摘要:
爆轰弹丸是喷射气流灭弧防雷装置的重要组成部分,为了既保证该防雷器的灭弧效果,又确保装置在动作后保持完好,对爆轰弹丸的装药方式进行了研究。在介绍了喷射气流灭弧防雷装置的结构和工作原理后,首先对影响爆速的装药直径进行了建模分析,确立了装药直径与爆速之间的关系; 其次考虑装药底盘端部所受冲量对装药量进行了数学分析,确定了装药量与底盘端部所受冲量之间的关系; 最后通过试验确定了爆轰弹丸最优装药比例,得到了该装药比例下喷射气流灭弧防雷装置的灭弧效果。笔者将理论爆炸物理应用于喷射气流灭弧防雷装置,确定了装置的爆轰弹丸装药方式,既保证了装置运行安全又确保了灭弧效果。
Abstract:
The detonation projectile is an important part of the jet gas arc-extinguish lightning protection device. In order to ensure the arc extinguishing effect of the lightning protection device and ensure the device remains intact after the action, the charge mode of the detonation projectile is studied. After introducing the structure and working principle of the jet gas arc-extinguish lightning protection device, the modelling analysis was first performed on the diameter of the charge that affected the detonation velocity, and the relationship between the diameter of the charge and the detonation velocity was established; secondly, the charge amount at the end of the loading tray was mathematically calculated for the charge amount. The relationship between the charge amount and the impulse at the end of the chassis was determined by analysis. Finally, the optimal charge proportion of the detonation projectile was determined through experiments, and the arc extinguishing of the jet gas arc-extinguish lightning protection device was obtained under the charge proportion. In this paper, the theory of explosion physics is applied to the jet gas arc-extinguish and lightning protection device, and the detonation projectile charging method of the device is determined, which not only ensures the safety of the device but also ensures the arc extinguishing effect.
