摘要
Oil cooling system, particularly for transformers feeding traction electric motors and for oil in a high viscosity condition, which system comprises a first heat exchanger from a heat generating source to the cooling oil, which is connected by at least a delivery duct and at least a return duct to a second heat exchanger for cooling the oil, by transmitting the heat absorbed into the first heat exchanger to an environment having a temperature lower than the one of the cooling oil, moreover there being provided means for flowing the cooling oil from the first to the second heat exchanger and vice versa and means for monitoring the oil flow into the circuit composed of said first and said second heat exchangers and of said delivery and return ducts which means for monitoring the flow control means for indicating operating conditions of the cooling system and/or means for performing safety operations against the heat generating source being overheated.
