<p><P>PROBLEM TO BE SOLVED: To provide a compact gas-insulated switchgear obtained by constructing and connecting a bus-side equipment unit, a circuit breaker unit, and a line-side equipment unit in this order, which makes it possible to easily access a current transformer secondary terminal box without increasing the distance between circuits. <P>SOLUTION: The gas-insulating switchgear includes: the current transformer 1 housed in a horizontal branch portion for connecting the circuit breaker unit and the line-side equipment unit; the secondary lead wire of the current transformer 1 running from the current transformer 1 and going through the area in proximity to a circuit breaker operating/driving portion along the inner wall face of the case of the circuit breaker unit; and the secondary terminal box that is disposed at the lower part on the bus-side equipment unit side in the case of the circuit breaker unit and to which the secondary lead wire of the current transformer 1 is connected. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
