| 摘 要： | 以制备的纳米改性矿物油为研究样品,对添加纳米颗粒前后矿物绝缘油在100℃、老化35天、每隔7天分别测试油样微水含量、击穿电压、介质损耗及酸值,考核老化前后矿物绝缘油性能。测试结果显示,老化前后不同矿物绝缘油理化电气性能均会出现不同程度劣化,添加有纳米颗粒的矿物油表现出更好的抗氧化性能。

Oxidation Resistance Study of Nano-Particles Modiifed Mineral Transformer Oil |
| |
| Abstract: | The preparative nano-modiifcation mineral oil was taken as the specimen to respectively test oil sample micro-water content, break-down voltage, dielectric loss and acid value for the mineral transformer oil with the temperature of 100℃ and 35 days aging at the intervals of 7 days before and after nano-particles added, to examine the property of the mineral transformer oil before and after aging. The test results show that the physicochemical and electrical properties of different types of mineral transformer oil after aging have different degrees of degradation and deterioration, and the oxidation resistance of nano-particles mineral oil is better. |
