ABSTRACT:
A power-distribution network for the energization of a multiplicity of loads comprises a two-conductor trunk extending from a DC supply, a plurality of parallel primary branches connected to the trunk via respective first overload-responsive circuit breakers, and a plurality of parallel secondary branches connected to each primary branch via respective second overload-responsive circuit breakers. Each secondary branch terminates at one or more DC/AC converters feeding associated loads, the converter frequencies being suppressed in the supply network by filters included in the second circuit breakers. Each circuit breaker further includes at least one capacitor which, in the event of a short circuit in a parallel branch, supplies the associated loads for a time long enough to let the supply voltage substantially recover its normal value.
