| 摘 要： | 电晕放电是静电放电的一种特殊形式。在分析电晕放电特性的基础上,对针-板电极系统高压电晕辐射场方向特性进行了仿真研究。通过实验与仿真得出:针-板电极系统高压电晕辐射场频谱范围大约为10~200MHz,能量主要集中在80 MHz以下。80 MHz以下辐射场方向图与偶极子天线的辐射方向图相似,低于100 MHz的辐射主要在针电极一侧,而高于100 MHz以上的辐射场方向图极为复杂,其主要辐射在板电极的后方。电晕放电辐射场的空间分布与放电电压、电极的形状以及电晕的发展过程等因素有关,对于电晕放电的不同发展阶段,其辐射场的频域范围也不同。

| Abstract: | The radiation field of high voltage corona between needle and board is studied in this paper,and the result indicates that the frequency spectrum of high voltage corona between needle and board is about 200 MHz,the main energy focusing in lower than 80 MHz.The direction diagram of low-frequency field is similar to the direction diagram of dipole aerial.Radiation frequency below 100 MHz focus on the side of needle,and the direction diagram of high-frequency radiation filed is very complicated as well as the main radiation is behind the board.For different evolution phase of corona discharge,their frequency domain of radiation field is different. |
