<p>Provided is a ground setting type transformer device. On a side wall (6b1) of a transformer box (6), a sheath installation part (201b2) arranged on a switch box (201) of a LBS is connected across a sealing ring (16); primary sheath terminals (14u) to (14w) installed on the sheath installation part are lead into the transformer box (6) by a sheath leading window part (6h0) arranged on a side wall (6b1). A heat insulation plate (21) for covering part of the periphery of a window part (6h) is configured on the inner side of the transformer box (6) to restrain the rising of the temperature of the sealing ring (16). Parts of oil through parts of the primary sheath terminals (14u) to (14w) close to the LBS are used as a separating object (14B1); a sheath terminal isolation part (25) is arranged for isolating the separating object from the convection current of insulating oil (7) generated in the transformer box so as to restrain the heating of the insulating oil for the primary sheath terminals and to restrain the rising of temperatures of the sealing ring (16).</p> |
