摘要

深入开展35 kV干式空心并联电抗器匝间绝缘材料特性分析研究

对35 kV干式空心电抗器制造材料选择、工艺改进和运维方式具有重要意义。为此

文中研究了不同热老化程度和吸湿对电抗器匝间绝缘材料聚酯薄膜介电特性的影响。通过研究发现:不同老化温度（110、130℃）下

干燥的聚酯薄膜相对介电常数、介质损耗正切值和电导率在老化后期（120 d）都呈现增大的趋势。在较高老化温度下

样品介质损耗正切值增加更加明显。不同老化温度下

吸湿对相对介电常数的影响结果不同。在不同老化程度下

吸湿后的样品其低频下介质损耗正切值仍然呈现增加的趋势

但在高频下其值有所减小。

Abstract

The effects of thermal aging degree and moisture absorption on the dielectric properties of the interturn insulation polyester film were investigated.The results indicated that the relative dielectric constant

the dielectric loss tangent and the electrical conductivity of the dried polyester film increased during the later aging period of 120 days at the aging temperature of 110 and 130℃.The dielectric loss tangent of the sample increased more obviously at higher aging temperature.The effect of moisture absorption on the relative dielectric constant varied at different aging temperature.Under different aging degrees

the dielectric loss tangent of the samples after moisture absorption still showed increasing trend at low frequencies

but it decreased at high frequencies.
