Abstract: In this paper,the impact of posite thickness on corona-resistant property was studied. The results showed that the thickness of corona-resistant layer had to be higher than a critical value in order to gain better pulse voltage endurance. For example, the critical thickness of corona-resistant layer is between and . For the three-layered wire, the best coating formula is that pure enamel is used as the primer coat, the posite layer in the center have to be thick enough to provide pulse voltage endurance and the polyamide-imide is used as outlayer.
Key words: corona-resistance; enameled wire; insulation
1前言
第一届世界环境史大会(WCEH 2009)的召开标志着环境保护的理念已从局部地区向全球化发展。变频调速作为节能的重要技术曾被列入国家重点推广的十大高新科技之一[1],但变频调速给绝缘材料的耐电晕性能提出了更高的要求。近10年来,我国在耐电晕绝缘材料的制备技术方面取得了令人满意的成绩。上海汉邦化工有限公司和四川东材企业集团分别将具有电屏蔽功能的组分引入高分子漆基树脂制成耐电晕漆包线漆[2],[3]。株洲时代新材料科技股份
