Circuit-Breaking Switch Details TRIZ Cases
- Circuit Breaker Layout With Lateral Transmission and Larger Arc Chamber
A lateral transmission layout frees vertical space for a larger arc extinguishing chamber while avoiding mechanism interference in compact breakers.
- Circuit Breaker Reset Hook Mechanism for Reliable Drawer Rearming
A reset hook and drawer hook use switching-handle force to rearm the drawer reliably when spring power alone is insufficient.
- Air-Blowing Trip Mechanism With Integrated Reset Arm Sealing
Gas-driven tripping uses an integrated reset arm and sealed cavity to simplify molded case circuit breaker reset and improve reliability.
- Air Circuit Breaker Arc Extinction with Segmented Gas Discharge
Segmented grids and filters guide breaker arcs along predefined paths while improving gas discharge and preventing unwanted arc spreading.
- Limiter Air Circuit Breaker with Blow Open Arrangement
Electrodynamic force actuates a carrier assembly latch pin to rapidly break contact, limiting fault energy and preventing arc flash damage.
- Movable Contactor Assembly for Current Limiting Circuit Breakers
A movable contactor assembly uses curved protrusions and integrated springs to maintain electrical contact.
