Description

technical field

[0001] The invention relates to a transformer, in particular to an intelligent stepless capacity-adjusting power distribution transformer used in a power system. Background technique

[0002] The loss of the transformer occupies a very considerable proportion in the loss of the power grid, especially the large distribution network. Distribution transformers are widely used and their power loss has attracted much attention. Therefore, the loss reduction of distribution transformers is directly related to the economic benefits of power companies and society.

[0003] Distribution transformers are mainly used in rural power grids and urban distribution networks. Rural power grid load has the characteristics of strong seasonality and large peak-to-valley difference in power consumption. The difference between the peak and valley of the urban power grid is more obvious, and its peak and valley rotation is more frequent. However, in order to meet the power dema...
