  • Oil cooling system, particularly for transformers feeding traction electric motors, transformer with said system and method for determining the cooling fluid flow in a cooling system
    Patent number: 7812699
    Abstract: An oil cooling system, which may be employed for transformers feeding traction electric motors and for oil in a high viscosity condition, includes a first heat exchanger between a heat generating source to cooling oil that is connected by delivery and return ducts to a second heat exchanger cooling the oil by transmitting the heat absorbed at the first heat exchanger to an environment having a lower temperature than the cooling oil. The oil cooling system also includes devices flowing the cooling oil from the first to the second heat exchanger and vice versa, and devices monitoring oil flow in the circuit, for example by indicating operating conditions of the cooling system and/or by performing safety operations when the heat generating source becomes overheated.
