High tension isolating switch with a mobile contact movable at high speed

摘要

The electrical circuit breaker has a moving contact section (2) and fixed contact port (1) and a rear rod (3), moving the mo contact. The rod moves the inner piston (5) in stages with a first (7) and second spring (6). The rod and spring system are lock (8) in a first position until the moving contact is connected to the fixed contact. The second spring is then released, pushing moving contact at speed into the fixed contact.
