ABSTRACT:
A compressed gas interrupter comprises two contact assemblies each including at least one wear contact and one of which is mobile along an axis relative to the other, which is fixed. The mobile contact assembly is moved along the axis by an insulative maneuvering rod and has a gas compression chamber which, in the open position, communicates via an insulative nozzle with an expansion chamber. The compression chamber includes a piston attached to the hollow wear contact of the mobile contact assembly and which slides in a cylinder attached to the maneuvering rod, the cylinder delimiting the compression chamber with the piston and the nozzle. The hollow wear contact is mobile relative to the maneuvering rod. A system using balls immobilizes the hollow wear contact during initial travel of the maneuvering rod to open the interrupter and constrains the hollow wear contact to move with the maneuvering rod at the end of its travel.
