摘要
分析了瓷套式避雷器存在的问题,提出了解决的措施。讨论了采用复合外套避雷器的优点,介绍了电力机车用复合外套避雷器的技术性能及设计中考虑的主要因素及避雷器的热机、盐雾、抗振、污秽、起痕及电蚀试验,通过试验及运行,验证了避雷器的合理性、可靠性及适用性,说明了复合外套避雷器适应电力机车运行工况,同时指出了避雷器安装使用时应注意的问题。
The problem of porcelain housed arrester is analyzed and the measures of resolution are given.The technical characteristic of polymeric housed metal oxide arrester and main consideration in design are introduced;Details of advantage are discussed.Thermo-mechanical precondition test,salt fog test,shock resistance test,tracking and erosion test of MOA are described.Confirmed rationality,reliability and applicability is presented,which proves the applicability of MOA with polymeric housing adapt to working conditions of electric locomotive.Meanwhile,pointed out some problems of precaution are pointed out during installation and usage of MOA.
