Preferably, described stiff end is fixed by welding on the described single-phase transformer.
Preferably, the stiff end of described linking arm is fixed on the side of described single-phase transformer, and described linking arm is perpendicular to the side of described single-phase transformer.
Preferably, the described syndeton that removably connects is that bolt connects, sells any one in connection, the key connection.
Preferably, the described syndeton that removably connects is that bolt connects, and described link has the through hole that passes for bolt.
Preferably, connection metal bellows between described single-phase transformer is provided with in the described metal bellows for the interconnective electrical wiring of described single-phase transformer.
Preferably, described three single-phase transformers are arranged along a straight line, and described linking arm is fixedly connected with the adjacent side of adjacent single-phase transformer.
In the three-phase combined transformer of the present utility model, to utilize linking arm that three single-phase transformers are joined together to form an integral body, simultaneously can guarantee three accuracys that single-phase transformer is in place, save base, reduced the overall weight of product, reduce the execute-in-place difficulty.
