A Double Busbar Electricity Substation, And Interrupting And Selecting Switchgear Designed To Be Used In Said Substation

Abstract: The invention relates to a double busbar electricity substation having two busbar sets(23,24),each of which is received between a central row(40) of metal columns (25)and a parallel side row(41,42)of metal columns (26,27). Each pair of adjacement metal columns (25)of the central row(40)supports a horizontal metal girder(7)that is substantially parallel to said rows, and that itself supports att one pair of insulators, each of which is assigned to a respective phase of the substation, each insulator(13,14)carrying, at one end, a fixed contact(8B,98)that is electrically connected via a cable(10,11)to a busbar(3,4) conveying said phase. The substation incorporates, per phase, one item of interrupting and selecting switchgear comprising a circuit-breaker and two disconnectors(8,9), it being possible for the switchgear to be displaced between an out-of-service position in which it is out of circuit, and an in-service position in which it is connected to the voltage and is held stationary between two central columns(25).
