Abstract

1,072,808. Cooling systems for electrical apparatus. SOC. GENERALS DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM). Sept. 2, 1964 [Sept. 2, 1963], No. 36036/64. Heading F4U. [Also in Divisions Fl, F2 and H2] In an installation which includes a dynamoelectric machine, e.g. alternator 1 having a carcase 3, e.g. a bulb submerged in water, e.g. a river, and containing oil, the carcase interior is so connected by two passages to an oil reservoir 7 above the water level and open to atmospheric air that during operation the oil circulates to continuously extract any water which has penetrated the machine. The passages comprise two pipes 8, 9 of which the former is heat insulated and which respectively enter the upper and lower parts of the carcase to circulate the oil by thermo-siphon effect. The circulation is interrupted when the machine is cold, and may be assisted by a pump. Air circulation in the reservoir may be accelerated by a chimney or a ventilator, and to evacuate a large quantity of water replaceable filter paper, silicagel or molecular screens may be immersed in the reservoir. The alternator is driven by a turbine 6, has a stuffing box 5 and auxiliary circuits 2, and its output and auxiliary cables through the pipe 8.
