特高压换流站直流场管形母线选择

常规超高压交流变电站设计中，各级电压配电装置母线选择是设计的重要内容之一，而国内工程设计中常忽视直流场母线选择。主要从工作电流、电磁环境、机械强度等几方面重点论述，提出特高压换流站直流场母线型式、截面、对地高度方面要求，同时满足经济性和安全性的要求。

Tubular Busbar Selection in DC Field of UHVDC Converter Station

The selection of busbar type is one of the most important parts in EHVAC substation design.But the busbar selection in DC field is usually ignored in HVDC project design.The working current,electromagnetic environment and mechanical strength of tubular busbar are analyzed.Based on these analyses,an optimal scheme which is about busbar type,conductor section and the height of busbar in UHVDC project is proposed,which has met the requirements of economy and security simultaneously.
