OEM High Quality Transformer Product Selection Manufacturers – S- M. L Series Of Oil Immersed Power Transformer With Three Dimensional Wound Core – Changan Group Detail:

Product introduction

S □ -M·L series three-dimensional wound core oil immersed transformer produced by the company is a new generation transformer product with more reasonable structure, lower operation noise, better performance and stronger reliability. The product breaks through the traditional plane structure and adopts three-phase symmetrical three-dimensional structure. The three cores are arranged in an equilateral triangle, and the length of the three magnetic circuits is consistent. It has the characteristics of high efficiency and low loss. It can save a lot of power consumption and operating costs, and has significant social benefits. It has been widely used in power plants, substations, industrial and mining enterprises, ports, airports and other places.

Product characteristics

Optirmoizdeud: the three-phase magnetic circuit length of three-dimensional wound core is completely equal, the sum of the three-phase magnetic circuit length is the shortest, the three-phase magnetic circuit is completely symmetrical, and the three-phase no-load current is completely balanced.
2.Low loss and remarkable energy-saving effect: the magnetization direction of three-dimensional coil core is completely consistent with the rolling direction of silicon steel sheet, the magnetic flux distribution is uniform throughout the magnetic circuit, and there is no obvious distortion of magnetic flux density in high resistance area and joint. On the premise of the same material, the process coefficient of core loss is significantly lower than that of laminated core, the core loss can be reduced by 10% – 20%, and the no- load loss can be reduced by 25% – 35%.
3.Low noise: as the three-dimensional core is made of silicon steel strip in a special core winding machine, there is no seam, so it will not produce the noise caused by the magnetic circuit discontinuity as the laminated core. Therefore, the voice of the product is greatly reduced, almost reaching the state of environmental protection mute, which is most suitable for indoor and residential use.
4.Strong overload capacity: the no-load loss and no-load current of this type of transformer are very small, so the calorific value of the product itself is very low; in addition, the three-phase coils are arranged in three rectangle structure, forming a central natural airway – “exhaust chimney” between the coils. Because the temperature difference between the upper and lower yokes is 30-40 ℃ , strong air convection is generated, and the cold air flows from the bottom to the central passage in addition, the heat radiates out from the inner slope of the upper yoke, and the heat generated by the transformer is quickly taken away in the natural circulation.
5.Compact structure and small occupation: the three-dimensional iron core makes the product compact in structure, the plane occupation area of the body is reduced by 10-15% compared with the traditional products, and the body height is reduced by 10- 20%.
