Electromagnetic Field Safety Threshold of Electro⁃explosive Devices

为探索电火工品电磁场安全阈值,为电火工品电磁兼容和电磁环境效应研究提供敏感度评价基准,以电火工品电磁‐热耦合模型为基础,采用白光干涉法测试了14号电火工品电磁场响应特征,研究了电火工品电磁场耦合、自身敏感性以及电磁响应三者之间的效应关系,形成了电火工品电磁场安全阈值的试验方法和计算方法,获得了10 kHz~18 GHz频率范围内14号电火工品电磁场安全阈值。结果表明14号电火工品的敏感频率范围为40 MHz~1 GHz。

In order to explore the electromagnetic field safety threshold of electro‐explosive devices(EEDs)and provide a sensitivity evaluation benchmark for the study of electromagnetic compatibility and electromagnetic environmental effects of EEDs,based on the electromagnetic thermal coupling model of EEDs,white light interference method was used to test the electromagnetic field response characteristics of No.14 EED.The effect relationship between electromagnetic field coupling,self sensitivity,and electromagnetic response of EEDs was studied,a test method and calculation method for the electromagnetic field safety threshold of EEDs have been developed,and the electromagnetic field safety threshold of No.14 EED has been obtained within the frequency range of 10 kHz-18 GHz.The results indicate that the sensitive frequency range of No.14 EED is between 40 MHz and 1 GHz.
