5.JB / T10088-2004 6 ~ 500kV transformer sound level

6.JB / T56009-1998 quality classification of SCB10-3150 large-scale dry-type transformers

The features of SCB10-3150 large-scale dry-type transformers

SCB10-3150 large-scale dry-type transformers have fully sealed and fully insulated structure and no insulation distance required, reliable protection of personal safety. The cable head has two types: 200A elbow plug and 600A “r” type fixed cable connector. Both can be equipped with the function of a fully insulated zinc oxide arrester isolation switch.

Compared with SCB9 type,SCB10-3150 large-scale dry-type transformers has lower no-load loss, no-load current and noise.

SCB10-3150 large-scale dry-type transformers are safe, fireproof, non-polluting, can be directly operated in the load center.

SCB10-3150 large-scale dry-type transformers have high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability and long service life.

Good heat dissipation performance, strong overload capacity, can increase capacity operation when forced air cooling;

Good moisture resistance of SCB10-3150 large-scale dry-type transformers is suitable for operation in high humidity and other harsh environments.

SCB10-3150 large-scale dry-type transformers can be equipped with a complete temperature monitoring and protection system, using an intelligent signal temperature control system which can automatically monitor and display the respective working temperature of the three-phase windings on the same screen that can automatically start and stop the fan, and have alarm, trip and other functional settings.

The good structures of SCB10-3150 large-scale dry-type transformers

The core material is made of high-quality cold-rolled oriented silicon steel sheet, with full oblique seam laminated structure;

The low-voltage coil is a foil-type winding structure, which is wound with high-quality copper foil, the high-voltage coil is a layered structure, and vacuum epoxy casting is used.

High voltage winding

Filled epoxy resin of SCB10-3150 large-scale dry-type transformers is used for high-voltage winding vacuum casting, small partial discharge, high coil electrical strength, reinforced with fiberglass network grid around the inner and outer walls, increasing the mechanical strength of the coil, improving the product's ability to resist sudden short circuits, and the coil never cracking.

Low voltage winding

The low-voltage winding of SCB10-3150 large-scale dry-type transformers adopts a foil structure, which solves the problem of the axial helix angle when using wire winding, making the turns more s. At the same time, the coil uses an axial cooling air duct, which enhances the ability to resist heat. The winding layer uses DMD epoxy pre-diffusion. , The overall solidification.

The core of SCB10-3150 large-scale dry-type transformers is made of imported high-quality cold-rolled silicon steel sheet, the third-order gold miter structure. The core pillars are F-level no-ceremony, and the core surface is epoxy-encapsulated which reduces the no-load loss, no-load current and iron. The core surface of fasteners and fasteners undergo special surface treatment, which further improves the appearance quality of the product.

Temperature control system and cold air system of SCB10-3150 large-scale dry-type transformers

Cross-flow top-blown cooling fan is adopted. The cooling fan of SCB10-3150 large-scale dry-type transformers have the characteristics of low noise, high wind pressure and beautiful appearance, which enhances the transformer's overload energy. Temperature control adopts intelligent temperature controller to improve the reliability of transformer operation.
