Circuit-Breaking Switch Contacts TRIZ Cases
- Floating Contact Assembly for Circuit Breaker Arcing
A floating contact assembly rotates to self-align with moving contacts during engagement.
- Composite Movable Contact Arm for Circuit Breaker
Copper core and fiberglass reinforcement minimize weight while maintaining conductivity, reducing let-through current during short-circuit interruption.
- Circuit Breaker Moving Contact Assembly Positional Error Correction
Curved guiding faces and angled sliding surfaces return the moving contact to its normal position, correcting positional errors that cause contact failures.
- High Voltage Switch with Rotary Actuator and Planar Substrate
A high-voltage switch uses a rotary actuator to rotate a non-conductive arm on a planar substrate for circuit reconfiguration.
- Floating Antifriction Disc Rim Wall for Circuit Breaker Drive Pin Protection
Partial rim walls on the antifriction disc deflect arc gases and contaminants away from drive pin interfaces to prevent cross-phase short circuits.
- Rotatable Static Contact for Circuit Breaker Arc Blow-Out
Integrated limiting step surfaces prevent axial deviation while rotation accelerates arc blow-out.
- Multi-Finger Electrical Contact Assemblies with Unequal Resistance
A multi-finger electrical contact assembly uses unequal resistance paths to balance current distribution across fingers.
- Copper-Steel Static Contact Support for Circuit Breakers
A copper base layer and steel reinforcing layer form a static contact support that conducts current with minimal heat generation.
- Movable Contact Spring Mechanism for Circuit Breaker Assembly
Cylindrical housings with straight grooves guide shafts while spiral springs provide bearing zones, simplifying articulation sub-assembly maintenance.
