Gaoya dianqi, 1972 多年来,电力电容器一直是用浸渍液体介质的电容器纸作为介质。被广泛采用的液体介质,主要有矿物油与氯化联苯两种。近十年来,氯化联苯得到了广泛的采用,大有完全取代矿物油的趋势。对大量生产的交流电力电容器来说,使用的介质主要是氯化联苯和电容器纸。 纸介质电容器发展到现代,已经有一套成熟的工艺和相当高的技术经济性能,但由于纸的固有电气损耗和大面积引起的有限介电强度,想再进一步发展重量轻、体积小 ...

MgO对（Sr·K）·TiO3-Bi2O3·TiO2系介质陶瓷微观结构与介电性能的影响
Dianci bileiqi, 1991 研究了在Sr—Bi—K—Ti系统中,添加MgO对微观结构与介电性能的影响。结果表明,添加少量MgO就能使晶粒尺寸明显减小,由此而获得了介电常数高、介质损耗小、抗电强度高、温度特性好的,适合制作高压陶瓷电容器的瓷料。

Gaoya dianqi, 2014 水树枝是交联电缆的主要缺陷,相关研究表明,超低频介质损耗因数与交联电缆水树劣化状态具有较强相关性。笔者通过使用皮尔逊相关系数法,对国际电气电子工程师协会IEEE P4002.9/D9—2010推荐的超低频电压下介损平均值、介损变化率与介损随时间的稳定性3个评价指标,与交联电缆绝缘内部水树枝的密度、长度进行了相关性分析,研究结果对于采用上述指标评估水树枝的生长特性具有较好的理论价值与指导作用。
