摘要

高压电线中的电晕放电通常被认为是一种损耗,主要表现为功率损耗、绝缘失效和可听噪声。本研究旨在展示CD在电极组合中用作离子推力器(IT)的能力。在每组电极(板对板,球对球,线对板和球对板)上进行单独实验,并使用三种不同的高压(HV)源(霓虹灯变压器(NST), Cockcroft Walton倍增器(CWM)和飞回变压器)来分析和比较它们对离子风推进的影响。通过对已建立的12种高压源电极组合的电场和力学特性数学模型的比较,强调了最佳的几何构型是线-板介质阻挡放电(DBD)。它允许诱导最大速度为3.75 m/s,势半径为176 mm的离子风射流。本文对离子推进、哮喘患者的医疗、电子器件的冷却方法等领域的未来研究和发展也有丰硕的成果。

Analysis on the Propulsion of Ionic Wind During Corona Discharge in Various Electrode Configuration with High Voltage Sources
Corona Discharge (CD) in high tension wires is often considered as loss in the form of power loss, insulation failure and audible noise. The present study aims at showing the ability of CD to be used as Ionic Thruster (IT) in an electrode combination. Individual experiments were conducted on each set of electrodes (plate to plate, sphere to sphere, wire to plate & sphere to plate) with three distinct High Voltage (HV) sources (Neon Sign Transformer (NST), Cockcroft Walton Multiplier (CWM) and fly back transformer) to analyze and compare their effect on the ionic wind propulsion. After comparing the developed mathematical models for electric field and mechanical characteristics of 12 combinations of electrodes with HV sources, it highlight that the best geometrical configuration is the wire to plate Dielectric Barrier Discharge (DBD). It allows to induce ionic wind jet with max velocity of 3.75 m/s with potential radius of 176 mm. This article had also fruitful results for future research and development in the field of ionic propulsion, medical treatment of asthma patients and cooling methods for electronic devices.
