ABSTRACT:
The system ensures electric feed for which purpose it has an alternating current motor (1) coupled to an alternator (2) which is coupled to a hydraulic motor (8) which in turn is coupled to a diesel engine (7.)
The alternating current motor is coupled by means of a clutch (6) to a high pressure pump (5.)
All the elements are governed by a control circuit (4) so that in the absence of network, it simultaneously drives the diesel engine (7) and the hydraulic motor (8) the latter initially maintaining the angular speed of the alternator, until the diesel engine (7) attains its normal working conditions; as of when it is mechanically coupled to the alternator (2), the hydraulic motor (8) remaining turned off.
The high pressure pump is capable of being directly coupled to the diesel engine (7) with which the hydraulic motor (8) is the one which maintains the angular speed of the alternator (2) at all times.
