
