项目摘要
The summary of the research results of the research project during 1992-1993 is as follows.For the purpose of obtaining the electric field, magnetic field and electromagnetic field caused by the natural lightning, the collected data on the lightning parameters especially for the winter lightning in the northern seashore districts of the Japan Sea side of the main island were analyzed and summarized. Furthermore, analysis of the location of the lightning by using the magnetic field was carried out. Moreover, the induced overvoltages on the distribution line due to lightning was analyzed. Calculated results on the overvoltages was in very good agreement with that obtained by experimental results.With regard to the magnetic field of the commercial frequency, the measurement was carried out using a novel type of device developed by the authors. The measurement on the magnetic field around a cubicle type substation was carried out. The reasonable results was obtained which were served for detailed analysis. Furthermore, the magnetic field of the ELF frequency band around a GIL model with and infinite length was analyzed numerically and the detailed distribution of the magnetic field has been clarified.With regard to the corona discharge from the electric power apparatus, it has been clarified by the experimental investigation in the laboratory using a needle to plane electrode at atmospheric pressure that the increase of the discharge point causes the increase of the interference due to impulsive noise. Also the influence of corona discharge and corona noise in VHF band were investigated in detail. Together with this research, an application using the Walsh function in the field of corona noise was made at the first time. As the result of this investigation, quantitative explanation has been added for the first time to the qualitative understanding which were usually made before.
1992-1993年期间,为了获得天然闪电引起的电场、磁场和电磁场,对收集到的日本本岛日本海一侧北方海滨地区的闪电参数,特别是冬季闪电的闪电参数进行了分析和总结。此外,利用磁场对闪电的位置进行了分析。此外,还分析了雷电在配电线路上产生的感应过电压。过电压的计算结果与实验结果吻合很好。对于工频磁场,采用作者研制的一种新型装置进行了测量。对某箱式变电站周围的磁场进行了测量。得到了合理的计算结果,为进一步的分析提供了依据.对无限长GIL模型周围极低频磁场进行了数值分析,得到了极低频磁场的详细分布。通过在实验室中在大气压下使用针对平面电极的实验研究已经阐明,脉冲噪声引起的干扰增加。详细研究了甚高频电晕放电和电晕噪声的影响。结合本研究,首次将沃尔什函数应用于电晕噪声领域。作为这一调查的结果,定量解释已被添加到第一次,以定性的理解,通常是以前。
