Claims

[Scope of utility model registration request]

A transformer with a single-phase three-legged core structure in which the winding is wound only on the central core leg, the core is sandwiched between upper and lower core clamping brackets, and a cover plate is passed between these upper and lower clamping brackets. In this case, no cover plate is inserted into the central core leg around which the winding is wound, but the strength is provided by the upper and lower core tightening fittings and the cover plates of the outer core legs. Features a transformer coil and core tightening device.
