Switchgear Arrangements TRIZ Cases
- Switchgear Cable Compartment Cover for Arc Overpressure Resistance
A reinforced front cover with variable thickness and secure fastening helps switchgear cable compartments withstand arc overpressure and absorb energy.
- Multifunctional Switchgear Duct With Pressure-Activated Arc Sealing
A pressure-activated sealing flap lets switchgear cooling air in during normal use, then blocks gas escape during arc events to save space and simplify installation.
- Resettable Current Interruption Module for Legacy Electrical Connectors
A vacuum-interrupter module adds resettable fault interruption to legacy electrical connectors, avoiding replacement after activation.
- Insulation Gas Pre-Fill in Power Devices to Slow Pressure Loss
Pre-filling the insulation component with dissolved gas slows chamber pressure decay, extending refill intervals in gas-insulated power devices.
- Subsea Vacuum Circuit Breaker for High-Voltage Pressure Isolation
Pressure-compensated vacuum interrupters enable subsea circuit breaking above 72 kV and 1250A while withstanding water pressures up to 300 bar.
- Tank Circuit Breaker Suspension Using Series Springs for Vibration Relief
Series springs suspend the fixed-side frame to absorb vibration and thermal expansion, preventing joint damage without enlarging the breaker.
- Mobile Grid Power Access for Electric Fracturing Pumps
Utility-grid power, mobile substations, and parallel transformers replace diesel fracturing equipment to cut noise, fuel cost, and maintenance.
- GIS Partial Discharge Synchronization Using AC Reference Switching
An AC reference switch and inverter create one synchronized GIS signal, cutting wiring complexity and improving partial discharge source identification.
- AC Reference Switching for GIS Partial Discharge Synchronization
An AC reference switch and inverter simplify GIS partial discharge synchronization across multiple sensors while reducing wiring complexity and short-circuit risk.
- Vacuum Bottle Housing With Ice Shield for Underarm Switch Safety
An ice-and-water-shielded vacuum bottle housing protects underarm vacuum switches while avoiding SF-6 and preserving a visible open gap.
- Switchgear Vent Flap Locking for Arc Pressure Gas Containment
A spring-biased vent flap closes and locks under arc pressure, containing hot gases while preserving normal switchgear airflow.
- Wireless Gas Pressure Monitoring for High-Voltage Switchgear
Continuous wireless pressure and temperature sensing cuts switchgear wiring and footprint while supporting precise remote gas monitoring.
