Research on Real Electrostatic Sensitivity Test for Conductive-powder Electroexplosive Device

摘要

This paper briefly introduces the method of testing the real electrostatic sensitivity of conductive-powder EED and gives the data processing method in terms of that the critical ignition energy conforms to logarithmic normal distribution. On basis of that, we have researched the electrostatic sensitivity of 105 electric blasting cap and have determined the confidence interval of its minimum ignition energy is (88.3approx131.8) muJ.
