The invention relates to a connector switch bay for medium voltage switchgear, comprising a first and a second supply device (2, 6), connected together by means of conductors (10, 11, 12, 13, 14, 17, 18, 19, 20, 22, 23) and with a busbar branch (16) on the connector (23), wherein disconnecting means (13, 20) for disconnecting the conducting connection and for disconnecting the busbar branch (16) and earthing means (15, 21) are provided. According to the invention, the above may be improved with a compact construction and simplified operation, wherein the connector switch bay (1) is a gas-insulated switch bay (1) and each of the first and second supply means (2, 6) are connected by a three-way switch (13, 20) to the busbar branch (16) with contact, disconnected and earthed positions.

L'invention concerne un panneau de distribution pour installations de distribution électriques moyenne tension, comprenant un premier et un second dispositifs d'alimentation (2, 6) qui sont connectés entre eux via des moyens conducteurs (10, 11, 12, 13, 14, 17, 18, 19, 20, 22, 23), et une dérivation de barre omnibus (16) avec les moyens conducteurs (23), cependant qu'il est prévu des moyens déconnecteurs (13, 20) pour déconnecter lesdits moyens conducteurs et déconnecter la dérivation de barre omnibus (16), ainsi que des moyens de mise à la terre (15, 21). En vue de perfectionner le panneau de distribution précité en lui conférant une construction compacte et un fonctionnement simplifié, l'invention est caractérisée en ce que le panneau de distribution (1) est réalisé sous la forme d'un panneau de distribution à isolation gazeuse, et en ce que les premiers et seconds dispositifs d'alimentation (2, 6) sont connectés entre eux, via un commutateur à trois positions (13, 20) à savoir en position de contact, de déconnexion et de mise à la terre, avec la dérivation de barre omnibus (16).
