[0005] However, although the above-mentioned structural design can realize voltage conversion and power transmission between two relatively rotating parts, its structure is complex, and the collector ring is a consumable, which is prone to wear and tear after repeated use. Therefore, the structural design of using transformer and collector ring to provide variable voltage power to rotating parts reduces the reliability of power transmission.

Embodiment approach
[0036] From the above, it can be seen that the rotary transformer equipment provided by the present invention realizes the conduction of the magnetic force lines through the structural design of the stator magnetic conductive plate 32 and the rotor magnetic conductive plate 22 . Therefore, as a preferred implementation manner, the present invention designs the rotor magnetically conductive plate 22 and the stator magnetically conductive plate 32 as ring structures. It can be seen from this structure that no matter how the rotor core 2 rotates, the relative state between the rotor magnetically permeable plate 22 and the stator magnetically permeable plate 32 remains unchanged, thereby achieving stable magnetic conduction.
[0037] In addition, based on the above-mentioned conduction principle of the magnetic field lines, the stator magnetically conductive plate 32 can be designed as a spline structure, and the rotor magnetically conductive plate 22 is still a ring structure, whi...

The invention discloses rotary transformation equipment, which comprises a rotary shaft and a magnetic-conductance portion. The magnetic-conduction portion comprises a stator portion and a rotor portion, the rotor portion consists of a rotor iron core, a rotor winding and a rotor magnetic-conduction plate, and the stator portion consists of a stator iron core, a stator winding and a stator magnetic-conduction plate. The rotor winding is wound on the rotor iron core, and the rotor iron core is provided with the rotor magnetic-conduction plate used for magnetic lines to circulate. The stator winding is wound on the stator iron core, and the stator iron core is provided with the stator magnetic-conductance plate used for magnetic lines to circulate. The rotor magnetic-conduction plate and the stator magnetic-conduction plate are arranged oppositely, so that circulation of the magnetic lines can be realized when the rotor magnetic-conduction plate can be matched with the stator magnetic-conduction plate during rotating. Besides, magnetism can be conducted through the magnetic-conduction plates during rotating of the rotor iron core, voltage transformation is realized, and accordingly, the problem of reliable voltage transformation between two relative-rotation parts in the prior art is solved.
Description
technical field [0001] The invention relates to the technical field of transformer equipment, in particular to rotary transformer equipment. Background technique [0002] A wind power plant is a device capable of converting wind energy into electrical energy and has a nacelle for accommodating a wind turbine. Since wind power generation equipment (hereinafter referred to as wind power equipment) converts wind energy, in order to obtain maximum conversion efficiency, it is required that the fan blades of the wind power equipment can always face the direction of wind blowing. In order to adjust the orientation of the fan blades, the nacelle frame of the nacelle in the prior art is connected to the supporting tower through bearings, and the nacelle frame can realize relative rotation with the supporting tower through the bearings. Since the fan blade is fixedly connected to the fan, and the fan is arranged in the nacelle, the steering adjustment of the fan blade can be realize...
