Reduced compression self extinction method for high voltage circuit breakers

摘要

The reduced compression self extinction method has a first tube (6) with a second outer tube (7). The outer tube has a forward section with contact breakers (14) and an air flow chamber (16). There is a compression chamber (9) with a piston (11) and inner spring section (23). The piston has a blocking mechanism preventing its movement beyond a certain point. The piston moves axially along a rail.
