Abstract

345,681. Pressure-relieving devices for Suids. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and GOODMAN, J., of General Electric Co., Witton, Birmingham. Aug. 18, 1930, No. 36311/29. [Class 135.] Relates to oil-immersed electrical apparatus such as transformers and switches in which the casing 4 is provided with a pressure-relief device comprising an outlet pipe closed by a glass or other rupturable diaphragm 9, and consists in providing a trap or sump for intercepting moisture condensing on the walls of the device above the oil level. The trap may be formed by a truncated conical member 2 closed by a gauze 11 and provided with a flange 10 clamped between the parts 1, 3 of the outlet pipe. A small outlet 6 may be provided in the upper part of the pipe for relieving pressure due to rise of oil level under normal conditions: a breather may be attached on removing the bolt 24. A tap for draining the sump may also be provided.
