Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0029] This utility model provides a transformer with a novel comb-shaped support bar coil structure. Please refer to [link / reference]. Figure 1 and Figure 2 It includes three-phase coils 1 arranged side by side and iron core 2; upper clamps 3 and lower clamps 4 are respectively provided at the upper and lower ends of the three-phase coils 1; and an insulating cylinder 5 is provided inside each of the three-phase coils 1.

[0030] Please also refer to Figure 3Multiple long comb-shaped support bars 6 are arranged at intervals around the central axis on the side wall of the insulating cylinder 5. Each long comb-shaped support bar 6 extends along the length direction of the insulating cylinder 5 and its two ends extend into the upper clamp 3 and the lower clamp 4, respectively. Multiple short comb-shaped support bars 7 are arranged at intervals around the central axis on the side wall of the insulating cylinder 5. Each short comb-shaped support bar 7 extends along the length direction of the insulating cylinder 5 and its two ends extend into the two end faces of the insulating cylinder 5, respectively.

[0031] Specifically, there are a total of 12 long comb-shaped support bars 6, with four bars configured for each of the three-phase coils 1, evenly distributed around the central axis of the insulating cylinder 5; there are a total of 12 short comb-shaped support bars 7, with four bars configured for each of the three-phase coils 1, and they are staggered among the long comb-shaped support bars 6.

[0032] Furthermore, the insulating cylinder 5 has 8 support bar positions evenly distributed around its central axis; among them, support bar positions 1, 3, 5, and 7 are equipped with long comb-shaped support bars 6, and support bar positions 2, 4, 6, and 8 are equipped with short comb-shaped support bars 7.

[0033] In this embodiment, as Figure 4 As shown, the long comb-shaped support bar 6 has multiple first winding grooves 601 along the axial direction for winding coil wires.

[0034] In this embodiment, as Figure 5 As shown, the short comb-shaped support bar 7 has multiple second winding grooves 701 along the axial direction for winding coil wires.

[0035] For further information, please refer to [link / reference]. Figure 3 The upper clamp 3 and the lower clamp 4 are provided with guide grooves 8 to fix the ends of the long comb-shaped support bar 6 and improve the overall short-circuit resistance of the transformer.

[0036] In this embodiment, the guide groove 8 is movably connected to the upper clamp 3 and the lower clamp 4 to prevent the long comb-shaped support bar 6 from shifting position due to accumulated errors and failing to fully match the guide groove 8.

[0037] In this embodiment, the transformer, based on the original functions of the comb-shaped support bar insulation and fixing the coil, achieves axial positioning of the coil by extending the dimensions of both ends of the comb-shaped support bar and supporting it between the upper and lower clamps, thus replacing the function of the upper and lower yoke pads. By expanding the auxiliary function of the comb-shaped support bar, a new approach and structure for product pressing has been opened up, reducing product materials and inventory, making the product lighter, reducing production costs, and enhancing the company's competitive advantage.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
