Power device water cooling pipeline for high-power converter of rolling mill

The invention relates to the technical field of converter equipment, and discloses a power device water cooling pipeline for a high-power converter of a rolling mill, which comprises a bottom plate, the top of the bottom plate is bolted with a water pump through a fixing piece, two ports of the water pump are respectively bolted with a water inlet pipe and a water outlet pipe, and the top of the bottom plate is provided with a water tank. The other end of the water inlet pipe is communicated with the bottom of the water tank; a first valve is mounted on the surface of the water inlet pipe; the second connecting pipe is connected with the converter, then the second connecting pipe is connected with the first connecting pipe through the fixing bolt, the connecting pipes can be detached independently, the maintenance cost is reduced, the practicability is improved, meanwhile, the first valve is rotated to drive the water inlet pipe to conduct current limiting, the second valve is rotated after the water inlet pi
