Abstract
1290648 Gas blast switches; compressed air switches MERLIN GERIN 19 April 1971 [4 March 1970] 22902/71 Heading H1N The apparatus for supplying compressed air to an air blast circuit interrupter, &c., described in Specification 1,239,688, is modified to employ a pressure in the low-pressure container 16 substantially higher than atmospheric pressure. The inlet 35 to the compressor 20 is coupled to a valve 36 arranged so that the compressor draws air from the low-pressure container 16 when the pressure is normal but from the outside through a pipe 40 and filter 41 if the pressure in container 16 is abnormally low. The valve 36 is controlled by a pressure switch 47, sensing the pressure in container 16, and a pilot valve 44. In a second embodiment (Fig. 2, not shown) the valve 36, the compressor 20 and the highpressure container 28 are all arranged outside the low-pressure container 60, an enclosure open to the atmosphere covering the whole apparatus.
