Description

Technical Field

[0001] The utility model relates to a transformer lead extension support fixing structure, belonging to the technical field of transformer manufacturing. Background Art

[0002] In the field of transformer manufacturing technology, the transformer lead fixing method is generally as follows: the fixing plate welded on the core clamp uses the transformer lead wire clamp (existing technology) to cooperate with the fixing plate to support and fix the transformer lead. However, due to the obstruction of metal parts such as the drawstring on the core clamp at the transformer lead, the fixing plate welded at the core clamp position often cannot cooperate with the lead wire clamp, and the position of the transformer lead wire clamp needs to be staggered to support and fix the transformer lead. Utility Model Content

[0003] The purpose of the utility model is to provide a transformer lead extension support fixing structure. When clamping the transformer lead, the fixing plate at the clamp is welded to the core clamp, and an extended support fixed wire clamp is added at the lead wire clamp to avoid metal parts such as the core clamp pull strap, so as to achieve lead fixing at the core clamp pull strap position, thereby solving the above-mentioned technical problems existing in the prior art.

[0004] The technical solution of the utility model is:

[0005] A transformer lead extension support fixing structure comprises an oil tank bottom, a fixing plate at a clamp, a wire clamp, a lead wire clamp, an iron core clamp, a vertical pole, a metal fastener, an insulating screw nut and an adjusting pad. The inner end of the fixing plate at the clamp is welded to the iron core clamp, the fixing plate at the clamp extends horizontally away from the iron core pull strap on the iron core clamp, and the outer end of the fixing plate at the clamp is fastened to one end of the lead wire clamp by a metal fastener; the bottom of the wire clamp is vertically supported on the oil tank bottom, the upper part of the wire clamp is a step structure, and the step structure holds up the other end of the lead wire clamp; the top of the wire clamp is fastened to the vertical pole by an insulating screw nut; an insulating adjusting pad is arranged between the bottom of the wire clamp and the oil tank bottom.

[0006] The outer end of the clamp fixing plate is provided with a reserved hole, and the metal fastener fastens the clamp fixing plate and the lead wire clamp through the reserved hole; the metal fastener includes a metal bolt, a nut and a washer.

[0007] A through hole is arranged on the top of the wire clamp, and the wire clamp is fastened and connected to the vertical pole through an insulating screw nut.

[0008] By adopting the present utility model, a fixing plate at the clamp part is welded on the core clamp. The fixing plate at the clamp part extends away from metal parts such as the core tie strap. The wire clamp is supported on the bottom of the fuel tank. The lead wire clamp is supported by the vertically arranged wire clamp. The adjusting pad is used to adjust the support height of the wire clamp. The top of the wire clamp is connected to the vertical rod to increase strength, playing a role in supporting and fixing the transformer lead at the position of the core tie strap.

[0009] Positive effects of the present utility model: When clamping the transformer lead, the fixing plate at the clamp part is welded on the core clamp. An additional wire clamp for extended support and fixation is added at the lead wire clamp, avoiding metal parts such as the core clamp tie strap, and realizing lead fixation at the position of the core clamp tie strap.
