Hvordan påvirker transformatorspolen viklingsmaskinen hos producenten af viklingsmaskinen
As my country's economy develops rapidly and steadily, the demand for electricity is also increasing. As the basic equipment for power transmission and transformation in the power industry, transformers are widely used in power plants, converter stations, substations and user terminals. They occupy a very important position in the power industry. Their demand is also increasing day by day, and the market prospect is very broad. This puts forward higher requirements for the production efficiency of transformers in our country. At the same time, with the global energy crisis, it is imperative to produce more energy-efficient and efficient transformers. It is in this context that my country's transformer manufacturing standards are repeatedly raised, and the requirements for performance indicators are becoming more and more stringent.
Der er to udviklingsretninger for transformere i fremtiden: Den ene er ultra-høj spænding, stor kapacitet, og den anden er høj effektivitet, intelligens, lille størrelse og lav støj. Ud over indflydelsen af strukturelt design afhænger transformatorernes kvalitet og økonomiske og tekniske ydeevne i vid udstrækning af det tekniske niveau af fremstillingsprocesser og fremstillingsudstyr. For at opfylde de stadigt strengere krav til transformatorkvalitet og ydeevneindikatorer skal producenter af automatiske viklingsmaskiner forbedre det tekniske niveau af transformerfolieviklingsmaskiner, så de kan producere transformere, der kan imødekomme behovene for national kraftudvikling.
Den nuværende vertikale viklemaskine er videreudviklet til stor-skala. Den originale vertikale viklemaskine fra producenten af automatiske viklemaskiner har en belastning på kun 20t, og den er nu øget til 40t. Diameteren af spolen er større til 3500 mm, og den større højde når 4000 mm. Spændingsenheden af airbagplade-typen bruges, og spændingen vises digitalt, og spændingskontrollen er mere nøjagtig, stabil og pålidelig. For at forbedre dimensionsnøjagtigheden af de viklede spoler skal du kontrollere den radiale udløb af den lodrette viklingsmaskine og øge fastgørelsesanordningen til viklingsakslens hoved; for at kontrollere det aksiale udløb, bruges et stort leje af høj-præcision dobbelt-rulletype. Derfor, gennem brug af specialudstyr til spolevikling, når viklingsproduktionen et nyt niveau. Dette gør det muligt for transformeren yderligere at reducere tab, reducere delvis afladning, reducere vægt og reducere omkostninger.
From the transformer winding structure design, not all the coils can be used in the production of vertical winding machine. Such as layer structure, multi-spiral structure coil. If this coil is wound using a common horizontal winding machine, axial no pressure winding system, line segment gap is large, like a pressure spring. The diameter of the coil becomes larger after pressing, and the gap between the coil and the paper tube will cause the axial instability of the coil, the coil may be damaged in the case of Axial Electric Force. Therefore, with axial, radial compression type horizontal winding machine, in the production of large transformer coil, has been widely used. Along with the transformer performance request is more and more high, the General Small and medium-sized transformer's production, also gradually starts to use the compression type horizontal winding machine. In order to control the pressing force more accurately, the torque motor or cylinder used in the pressing mechanism has been replaced by servo motor. In order to control the size tolerance of the winding coil, increase the grating ruler, on-line detection coil size. According to the length of the winding coil, the tension of each spool can be controlled independently, and the follow-up of the Spool can avoid the new stress caused by the distortion of the wire and reduce the eddy current loss of the winding.
