Bagaimanakah gegelung pengubah mempengaruhi mesin penggulungan pengeluar mesin penggulungan
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.
Terdapat dua arah pembangunan untuk transformer pada masa hadapan: satu ialah ultra-voltan tinggi, kapasiti besar dan satu lagi ialah kecekapan tinggi, kecerdasan, saiz kecil dan hingar rendah. Sebagai tambahan kepada pengaruh reka bentuk struktur, kualiti dan prestasi ekonomi dan teknikal transformer bergantung pada tahap yang besar pada tahap teknikal proses pembuatan dan peralatan pembuatan. Untuk memenuhi keperluan yang semakin ketat untuk penunjuk kualiti dan prestasi pengubah, pengeluar mesin penggulungan automatik mesti meningkatkan tahap teknikal mesin penggulungan foil pengubah, supaya mereka boleh menghasilkan pengubah yang dapat memenuhi keperluan pembangunan kuasa negara.
Mesin penggulungan menegak semasa dibangunkan lagi ke -skala besar. Mesin penggulungan menegak asal pengeluar mesin penggulungan automatik mempunyai beban hanya 20t, dan ia kini telah dinaikkan kepada 40t. Diameter gegelung lebih besar kepada 3500mm, dan ketinggian yang lebih besar mencapai 4000mm. Peranti ketegangan jenis plat udara-digunakan, dan ketegangan dipaparkan secara digital, dan kawalan ketegangan adalah lebih tepat, stabil dan boleh dipercayai. Untuk meningkatkan ketepatan dimensi luka gegelung, kawal larian jejari mesin penggulungan menegak, dan tingkatkan peranti penetapan kepala aci penggulungan; untuk mengawal pelarian paksi, galas besar jenis penggelek berketepatan tinggi-kepersisan tinggi-digunakan. Oleh itu, melalui penggunaan peralatan khas untuk penggulungan gegelung, pengeluaran penggulungan mencapai tahap yang baru. Ini membolehkan pengubah mengurangkan lagi kerugian, mengurangkan nyahcas separa, mengurangkan berat dan mengurangkan kos.
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.
