摘要:
面对我国能源分布不均、发电能源与用电负荷分布不平衡的现状,远距离、大规模输电成为有效解决这一问题的主要方案,其中特高压直流输电更是因其具备输电容量大、输送距离远、节约输电走廊的特点而成为首选,由我国自主设计研发投入使用的世界上第一条±800 kV楚穗直流输电工程,自投运以来一直未开展相关抽检研究工作,且无国内外相关运行经验可以参考借鉴,其较高的输电地位决定了其安全稳定运行的重要性,本文对取自楚穗直流输电线路的共计48片玻璃绝缘子开展了电气性能测试、材料性能测试、机械强度测试、金属附件测试等一系列机电特性测试试验,对楚穗直流输电线路挂网运行的玻璃绝缘子的运行性能进行分析,同时为后续特高压直流输电线路绝缘子运行维护及选型提供借鉴。
Abstract:
In view of the uneven energy distribution and unbalanced distribution of power generation and electricity load in China, long-distance and large-scale power transmission has become the main solution to effectively solve this problem, among which UHV DC transmission is the best choice due to its large transmission capacity. Chusui transmission project, the first ±800 kV DC transmission project in the world, has not carried out random sampling and research work since its operation, and has no relevant operating experience as a reference. A series of mechanical and electrical characteristic tests on a total of 48 glass insulators from Chusui DC transmission lines have been performed, such as electrical performance test, material performance test, mechanical strength test and metal attachment test. This paper analyzes the operating performance of the glass insulators in Chushui DC transmission line, and provides reference for the operation and maintenance of the UHVDC transmission line insulators and their selection.
