Protective Switch Operating/Release Mechanisms TRIZ Cases
- Remote Control Actuation Mechanism for Circuit Breakers
Telescopic connecting rods with spring means extend the actuator stroke to reduce mechanical stress at end-of-travel positions.
- Overcurrent Protection Device Using Thermo Magnetically-Shiftable Material
Replacing bulky bimetallic strips, the device uses a thermo magnetically-shiftable material to merge thermal and magnetic protection into one compact unit.
- Electric Switching Device Differential Protection Voltage Interruption
An electric switching device interrupts supply voltage to actuation means after contact decoupling.
- Circuit Breaker Locking Device Using Magnetic Actuation
A magnetic actuator oscillates a pressing plate to engage a locking end, preventing accidental reactivation after a fault.
- Circuit Breaker Signalling Device with Pivoting Lever Mechanism
A pivoting body and lever mechanism transmit motion from a circuit breaker to a micro-switch, reducing mechanical stress on the switch.
- Circuit Breaker Assembly Segmentation for Stability
Segmented assemblies maintain positional stability despite quick release switching speeds.
- Proximity Sensor Test Actuation for Electrical Switching Panels
A proximity sensor detects a target through the panel to actuate the test circuit without mechanical contact.
- Switchgear Contact Bridge Damping for Bounce Prevention
A damping element slows the return movement of a switchgear contact bridge to prevent premature closing.
