The description of SCB10 35kV resin insulated dry-type transformer
SCB10 35kV resin insulated dry-type transformer are our company's introduction of foreign advanced technology and independently developed SC9, SCB9 series and SC1O, SCB1O series of thin-film insulation dry-type transformers with fillers. Because the coil of SCB10 35kV resin insulated dry-type transformer is encapsulated by epoxy resin that is flame-resistant, fire-proof and explosion-proof Maintenance-free, pollution-free, small size, can be directly installed in the load center. At the same time, the scientific and reasonable design and casting process make the product have a smaller partial discharge, low noise and strong heat dissipation capacity. SCB10 35kV resin insulated dry-type transformer can run for a long time at 140% of the rated load under forced air cooling and is equipped with an intelligent temperature controller with failure. Alarm, over-temperature alarm, over-temperature trip and black brake function, and connected to the computer through RS485 serial interface that can be centrally monitored and controlled.
The SCB10 35kV resin insulated dry-type transformer produced by ZTELEC have the above characteristics, so they are widely used in power transmission and transformation systems, such as hotels, airports, high-rise buildings, commercial centers, residential areas and other important places, as well as in subways, smelting power plants, ships, offshore drilling platforms and other environments harsh places.
The structure of SCB10 35kV resin insulated dry-type transformer
The core of SCB10 35kV resin insulated dry-type transformer is made of imported high-quality cold-rolled silicon steel sheet. The core is made of imported high-quality cold-rolled silicon steel sheet, with a full miter end structure, the core is bound with F-level weft-free adhesive tape, and the core surface is encapsulated with epoxy resin to reduce no-load loss and core noise. The clips and fasteners are treated with a special surface, which further improves the appearance quality of the product.
High-voltage windings of SCB10 35kV resin insulated dry-type transformer are filled with vacuum resin with a filler ring which greatly reduces the amount of partial discharge and improves the electrical strength of the coil. The inner and outer walls of the winding are filled with glass fiber grid plates which enhances the mechanical strength of the coil and improves the product's anti-burst. The ability to short-circuit, the coil will never crack.
The low voltage windings of SCB10 35kV resin insulated dry-type transformer adopt a foil structure which solves the problem of the axial helix angle when using wire winding to make the ampere turn more balanced. At the same time, the coil uses an axial cooling air duct to enhance the heat dissipation ability.
The manufacturing process of SCB10 35kV resin insulated dry-type transformer
The coil is wound on a high-precision winding machine. The low-voltage winding of SCB10 35kV resin insulated dry-type transformer uses a foil winding structure. When the transformer has a large capacity, it is dried after the air duct is wound. The entire casting and curing process is performed according to the process requirements. There is strict monitoring, and the precise manufacturing process of the pouring of the adjustment port is carried out according to the situation, so that the coil is free of air bubbles and cavities, so that the finished transformer can achieve high-quality operation results.
