摘要

±1 100 kV换流变压器作为±1 100 kV直流输电工程中的关键主设备

由于电压等级和容量的大幅提高

换流变压器体积和重量均超出了运输界限

非常有必要采用解体运输并现场组装的方案。文中针对±1 100 kV换流变压器现场组装提出了4种可能的方案:单器身临时油箱运输组装方案;双器身临时油箱运输组装方案;组件运输、现场组装方案;两台换流变压器串并联时运输组装方案。对4种方案的可行性和适用范围进行对比后

认为组件运输、现场组装方案为±1 100 kV换流变压器现场组装的最佳方案。

Abstract

±1 100 kV converter transformer is the key equipment of ± 1 100 k V HVDC project. The volume andweight of the converter transformer exceed the limit of transportation due to the large increase of voltage level and ca-pacity. Accordingly it is necessary to use the disintegrating transportation and on-site assembly. In this paper

4 pos-sible schemes are proposed for the transportation and on-site assembly of the ±1 100 k V converter transformer

in-cluding scheme of using single-body temporary oil tank

scheme of using dual-body temporary oil tank

scheme ofcomponents transportation and on-site assembly and scheme of two converter transformers in series or in parallel. Af-ter comparing the feasibility and applicability of the 4 schemes

it is considered that scheme of components transpor-tation and on-site assembly is the best scheme for the ±1 100 kV converter transformer.
