The invention provides a converter valve tower with saturable reactors being centralized arranged. A plurality of groups of longitudinal reactor modules are suspended outside valve modules, and an alternating current sequentially enters the valve modules through one group of reactor modules, and is converted into a direct current in the valve modules, and then the direct current flows out of the remaining reactor modules. According to the invention, the reactor modules are independently suspended, and are disposed outside the valve modules, thereby effectively eliminating the impact on an internal electrical device of the valve tower from the vibration of the saturable reactors, preventing the vibration from causing the loosening of a connector of cooling pipes in the valve modules and thewater seepage and leakage.
