Abstract
A device including a phase-change heat-transfer fluid cooling mechanism to cool a sheath in which is placed switchgear such as a circuit breaker. An evaporator is thus created which is connected to condensers that are placed on a roof of the sheath. The device can be for application to a medium-voltage high-current electrical installation. The device requires little maintenance and only consumes a reduced amount of energy, or even no energy.
Claims12
A cooling method for cooling a medium-voltage, high-current installation for handling and transferring electricity, the installation including current-transporting and current-breaking gear placed in at least one sheath, the method comprising:
- cooling walls of the at least one sheath with cooling elements having a phase-change heat-transfer liquid directly situated in contact with the walls of the at least one sheath.
A cooling device for a medium-voltage, high-current installation for handling and transporting electricity, the installation including current-transporting and current-breaking gear placed in at least one sheath, the device comprising:
- a cooling element of the at least one sheath operating with a phase-change heat-transfer liquid to cool directly the at least one sheath directly situated in contact with the at least one sheath.
