The bottom package outlet board of described plenum chamber cylinder barrel, inserting place with piston rod in the outlet board is provided with sealing ring.
Part between inherent dividing plate of described thermal expansion chamber cylinder barrel and the spout forms the thermal expansion chamber, and the part between inherent dividing plate of plenum chamber cylinder barrel and the outlet board forms plenum chamber.
The outer cover that described piston rod inserts the part in the cylinder barrel of thermal expansion chamber is equipped with baffle, and the termination of baffle is provided with little spout.
The technical scheme of the cylinder of of the present utility model pair of chamber self-energized thermal expansion type SF 6 arc-extinguishing chamber of circuit breaker is: this cylinder comprises the thermal expansion chamber and the plenum chamber of piston rod, cylinder barrel and interior mutual isolation thereof, and the cylinder barrel of described cylinder is to be made of the thermal expansion chamber cylinder barrel that the plenum chamber cylinder barrel of bottom lock and slip are plugged in the plenum chamber cylinder barrel; Cylinder barrel bottom, described thermal expansion chamber envelope is provided with dividing plate, dividing plate is provided with the non-return valve that can open and close according to the thermal expansion stream pressure size that electric arc produces, described piston rod upper end is plugged in the cylinder barrel of thermal expansion chamber and by dividing plate and thermal expansion chamber cylinder barrel and is connected, piston-rod lower end passes from plenum chamber cylinder barrel bottom, the inherent dividing plate of thermal expansion chamber cylinder barrel top forms the thermal expansion chamber, and the inherent dividing plate of plenum chamber cylinder barrel below forms plenum chamber.
Self energy type sulfur hexafluoride breaker cylinder of the present utility model, originally the thermal expansion chamber and the plenum chamber that were one are separated, become two parts, the thermal expansion chamber is a moving component, and the parts that constitute plenum chamber do not move, when divide-shut brake, piston rod only need drive the thermal expansion cylinder barrel motion at place, thermal expansion chamber and can finish the work, compare with existing pair of chamber self-energized thermal expansion type SF 6 arc-extinguishing chamber of circuit breaker, the utility model has reduced the volume and the quality (weight) of moving component, has reduced operating work simultaneously, makes mechanism realize miniaturization, improved the utilance of material, the easier processing of part.
