Abstract

Whether the device can ignite depends on its hot spot temperature, which is closely related to the bridge wire temperature. The 50% ignition excitation of the electric explosive device was determined by means of the up-down method and the statistical theory. The relationship between the temperature of the bridge wire and the injection current was determined by the test. Combined with the 50% ignition current of the electric explosive device, the temperature of the bridge wire was obtained when the electric explosive device is ignited. The accurate ignition temperature provides technical support for the safety performance evaluation of the device.
