Abstract
1,208,360. No break supply systems. SIEMENS A.G. 27 Sept., 1968 [30 Sept., 1967], No. 46166/68. Heading H2H. An installation comprises a source of alternating current RST, rectifier 3, a D.C. to A.C. converter 5 having its input side connected to the output side of rectifier 3 to receive power from it, the two forming a static frequency converter 2, a rotary dynamo electric machine 8 which is coupled to a flywheel 10 and is connected to the output side 3a of rectifier 3, and a motor 7, the arrangement being such that when a load 1 is connected to the output side of the frequency converter 2, the input side of the rectifier 3 is being fed with alternating current from source RST and machine 8 is running, a brief reduction in the voltage on the input side of rectifier 3 results in the machine 8 acting as a generator, temporarily supplying the D.C. to A.C. converter 5. As shown 4 is a smoothing arrangement, and machine 8 is a synchronous rotary generator coupled to an asynchronous motor 7 and generator 8 is connected to output side 3a through a rectifier 9. Both rectifiers 3 and 9 may be controllable. The frequency of the output current of frequency converter 2 may be adjustable. Rectifier 9 may be a bridge rectifier constructed with thyristors. In a second arrangement, Fig. 2 (not shown) rectifier 9 is eliminated and machine 8a is a D.C. generator coupled to a synchronous or asynchronous motor. When the generator has been run up to speed, the motor may be de-energized and the generator may operate as a motor supplied from rectifier 3 until it is caused to operate as a generator due to a drop in voltage at the busbars RST.
