METHOD AND DEVICE FOR MAKING A TOROIDAL HEART FOR A TRANSFORMER WITH TOROIDAL HEARTS

摘要

Method and device for the manufacture of a toroidal core of a multiphase transformer having several axially oriented toroidal cores (102). Toroidal cores (102) have phase windings with different phases. The electromagnetic material is wound to obtain a toroidal core, the electromagnetic material is separated when the desired winding height is reached, and the wound toroidal core is fed to the next winding point and then wrapped with electromagnetic material of a different width. When the device is provided, a supporting frame with at least three coil devices with a margin of electromagnetic material having at least two different widths, each, respectively, with a brake device with at least three mustache adhesives for injecting glue, at least three winding devices with a drive system, at least three guiding devices, a guide bar, as well as a cutting device.
