<p>A single phase transformer comprises an iron core main column (1), a first iron core side column (2) and a second iron core side column (3), wherein a low-voltage coil (11), a medium-voltage coil (13) and a high-voltage coil (14) are sleeved on the iron core main column from the inside to the outside in turn. An excitation coil (21) and a voltage regulation coil (12) are sleeved on the first iron core side column from the inside to the outside in turn. The excitation coil is connected with the medium-voltage coil sleeved on the iron core main column in parallel in order to regulate the voltage of the voltage regulation coil. By sleeving the voltage regulation coil on the first iron core side column, the transformer can conveniently wind the coil, avoid manufacturing risk, improve operation reliability, and effectively reduces the overall width of the transformer.</p> |
