特高压环境OPGW雷击试验标准研究

The Study of Lightning Test Standard of OPGW in Ultra High Voltage Grid

光纤复合架空地线(OPGW)是构建电力系统通信的主要线路,目前常规OPGW已经在电力系统中大规模运用,在500 kV及以下电压等级线路中,其对电网保护有积极作用。在特高压环境下,常规OPGW能否适应特高压环境并正常运行,国内外的研究尚属空白,尤其是相关的标准和针对特高压环境的试验研究都还欠缺。对特高压输电线路OPGW耐雷击性能进行试验研究,确定了特高压输电线路OPGW耐雷击性能的试验方法与判定标准。

Optical Fiber Composite Overhead Ground Wires （OPGW） is main wire that eonstitues power system telecommunication, regular OPGW has been widely applied to electric power system, which has positive influence to protection of power network under 500 kV and below voltage degrade. But under ultra-high voltage environment, whether regular OPGW can be adaptable to ultra-high voltage environment and operate normally or not, which still belongs to blank in the research at home and abroad, no one researches systematically, especially there are still short of related standards and test researches that meets ultra-high voltage environment. The article carries out test research of OPGW anti lightening strike performance through ultra-high voltage transmission line to determine the test method and judge standard of it.
