Problems solved by technology

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.

Abstract

The invention relates to a horizontal directly-linked thyristor valve block. The horizontal directly-linked thyristor valve block is formed by overlapping three layers of single-layer valve blocks. Each single-layer valve block comprises a shielding case, supporting structural parts, cross beams and silicon stacks, wherein the shielding case, the supporting structural parts and the cross beams form a frame; the silicon stacks are transversely, horizontally and fixedly placed on the cross beams; interlaminar water pipes, water resistors and capacitors are further mounted on the cross beams. The single-layer valve blocks are fixedly connected together through interlaminar insulators. The lowermost single-layer valve block is fixed to the ground through the bottom insulators and bases. The horizontal directly-linked thyristor valve block is convenient to install, simple in structure, light in weight, good in stability and small in occupied area.

Description

technical field [0001] The invention relates to a horizontal straight hanging thyristor valve group. Background technique [0002] At present, the highest voltage level applied in the 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 the key technology of direct-mounted SVC with the highest voltage level at present. Its application can greatly improve the accuracy of reactive power compensation in the power supply system, and e...
