RF IMMUNE FIRING CIRCUIT EMPLOYING HIGH-IMPEDANCE LEADS

摘要

High-impedance leads in a firing circuit prevent radiofrequency induced currents from prematurely detonating the electroexplosive device. A capacitor across a serial arrangement of an electroexplosive device and an SCR permits the use of a standard size power source to detonate the (EED) electroexplosive device, notwithstanding the impedance introduced by the interference preventing leads.
