Embodiment

[0016] Refer to attached figure 1 , a transformer tap lead clamping structure, including a pressure plate 2 arranged above the coil 1, a supporting plate 3 arranged below the coil 1, arranged between the pressing plate 2 and the supporting plate 3 and used to connect the tap lead 5 is fixed and led to the clamping column 4 of the switch. The pressure plate 2 includes the first body covering the coil 1 in the axial direction of the transformer and the first connecting portion extending outward from the first body. The supporting plate 3 includes The axial direction of the transformer covers the second body of the coil 1 and the second connecting portion protruding from the second body, and the clamping column 5 connects the first connecting portion with the second connecting portion.

[0017] In this embodiment, the cross-sections of the pressure plate 2 and the support plate 3 perpendicular to the axial direction of the transformer are rectangular. That is to say, while ...

Abstract

The invention relates to a clamping structure for a tapping lead of a transformer, in particular to a clamping structure for a high voltage tapping lead of a transformer. The clamping structure comprises a pressure plate arranged above a coil, a supporting plate arranged below the coil, and a clamping column arranged between the pressure plate and the supporting plate and used for fixing the tapping lead and leading the tapping lead to a switch; the pressure plate comprises a first body covering the coil from the axial direction of the transformer and a first connecting part extending outwards from the first body; the supporting plate comprises a second body covering the coil from the axial direction of the transformer and a second connecting part extending outwards from the second body; and the clamping column is used for connecting the first connecting part with the second connecting part. The purpose of the invention is to provide a clamping structure with the advantages of less parts, simple structure and convenience in installation.

Description

technical field [0001] The invention relates to a clamping structure for tapped lead wires of a transformer, in particular to a clamping structure for high voltage tapped lead wires of a transformer. Background technique [0002] When designing the structure of the transformer, how to lead the high-voltage tap lead wire of the transformer to the switch position after it is drawn out from the coil is also an area worthy of research and improvement. While leading the high-voltage tap leads to the switch, it is also necessary to consider how to arrange the tap leads reasonably and have sufficient strength in a limited space to avoid potential safety hazards. In the prior art, since the pressure plate and the support plate of the coil are circular, and considering the material cost, the cross-sectional area of ​​the pressure plate and the support plate perpendicular to the axial direction of the transformer is generally the same as that of the coil. Therefore, the support plate...
