ELECTRIC DETONATOR INCLUDING A VARISTOR CAPABLE OF PROVIDING SAFETY BY EXPLODING A BLASTING CAP ONLY AT HIGH TENSION ELECTRICITY SUCH AS ELECTRICAL EXPLODER

摘要

PURPOSE: An electric detonator including a varistor is provided to obtain security in blasting fields which uses high-tension electricity.;CONSTITUTION: An electric detonator comprises a detonator leading wire(10), a varistor(30), and an electric resistance(20). The detonator leading wire is inserted into a detonator tube. The varistor is connected between a leading end of detonator leading wire and a platinum bridge(11) in series. The electric resistance is connected to two wires of detonator leading wire which is inserted into the detonator tube in parallel.;COPYRIGHT KIPO 2012
