Transformers TRIZ Cases
- Variable Transformer Ratio for Short-Circuit Current Discrimination
A variable transformer modifies output current to trigger downstream protection devices.
- High-Voltage Transformer Shielding Layer Grounding
Grounded shielding layers eliminate external voltage hazards in epoxy resin transformers, enabling compact designs with higher power density.
- Wireless Power Antenna Alignment via Received Power Feedback
Corrects microwave transmission deviations by dynamically orienting antennas based on detected power, reducing leakage without complex positioning hardware.
- Coil Device Manufacturing Seed Layer Etching Heat Reduction
Bonding copper foil to a base layer, etching the pattern, and plating a conductive layer reduces heat generation while improving charging efficiency.
- Multifunctional Current Sensor with Dual Windings for Switchgear
A multifunctional current sensor integrates inner and external windings within a single housing to detect electrical quantities simultaneously.
- Wireless Power Coil Unit Reducing Induced Voltage on Metal Parts
Split reactance circuits balance winding potentials to reduce high induced voltage on metal parts caused by parasitic capacitance in wireless power systems.
- Transformer Probe Fault Isolation via Segmented Primary Coils
Segmented primary coils with low impedance coupling isolate open circuit faults in one channel, preserving signal integrity across other channels.
- Fault Current Limiter With Liquid Dielectric Immersion
Immersing AC coils in a liquid dielectric medium overcomes air insulation limits, enabling high voltage fault current limiting.
