A multi-module multi-winding high-frequency transformer assembly and system with ventilation and cooling structure, wherein the auxiliary mechanical support structure is arranged in the outer insulating sleeve; there are two cooling fans, which are respectively arranged at the bottom and top inside the outer insulating sleeve ; The multi-winding high-frequency transformer is arranged on the auxiliary mechanical support structure. The auxiliary mechanical support structure includes several layers of symmetrical three-column mechanical structures, where the number of layers is determined by the number of multi-winding high-frequency transformers. The invention integrates a plurality of multi-winding transformers and ventilation and cooling, and solves the problems of modular design and integrated manufacturing; for multi-module multi-winding high-frequency transformer components, it solves device integration, lead insulation and external circuit connection interface, ventilation and heat dissipation, etc. Key issues, improve cooling effect and reduce system volume. Fans are installed at the bottom and top, and the air volume is fully utilized in the outer insulating sleeve, which solves the problem of increased coil loss due to the diffuse magnetic field caused by the air gap of the magnetic core of the high-frequency transformer.

Description

technical field [0001] The invention relates to the technical field of high-frequency transformers, in particular to a multi-module multi-winding high-frequency transformer assembly and system with a ventilation cooling structure. Background technique [0002] Power transformers are one of the main equipment in power plants and substations. The role of the transformer is multifaceted. It can not only increase the voltage to send electric energy to the power consumption area, but also reduce the voltage to the voltage of all levels to meet the needs of power consumption. In short, both step-up and step-down must be done by the transformer. In the process of electric energy transmission in the power system, two parts of voltage and power will inevitably be lost. When the same power is transmitted, the voltage loss is inversely proportional to the voltage, and the power loss is inversely proportional to the square of the voltage. Using the transformer to increase the voltage ...
