SF₆气密封橡胶材料气体渗透特性研究

Gaoya dianqi, 2019
橡胶密封材料的性能对电气设备运行可靠性有重要的影响。文中通过老化试验,研究三元乙丙橡胶、丁腈橡胶、氟橡胶、氟硅橡胶和丙烯酸酯橡胶的透气性差异及变化特性,并利用模拟橡胶在使用过程中的气封环境装置,比较橡胶老化后的气密性。结果表明:丁腈橡胶、氟橡胶、氟硅橡胶、三元乙丙橡胶和丙烯酸酯对SF6气体透气系数不同,丁腈橡胶透气系数最小,氟硅橡胶最大;丁腈橡胶、氟橡胶、氟硅橡胶、三元乙丙橡胶和丙烯酸酯橡胶热空气老化后透气系数变化有较大差异,其中丁腈橡胶、氟硅橡胶、三元乙丙橡胶和氟橡胶的透气系数老化后变小 ...

变压器油色谱在线监测数据有效性评估

Gaoya dianqi, 2018
变压器油色谱在线监测数据质量是影响状态评估准确性的重要因素,为评估在线监测数据的有效性,根据变压器油色谱特点,分别以H2、总烃和CO作为特征气体,采用Fast-MCD稳健分析方法进行异常值检测;定义了在线监测单一特征气体数据有效性评估指标和加权油色谱在线监测系统数据有效性评估指标。通过对某电网500 kV变压器在线监测数据样本统计分析,对常见的三种油色谱在线监测系统的数据有效性进行了对比评估。
