[0002] The coil of the oil-immersed transformer adopts a layered coil structure, and oil channels are set between some layers of the coil to reduce the temperature of the turns and facilitate ventilation and heat dissipation, thereby meeting the temperature rise conditions of the coil. The oil channel generally adopts a support curtain, such as Figure 2 As shown, the support bar curtain includes two support plates 10 and a plurality of support bars 20. The plurality of support bars 20 are arranged at intervals along the length direction of the two support plates 10 and bonded to the support plates 10 by adhesive. In order to ensure the interlayer insulation of the coil, the support plates 10 and the support bars 20 are both made of insulating materials, wherein the support plates 10 are usually made of epoxy glass plates. The overall support bar curtain is wound between the coil winding layers during assembly to make it firmly combined with the coil. In this way, the interval between two adjacent support bars and the inner and outer windings of the coil form an oil passage for the oil to pass through, which has excellent mechanical strength and electrical performance, increases the mechanical strength of the transformer coil, prevents the coil from deforming and short-circuiting, and can also improve the heat dissipation efficiency of the transformer.
[0003] At present, in the process of making transformer coil support curtains, several support strips are basically manually arranged on the support plate along the length direction of the support plate, and then the several support strips are bonded to the support plate by spraying adhesive. However, the inventor of this application has found through research that when the existing manual arrangement of several support strips on the support plate along the length direction of the support plate is based on manual experience, the spacing of the support strips arranged in this way is not completely consistent, which may affect the electrical performance and heat dissipation effect of the transformer coil support curtain; at the same time, the manual bonding of each support strip and the support plate by spraying adhesive is not only time-consuming and labor-intensive, but also inefficient.

Of course, those skilled in the art can also directly fix the vertical plate 22 to the pillar 24 based on the above embodiments to achieve the above.
[0023] As a preferred embodiment, the number of the vertical plates 22 is multiple, and the multiple vertical plates 22 are vertically stacked on one side of the pillar 24 through the sliding cooperation of the slider and the T-shaped slide groove.
