Protective Switch Details TRIZ Cases
- Centered Operating Handle for Two-Pole Circuit Breaker
Segmented handle projections coordinate dual pole operation, resolving the contradiction between simplified appearance and effective coordination.
- Pyro-Switch Shunt Resistor Protection Diode
A protection diode dissipates stored energy from a pyro-switch cutting a shunt resistor, preventing high voltage damage to battery systems.
- Ring Main Unit Interlock Device Cam Mechanism
Cam and spring mechanism in ring main unit interlock prevents fuse cover closure when cable cover is open, stopping dielectric breakdown risk.
- Gas Circuit Breaker Exhaust Insulation Cover Design
PTFE insulation covers shield exhaust holes from thermal impact, maintaining reliability in downsized gas circuit breaker units.
- Modular Circuit Breaker Assembly with Orthogonal Guiding and Clamping
A modular circuit breaker uses orthogonal projections and clamping screws to guide and hold blocks during assembly.
- Modular Power Distributor with Resistor Chain Addressing
Serial base resistors create an addressing chain that enables automatic fault detection, reducing assembly labor and wiring costs in modular power distributors.
- Circuit Breaker Energy Transfer System for Contact Bounce
Rotatable member with biasing element absorbs impact forces to reduce contact wear and arcing in miniature circuit breakers.
- Magnetic Trip Mechanism Removable Sub-Assembly
Pre-charged spring sub-assembly eliminates winding during assembly, enabling quick tripping current adjustment.
- Differential Protection Device Torus Space Optimization
A differential protection device integrates a small Rogowski sensor above the measurement torus to enable precise current detection across all phase conductors.
- Secondary Trip System for Circuit Breaker Opening Time
Magnetic trip device actuates contact arm assembly via movable armature and linkage system.
