摘要(Abstract):
通过对SF6设备气体湿度允许值表的解读,指出用露点法测试SF6气体湿度与现场测试的环境温度及测试压力有很大的关系,工作中应避免盲目用仪器直读数据作为反映被测设备的真实值,经分析及现场测试实例论述了温度、压力对测试露点的影响,提出了如何处理由于温度、压力产生影响的测试数据的对策。
Through interpreting the table of allowable values about SF6 equipment gas humidity,the paper proposes that dew point method used to detect SF6 Gas humidity is influenced by the temperature of field-testing and testing of pressure. The data should be considered the influence of the temperature and pressure in the work. After the discussion and analysis of the autoptic example,the paper elaborated that the dew point is influenced by temperature and pressure,and proposed the countermeasure to deal with the testing data.
