<p>PURPOSE:To improve reliability while miniaturizing the transformer by logically arranging the connections of gas insulating buses among each vessel and reducing the number of lead drawing sections and connecting buses. CONSTITUTION:The vessels 1, 2 each represent each phase vessel of the transformer and a LVR vessel, and a connecting bus vessel 3 is arranged in parallel in the direction of arangement of the vessels 1, 2. Three conductors 5a, 5b, 5c are incorporated into the vessel 3, and insulated by a noninflammable insulating gas. The vessel 3 has a branch bus 4 for connection, and is connected to the vessels 1, 2. The winding terminals a1, a2, b1, b2, c1, c2 of the connecting lead sections of the vessels 1 are set up in parallel with a central axis of the vessel 3, and each connected to the conecting buses 5a, 5b, 5b, 5c, 5c, 5a. The excitation winding terminals a, b, c of the connecting lead sections of the vessel 2 are connected to the conductors 5a, 5b, 5c. Accordingly, the positions of connection can be reduced, and reliability is improved.</p> |
