摘要

作者报告了进行的调查，以确定PD参数和矿物基油部分放电产生的溶解气体之间的关系。矿物基油的PD活性取决于许多参数，包括测试容器填充和测试电压切换之间的停留时间以及电压大小对PD活性的影响。在气态行为方面，几种碳氢化合物与积分PD参数呈线性(递增)关系。相比之下，氧的用量随着PD负荷的增加而减少。气体比的计算表明，氢和甲烷的关系是矿物油中PD活性的敏感指标。

The correlation between partial discharges (PD) and gassing in insulating liquids

The authors report on investigations performed to determine the relationship between PD parameters and the dissolved gas generated by partial discharges in mineral-based oil. The PD activity of mineral-based oil is shown to depend upon many parameters, including the influence of the standing time between the filling of the test vessel and the switching of the test voltage as well as the voltage's magnitude on the PD activity. Regarding the gassing behavior, several hydrocarbons show a linear (increasing) dependence upon the integral PD parameters. By contrast the amount of oxygen decreases with increasing PD loading. Calculation of gas ratios indicates that the relation between hydrogen and methane is a sensitive indicator of PD activity in mineral-based oil.<>
