摘要
Abstract
A rigid detonator fusehead and a LGS-2A millisecond detonator tester were chosen to study the effect of current intensity (1. 0-4. 0 A) on the ignition time of hot bridge-wire electric fusehead. Experimental results show that the ignition time of hot bridge-wire electric fusehead decreases with the increase of current intensity at first, and then tends to be stable. Meanwhile, the ignition time difference for different detonator fuseheads at same current intensity reduces gradu-ally. The stable ignition time of electric fusehead is confirmed as 0. 7 ms.关键词
