Abstract

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.

Description

technical field [0001] The invention relates to the technical field of valve towers, in particular to a current valve tower with centralized arrangement of saturated reactors. Background technique [0002] The converter valve is the core equipment of the DC transmission project. By sequentially connecting the three-phase AC voltage to the DC terminal, the desired DC voltage is obtained and power control is realized. [0003] At present, the converter valves integrate the reactor inside the valve module. The disadvantage of this structure is that the high-frequency vibration of the reactor affects the key components, boards and connectors of the module, resulting in the loosening of the components inside the converter valve. , At the same time, the water pipe joint will become loose due to the vibration of the reactor, causing water seepage and water leakage. Unreliable electrical connection and water leakage will affect the normal operation of the valve tower, and serious c...
