S13-M.RL series three-dimensional magnetic circuit transformer

The description of S13-M.RL series three-dimensional magnetic circuit transformer

The S13-M.RL series three-dimensional magnetic circuit transformer breaks through the traditional planar structure and adopts a three-phase symmetrical three-dimensional structure. The three-phase iron core magnetic circuit of the S13-M.RL series three-dimensional magnetic circuit transformer is completely symmetrical. The magnetic resistance is greatly reduced, the excitation current and no-load loss are significantly reduced. A high-efficiency energy-saving transformer that uses traditional materials, but has lower operating noise and a more compact structure. Its outstanding performance in energy saving, material saving and environmental protection fully meets the energy saving and low carbon requirements advocated by China.

The core of the S13-M.RL series three-dimensional magnetic circuit transformer is composed of a three-phase cylindrical yoke with a single frame and a three-dimensional triangular arrangement. Each cylinder is continuously rolled by high-quality cold-rolled silicon steel strip and the bandwidth is cut by straight or curved lines by a CNC opener. The strip is wound on an iron core winding machine to form a nearly circular or folded edge arc frame, and then processed by vacuum nitrogen annealing to process the stress, reorient the lattice, improve the magnetic permeability that improve the electromagnetic performance; special winding for high and low voltage coils. The winding machine is wound on the iron core paper tube. The overall structure is solid and compact. The body uses upper and lower iron yoke insulation and laminated wood. The screw is tightened around the coil to make it stable and able to withstand the impact of sudden short circuit force. S13-M.RL series three-dimensional magnetic circuit transformer has the characteristics of low no-load loss, low no-load current, low noise, and significant power saving effect. It improves the voltage quality and the reliability of power supply. It is a green energy-saving device that is conducive to environmental protection and a new product that is promoted and used in the technical transformation project of urban and rural power grids.
