Abstract
PURPOSE:To prevent the lowering of the efficiency of heat exchange due to the mixing of a noncondensible insulating gas by mounting a piping returning a refrigeratnt to a transformer tank and a piping recovering the noncondensible gas to a heat exchanger for the refrigerant. CONSTITUTION:The transformer tank 2, the inside thereof encases a transformer proper 1, is filled with the liquid refrigerant 3, the vapor refrigerant 4 and the noncondensible insulating gas 5. The heat exchanger 7 for the refrigerants is connected to the upper section of the transformer tank 2 through a piping 6, and the pipings 8, 11 are mounted to the exchanger 7. When the temperature of the transformer proper 1 rises when operating, the liquid refrigerant 3 is heated and evaporated, and a vapor refrigerant gas 4 enters the exchanger 7 together with the noncondensible gas 5. The refrigerant 3 liquefied in the exchanger 7 is returned to the tank 2 through the piping 11, and the noncondensible gas 5 stored in the upper section of the exchanger 7 is recovered into a tank 10 through the piping 8. When the temperature of the transformer proper 1 drops and pressure in the tank 2 drops, a valve 12 is opened, and the noncondensible gas in the tank 10 is sent in.
