PURPOSE:To enable to arrange high-voltage lead wires even on the tap changer side at an on-load tap changing transformer by a method wherein a metal shielding plate is arranged under a tap selector, a partioning plate manufactured of an insulator is arranged on the side to face to a winding, and the high-voltage lead wires are arranged under the shielding plate. CONSTITUTION:A transformer main body 5 and an on-load tap changer 2 are accommodated in a transformer case 1. A hight-voltage bushing pocket 13 is protruded on the short-side side of the case 1, a high-pressure gas oil bushing 10 is fitted thereto, and a high-voltage side gas-insulated switchgear 3 is connected thereto. A shielding plate 6 manufactured of a metal is projected horizontally toward the transformer winding side under the tap selector 2b of the changer 2, and an insulatingly partioning plate 7 is provided as to be positioned between the tap selector 2b and the transformer main body 5 from the tip on the winding side of the shielding plate 6. High-voltage lead wires 9 connect the transformer main body and the bushing 10 passing in space between the undersurface of the shileding plate 6 and the bottom of the case 1. |
