1000kV特高压交流变电站构支架横梁施工新技术及装备研究

Study on Construction Technology and Equipment of Supporting Structure Beams in 1000 kV UHVAC Substation

当前我国1000kV交流特高压试验示范工程南阳开关站的构支架施工已完成。文章对流动式起重机组立、抱杆组立、液压提升组立等3种施工方案进行了比较,并结合1000kV变电站构支架横梁的参数及场地等情况,选用了液压提升组立方案。该施工方案在我国构架横梁施工中为首次使用。对该方案(包括配套设备钢索式液压提升装置)作了介绍,并给出了详细的施工步骤。

Now the construction of supporting structure beam for Nanyang Switch Nation of 1 000 kV UHVAC demonstration project in China has been completed. The paper compared 3 kinds of construction scheme including hydraulic lifting equipment scheme, which was selected for the first time used in the construction of supporting structure beam in China, combined with the parameters of supporting structure beam for 1000 kV substation. This scheme was introduced, and the construction steps was given in detail.
