合成绝缘子憎水性迁移机理的研究

Hydrophobicitymigration Mechanism of Composite Insulators

硅橡胶合成绝缘子的优良耐污闪性能源于硅橡胶材料的憎水性的迁移性。本文实验验证了硅橡胶材料中的小分子聚合物是通过挥发作用使绝缘子表面污层获得憎水性的。这一发现使合成绝缘子的憎水性迁移机理更趋于完善。

The excellent properties of silicone rubber composite insulators under polluted condition mainly comes from the hydrophobicitymigration of silicone rubber material. In this paper, it is experimentally proved that the silicone rubber material makes the contaminant layer on the composite insulator hydrophobic through the volatilization of its low molecular weight polymer chains. This discovery perfects the hydrophobicitymigration mechanism of composite insulators.
