Problems solved by technology

[0003] At present, the structure of the flexible DC transmission valve tower at home and abroad is a floor-standing vertical structure. For example, a support connection structure for a high-voltage DC converter valve disclosed in the Chinese utility model patent with application number 200820149242.7. The inner insulators installed between the bottom valve group and the upper valve group adjacent to it and between the upper valve groups adjacent to each other in turn make each upper valve group connected in series above the bottom valve group, and the inner insulator The support components set at both ends are fixedly connected to the opposite valve groups, so as to achieve the effect of fixed support; at the same time, the main water of the cooling system of the valve tower is introduced from the lower part of the valve tower, and the main water pipes are arranged from bottom to top. Branch water pipes are led from the main water pipe to the valve modules

Example Embodiment

[0023] An embodiment of the method for assembling the flexible DC transmission suspension valve tower of the present invention: the assembling method includes the following steps: the first step is to hang the top-level valve group under the steel beam of the building through the suspension connection structure. The suspension connection structure includes an insulator, a U-bolt buckled at one end of the insulator, and an eight-shaped ring hinged on the other end of the insulator; in the second step, the lower valve groups are connected in turn through the suspension connection structure under the top valve group Suspended below the top valve block.

[0024] The embodiment of the flexible DC transmission suspension valve tower of the present invention: Figure 1 to Figure 4 As shown, the valve tower includes a top-level valve group 1 and a three-level lower-level valve group 2. Both the top-level valve group 1 and the lower-level valve group 2 have four connection angles 3 locate...

Abstract

The invention relates to a flexible direct current transmission suspended type valve tower, an assembly method and a suspension connection structure thereof. According to the invention, a top layer valve group is suspended on a steel beam of a building through the suspension connection structure; the suspension connection structures are connected between the top layer valve group and an adjacent lower valve group and between every two adjacent lower valve groups; the suspension connection structure comprises an insulator, a U-shaped bolt fastened with one end of the insulator, and an 8-shaped ring hinged with the other end of the insulator, so that all the lower layer valve groups can be sequentially suspended below the top layer valve group, the valve tower forms an integral suspended structure, and the overall shock resistance of the valve tower is further improved; and as the valve tower ensures that all layers of the valve groups are suspended below the steel beam of the building through the 8-shaped rings, the external insulators and the U-shaped bolts, the valve tower can be conveniently and rapidly assembled on site, and the work efficiency of valve tower assembly is improved.

Description

technical field [0001] The invention relates to high-power electric power electronic rectification and inverter devices in the technical field of flexible direct current transmission engineering, in particular to an assembly method of a flexible direct current transmission suspension type converter valve tower, and also relates to the flexible direct current transmission suspension type valve Tower and its suspension connection structure. Background technique [0002] Flexible DC transmission is a new generation of DC transmission technology with the voltage source converter as the core. Compared with AC transmission and conventional DC transmission, flexible DC transmission can flexibly adjust the voltage of the AC system while transmitting energy. Therefore, flexible DC Power transmission has obvious advantages such as good controllability, flexible operation mode, and many applicable occasions. Therefore, under the new form of current power grid construction that is incre...
