A monitoring-and-control drawer () for an electrical connection enclosure comprises a front part () comprising a ventilation grille (), a back portion () at which a back ventilation region is provided and functional elements (). The heat generated by the functional elements is removed by an air flow (FL) which enters the functional unit via each air grating in the front part and re-emerges from the functional unit via the back ventilation region, having passed right through the functional unit. The back portion belongs to a base of the drawer to which the functional elements are attached and comprises a group of upstream connectors () connected to an electricity source, a group of downstream connectors () connected to an electrical load and a ventilation orifice () which is part of to the back ventilation region and which is located between the group of upstream connectors and the group of downstream connectors.

Functional unit for electrical connection enclosure, and electrical connection enclosure comprising such a functional unit

An electrical connection enclosure () is supplied with electrical power by power supply cables () and supply at least one electrical load (). The enclosure comprises a power supply column () and at least one connection column (). Each connection column comprises at least one monitoring-and-control unit () connected to an electrical load, electrically protected by a protection unit () and configured to allow the connection and potentially the driving and/or the surveillance of an electrical load. The electrical enclosure is controlled by an industrial computer (). Each connection column comprises a communication module () which centralizes operating information originating from the monitoring-and-control units of that connection column, transmits this operating information to the industrial computer, receives commands originating from the industrial computer and transmits these commands to the monitoring-and-control units of that connection column. At least one communication module comprises a power supply board delivering at least one auxiliary voltage to each connection column

Electrical connection enclosure

The electric conversion stage according to the invention can be connected on one hand to intermediate terminals of a DC voltage electric bus, and on the other hand to output terminals. It comprises P switching branches, P&#x2267;2, the switching branches being connected in parallel between the intermediate terminals, each switching branch including first and second controllable electronic switches connected serially and connected to each other by a midpoint, each switch including a semiconductor switching element and a diode connected in anti-parallel to the semiconductor element, and means for controlling the electronic switches according to a control law. It also comprises a capacitor connected between the two output terminals and, for each switching branch, an electromagnetic coil connected between a terminal of the capacitor and the midpoint of the corresponding switching branch, and the control law is selected from among a first control law and a second control law, the first control law being such that the semiconductor element of each first switch is always off, and the second control law being such that the semiconductor element of each second switch is always off.
