一种工频电场测量装置的湿度影响校正方法和系统
摘要：
本发明提供一种工频电场测量装置的湿度影响校正方法和系统，其将工频电场测量装置以及所用支架一起放置于温度、湿度连续可调的密闭空间的工频电场发生装置内，通过温度恒定时调节湿度获取湿度变化对工频电场测量装置的影响规律，并通过计算得到相应的湿度修正系数，然后根据所述不同温度下的湿度修正系数进行数值拟合，得到对应的修正函数，以及根据所述工频电场测量装置在实际测量中的读数和修正函数进行数值修正。和现有技术相比，本发明的方法和系统克服了现有的大部分湿度敏感型工频测量装置的测量结果随湿度变化较大，难以满足不同湿度下应用的缺陷，获得的测量结果更准确。
摘要（英）：

The invention provides a humidity influence correction method and a system of a power frequency electric field measurement device. The power frequency electric field measurement device and supports used in the power frequency electric field measurement device are placed in a power frequency electric field generating device of an enclosed space which is continuously adjustable in temperature and humidity; an influence law of humidity changes on the power frequency electric field measurement device is obtained by adjusting the humidity when the temperature is constant, and a corresponding humidity correction coefficient is obtained through calculation; numerical fitting is carried out according to humidity correction coefficients at different temperatures to obtain corresponding correction functions; and numerical correction is carried out according to readings and correction functions of the power frequency electric field measuring device in an actual measurement. Compared with the prior art, the humidity influence correction method and the system provided by the invention overcome the defects that most of the power frequency electric field measuring devices have measurement resultslarge in humidity changes, and are difficult to satisfy an application under different humidities; and obtained measurements are more accurate.
