Product description
SCB10-1250KVA dry-type transformer is made of high-quality materials and advanced production and testing equipment according to strict technology. It is a dry-type transformer with high electrical strength, mechanical strength and heat resistance. It is the most advanced product of urban power grid transformation, The product has the characteristics of high reliability and long service life. It is suitable for high-rise buildings, commercial centers, residential quarters, hospitals, chemical plants, nuclear power plants, ships and other important or special environmental places such as power distribution networks and power supply and distribution systems of industrial and mining enterprises that require fire prevention, explosion proof and moisture protection. Different protection levels can be configured according to different usage environments. SCB10-1250KVA dry-type transformer can be equipped with temperature control and temperature display system according to user needs, and can be used with temperature control system.
Because our company’s SCB10-1250KVA dry-type transformer has the above characteristics, it is widely used in power transmission and transformation systems, such as hotels, restaurants, airports, high-rise buildings, commercial centers, residential areas and other important places, as well as subways, smelting power plants, ships, offshore drilling platforms and other harsh environmental places.
Core
The core is made of imported high-quality cold-rolled silicon steel sheet, the core is made of imported high-quality cold-rolled silicon steel sheet, the final structure of the full miter, the core column is tied with F-grade non-weft adhesive tape, and the surface of the core is encapsulated with epoxy resin, which reduces the no-load loss, no-load current and core noise, and the clamps and fasteners are specially treated with special surface treatment, so that the appearance quality of the product has been further improved.
High voltage windings
High-voltage winding high-voltage winding with packing ring resin vacuum casting, greatly reducing the amount of partial discharge, improving the electrical strength of the coil, the inner and outer walls of the winding are filled with fiberglass grid plates, enhancing the mechanical strength of the coil, improving the ability of the product to resist sudden short circuit, coil cracking.
Low-voltage windings
The low-voltage winding adopts a foil structure, which solves the problem of axial helix angle when winding with wire, and makes the ampere turn more balanced, while the coil adopts an axial cooling air duct to enhance the heat dissipation capacity, and TD is used between the winding layers Positive epoxy resin prepreg, cured and formed as a whole.
Manufacturing process
The coil is wound on the high-precision winding machine, the low-voltage winding adopts the foil winding structure, the transformer has a large capacity, and the vacuum drying is carried out after the ventilation channel is completed, and the whole pouring and curing process is operated in full accordance with the process requirements, all processes need to be strictly monitored, and the precision manufacturing process of mouth pouring is adjusted according to the situation so that the coil is free of bubbles and holes, so that the transformer made can achieve high-quality operation effect.
Temperature control system and air cooling system
The cross-flow top blowing cooling fan is adopted, which has the characteristics of low noise, high air pressure and beautiful appearance, which enhances the overload capacity of the transformer. The temperature control adopts an intelligent thermostat to improve the safety and reliability of transformer operation.
Features:
1. Low loss, good power-saving effect, bringing economic benefits to operation.
2. Flame retardant, explosion-proof, pollution-free, maintenance-free, can be dispersed and installed in the load center, reducing investment cost and saving costs.
3. The partial discharge amount is less than 10PC, the coil does not absorb moisture, does not absorb dust, has high mechanical strength and good reliability.
4. Anti-short circuit, good resistance to lightning impact.
5. The shell is made of three materials: stainless steel, cold plate and aluminum alloy, the type is divided into wind type and heat dissipation type, and the inlet and outlet lines can be up and down, down and out, and down and down.
6. The transformer can be equipped with temperature control and temperature display system according to user needs, and can be used with temperature control system.
