Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to an automated production transformer structure that meets the needs of large currents. Background Art

[0002] The transformer structures currently on the market cannot meet the requirements for a larger safety distance between the primary and secondary and the demand for large currents. Currently, the windings of conventional transformers are all wound manually using a two-axis machine, which cannot be produced automatically and has low efficiency. Even if the windings are wound by the same person, the parasitic parameters of the transformers produced are complex, and the consistency of leakage inductance, DCR, and size is also very poor. The consistency of these characteristics is even worse between transformers wound by different people.

[0003] The existing transformers have conventional windings that are all wound manually using a two-axis machine, which cannot be produced automatically and is inefficient. In addition, the parasitic parameters of manually produced transformers are complex. Therefore, an automated production transformer structure that can meet the needs of large currents is needed.

[0005] To achieve the above objectives, the utility model provides the following technical solutions: an automated production transformer structure that meets the requirements of large currents, comprising a primary winding, a secondary winding installed below the primary winding, and an isolation component threadedly connected between the primary winding and the secondary winding.

[0006] Preferably, the primary winding comprises a first BBN and a first threaded end, and the end of the first BBN is integrally provided with the first threaded end.

[0012] 1. By setting the primary winding, the first BBN and the second BBN are isolated by an isolation device, which can meet the larger safety distance requirements between the primary and secondary. The primary winding can use a coil with a thicker wire diameter. The coil here can be a three-layer insulated wire or not, so as to pass a larger current and realize the automation of the primary winding. The secondary winding can use a flat coil, a multi-turn synthetic copper sheet, etc., wherein the turns of the copper sheet are isolated by insulating materials such as tape and NOMEX, so as to pass a larger current and realize the automation of the secondary winding. The primary and secondary are isolated by an isolation device. The length of the isolation device can be adjusted and the isolation devices of different specifications can be replaced to meet the leakage inductance requirements with large values, which is particularly suitable for the large leakage inductance requirements of LLC. The BBN manufacturer sets the threaded end at the appropriate position on the first BBN and the second BBN, and the isolation device is assembled to the corresponding position through the upper and lower threaded ends, so that the leakage inductance can be controlled more accurately.
