摘要:
绝缘子在实际使用过程中,不仅会随着使用年限的增加而产生老化,环境温度的突然变化也会对绝缘子的憎水性、表面硬度产生影响,在电力系统中,许多不明闪络往往发生在外界环境发生突变的时候,为了更好的研究环境温度短时间内剧烈变化对复合绝缘子的影响,文中对复合绝缘子样品进行了温度循环试验,以模拟环境温度短时间内剧烈变化,并研究了复合绝缘子在温度循环试验条件下憎水性及表面硬度的变化。结果表明,短时间的温度突变能够影响绝缘子表面憎水性与硬度,并且随着温度循环次数的增加,绝缘子表面的憎水性会进一步下降,表面硬化更加明显,二者表现出一定的相关性。
Abstract:
In actual use, the insulators will not only age with the increase in service life, but the sudden changes in the environment will also affect the hydrophobicity and surface hardness of the insulators. In the power system, many unidentified flashover often occur when the external environment occurs abruptly. In order to better simulate the influence of the violent changes of the ambient temperature on the composite insulators, this paper is the author of this paper. The temperature cycling test of insulator samples was carried out, and the change of hydrophobicity and surface hardness of composite insulators under the condition of temperature cycling test was studied. The results show that the short time temperature mutation can affect the surface hydrophobicity and hardness of the insulator, and the hydrophobicity of the insulator surface will be further reduced and the surface hardening is more obvious with the increase of temperature cycle times, which shows that there is a certain correlation between the two.
