Embodiment Construction

[0014] Embodiments of thyristor valve towers, such as figure 1 As shown, the thyristor converter valve tower includes valve layers. In this embodiment, there are four valve layers stacked from top to bottom, and each valve layer includes two converter valve assemblies 11 arranged side by side at intervals. Two converter valve assemblies on the same valve layer are spaced apart and form a maintenance area between them. The width of the maintenance area is enough for a maintenance person to stand. The maintenance areas on the four valve layers correspond up and down and form a maintenance area together. In the maintenance passage, the upper and lower corresponding converter valve assemblies are fixedly connected together by interlayer hoisting insulators 12. There are aluminum bars 13 at the ends respectively. The aluminum bars 13 are located outside the corresponding converter valve assemblies in the maintenance channel and connect the converter valve components of the same val...

Abstract

The present invention relates to a high-power electrical electronic rectification and inversion apparatus, and specifically relates to a valve tower for thyristor converter valves, applicable in the fields of high-power high-voltage power transmission engineering and high-power direct-current ice melting. The valve tower comprises two or more valve layers which are laminated from top to bottom. Each valve layer includes at least two converter valve assemblies arranged side by side, and adjacent two converter valve assemblies in the same valve layer are arranged with an interval therebetween and fixedly connected together. A maintenance area is formed in the interval between adjacent two converter valve assemblies in the same valve layer, and a maintenance channel for maintenance personnel to get in and out is formed by the maintenance areas in different valve layers in up-down correspondence. According to the invention, the valve tower has the maintenance channel which provides a space for the operation of the maintenance personnel, such that the operation of the maintenance personnel is convenient, and the problem of the inconvenience in the maintenance caused by the small maintenance space of the conventional valve tower for the converter valves is solved.

Description

technical field [0001] The invention relates to a high-power power electronic rectification and inverter device, in particular to a thyristor converter valve tower that can be applied in the field of high-power high-voltage power transmission engineering and the field of high-power DC ice melting. Background technique [0002] As one of the core components in the field of high-power high-voltage power transmission projects and high-power DC ice melting, thyristor converter valve towers have been used more and more widely. A common thyristor converter valve tower is formed by sequentially connecting several thyristor converter valve assemblies (hereinafter referred to as valve assemblies). The layout of the traditional converter valve tower is that several valve assemblies are stacked sequentially from top to bottom, and each valve assembly forms a valve layer. In order to ensure the space distance and creepage distance, the distance between two adjacent valve assemblies Mos...
