Abstract

Silicone rubber insulation material is widely used for the external insulation of power systems. During the continuous service of a power grid, it will be seriously aged due to the influence of high voltage electric fields and harsh climate environments, which will reduce its insulation performance and service life and cause transmission line failure. How to evaluate the aging performance of silicone rubber insulation materials scientifically and accurately is a hot and difficult issue in the industry. Starting from the composite insulator, which is the most widely used insulating device of silicone rubber insulation materials, this paper expounds the aging mechanism of silicone rubber materials, analyzes the applicability and effectiveness of various existing aging tests and evaluation methods, especially discusses the magnetic resonance detection methods emerging in recent years, and finally summarizes the characterization and evaluation technology of the aging state of silicone rubber insulation materials.

摘要

硅橡胶绝缘材料广泛应用于电力系统的外绝缘。在电网持续运行过程中，由于高压电场和恶劣气候环境的影响，它会严重老化，这将降低其绝缘性能和使用寿命，并导致输电线路故障。如何科学准确地评估硅橡胶绝缘材料的老化性能是该行业的一个热点和难点问题。本文从硅橡胶绝缘材料应用最为广泛的绝缘器件——复合绝缘子入手，阐述了硅橡胶材料的老化机理，分析了各种现有老化试验和评估方法的适用性和有效性，特别讨论了近年来出现的磁共振检测方法，最后总结了硅橡胶绝缘材料老化状态的表征与评估技术。
