摘要
阀厅金具作为直流输电工程换流站阀厅设备电气连接及固定用装置,连接和组合换流站阀厅电力系统中各类装置,以传递机械、电气负荷及实现某种防护作用。其表面电晕直接影响着阀厅及其设备的表面电场分布,对其表面电场进行仿真具有重要意义。本文基于Infolytica Elec Net电场仿真软件对阀厅金具电场仿真影响因素空气包大小、电极长短进行了研究。结果表明:随着空气包的增大,其表面电场逐渐减少,直至趋于一稳定值;金具表面电场与电极长度无关,其影响可忽略不计。根据研究成果给出了±1100k V直流阀厅金具管母外接头电场仿真结果,对±1100k V特高压直流输电工程阀厅金具的研制具有重要指导作用。
The valve hall fittings as HVDC converter stations valve hall equipment electrical connections and fixing devices, connections and combinations converter station valve hall all types of power system devices to transfer mechanical, electrical load and achieve some kind of protection. It is important to study distribution simulation of its surface electric field on account of a direct impact on its surface corona valve hall and its equipment surface electric field. Based on Infolytica Elec Net electric field simulation software, we investigated air packet size, electrode length. The results show that： with the increase of the air bag, the surface electric field decreases, until tends to a constant value; it has nothing to do with the length of the electrode. According to the research results,we provide electric field simulation results of ±1100k V DC valve hall fittings busbar coupler, the results have an important role in guiding to develop ±1100k V UHV DC transmission project valve hall fittings.
