Dry-type transformer coil winding method, dry-type transformer coil and dry-type transformer

Abstract

The invention provides a dry-type transformer coil winding method, a dry-type transformer coil and a dry-type transformer, and relates to the technical field of dry-type transformers. The dry-type transformer coil winding method comprises a low-voltage winding method which comprises the following steps of: welding a low-voltage winding tail copper bar x, and winding a copper foil and an insulating layer at the same time according to a preset number of turns, welding a low-voltage winding head copper bar a, and enabling the low-voltage winding tail copper bar x and the low-voltage winding head copper bar a to be located on the same side; and enabling a high-voltage winding head A and a high-voltage winding tail X to be located on the same side. The dry-type transformer coil is manufactured by a dry-type transformer coil winding method. The dry-type transformer comprises the dry-type transformer coil. The technical problem that in the existing energy storage technology, the wiring distance between a traditional dry-type transformer and a converter and the wiring distance between the traditional dry-type transformer and a high-voltage cabinet are large is solved, and the technical effect of shortening the wiring distances is achieved.

Description

technical field [0001] The invention relates to the technical field of dry-type transformers, in particular to a dry-type transformer coil winding method, a dry-type transformer coil and a dry-type transformer. Background technique [0002] Under the goal of "carbon peaking and carbon neutrality", renewable energy sources such as hydropower, wind energy, and photovoltaics have become important energy technology development routes in my country. Due to the volatility and instability of renewable energy power generation, grid connection may have an impact on the stability of the current grid system, and energy storage systems can solve such problems well. By configuring energy storage in wind and solar power stations, storing the abandoned wind and photovoltaic power of renewable energy and then moving them to other periods for grid connection, not only can the random and fluctuating renewable energy power generation output be smoothly controlled, but also can improve energy ...

AI Technical Summary

Problems solved by technology

[0004] Traditional dry-type transformer primary side, secondary side outlet position is diversified, and the converter or high-voltage cabinet connected to it is limited by its own structure. No matter whether copper bars or cables are used between transformers, converters and high-voltage cabinets Connection, the distance of the wiring is large, resulting in an increase in the amount of materials; in addition, it is difficult to fix and support, and it will also increase the size of the container and increase the cost
