Electric distribution device, installation comprising such a device, and electrical protection process
First Claim
1. An electrical distribution device comprising an input for connection of an incoming electrical line, electrical protection means connected to the input and comprising electrical distribution feeders designed to supply electrical loads, said protection means comprising:
- a main part comprising main breaking means connected to the input for connecting the incoming electrical line, and main control means for controlling opening and closing of the main breaking means, an electrical power distribution line connected to the main breaking means of the main part, and at least one secondary part separated from the main part and comprising at least one secondary breaking device and secondary control means to command opening and closing of at least one secondary breaking device, said at least one secondary breaking device being connected to said distribution line and to at least one electrical distribution feeder, the secondary control means enabling opening of at least one secondary breaking device if a current flowing in said breaking device is lower than a preset opening current threshold.

Abstract
The electrical distribution device comprises a main part comprising main breaking means, at least one secondary part comprising at least one secondary breaking device, and an electrical power distribution line connected between the main and secondary parts. The secondary part comprises secondary control means enabling opening of at least one secondary breaking device if a current flowing in said breaking device is lower than a preset opening current threshold. A distributed electrical installation comprises at least one such device. An electrical protection process for an electrical distribution device comprises an opening step of the secondary breaking means when a current flowing in these means is lower than a preset opening current threshold following detection of a fault.

22. An electrical protection process for an electrical distribution device comprising:
-
a first step of detection of an electrical fault in secondary breaking means connected by a distribution line and a communication line to main breaking means, a step of beginning of transmission of a priority opening command signal on said communication line to command opening of the main breaking means, a first step of opening of the main breaking means commanded by transmission of said priority opening command signal on said communication line, a second step of opening of the secondary breaking means when a current flowing in these means is lower than a preset opening current threshold value following detection of a fault at the first detection step, a step of end of transmission of the priority opening command signal, a step of closing of the main breaking means after the end of transmission of the priority opening command signal step.
