Relay Ventilation/Cooling/Heating TRIZ Cases
- Relay Contact Chamber Pressure Relief for Arc-Sealed Safety
A break-open pressure relief valve keeps the relay contact chamber sealed for arc extinction, then vents excess gas to prevent explosion.
- Pressure-Relief Relay Structure for Sealed Contact Chamber Explosion Risk
A break-open pressure relief valve vents excess gas from a sealed relay contact chamber before overload or short-circuit pressure causes explosion.
- Relay Contact Chamber Pressure Relief for Arc-Sealed DC Switching
A break-open pressure relief valve vents overpressure from a sealed relay contact chamber, preventing explosion while preserving arc extinguishing.
- Relay Pressure Relief Valve Assembly for Sealed Contact Chambers
A break-open valve on the relay yoke plate releases excess gas from a sealed contact chamber before fault pressure can cause explosion.
- Relay Bus Bar Layout for Wire Access and Heat Dissipation
An obliquely upward relay connector and inclined bus bar create wire access without raising the relay or weakening heat transfer.
- Contactor Heat Transfer Assembly for Higher Current Capacity
A heat transfer assembly cools fixed contacts through conduction and coolant flow, raising contactor current capacity without overheating.
