The gap may cause insufficient contact between the bar and the core, increase contact resistance, and may cause problems such as discharge of the bar to the core. In order to fill gaps between the iron cores and the bars, semiconductor putty is generally adopted for shaping, the semiconductor putty with a certain thickness is uniformly coated on the slot lining paper, the bars are wrapped by the slot lining paper, and the bars are extruded through the iron cores during wire drawing, so that the semiconductor putty fully fills gaps between the iron cores and the bars, and the slot potential is reduced.
The existing device for wrapping the slot paper on the stator bar of the water turbine is clumsy and has low automation degree, for example, chinese patent document CN 213637407U describes a special device for wrapping the slot paper on the stator bar of a large-scale hydroelectric generator, a sliding rail is arranged on a base and is in sliding connection with a scraper bracket, and a scraper blade is fixed on the scraper bracket; a three-fold type fixed bottom plate is arranged on the base and is positioned below the scraping blade; the two ends of the three-fold fixed bottom plate are provided with wire rod clamping grooves which are fixed on the base.
The device mainly carries out the operation of scraping glue and winding bar parcel to the wrapping paper through the device frock, and at the preface of scraping glue and winding bar, still need measure the wrapping paper, tailor and the process of unloading for the whole process still needs more manual work like this, does not have dedicated wrapping paper unloader yet.
