Buchanan Ingersoll & Rooney PC
Gas insulated switchgear
Each integral unit is structured by arranging partial units (I), (II), and (Ill) side by side, while line-side devices are branched from positions between the partial units adjacent to each other. Each of the partial units is structured by connecting a current transformer and a disconnector in sequence to each of upper and lower outlets horizontally drawn out from a lateral face of a vertical-type circuit breaker in the same direction. Any two partial units positioned adjacent to each other are connected in series by connecting the disconnectors included therein with a connection bus. The line-side devices are positioned to oppose the circuit breakers while the disconnectors are interposed therebetween. The switchgear includes a plurality of integral units. Two ends of each of the integral units are respectively connected to two main buses that are provided in an upper position and a lower position while the disconnectors are interposed therebetween.
