Abstract

157,943. Siemens - Schuckertwerke. Dec. 8, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Systems depending on the use of static transformers; systems depending on the use of two or more machines.- Additional transiormers or generators are automatically switched in, in accordance with the load, by means of a thermal or pneumatic switch. An oil or sand bath a, Fig. 1, contains a heating coil b, connected in parallel with a line resistance d, and a thermometer e provided with contacts h and i in the circuits of relays f and g respectively, which control the switching of additional transformers or generators. The thermometer may be placed in the oil bath of the transformer. In the modification shown in Fig. 2, a motor k connected in parallel with a line resistance d drives a pump m to vary the pressure in a vessel n. A pressure gauge p controls an alarm circuit or the switching of the additional unit.
