Winding mechanism for concentric winding of oil-immersed transformer and application of winding mechanism

Abstract

The invention relates to the technical field of oil-immersed transformers, and discloses a winding mechanism for a concentric winding of an oil-immersed transformer and application of the winding mechanism. The winding mechanism comprises an iron core, wherein the top of the iron core is fixedly connected with a mercury box; an extrusion plate is connected into the mercury box in a sliding manner;the bottom of the extrusion plate is fixedly connected with a force storage rod; the side face of the force storage rod is in engaged connection with a bearing wheel; the surface of the bearing wheelis connected with a screw in a meshed mode; the side face of the screw is connected with a rotating shaft in a meshed mode; the side face of the force storage rod is slidably connected with an extrusion rod; the right side of the extrusion rod is rotatably connected with a driving wheel; a meshing rod is arranged on the side face of the driving wheel in a penetrating mode; and a conical shaft isarranged below the driving wheel. According to the winding mechanism for the concentric winding of the oil-immersed transformer and the application of the winding mechanism, through cooperative use ofthe mercury box and a cutting frame, the effect of automatically compensating leaked electric energy for a load when the magnetic flux leakage phenomenon affects work of the transformer is achieved.

Description

technical field [0001] The invention relates to the technical field of oil-immersed transformers, in particular to an oil-immersed transformer concentric winding winding mechanism and its application. Background technique [0002] Oil-immersed transformer is a new type of high-performance transformer with more reasonable structure and better performance. The three-dimensional wound iron core has three-dimensional arrangement of equilateral triangles, so there is no air gap in the magnetic circuit and the winding is more compact. , the three magnetic circuits have the same length and are the shortest. The cross-sectional area of ​​the iron core is closer to a circle, so the performance is further improved, the loss is reduced, the noise is reduced, the three items are balanced, and the third harmonic component is reduced. [0003] When the transformer is working, because there are certain gaps in the winding wires wound on the surface of the iron core, when these windings gen...
