摘要
介绍了电力系统中污闪事故的现状及相应的预防措施,阐述了硅橡胶表面润湿特性及相关模型与硅橡胶表面积污行为的相互作用关系,指出了硅橡胶的润湿性与表面积污行为的的复杂关系。由于硅橡胶表面的憎水性及憎水迁移性,使其具有优异的防污闪性能;而又由于憎水迁移性的存在导致硅橡胶表面的污秽具备"反清洁"能力。文中讲述了国内外学者在自然环境、工频电场及紫外辐照条件下硅橡胶表面润湿特性对积污行为影响的研究进展,并指出了目前这方面研究尚存的问题,展望了硅橡胶表面润湿特性与积污行为的研究方向。
The problem and the preventive measures of the pollution flashover in power system were introduced.The complicated relationship between the wetting property,the relevant model and the pollution accumulation of room temperature vulcanized silicone rubber was also presented.On one hand,the excellent anti-pollution flashover property is attributed to the hydrophobic property and transfer hydrophobic property.On the other hand,the anti-self cleaning is obtained due to the transfer hydrophobic property.Research progress about the effect of wetting property on the pollution accumulation of silicone rubber in different stations was emphasized,such as natural environment,frequency electric field and ultraviolet ray.Moreover,the problem awaiting solution in this area was point out.Finally,the research progress for resolving pollution flashover was put forward completely.
