Kako zavojnica transformatora utiče na mašinu za namotavanje proizvođača mašine za namotavanje
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.
Postoje dva pravca razvoja transformatora u budućnosti: jedan je ultra-visok napon, velikog kapaciteta, a drugi je visoka efikasnost, inteligencija, mala veličina i niska razina buke. Pored uticaja konstruktivnog dizajna, kvalitet i ekonomsko-tehničke performanse transformatora u velikoj meri zavise od tehničkog nivoa proizvodnih procesa i proizvodne opreme. Kako bi ispunili sve strožije zahtjeve za kvalitetom transformatora i pokazateljima performansi, proizvođači mašina za automatsko namotavanje moraju unaprijediti tehnički nivo mašina za namotavanje transformatorske folije, kako bi mogli proizvoditi transformatore koji mogu zadovoljiti potrebe nacionalnog elektroenergetskog razvoja.
Trenutna mašina za vertikalno namatanje dalje je razvijena do velikih-razmjera. Originalna mašina za vertikalno namatanje proizvođača automatskih mašina za namatanje ima opterećenje od samo 20t, a sada je povećana na 40t. Prečnik zavojnice je veći do 3500mm, a veća visina dostiže 4000mm. Koristi se zatezni uređaj tipa vazdušnih jastuka-, a napetost se prikazuje digitalno, a kontrola zatezanja je preciznija, stabilnija i pouzdanija. Kako bi se poboljšala točnost dimenzija namotanih zavojnica, kontrolirajte radijalno strujanje mašine za vertikalno namotavanje i povećajte uređaj za pričvršćivanje glave osovine za namotavanje; Da bi se kontrolisalo aksijalno trzanje, koristi se visoko{6}}precizan dvoredni- veliki ležaj tipa valjkastog tipa. Stoga, korištenjem posebne opreme za namotavanje zavojnica, proizvodnja namotaja dostiže novi nivo. Ovo transformatoru omogućava dalje smanjenje gubitaka, smanjenje djelomičnog pražnjenja, smanjenje težine i smanjenje troškova.
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.
