<p>PURPOSE:To provide a small and light-weight transformer with a small space for installation by a method wherein a substance of a core-type transformer and a substance of a shunt reactor are piled to the height direction with one of yokes of the transformer core as a common magnetic path and a primary winding of the transformer and a reactor winding are connected in parallel with the same polarity and housed in a common tank. CONSTITUTION:Reactor windings 7a-7c are wound around main legs 4a-4c of a gapped core and the gapped core is held between an upper yoke 4d and an upper yoke 2d of a transformer core so that a transformer and a shunt reactor are composed into one body. The corresponding legs 2a and 4a, 2b and 4b, 2c and 4c of the transformer core and the reactor core are so formed as to have their central positions of the magnetic paths coincide with each other. The reactor core 4 is housed in a tank 1 in such a manner that it is piled on the transformer core 2. The reactor windings 7a-7c are star-connected like the primary windings 3A-3C of the transformer and connected to the same power system U, V, W in parallel.</p> |
