CASING LIMITING THE SPREADING AND THE EFFECTS OF SHORT CIRCUITS FOR ELECTRICAL APPARATUSES |
摘要 |
1. A casing for electrical control and/or protection apparatus, the casing being pluggable onto a set of electrical distribution bars and comprising an envelope (10) which defines an enclosure housing the electrical apparatus (12) and parts (13) for connecting said apparatus to the set of distribution bars, characterized in that the enclosure is separated into two volumes (11a, 11b) by a mechanically resistant wall (15), the first volume (11a) forming a compartment containing the electrical apparatus (12) and the second volume (11b) forming a chamber containing the parts (13) for connecting the apparatus to the set of bars, the resistant wall being traversed by the connetion parts and forming a means for returning the over-pressure waves occurring in the chamber following a short circuit, whereas the chamber is limited by a wall element (28) adapted to open in case of an overpressure developed in the chamber. |
