Overvoltage Protection Resistors TRIZ Cases
- Surge Arrester Enclosure Fracture Path for Controlled Pressure Relief
A predefined enclosure fracture path relieves fault pressure in a surge arrester while stopping uncontrolled ejection of critical parts.
- DC Lightning Arrester Voltage Layout for Diode-Protected Power Supplies
Different arrester operating voltages let DC power supplies safely shunt lightning surges to ground even when diodes block normal varistor action.
- Protection Adapter Surge Impedance for High-Voltage Overvoltage Control
A surge-impedance adapter cuts high-voltage line transients before they reach operating equipment, improving protection farther from grounding points.
- Varistor Protection Module With Fail-Safe Arc Fusing
A meltable bypass path and arc-fusing mechanism prevent varistor overheating, cracking, and fire risk during high-current surges.
- Varistor Housing Module With Fail-Safe Overheating Protection
A conductive housing, arc fusion, and meltable bypass help varistor modules absorb surges while preventing overheating, arcing, and fire.
- Bidirectional Asymmetric TVS Structure for Stable Breakdown Control
A monolithic P+N−P+ TVS with isolation diffusion shifts peak E-field into the bulk to cut breakdown variation, leakage, and surge losses.
- Sealed Surge Arrester Disconnector With End-Fitting Guided Contact
An end-fitting guided contact enables external disconnection in a sealed surge arrester, cutting moving mass and preventing SF6 release.
- Surge Arrestor Module Curing with Variable Bladder Compaction
Variable radial and axial bladder pressure cures epoxy-wrapped MOV stacks with fewer voids and surface defects, reducing post-curing smoothing.
- Gas-Tight Surge Arrester With Optimized Electrode Geometry
A gas-tight surge arrester uses pin-shaped electrodes with a specific spacing ratio to ensure reliable ignition at high response voltages.
- Surge Arrester Collar Absorbing Explosion Energy
Extendable collar absorbs explosion energy, preventing varistor fragment ejection and cage destruction.
- Varistor Degradation Alarm Circuit with Segmented Thermal Protection
Segmenting the thermal fuse into a parallel path allows the varistor to maintain protective functionality and alert users to excessive current passage.
- Surge Protection Device with Lattice Fuse Element
A surge protection device integrates a cylindrical fuse element with a lattice structure to rapidly interrupt short-circuit currents.
- Fiber-Reinforced Plastic Profile Carrier for High-Voltage Insulation
Segmented hollow profiles reduce weight and cost while maintaining electrical insulation for high-voltage applications.
- Off-Center Crimping with Profiled Deformation Tools
Profiled deformation tools vary wall displacement to achieve uniform gripping pressure, preventing glass fiber crushing during off-center crimping.
- TVS Device with SAS Diode for AC Transient Suppression
A transient voltage suppressor uses a silicon avalanche suppressor diode to limit high-voltage transients on AC powerlines.
- Multilayer Varistor Component with Dielectric Vias for Low Capacitance ESD Protection
A multilayer component uses dielectric vias filled with conductive material to form discharge paths while minimizing overall capacitance.
- Varistor Surge Arrester With Thermal Disconnect
A compact varistor assembly integrates a thermal disconnect element to isolate the component from circuitry.
