ABSTRACT:
A fluid-cooled thyristor valve including a plurality of series-connected thyristors that are cooled by non-conducting fluid flowing through electrically conducting cooling bodies positioned at the anode and cathode sides of the thyristors. The cooling bodies at opposite sides of adjacent thyristors are connected by fluid pipes that pass the cooling fluid. A plurality of electrically conducting sections of pipe connect the cooling body on the anode side and the cooling body on the cathode side of adjacent thyristors to pass the cooling fluid in one direction and to electrically connect the thyristors in series through the electrically conducting cooling bodies. A plurality of electrically insulated sections of pipe connects the cooling body on the cathode side and the cooling body on the anode side of adjacent thyristors to pass the cooling fluid in the opposite direction. A cooling body of each thyristor is attached in an insulated relation to a support beam and each thyristor and its associated unattached cooling body is detachably clamped to the associated attached cooling body. The electrically conducting pipe may be positioned to cross the insulated pipe between adjacent thyristors to uniformly place the thyristors.
