Switchgear With Horizontal Withdrawal TRIZ Cases
- Switchgear Evaporative Cooling for Primary Contact Hot Spots
Passive evaporators at switchgear primary contacts move heat to a higher condenser, raising current capacity without fan cooling complexity.
- Telescoping Rail Assembly for Drawout Circuit Breaker Alignment
A telescoping carrier and loading rail supports heavy drawout circuit breakers, preventing deflection and simplifying alignment during removal and installation.
- Switchgear Breaker Position Indicator With Single Kinematic Chain
A single kinematic chain synchronizes electrical signals and visual breaker position indication in switchgear, cutting synchronization complexity and cost.
- Primary Stab Bus Insulation Structure for Reduced Partial Discharge
Raised embosses and encapsulated inserts reshape the triple-point gap around a primary stab bus to cut partial discharge and extend insulator life.
- Low voltage switchgear or medium voltage switchgear or high voltage switchgear
A conductive plastic dowel molded into the insulator body provides grounded screw fixing while reducing field concentration and partial discharge.
- Draw-Out Power Tap-Off Assembly for Safe Live Maintenance
Isolated load-side compartments and a draw-out breaker enable safe maintenance access without shutting down upstream power.
- Circuit Breaker Stab Bus Insulation for Reduced Triple-Point Discharge
Raised embosses and curved disk contours increase local gap spacing around a primary stab bus to suppress triple points and partial discharge.
- Withdrawable Feeder Module Switchgear With Sensor-Based Fault Monitoring
Integrated sensors and a withdrawable feeder module enable remote switchgear monitoring, faster fault location, and lower maintenance downtime.
- Integral Auto-Racking for Low-Voltage Breaker Position Control
A motorized racking mechanism with feedback enables remote breaker movement, accurate position monitoring, and reduced arc flash exposure.
- Displaceable Spacer for Low-Voltage Circuit Breaker Clamping
A displaceable spacer member spreads clamping fingers to ease terminal insertion in withdrawable low-voltage circuit breakers.
- Secondary Disconnect Assembly Terminal Retention and Alignment
Cradle assembly retention members engage terminal block protrusions to secure movable inner cradle positioning within electrical switching apparatus.
- Substation Robot with Automated Tool Changing and Safety Interlocks
A substation robot uses automated tool changing to perform maintenance tasks inside energized equipment rooms.
