A transformer structure that can withstand high frequency and high current while meeting a large ampere distance.

Abstract

This utility model provides a transformer structure that can withstand high frequency and high current and meet a large ampere distance. It adopts a secondary winding composed of three-layer insulated Litz wire. The Litz wire busbar is thinner and has more strands, which can withstand high frequency and high current. The wires are delivered through a base plate fixed at the bottom of the frame. The primary winding uses ordinary insulated wire and is delivered through the pins of the frame, which increases the safety distance between the primary and secondary windings and ensures the safety of transformer use.

Description

Technical Field

[0001] This utility model belongs to the field of transformer technology, specifically relating to a transformer structure that can withstand high frequency and large current and meet a large ampere distance. Background Technology

[0002] Current transformer structures typically employ the Litz wire-wound pin method, which is difficult to withstand high-frequency, high-current applications, affecting current carrying capacity. It also causes problems such as pins being easily bent, affecting the transformer plug-in board, and high wire ends and uneven bonding. Furthermore, the safety distance between the primary and secondary windings is relatively small.

[0003] Meanwhile, conventional transformer structures have difficulty effectively dissipating heat into the air, often resulting in excessive temperature rise. Furthermore, the top shape of conventional transformers is irregular and cannot meet the customer's requirements for automated grasping. Therefore, a transformer structure that can withstand high frequency and high current and meet a large ampere distance is needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a transformer structure capable of withstanding high-frequency, high-current conditions and meeting a large ampere distance. The structure includes a frame, on which a magnetic core is fixedly mounted to generate magnetic flux. A primary winding and a secondary winding are wound around the frame. A base plate is fixedly mounted at the bottom of the frame. The secondary winding uses Litz wire and exits through the base plate, with the exit end of the secondary winding fixed to the base plate. The primary winding exits through the pins of the frame, thus achieving a large ampere distance between the primary and secondary windings.

[0005] Preferably, both the transformer and the frame have regular shapes, which are suitable for automated handling during transformer production.

[0006] Preferably, the secondary winding uses triple-insulated Litz wire, which can withstand high-frequency and high-current conditions.

[0007] Preferably, the magnetic core is exposed to the air, which provides a large heat dissipation area, allowing the transformer to dissipate heat quickly and maintain good temperature rise characteristics.

[0008] This utility model has the following beneficial effects:

[0009] 1. This utility model adopts a secondary winding composed of three layers of insulated Litz wire, and the wires are output through the bottom plate at the bottom of the frame, which can withstand high frequency and large current, thus improving the current carrying capacity of the transformer.

[0010] 2. This utility model achieves a larger safety distance between the primary and secondary windings by fixing the secondary winding to the base plate and having the primary winding lead out from the PIN pin. At the same time, fixing the secondary winding to the base plate ensures that all pins are fixed, making it less prone to bending and very convenient for subsequent plug-in use.

[0011] 3. The shape and size of the transformer of this utility model are consistent with the frame. The overall shape is a relatively regular and flat cuboid, which can realize automated grasping in transformer production.

[0012] 4. This utility model increases the heat dissipation area and improves the heat dissipation speed of the transformer by exposing the magnetic core to the air, thus enabling the transformer to maintain good temperature rise characteristics. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-4 As shown, this utility model provides a transformer structure that can withstand high frequency and large current and meet a large ampere distance. It includes a frame 1, on which a magnetic core 2 in the shape of ETD is fixed and exposed to the air to improve the heat dissipation speed of the transformer. The secondary winding 3 on the frame 1 uses triple-insulated Litz wire, which can withstand high frequency and large current. The primary winding 4 uses ordinary enameled wire.

[0020] The bottom of the frame 1 is fixedly connected to the base plate 5, which has mounting holes. The secondary winding 3 is led out through the mounting holes on the base plate 5. The lead-out end is fixed to the base plate with glue to fix all the pins, making it less prone to bending and convenient for subsequent plug-in use. The primary winding 4 is led out through the pins on the frame 1, which increases the safe distance between the primary winding 4 and the secondary winding 3, ensuring the safety of the transformer.

[0021] like Figure 2 As shown, the transformer provided by this utility model is a relatively regular, flat-surfaced cuboid, with the same dimensions as the frame 1, which can meet the automated gripping requirements of transformer production.
