Abstract
The invention is applied to the technical field of transformers, and provides a transformer for a power system. The transformer for the power system is provided with a core on which a low-voltage winding and a high-voltage winding are wound respectively. The high-voltage winding is wound outside the low-voltage winding. An insulating layer is arranged between the low-voltage winding and the high-voltage winding. The low-voltage winding is formed by winding a plurality of sections of copper foils. An insulating layer is also arranged between every two adjacent layers of copper belts. The transformer for the power system also comprises a temperature control device, and the temperature control device comprises a temperature sensor buried in the low-voltage winding. The transformer for the power system comprises the core, and the low-voltage winding and the high-voltage winding, which are wound on the core, the high-voltage winding is wound outside the low-voltage winding which is formed by winding an integral section of copper foil, and an insulating layer is arranged between every two layers of the copper foil, so that the anti-short-circuit capability of the transformer is enhanced, the transformer has balanced ampere-turns, a good radiation effect and low loss, and the running reliability of the transformer is improved.
