Abstract

350,779. Switchgear structures. FELTEN & GUILLEAUME, CARLSWERK AKT.-GES., M³lheim, Cologne, Germany. July 18, 1930, No. 21763. Convention date, Aug. 28, 1929. [Class 38 (v).] In metal-clad switchgear structures with oil switches and multiple bus-bar selector devices which may be of the interchangeable plug type as described in Specification 231,947, [Class 38 (v), Electric switches &c.], or of the change-over selector switch type as described in Specification 245,529, [Class 38 (v), Electric switches &c.], an auxiliary change-over switch is automatically controlled by the selector switch (or by the usual indicator switch in conjunction with the movable plugs) for switching over the voltage circuits of the measuring instruments and devices on to the respective voltage transformer of the bus-bar in use at the moment.
