摘要
针对电热化学炮研究中所遇到的电磁干扰问题,分析了电磁环境影响时序控制系统工作可靠性的主要因素及途径.对电磁干扰信号进行了频谱分析,提出了利用浮地屏蔽法解决控制系统抗干扰的技术措施,并在储能300kJ的脉冲功率源中进行了多路放电实验.有效地提高了时序控制系统的抗干扰能力。
Because the transient electromagnetic fields provided by discharge current cause electromagnetic interference to sequential controller of mutil moudle PFN in a ETC environment, this paper analyses main factors that influence reliability of control system and studies frequency response characteristics of interference signal and electrical circuit. This paper puts forward insulating and shielding technology and enhances reliability of control system effectively. The experiments of 30 kJ pulsed power electrical circuit indicate that the working stasility should be improred effectively.
