摘要
针对影响输变电设备电晕放电强度的温度、湿度、气压以及风4大环境因素,在实验室中运用Coro CAM504型的紫外成像仪对环境因素影响棒—板间隙放电强度进行定量研究,并分析了这4大环境因素对电晕放电强度的影响原因。试验结果表明,棒—板间隙电晕放电强度会随着环境温度的上升而相应增强,且呈现出一定的饱和趋势;随着气压的上升或湿度的增加而减少;风对电晕放电现象存在一定的削弱作用。
Used the CoroCAM504 ultraviolet imager in laboratory, the UV imaging features of rod-plate gap discharge are quantitatively researched, and the four factors such as temperature, humidity, pressure and wind which could influence the test results of the discharge are analyzed. The results showed that corona discharge intensity of rod-plate gap will increase with the rise of temperature and show a degree of saturation trend, reduce with the rise of humidity or pressure. There is a certain weakening effect on the corona discharge phenomenon of the wind.
