Improvements to the assemblies in order to generate an alternating electrical energy is constant and without cut-off frequency

摘要

The invention relates to supplying electrical power at constant frequency (F) and without break in an electrical load (Z), with the aid of a unit comprising an alternator (7), an electric motor (4) for driving this alternator, normally powered by the mains (5), a shutter (3), a back-up heat engine (1), and a clutch (2). A differential gear (11) is interposed between the shafts A of the electric motor and B of the alternator, and the cage (14) of this gear is driven from the shaft A, with the aid of a hydraulic assembly (18, 21, 24) regulated by a feed regulator (25), at a speed such that the speed of the shaft B remains constantly equal to a set point value.
