Air-Break Switch Details TRIZ Cases
- NH Fuse-Disconnector Locking Mechanism for Controlled Fuse Holder Removal
Integrated guiding and locking means stop accidental fuse holder removal in NH fuse-disconnectors while allowing controlled disassembly.
- NH Fuse Disconnector Locking Assembly Without Power Shutdown
A cover passage aligned with the base coupling zone lets an NH fuse disconnector be padlocked without disassembly, shutdown, or loss of IP3X protection.
- Fuse Load Break Switch Cover Structure for Shock-Safe Partial Opening
Interlocking projections and recesses limit partial opening in a fuse load break switch, blocking access to live parts while keeping operation easy.
- Upper Contact Assembly Structure for Low-Loss Fuse Cutouts
A spring-loaded conductive path in the fuse cutout upper contact assembly boosts high-power transmission and cuts power loss.
- Composite Fuse Layout for Compact EMI-Shielded Connection Boxes
A concentric composite fuse and bus bar layout packs fuses densely and uses the negative bus bar as an EMI shield to shrink vehicle connection boxes.
- Fuse Switch Guide Rail Mechanism for One-Motion Parking
A guide rail and linked grooves let the lever open and park the fuse cassette in one motion, improving locking and preventing accidental re-closure.
- Switchgear Interlocking Mechanism for Safe Ground Position Locking
A lock unit, link, shutter, and locking ring block unsafe socket access and breaker movement, reducing electrocution and arcing risks during maintenance.
- Air Circuit Breaker Key Interlock for Draw-In and Draw-Out Control
A unified key interlock lever and shutter plate controls breaker input and draw-in or draw-out movement while simplifying maintenance.
- Switch Blade Position Sensing for Reliable Closed Contact Alignment
Sensors track switch blade position and send signals to a remote device to confirm full closure, avoiding high resistance and overheating.
- Busbar Switching Module Layout for Compact Metering and Easy Exchange
A detachable busbar electronics module places sensing near the conductor to save space while keeping processing parts easy to replace.
- Fuse Cutout Insulator Structure for Longer Creepage Distance
Radial sheds on an extended fuse cutout insulator lengthen creepage and leakage paths, improving high-voltage performance in severe weather.
- Fuse Cover Switching Strip With Retractable Handle for Shallow Cabinets
A pivotable handle and linked fuse covers cut switching strip installation depth while preserving multi-pole switching in shallow control cabinets.
- HH Drop-Out Fuse Mechanism for Sparkless High-Voltage Tripping
A spring-loaded striker lets an HH fuse trip and pivot out without spark flights, reducing fire risk in high-voltage drop-out protection.
- Fuse End Cap Alignment Pin for Rotational Adapter Positioning
A spring-biased displaceable pin in the fuse end cap guides adapter orientation and secure engagement, preventing rotational misalignment.
- Air Circuit Breaker Safety Shutter for Fast Terminal Insulation
A cam-guided shutter exposes or covers breaker terminals during withdrawal and insertion to speed insulation and reduce arc risk.
- Rigidly Linked NH Fuse Switch Covers for Safer Disconnection
Rigidly linking NH fuse switch covers lets one actuation move all covers together, simplifying disconnection and reducing accidental misalignment.
- HV HRC Fuse Swing-Out Mechanism for Spark-Free Drop-Out Protection
A pivoted HV HRC fuse replaces explosive drop-out action to keep visible disconnection while preventing flying sparks and fire risk.
- Switch Blade Position Sensing to Prevent Incomplete Closure Overheating
A blade-position sensor verifies full switch closure, preventing high-resistance contact overheating and improving high-voltage switch reliability.
- Remote Switch Position Sensing for Closed High-Voltage Contacts
Sensors track switch blade position and send remote signals to confirm full closure, preventing contact overheating in high-voltage switches.
- Switching Apparatus Actuator Packaging via Segmented Substrates
Segmented substrates house the actuator to resolve rough glass etching issues, ensuring accurate contact formation.
- Fuse Switch Disc Guide Element for Safe Testing
A resilient guide element directs an operating tool to move a fuse switch disc, preventing contact with live components during testing.
