TRANSFORMER HAVING AN INTERLOCKING CORE FRAME

摘要

A distribution transformer having an interlocking core frame is provided. The core frame encloses a transformer core having at least one phase and provides compression on the core of the transformer to bind the assembly together. First and second clamps of the core frame contain receiving cut-out portions for the tabbed leg plates. The core clamp cut-out portions and leg plate tabs form an interlocking connection. A first section of the first and second clamps, contacting the leg plates at an angle perpendicular to the leg plates provides support to retain the interlocked position between the first and second clamps and corresponding leg plates. Lifting eyebolts are provided in the first core clamps for moving and mounting the transformer at the desired location.
