Abstract

PURPOSE:To heighten the stoppage ratio of the cooling tower with respect to the load factor of the transformer by means of a third heat converter provided at the inlet of the circuit on the side of the intermediate refrigerant of the heat exchanger attached to the oil-filled reactor. CONSTITUTION:Heat exchangers 1a-1c and 2a to 2b are attached to the oil-filled transformer 1 and the oil-filling reactor 2 combined for heat exchange between oil and an intermediate refrigerant such as water and fron. The intermediate refrigerant is delivered together to the cooling tower 3 through a common pipe 4 to cooled. A third heat exchanger 5 is attached at the inlet of the common pipe 4 to the oil-filled reactor 2 only to cool the intermediate refrigerant fed to the heat exchanger 5.
