Switches With Movable Electrical Contacts TRIZ Cases
- Vacuum Interrupter Pole Structure for Heat Dissipation and Switch Integration
A U-shaped thermoplastic shell and conductive connector improve vacuum interrupter pole cooling, weight, and three-position switch integration.
- Fuse Grounding Contact for Floating Circuit Protection
An elastic contact inside the fuse casing grounds floating circuit sections during replacement, avoiding extra switches and electrical hazards.
- Electrode Input Mechanism With Braking to Prevent Contact Damage
A braking mass decelerates the moving electrode near contact to limit impact, reduce welding, and preserve insulation reliability.
- Knife Switch Arc Guidance Using Integrated Cooling Gas Outlets
Cooling gas outlets around the fixed arcing contact steer and cool the arc, improving interruption reliability with fewer moving parts.
- Air Break Switch Blade Lock Against Premature Pivoting
A detent-backed blade lock prevents momentum or bounce from causing premature pivoting, keeping air break switch closure stable.
- Arc Extinguishing Unit With Magnetic Arc Path and Magnet Protection
A sealed magnet case guides arcs toward the grid by magnetic field, enabling fast arc extinguishment in air circuit breakers without guide plates.
- Medium-Voltage Switchgear Contact Design Using Dry Air and Vacuum Interruption
Pressurized dry air and a vacuum interrupter improve medium-voltage switching insulation and arc quenching without SF6.
- Arc Horn Spring Catch for Stable High-Voltage Switch Interruption
A spring catch holds the actuating arm against the moving arc horn during switch opening, preventing bounce, arc damage, and premature wear.
- Vacuum Interrupter Switch Timing to Prevent Closing Arcs
A rod-and-blade sequence closes the vacuum interrupter before blade contact, preventing high-voltage switch arcing without upstream shutdown.
- Air Break Switch Blade Lock for Stable Jaw Seating
A two-axis blade lock prevents premature rolling until the blade seats in the jaw, improving high-voltage switch connection stability.
- Knife Switch De-Latching Mechanism for Puffer Arc Extinction
A de-latching puffer lets the contact lever reach earth position while preserving peak gas pressure for arc extinction during interruption.
- Medium-Voltage Switching Pole With Bistable Vacuum Interrupter Drive
A bistable linkage synchronizes rotary and linear contacts in a vacuum interrupter to improve arc quenching, insulation, and SF6-free switching.
- Medium-Voltage Switching Pole With Vacuum Interrupter Linkage
A bistable transmission links gas-side contacts to a vacuum interrupter, improving medium-voltage arc quenching, insulation, and compactness.
- Vacuum-Interrupter Switch Sequencing to Prevent High-Voltage Arcing
A blade-and-rod switch uses staged disengagement with a vacuum interrupter to suppress high-voltage arcing without cutting power upstream.
- Disconnect Switch Linkage Alignment for Faster Closed-Position Calibration
A line-of-sight straight edge simplifies three-phase disconnect switch calibration by reducing trial-and-error in the fully closed position.
- Wear-Contact Switch Structure to Prevent Arc Damage
Intermediate wear contacts take the arc during switching, protecting the arm and terminal from material loss and extending switch life.
- Medium-Voltage Switching Pole with Bistable Vacuum Interrupter
A bistable vacuum interrupter links rotary and linear contacts to maintain arc quenching and insulation in compact medium-voltage switching poles.
- Magnet-Cased Arc Extinguishing Unit for Compact Arc Control
A sealed magnet case forms a compact magnetic field that drives arcs outward for faster extinction while protecting the magnet from arc damage.
- Integrated Switchgear Module With Interlocked Isolator and Grounding
Combining isolator, circuit breaker, and ground electrode functions in one interlocked module saves switchgear space and cuts support parts.
- Blade Position Detector for High Voltage Disconnect Switch
Optical sensors detect switch blade seating to prevent incomplete contact in high voltage disconnect switches.
