| 摘 要： | 利用辐射电磁场的推迟势方程对空气静电放电的电磁场频谱进行了理论推导,对放电电流峰值和金属小环上的耦合电压峰-峰值进行了测量,使用数字存储示波器记录了放电电流和耦合电压的波形。利用测量结果对静电放电的电磁场频谱进行了理论计算,比较了不同放电电压下耦合电压的幅度谱和功率谱,结果表明:空气静电放电的能量主要集中在直流到2.0 GHz的频段内。

| Abstract: | Derivation for the spectrum expressions of air Electrostatic Discharge(ESD)electromagnetic fields is performed with postponed potential equation of radiated fields.The peak currents of air discharge and peak-peak voltages induced on the loop is measured,and the waveforms of them is recorded by a digital memory oscilloscope.The theoretical calculation for the spectrum of ESD electromagnetic fields is performed with the measured data.The amplitude and the power spectrums for different discharge voltages are compared.It shows that the energy of air ESD is dominated in the frequencies range from DC to 2.0 GHz. |
