Title:
LOSS HEAT UTILIZING DEVICE FOR INDUCTION ELECTRIC APPARATUS
Document Type and Number:
Japanese Patent JPS5752115
Kind Code:
A
Abstract:
Method and device of utilizing, through heat exchanger or heat pump provided in addition to a normal cooling system, heat due to energy loss in a coil device, such as a transformer or a choke coil having a liquid-cooled interior, which includes throttling the normal cooling system so as to set a difference between the temperature of the interior liquid coolant, at a location under a casing cover of the coil device, and a maximum permissible temperature for a normal useful life of insulation for the coil winding so that the temperature of the inner coolant is lower when the coil device is under full load than when it is under partial load.
