ABSTRACT:
A heavy duty rectifier having rows of rectifier valves disposed on a rectifier bar which is forced circulation cooled is disclosed. A connecting bar is provided for each row of rectifier valves through which current is supplied to the valves. The rectifier valves are mounted on a broadside of the rectifier bar and the connecting bars are mutually spaced from each other and from the broadside of the rectifier bar. Terminals are provided on mutually facing surfaces of the connecting bars which are arranged at right angles to the broadside of the rectifier bar. The exterior surfaces of the rectifier bar define a first shape having a first area and the exterior surfaces of the connecting bars define a second shape having a second area with the first and second shapes and the first and second areas being substantially matched. Preferably the shapes are rectangular. This arrangement reduces the current deviation along the rectifier and connecting bars.
