本发明属于直流输电换流阀领域，特别涉及一种行车悬吊阀塔结构。
背景技术
直流换流阀是高压直流输电的关键部件，体积庞大、自重大、运行电压高。目前单个商用电力电子器件耐压最高达到8.5kV，需要几十甚至近百级器件串联才能达到换流阀的运行电压要求，这些器件一般分多层在空间中分布构成换流阀。鉴于换流阀的结构、耐压要求，直流换流阀通常采用悬吊结构，运行中的直流换流阀通常悬吊于换流阀大厅顶部的主梁上，固定安装。
直流换流阀组成复杂，在出厂时必须对换流阀及各组成部分进行相应的试验，试验过程中换流阀也须采用悬吊结构，通常有两种方式。方式一为参照实际运行方式将换流阀悬吊于试验大厅房顶的主梁上，对试验大厅要求较高，特别是已建成的试验大厅不一定能满足要求，且这种方式换流阀为固定安装，需长期占用试验场地，无法进行其他试验。另一种方式为采用龙门架悬吊，在试验大厅内组建一组龙门架，将换流阀悬吊于龙门架上，这种方式需在试验大厅内修建一组龙门架，同样占用了试验大厅，影响其他试验。在CN101128389B中公开了一种吊运器及吊具组件，该吊运器可以实现对重物的悬吊，但该发明的主要目的在于对重物的运输，其结构及部件均不适合长时间悬吊。
