Description
Technical Field
[0001] The utility model relates to the technical field of transformer winding auxiliary equipment, in particular to a welding bracket for transformer winding. Background Art
[0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It has the functions of voltage conversion, current conversion, impedance conversion, etc. It is an important link in the transmission, distribution and use of electric energy. In the process of transformer manufacturing, a winding machine is needed to wind the coil inside the transformer to complete the preparation work for transformer manufacturing. Specifically, in the coil winding process, the wire on the pay-off frame, such as copper wire, needs to be wound around the iron core column. When the wire on a pay-off frame is wound, a new pay-off frame must be replaced to continue the winding. At this time, it is necessary to connect the wire on the new pay-off frame with the wire that has been wound on the iron core column. The connection work of traditional transformer winding is generally completed by two people. One person connects one end of the wire on the new pay-off frame with one end of the wire that has been wound on the iron core column, and the other person performs welding. This operation method not only has high labor costs, but also sometimes due to the low quality of manual docking, it is easy to cause unqualified welding and make the coil winding of the entire transformer scrapped. Therefore, it is urgent to improve this situation. Utility Model Content
