摘要

针对复合绝缘子覆冰问题

建立了雨凇环境下复合绝缘子的传热平衡方程

并提出了临界防冰功率密度的计算方法;提出了一种光电混合涂料的制备方法:以共沉淀法制备FeMnCuO

复合金属氧化物粉末作为吸光颜料、以石墨粉作为导电颜料、室温硫化硅橡胶为基料

制备出光电混合涂料;最后对不同比例光电混合型复合绝缘子进行了覆冰试验。计算结果表明复合绝缘子临界防冰功率密度介于23.7～635.6 W/m

之间

环境温度与风速影响显著

防冰用光电混合涂层体积电阻率介于6.38×10

～4.47×10

Ω·cm之间

防冰所需太阳光照强度介于144～1 899 W/m

之间;试验结果说明光电混合型复合绝缘子均有一定的延缓覆冰效果

防冰性能随涂层电阻的减小而提升。

Abstract

In order to solve the problem of composite insulator ice coating

the heat transfer balance model of composite insulators in the glaze weather was established.The calculation method of threshold anti-icing power density was put forward and its influencing factors were summarized.A preparation method of photoelectric hybrid coating was presented:using that precipitation method to prepare the FeMnCuO

complex metal oxide powder as light-absorbing pigment

using graphite as conductive paint and using room temperature vulcanized silicone rubber as base material to make photoelectric hybrid coating.Icing tests

was carried out on composite photoelectric composite insulator finally.Calculations proves that the threshold anti-icing power of composite insulators is between 23.7 and 635.6 W/m

.The ambient temperature and wind speed have a significant influence on it.The volume resistivity of the coating for anti-icing is between 6.38×10

and 4.47×10

Ω·cm.The intensity of solar required for anti-ice is between 144 and 1 899 W/m

.The test result shows that the above insulators all have anti-icing performance.Besides

the anti-icing performance was improved with the decrease of the resistance of the coating.
