Description

Technical Field

[0001] The invention relates to the technical field of mutual inductor production and preparation, and specifically discloses a mutual inductor production device. Background Art

[0002] The instrument transformer is an indispensable part of power facilities, which is mainly divided into current transformer and voltage transformer. However, both current transformer and voltage transformer need to be wound on the transformer core during the production process. At present, the winding process of the instrument transformer during the production process is completed by a semi-automatic winding machine. Although the existing semi-automatic winding machine has a good winding effect, the loading and unloading of the core after winding are both manually operated, which not only increases the labor intensity of the operators, but also affects the winding efficiency of the transformer core.

[0003] For example, the invention patent with application number 2015109700136 discloses an automatic winding machine and winding method for the secondary winding of a current transformer. The automatic winding machine includes a box, a core station clamping device installed on the upper end surface of the box, a secondary winding winding ring device, a winding coil counter and a hand-cranked device arranged in the box; the automatic winding machine uses the core station clamping device, and then can adjust the core clamping station according to the size of the current transformer core, and then use the secondary winding winding ring device to make the copper wire wound on the core arranged evenly and uniformly, and the tension is consistent. The automatic winding machine for the secondary winding of the current transformer is actually a semi-automatic winding machine. When winding the core of the transformer, it is necessary to manually put the core into the station clamping device, and after the winding is completed, it is also necessary to manually take the core of the transformer out of it, which is not only cumbersome, but also makes the winding efficiency of the transformer core low. In addition, the workpiece of the current transformer secondary winding automatic winding machine is fixed during winding, so it is impossible to evenly wind a layer of copper wire on the transformer core, resulting in poor performance of the prepared transformer in various aspects. Therefore, in view of the above-mentioned shortcomings of the existing current transformer secondary winding automatic winding machine, the present invention proposes a transformer production equipment, which can effectively solve the technical problems existing in the transformer winding process.

[0018] (1) When the transformer production equipment disclosed in the present invention performs winding processing on the core ring of the transformer, the core ring loading device and the unloading guide rail can place one core ring on the two positioning wheels at a time, and then the core ring can automatically rotate slowly during the winding process through the pressing and driving action of the driving wheel.
