Description

Technical Field

[0001] The present invention relates to the technical field of transformer processing, and particularly relates to an electric constant-tension foil winding machine. Background Art

[0002] A transformer is an electrical device used to change the AC voltage, and generally includes one or more windings and an iron core. Through the transformer, the voltage can be transferred from one circuit to another while changing the magnitude of the voltage. A three-winding transformer is a type of transformer. Each phase of the three-winding transformer has three windings, and the high, medium, and low voltage windings of each phase are all sleeved on the same iron core column; when one winding is connected to an AC power supply, different electromotive forces are induced in the other two windings. This type of transformer is used for loads that require two different voltage levels. Three different voltage levels usually appear in power plants and substations, so three-winding transformers are widely used in the power system.

[0003] In a three-winding transformer, the high-voltage winding, medium-voltage winding, and low-voltage winding are all wound around the iron core by a winding machine. The winding usually includes insulating paper, copper foil, and separator tape wound in sequence. In a conventional winding machine, the material tray of the separator tape is installed on the top of the machine. When changing the material, it is necessary for workers to climb to the top of the machine to change the material, which is difficult and has a large potential safety hazard.
