摘要
特高压直流换流站阀厅设计中,换流阀与换流变及穿墙套管之间连接时需使用特殊的管母连接金具。结合溪洛渡-金华换流站工程中阀厅金具的设计经验,对阀厅金具的设计提出了相应的技术要求,分析了金具的载流量及温升、防电晕特性及无线电干扰水平、机械强度、外形以及连接形式等要求,通过典型实例介绍了换流变套管接口处的金具、直流穿墙套管接口处的金具以及管母线连接金具。
In the design of UHVDC convertor station valve hall, the connections among the convertor valve,convertor transformers and DC Wall Bushing have to use special connection fittings.In this paper, combined with design experience of convertor station valve hall in Xiluodu-jinhua,and proposed technical requirements to design of valve hall fittings, and analysed the requirements of fittings＇ current carrying capacity and temperature-rise,anti-corona characteristics and radio interference level,mechanical strength,shapes and the connection types. At last, this paper introduced the fittings of convertor transformer bushing,DC Wall Bushing fittings and pipe fittings through representative instance.
