Combined electric appliance main voltage transformer interval phase order conversion device

The utility model relates to the technical field of combined electric appliance main voltage transformer intervals and specifically a combined electric appliance main voltage transformer interval phase order conversion device. The phase order conversion device comprises a shell body and three phase conductors, end parts of the three phase conductors are arranged symmetrically, and an A phase conductor is the longest conductor of the three phase conductors; a conductor supporting device is also included and is arranged on a part, at a minimum vertical distance from the A phase conductor which is the longest conductor, of the shell body; the A phase conductor consists of two segments, and the two segments are connected through the conductor supporting device and are supported on the shell body. The phase order conversion device is characterized by simple and reasonable structure and capability of being used under a condition where two neighboring intervals are at a small distance from each other.
