ABSTRACT:
A bus bar connecting arrangement for a gas insulated switchgear designed to reduce the overall size thereof and the number of component parts, thereby decreasing the required installation space and trimming the production costs. The bus bar connecting arrangement comprises: a pair of first and second bus bars disposed in a spaced apart relation with each other; a first and a second disconnecting switch unit connected in the first and second bus bars, respectively; a circuit interrupter provided with a single opening and including at least one pair of movable and stationary contacts for opening and closing an electrical circuit connecting between the first and second bus bars; a current transformer unit adapted to be interposed between the first and second bus bars and the circuit interrupter and having at least one current transformer; first connecting conductors extending from the first bus bar into the circuit interrupter through the current transformer unit and the opening in the circuit interrupter for electrical connection between the first bus bar and the movable contact of the circuit interrupter; and second connecting conductors extending from the second bus bar into the circuit interrupter through the current transformer unit and the opening in the circuit interrupter for electrical connection between the second bus bar and the stationary contact of the circuit interrupter.
