Problems solved by technology

[0002] For a small-capacity transformer with a transformer capacity of about 315KVA, the voltage on the high and low voltage sides is relatively low, such as a transformer with a voltage of about 420V on the high voltage side and an output voltage of about 220V on the low voltage side. High, manual operation is difficult to guarantee the quality of the coil; high and low voltage coils need to be operated on specially made hard barrel supports to ensure the overall strength of the coil. After the transformer is manufactured, the overall size is too large, and the required installation big space

Abstract

The invention discloses a small-capacity transformer, which comprises a coil and an iron core, wherein the coil comprises a low-voltage coil and a high-voltage coil; the high-voltage coil is sleeved and wound outside the low-voltage coil; and the coil and the iron core have a rectangular shape. The invention has the advantages that: the transformer is provided with a rectangular coil and a rectangular iron core matched with the rectangular coil; the coil has a high / low-voltage sleeved and wound structure; compared with a transformer with a circular coil, the small-capacity transformer has small volume; the overall dimension of the transformer is reduced; the mounting requirement of a small space can be met; a small-capacity transformer is applicable; and hard barrel supporting pieces in the process of winding the coil are reduced.

Description

technical field [0001] The invention relates to a transformer, especially a small-capacity transformer. Background technique [0002] For a small-capacity transformer with a transformer capacity of about 315KVA, the voltage on the high and low voltage sides is relatively low, such as a transformer with a voltage of about 420V on the high voltage side and an output voltage of about 220V on the low voltage side. High, manual operation is difficult to guarantee the quality of the coil; high and low voltage coils need to be operated on specially made hard barrel supports to ensure the overall strength of the coil. After the transformer is manufactured, the overall size is too large, and the required installation big space. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the purpose of the invention is to provide a transformer with small size and reasonable structure. [0004] Technical solution: A small-capacity transformer include...
