DEVICE FOR MEASUREMENT OF OPERATING PARAMETERS OF NON-PRIMARY BLASTING CAP IN BLASTING ELECTRIC DETONATOR

摘要

FIELD: demolition works.SUBSTANCE: invention relates to the field of measurement of parameters of operation of initiators of detonation of explosives during the demolition works, namely electric detonators (ED) comprising a nonprime blasting cap (CD) based on brisant explosives (BE) and standard electric igniter (EV) with rigid or elastic fastening of a resistance bridge. The device for measurement of parameters of operation of the nonprime blasting cap in the blasting electric detonator comprises a muffle for blasting of the electric detonator on a lead plate, a unit of resistance bridge actuation by direct or pulse currents, a response time measuring instrument with starting of time reference point from the moment of actuation, the ionisation sensor for registration of detonation, the ionisation sensor for registration of the moment of operation of electric igniter, unit of registration of signals from sensors and supply of signal to the response time measuring instrument.EFFECT: design of the device allows to provide completely complex measurement of all parameters of operation of the blasting cap of both non-prime, and prime types as a part of the blasting electric detonator, for the first time within one test.3 cl, 1 dwg, 1 tbl
