Abstract

The invention discloses a hanging valve tower for a converter valve. The hanging valve tower comprises more than two valve layers arranged up and down at intervals, wherein an interlayer connection structure is connected between every two adjacent valve layers and comprises interlayer threaded sleeves respectively fixed in corresponding positions of each valve layer and arranged at intervals in the circumferential direction; the interlayer threaded sleeves of every two adjacent valve layers mutually correspond in an up-and-down pairwise manner; an interlayer stud is connected between every two interlayer threaded sleeves corresponding up and down; and all the interlayer studs are made from epoxy resin glass fibers. The interlayer studs made of epoxy resin glass fibers has not only high strength and rigidity but also favorable electric insulation performance, can bear very large bending stress, ensures that the valve tower has a certain of flexibility on the basis of relative rigidity, reduces relative sway of the valve layers, and enhances the shock resistance of the valve tower.

Description

technical field [0001] The invention relates to a high-power power electronic rectification and inverter device, in particular to a suspension valve tower adopting a rigid-flexible connection structure. Background technique [0002] In the power system, the suspended valve tower of the converter valve is formed by successively connecting several valve layers arranged at intervals up and down. For example, the Chinese patent application number 201110067680.5 discloses a thyristor converter valve for high-voltage direct current transmission. Each valve layer of the valve tower represents an independent electrical unit, and the electrical unit modules on it include a valve module and a reactor module; the top valve layer and the bottom valve layer are respectively connected with top Shielding cover and bottom shielding cover, the periphery of each valve layer is also equipped with an intermediate shielding cover; in addition, in order to cool the valve module, a water cooling s...
