<p>PURPOSE:To reduce the installation area of power receiving facility and to improve the reliability of gas seal by fixing a switchgear and a current transformer connected with the primary side of a power receiving transformer to the back of the front wall of the power receiving transformer contained in a box filled with insulating gas. CONSTITUTION:At the front section of an air-tight box 9 (As shown in the side cross-sectional view of a gas insulated power receiving transformer board 14), a partition 9a is provided to the ceiling board 9d across the overall width of the box 9, and a power receiving transformer 2 is contained at the rear section. A case 9b which is projecting when viewed from the sideface is fixed air-tightly from the front face to the front wall of the power receiving transformer 2, and a switchgear, i.e., a vacuum circuitbreaker, comprising an upper primary-side terminal 3a, an intermediate switching section 3b, a lower secondary-side terminal 3c and an operational mechanism 3d is fixed to the rear face of the case 9b. One end of a cooler fixed to the upper face of the ceiling board 9d is coupled with an exhaust port 13A and the other end of the cooler 12 is coupled with a suction port 13B arranged at the front section of the ceiling board 9d.</p> |
