Example Embodiment

[0033] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following describes the present invention in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0034] Such as figure 1 , figure 2 The 800kV converter station AC filter combined structure shown mainly includes the main frame column 1, the slave frame column 7, the slave end frame column 8 and the main frame column 9. The main frame column 9 is "1" The said slave frame column 7 is preferably a herringbone column; the main end frame column 1, the slave end frame column 8, the main frame column 9, and the slave frame column 7 together form a matrix structure, and the main end frame column 1 The frame column 8 from the end is located at the same end of the matrix structure, and a number ...

Abstract

The invention provides a slave end framework column for an 800kV convertor station alternating current filter united framework. The slave end framework column is a three-legged framework and comprises a first supporting column (81) and two second supporting columns (84). A framework shaped like a Chinese character 'ren' is formed by the two second supporting columns (84). An end connecting plate (86) is formed at one end of the first supporting column (81). A main coupling part (88) is formed at one end of each second supporting column (84). The head of a connecting pin (87) penetrates the end connecting plate (86) and the main coupling parts (88) and connect the first supporting column (81) and the second supporting columns (84) into the three-legged framework. After being mounted in place, the slave end framework column has good stability and structural stiffness, and therefore the overall lateral stiffness of the 800kV convertor station alternating current filter united framework can be improved, and the overall wind load and earthquake resistance of the 800kV convertor station alternating current filter united framework is enhanced.

Description

technical field [0001] The invention relates to the structural design of the combined frame of the AC filter of the 800kV converter station, in particular to a secondary frame column used for the combined frame of the AC filter of the 800kV converter station. Background technique [0002] In the field of UHV DC transmission in electric power engineering, such as ±800kV converter station, it is necessary to implement the current 800kV power transmission according to the electrical layout in the station, and the wires in the station pass through the outgoing line frame, incoming line frame, and AC filter frame. [0003] However, both sides of the AC filter frame of the existing converter station need to be provided with frame end braces, resulting in a complex overall structure of the frame and a large amount of steel, which is not conducive to cost saving. In addition, the existing AC filter frame of the converter station mainly adopts the herringbone column scheme, which not...
