Abstract

1440377 Switch housings SIEMENS AG 30 Aug 1973 [31 Aug 1972] 40968/73 Heading H1N A flameproof housing has an earthed partition 30 which divides it into high and low voltage chambers and a further earthed partition 25 between the primary and secondary parts of current transformers 23, 24. The primary windings of the transformers are connected between vacuum switch terminals 2], 22 and bushings 16 in the side wall 14 of the housing. The low voltage chamber houses instruments 31.
