摘　　要：针对某钝感电起爆器1.5A/2.25W5min不发火的钝感要求和通6A/20ms直流电流可靠发火的要求,通过分析影响电起爆器安全性、发火可靠性及作用时间的影响因素,进行了相关设计及试验。研究表明:合理的散热结构与桥路设计,以及钝感耐高温药剂设计可满足高安全性与可靠发火要求;点火药剂中金属锆粉粒度小于2μm、粘合剂氟橡胶含量为0.5%、压药压力为85MPa时,发火时间精度最佳。该设计为电起爆器类火工品的钝感化研究提供一种新的思路。Aimed at the requirements of non-fire under 1.5A/2.25W5min and fire reliably under 6A/20ms condition,a new insensitive electric initiator was designed and tested in this paper,based on analyzing the factors affecting the safety,fire reliability and function time of the electric initiator.The study show that:when metal zirconium powder is less than 2μm,adhesive fluororubber content is 0.5%,and pressure of charge is 85MPa,the accuracy of ignition time is the best.The design provides a new way for safety and reliability design of insensitive electric initiator.
