常温空气下外露电极结构的电气体发电实验研究
摘要：为了探究电气体发电基本过程的影响因素和规律，基于电气体发电的基本理论设计了一套简易外露电极结构的电气体高压发电试验装置。基于该装置，以高压空气为工作介质，通过音速喷嘴产生高速气流，利用外露的针尖电极电晕放电产生荷电粒子，研究了气体总压、转换段长度、负载阻值、电晕电压以及电路接法等结构和电气参数对电气体发电电压和功率的影响规律。通过合理配置发电装置参数，获得了相较于电晕电压4.41倍的收集电压或者相较于电晕功率3.53倍的收集功率。研究表明：电势沿着转换段呈抛物线分布；负载阻值越大，收集电压越高；随电晕电压增高，收集功率越大，收集功率和电晕功率之比越小。
Abstract:In order to explore the influencing factors and laws of the basic process of electrogasdynamic power generation, a simple electrogasdaynamic high-voltage power generation test device with exposed electrode structure was designed based on the basic theory of electrogasdaynamic power generation. Based on this device, high-pressure air was used as the working medium, high-speed airflow was generated through sonic nozzles, and charged particles were generated by corona discharge at the exposed needle electrode. The influences of structural and electrical parameters such as total gas pressure, conversion section length, load resistance, applied voltage, and circuit connection on the voltage and power of electrogasdynamic power generation were studied. By reasonably configuring the parameters of the power generation device, a collection voltage of 4.41 times the corona voltage or a collection power of 3.53 times the corona power was obtained. The research shows that the electric potential is parabolically distributed along the conversion section. The greater the load resistance, the higher the collection voltage. As the applied voltage increases, the larger the collection power, the smaller the ratio of the collection power to the corona power.
