Abstract
A converter valve includes a top shielding cover, a bottom shielding cover, at least two vertically stacked valve layers, and a maintenance platform. The top shielding cover is disposed at an upper portion of an uppermost valve layer. The bottom shielding cover is disposed at a lower portion of a lowermost valve layer. Each of the valve layers comprises two valve modules disposed side-by-side in a horizontal direction. The two valve modules are electrically connected via a busbar and mechanically connected via securing connectors. A lower valve layer is connected to an upper valve layer in a suspended manner. A body of the maintenance platform is located between horizontal planes on which two vertically adjacent valve layers are located, or between horizontal planes on which the lowermost valve layer and the bottom shielding cover are located.
