摘要

尖端放电是物体尖锐处产生的一种放电现象, 它属于一种电晕放电, 在避雷针、 静电除尘等技术中有着广泛应用。 目前对尖端放电的研究主要集中在放电强度方面, 而对其光谱方面的研究并不多, 研究发现尖端放电在紫外波段具有强烈的辐射。 利用Comsol软件对尖端放电的电离特性进行仿真, 结合数学物理模型分析了放电辐射光谱及辐射强度, 发现其辐射强度随时间的变化先增加后减小, 并可根据N2+的分布强度估算紫外波段的辐射强度。 通过研制一套紫外面阵多光谱成像系统, 对尖端放电进行了三个紫外光谱通道的成像, 实验结果表明, 尖端放电的辐射光谱在240~340 nm波段之间都有分布, 且在315~340 nm之间分布最强。 同时得到尖端放电的紫外辐射强度随着尖端距离的增加而减小, 并与成像积分时间成一定的线性关系。 发现在同一通道, 线性斜率随尖端距离的增加而减小。 通过对尖端放电三个紫外光谱通道的成像码值反演成辐射能量, 得到辐射能量与尖端距离, 尖端电压以及积分时间之间的关系, 验证了尖端放电的数学物理模型, 为深入研究尖端放电的紫外特性提供了有力的支撑依据。

Abstract

The point discharge is a kind of discharge phenomenon which is produced by the sharp point of the object. It belongs to a kind of corona discharge. It has been widely used in lightning rod and electrostatic dust removal technology. At present, the research on point discharge is mainly focused on the discharge intensity, and the research on its spectrum is not much. In this paper, it is found that the point discharge has strong radiation in the ultraviolet band. The ionization characteristics of the tip discharge were simulated by Comsol software, and the discharge spectrum was analyzed by means of mathematical physics model. In addition, the ionization characteristics of the point discharge are simulated by Comsol software. The radiation spectrum and radiation intensity of the discharge are analyzed by the mathematical physical model. The radiation intensity is first increased and then decreased with time, and the UV band can be estimated according to the distribution intensity of N2+ of the radiation intensity. The ultraviolet spectrum of the point discharge was analyzed by three ultraviolet spectra channels. The results show that the emission spectrum of the point discharge is distributed in the 240~340 nm band, 340 nm is the strongest. At the same time, the intensity of ultraviolet radiation of the point discharge decreases with the increase of the tip distance, and has a linear relationship with the imaging integration time. Besides, the linear slope decreases with the tip distance increasing in the same channel. The quantitative relationship between the radiation energy and the tip distance, the tip voltage and the integration time is obtained, and the mathematical model of the point discharge is validated. It is shown that, for the first time, this study provides a solid support for the depth study of UV discharge characteristics of the tip.
