ABSTRACT:
A cylindrical housing for a high voltage circuit breaker is filled with sulfur hexafluoride and receives three parallel elongated puffer interrupters arranged with their axes on the apices of an equilateral triangle. A single triangular support plate receives one end of each interrupter and supports them in cantilever. The triangular plate is fixed to the housing by thin steel straps affixed to respective apices of the plate. Filter bags in a removable tray are disposed along the horizontal bottom of the housing. Bushings enter the tank through openings in the tank wall. The openings receive slotted flexible tubes which wrap around the slot edges to serve as corona rings. The bushings each have an integral central conductive stud and conductive end plate.
