摘要
为了增强云爆战斗部二次起爆引信在爆炸电磁环境中的抗干扰能力,对典型引信电路进行了TVS限幅滤波功能设计,并通过电磁辐射等效试验对其抗电磁干扰效果进行了验证;在此基础上,采用滤波整流抑制、防逆向串扰、光电耦合隔离、接地技术、过压保护等手段对二次起爆引信的起爆电路进行了抗电磁干扰加强设计,并对其抗电磁干扰效果进行了不低于高能云爆战斗部爆炸电磁辐射干扰强度的等效测试。结果表明:该方法在不改变引信结构的前提下,能够将云爆战斗部二次起爆引信的电磁敏感度由V级降至I级。
In order to enhance the anti-electromagnetic interference ability of the secondary detonation fuse of the fuel air explosive(FAE)in explosive electromagnetic environments,a limited amplitude filtering function based on TVS was designed for typical fuze circuits,and its anti-electromagnetic interference effect was verified through electromagnetic radiation equivalent test.On this basis,methods such as filtering rectification suppression,anti-reverse crosstalk,optoelectronic coupling isolation,grounding technology and overvoltage protection were adopted to enhance the anti-electromagnetic interference design of the secondary detonation fuze detonation circuit,and the anti-electromagnetic interference effect was equivalently tested by electromagnetic radiation interference intensity not lower than that of high-energy FAE.The results show that this method can reduce the electromagnetic sensitivity of the secondary detonation fuze of FAE from level V to level I without changing the fuze structure.
