The description of SCB11 full copper dry-type transformer
The SCB11 full copper dry-type transformer produced by ZTELEC uses a new insulation structure to improve the short-circuit resistance; the iron core is made of high-quality cold-rolled silicon steel sheet; high-voltage windings are made of high-quality oxygen-free copper wire as the material. And adopts multilayer cylindrical structure; all fasteners are treated with special relaxation.
The SCB11 full copper dry-type transformer has the characteristics of high efficiency and low loss which can save a lot of power consumption and operating costs that has significant social benefits.SCB11 full copper dry-type transformer is a high-tech product promoted by the country.
The features of SCB11 full copper dry-type transformer
The low-voltage coil of SCB11 full copper dry-type transformer is directly detoured on the high-strength bobbin. The high, low, and pressure-regulating coils are compressed in the radial and axial directions during winding. The outer diameter side adopts locking braces to increase the radial direction.
The coil of SCB11 full copper dry-type transformer is dried by pressure and vacuum and is completely assembled. During the reassembly process, the coil height is adjusted repeatedly to ensure that the height of the high and low voltage regulating coils is completely consistent, that is, the coil is processed stably. All the pads are pre-densified, chamfered and deburred and evenly compress the parts of the body to ensure the mechanical strength and sufficient pressing force to improve the axial strength of the coil.
When winding high-voltage, low-voltage, and voltage-regulating coils, ensure that the geometric dimensions of the coils are accurate, and that the dimensions of each coil in the assembly center are closely matched with each other. The sleeve adopts a series of combined processes to bind and support in the radial direction, and the parts will not shift or deform when subjected to short-circuit electric force.
The lead wire of SCB11 full copper dry-type transformer is fixed and strengthened and the components adopt self-locking and anti-loose structure to meet the dynamic thermal stability during short circuit.
The coil radial tightening of SCB11 full copper dry-type transformer adopts the “zero” margin design. The core and the low-voltage coil paper tube, the low-voltage, high-voltage, the voltage-regulating coil, and the brace and the surrounding board are fully and uniformly dried to ensure close cooperation and guarantee. The entire coil has excellent tightness and concentricity.
Insulating materials of SCB11 full copper dry-type transformer adopt strict and standardized dry and sealed storage at all stages of raw materials, semi-finished products and assembled bodies to avoid uncontrollable moisture expansion and deformation and dimensional changes, such as insulating cardboard, post-processing pads, crimping rings, etc. All are placed in a dedicated constant temperature drying cylinder in a sealed storage.
