Abstract

Disclosed is a HVDC valve tower. The HVDC valve tower includes cylindrical valve module loading part, a valve module loaded on the valve module loading part, and a crane disposed at a center of the valve module loading part to be rotatable.

First claim

What is claimed is:

1. A HVDC valve tower comprising:
a cylindrical valve module loading part having a plurality of stacked layers, wherein each layer of the stacked layers comprises a bottom frame and a plurality of sliding parts, each of the sliding parts is coupled to the bottom frame to be slideable in a radial direction;
a valve module loaded on a respective one of the sliding parts of the valve module loading part; and
a crane rotatably disposed at a center of a top layer of the plurality of the stacked layers of the valve module loading part.

2. The HVDC valve tower according to claim 1 , wherein each of the sliding parts comprises, a guide part configured to be fixed to the bottom frame, and a moving part configured to be guided by the guide part to be moved in the radial direction, and the valve module is located on the moving part.

3. The HVDC valve tower according to claim 2 , wherein the moving part comprises a first cut-away part passing through the moving part in an up and down direction.

4. The HVDC valve tower according to claim 3 , wherein the bottom frame has a plurality of second cut-away parts passing through the bottom frame in an up and down direction, each of the second cut-away parts aligned with a respective one of the sliding parts.

5. The HVDC valve tower according to claim 4 , wherein the first cut-away part and the respective one of the second cut-away parts are disposed to be overlapped with each other, when the respective one of the sliding parts is slid to an inside of the bottom frame.

6. The HVDC valve tower according to claim 2 , wherein a protruding part is provided at a lower portion of the valve module, and the moving part has a concave portion which is opened upwardly and dented concavely downwardly, and the protruding part of the valve module is received in the concave portion of the moving part.

7. The HVDC valve tower according to claim 1 , wherein a crane fixing part is provided on an upper portion of the valve module, the crane fixing part is coupled with a crane for lifting the valve module.
