Abstract

The present invention relates to a thyristor converter valve assembly. The thyristor converter valve assembly comprises a carrier on which a left valve unit and a right valve unit are arranged. Each valve unit includes reactor assemblies, resistor radiators and thyristor radiators. The thyristor converter valve assembly further comprises a water cooling system for cooling the reactor assemblies, the resistor radiators and the thyristor radiators. The water cooling system includes a main water in-coming path and a main water returning path which are communicated by a first water branch, a second water branch and a third water branch arranged in parallel. The reactor assemblies and the thyristor radiators of the left valve unit are all connected in series in the first water branch. The reactor assemblies and the thyristor radiators of the right valve unit are all connected in series in the second water branch. The resistor radiators of the left valve unit and the right valve unit are all connected in series in the third water branch. The thyristor converter valve assembly provided by the invention has a water cooling system and is simple in structure.
