<P>PROBLEM TO BE SOLVED: To simplify a structure of a breaker tank and rationalize a layout of an operational mechanism of the breaker in a GIS. <P>SOLUTION: The three-phase integrated GIS 1 having the breaker tank 4 for accommodating a breaker section 8 and the other tank 3 vertically stacked, is provided with a means for connecting main circuits of the circuit breaker tank and the adjacent tank and forming a space 6 between the breaker tank and the adjacent tank, and the operational mechanism 21 disposed in the formed space and coupling between an operational apparatus and a driving section of the breaker. In the breaker tank, a planar section for attaching the operational apparatus 17 on a front face is unnecessary. Since the operational mechanism of the breaker conventionally accommodated in the operational apparatus is partially or wholly disposed in the space between the tanks, the operational apparatus is miniaturized and a space within an operational control box 2 can be effectively utilized. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
