Switchgear Arrangements TRIZ Cases
- Triple-Wall Vented Exhaust for Electrical Cabinets
Segmented inner, louver, and outer plates release short-circuit pressure safely while lowering manufacturing costs compared to complex single-component vents.
- Arc Fault Path With Pressure Relief Flaps
Segmented pressure relief flaps redirect expanding plasma away from users while maintaining cooling airflow through air intake louvers.
- Arc Flash Resistant Enclosure Segregated Cooling Paths
Segregated cooling paths in arc flash resistant enclosures direct air from compartments through defined routes to remove heat.
- Self-contained Linkage Module for Dead Tank Circuit Breaker Service
A self-contained linkage module removes as a single unit with the operating mechanism to simplify maintenance of dead tank circuit breakers.
- Sliding Contact Rail for Medium Voltage Switching Unit
A sliding contact rail moves between a busbar and a grounded housing via a U-shaped guide part.
- Sealed Enclosure for GIS Rupture Disc Gas Leak Containment
A sealed polyethylene enclosure captures SF6 leaks at rupture discs, preventing atmospheric release and enabling safe recovery without dismantling flanges.
- Arc Fault Detection via Optical Absorption Spectroscopy
Detecting Fraunhofer lines in incident light enables rapid arc fault identification, avoiding delays from conventional slow overcurrent monitoring.
- Heat Dissipation Support Unit for Switchgear Thermal Management
A heat dissipation support unit transfers thermal energy from high voltage regions to earth potential via a composite core structure.
- Corrugated Hose Gas-Tight Seal in Switchgear Housing
A corrugated hose inserted into a housing bore with an O-ring creates a gas-tight seal without specialized flanging tools.
- Gas-Insulated Vacuum Load Break Switch Design
An inert gas enclosure enables compact vacuum interrupter design, resolving the contradiction between environmental friendliness and device size.
- Semi-Conductive Coating for Closed Insulating Devices
A semi-conductive coating material with composite fillers controls electric fields on equipment surfaces.
- Service Control Panel Rotary Switch Locking Mechanism
Segmented locking mechanisms with intermediary flanges prevent unauthorized access to machine systems while maintaining operational reliability.
- Partial Discharge Sensor VHF Sensitivity
Insulated connecting bolts in a slot antenna adjust resonance frequency, enabling high sensitivity detection of electromagnetic noise in the VHF band.
- UHF Sensor Holding System for High-Voltage Substation Portholes
Segmented fixing elements and inversion locking enable tool-free installation while nesting the sensor against weather damage.
