Abstract

The invention relates to a valve module of a horizontal thyristor valve block, which comprises a shielding cover assembly, thyristor assemblies, a resistor assembly, electric reactor assemblies, a capacitor assembly, a water pipe assembly and an optical cable groove assembly, wherein the shielding cover assembly comprises shielding covers, insulators and metal beams; the thyristor assembly comprises thyristor units, thyristor trigger units and radiators; and the water pipe assembly is composed of a main water pipe and branch water pipes, and the water pipes are installed on the metal frame through insulating supports. The valve module of the horizontal thyristor valve block adopts a three-dimensional structural design, and has the advantages of simple and tidy wiring and small occupied area through layered arrangement.

Description

technical field [0001] The invention belongs to the technical field of power electronics, and in particular relates to a horizontal thyristor valve group valve module. Background technique [0002] At present, the highest voltage level applied in domestic direct-mounted SVC technology is 66kV, and the more common ones are 35kV and 10kV, and the structures are all vertical structures. Although the quality of the power grid has been greatly improved, it is still unsatisfactory in terms of construction costs and line losses, and the vertical structure has great limitations, that is, the height cannot exceed a certain limit, otherwise the structural stability cannot be guaranteed. . [0003] The above description means that the traditional SVC technology needs to continue to be upgraded and improved. The direct-mounted 110kV TCR thyristor valve group is currently the key technology of direct-mounted SVC with the highest voltage level in China. Its application can greatly impro...
