酸值对天然酯绝缘油介电性能的影响
Effect of dielectric properties of natural ester insulating oil by acid value
摘要
Abstract
Natural ester insulating oil containing different acid value were prepared by the method of extraction.The temperature dielectric spectroscopy and the frequency dielectric spectroscopy of natural ester insulating oil containing different acid value were tested.The results showed that when the testing temperature covered the range of 30～90 ℃,the relative permittivity was decreased with the increasing of the temperature,the dielectric loss factor was increased with the increasing of the temperature.When the testing frequency covered the range of 10-2～107 Hz,the relative permittivity and the dielectric loss factor of natural ester insulating oil were decreased with the increasing of the frequency.When the testing temperature or the testing was is equal,the higher the acid value of natural ester insulating oil,the relative dielectric and the dielectric loss factor of natural ester insulating oil were the greater.关键词
