| 摘 要： | 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性和时频特性进行了仿真研究.通过与实验研究结果比较得出,针-板电极系统高压电晕辐射场频谱范围大约为250兆赫兹,主要能量集中在100兆赫以下.低频辐射场方向图与偶极子天线的辐射方向图相似,低于100兆赫兹的辐射主要在针电极一侧,高频辐射场方向图极为复杂,并且主要辐射在板电极的后方.电晕放电辐射场的空间分布和时频特性与放电电压、电极的形状以及电晕的发展过程等因素有关,对于不同形式的电晕放电,其辐射场的频域范围不同.

| Abstract: | Simulation research on direction diagram and time-frequency characteristic of the radiation field from high voltage corona between needle and board was studied, and the result indicates that the frequency spectrum of high voltage corona between needle and board is about 250MHz, the main energy focusing in lower than IOOMHz. The direction diagram of low-frequency field is similar to the direction diagram of dipole aerial. Radiation frequency below lOOMHz focuses 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 needle. For different kinds of corona discharge, their frequency domain of radiation field is different. |
