摘要

摘要: 通过搭建脉冲成形网络放电模块和光谱测试系统，利用Andor SR750光谱仪测量了铜丝电爆炸等离子体在400~500nm范围内的发射光谱。根据热力学平衡理论，采用双谱线相对强度法计算了等离子体的激发温度，并研究了激发温度随时间变化的特性。研究结果表明，铜丝电爆炸产生的稳态等离子体的激发温度约为5 400K。在脉冲放电前期，激发温度变化较大；在放电后期，激发温度较稳定；整个脉冲时间内激发温度差约达800K。

Abstract: A pulse forming network (PFN)discharge module and a spectroscopy system were employed to discuss the electrical explosion of copper wire.The plasma emission spectra were obtained in the wavelength range of 400-500nm by an Andor SR750spectrograph.Based on the thermodynamic equilibrium theory, the arc plasma excitation temperature was calculated by the relative line intensities.And the variation characteristic of the excitation temperature was discussed.The results show that the steady -state plasma excitation temperature by the exploding copper wire is approximately 5400K.The excitation temperature changes obviously in the prophase of the pulse discharge and it is relatively stable at the later stage of the pulse discharge.The excitation temperature difference during the whole pulse time is about 800K.
