AI Technical Summary

Technical Problem

Existing high-frequency transformers are prone to distributed capacitance and leakage inductance when the conductor diameter of the secondary winding is small and the number of turns is large, resulting in heat generation, high losses, unstable operation, and easy damage.

Method used

Two sets of U-shaped magnetic cores are connected to the inner hole of the primary side frame. The primary and secondary windings are coaxially assembled and fixed by insulating isolation rings and fastening devices to reduce eddy current losses and improve transformer efficiency.

Benefits of technology

It effectively avoids magnetic saturation, improves the transformer's high voltage and high temperature resistance, reduces eddy current losses, and ensures the transformer's stability and efficient operation.

Abstract

This utility model relates to a transformer, and more particularly to a high-frequency transformer device. The high-frequency transformer device includes a secondary frame, a secondary winding, an insulating isolation ring, a secondary positioning tube, a primary winding, a primary frame, U-shaped magnetic cores, and insulating blocks. Two sets of U-shaped magnetic cores are provided, each set placed on the insulating blocks. The two ends of the primary frame are respectively fitted onto the vertical beams of each set of U-shaped magnetic cores. The secondary positioning tubes are respectively fitted onto the outer sides of both ends of the primary frame and engage with the corresponding U-shaped magnetic core beams. The insulating isolation ring and the secondary frame are sequentially installed on the primary frame, with the insulating isolation rings on both sides engaging with the corresponding secondary positioning tubes. This utility model effectively avoids magnetic saturation by connecting the two sets of U-shaped magnetic cores to the inner hole of the primary frame; and improves transformer efficiency and reduces eddy current losses by coaxially assembling the primary and secondary windings.
