System for producing and distributing electrical energy for vehicles particularly aircraft, as well as an electrical power center for such a system
First Claim
1. In a system for producing and distributing electrical energy for aircraft having at least two motors, said system comprising at least two main generators of D.C. or A.C. type moved by the motors of the aircraft, at least one storage battery, starters for said motors, an electrical power centre formed by primary bars supplied from said main generators, primary contactors and primary circuit breakers, an assembly of secondary bars supplied from the primary bars, secondary contactors and secondary circuit breakers, an assembly of relay boxes and electrical bays, an assembly of electronic bays, control panels, user devices, as well as a plurality of regulating and/or protecting means for the generators, the battery and the starters, the improvement comprising a central unit grouping together said electrical power centre, a part of said assembly of circuit breakers and secondary contactors, and said regulating and/or protecting means, the rest of said assembly 10 of circuit breakers and secondary contactors being distributed bewteen the assembly of relay boxes and electrical bays, the assembly 12 of electronic bays and each of the control panels,said central unit comprising:
- as many primary bars of normal supply as there are generators, each of said primary bars of normal supply being supplied by one generator through means for protecting the latter and supplying at least one secondary bar of normal supply through a first primary circuit breaker;
a primary bar of essential and emergency supply connected to said battery through means for protecting and regulating the latter and to each of said primary bars of normal supply by a plurality of primary contactors and supplying a plurality of secondary bars of essential and emergency supply through the second primary circuit breakers; and
at least one secondary circuit breaker and one secondary contactor directly connecting a secondary bar to the battery.

Abstract
In a system including an electrical power center for producing and distributing electrical energy for vehicles, particularly aircraft, primary circuit breakers and contactors are distributed between a D.C. electrical power center, relay boxes, electronic bays and control panels and the electrical power center forms a central unit grouping together different protection or safety devices. The system permits the electrical network on board an aircraft to be simplified and lightened.
