Abstract
The utility model relates to a transformer, in particular to a dry-type transformer for single-phase 10kV and 20kV mutual conversion. The transformer comprises an iron core, wherein a winding is wound on the iron core. The transformer is characterized in that the winding is divided into a low-voltage winding and a high-voltage winding, wherein switching between serial connection and parallel connection of the low-voltage winding and the high-voltage winding is realized through a connecting plate; the iron core is of a rectangular structure and is formed by coiling an amorphous alloy belt; the low-voltage winding is formed by winding a foil; and the high-voltage winding is made from a vacuum casting resin. Therefore, the transformer has the beneficial effects of high overload ability, high short circuit resistance, low no-load loss and resource saving.
