随着电力工业高电压、大容量设备的发展,对于充油电气设备绝缘油的质量有了高要求.人们可以通过对绝缘油的分析,来对重要的电力设备进行维护和监督.介绍了如何检测油中的气体含量和成分.为了配合超高压输变电工程用油的分析,参照美国标准 ASTMD881—84的方法并经过改进,研制成功了可测最低含气量达0.05%的仪器.这个仪器具有操作方便、检测精度高、测量时间短的优点.还可以通过微调阀与带有MSQ—500四极质谱计的超高真空机组相连,可以检测含气量的成分.
With the development of high-voltage and high-capacity equipment in the power industry, there is a high demand for the quality of insulating oil for oil-filled electrical equipment, and people can maintain and supervise important electrical equipment by analyzing insulating oil. Testing gas content and composition of the oil.In order to meet the EHV power transmission engineering analysis of oil, with reference to American Standard ASTMD881-84 method and improved to develop a measurable minimum gas content of 0.05% of the instrument.This instrument With the advantages of easy operation, high detection accuracy and short measuring time, it can also be connected to the ultra-high vacuum unit with the MSQ-500 quadrupole mass spectrometer through the fine control valve to detect the gas content.
