摘要
空气的相对湿度是变化很大的一个气象参数,为了能够更为准确地利用紫外检测技术进行放电的定量研究,需要首先研究相对湿度的变化对检测的影响。利用一种具有定量分析能力的紫外检测装置,通过实验分析电晕放电实际放电量与放电光信号之间的关系。实验结果表明二者之间的拟合关系与实验区域空气的相对湿度没有明显的关系,拟合残差处理后得到的归一化标准差随相对湿度增大而增大,即空气相对湿度对紫外检测过程没有明显的影响,只改变了放电过程本身的波动性。
Relative air humidity is an important fluctuating meteorological parameter.For the sake of quantitive study on discharge by means of UV detection more precisely,impact of relative air humidity on detection needs to be studied first.By use of UV detection with quantitive analysis ability,relationship between real discharge magnitude of corona discharge and optical signal of discharge is experimentally analyzed.The experimental result shows that there is no evident relationship between fitness of the two and relative air humidity around the experiment area,and the normalized standard deviation from residual of fitness increases along with relative humidity,which means that relative air humidity has no evident impact on UV detection and it only changes fluctuations of discharge process.
