S11 series oil immersed power transformer core adopts high-quality high-magnetic-oriented grain-oriented silicon steel sheet, plane laminated core structure, step-type multi-level joint, low no-load loss and low noise. The box body adopts a corrugated oil tank full sealing structure. The finished product is vacuum-filled. This series of products has the characteristics of beautiful appearance, excellent performance, maintenance-free, reasonable structure, advanced technology, stable and reliable product performance, and is a new generation of energy-saving and environment-friendly products.
1. The core is made of high-quality cold-rolled oriented silicon steel sheet, which is manufactured by the automatic cross-cutting process and the latest step-lap joint process. It improves the distribution of magnetic flux density inside the core and reduces the vibration energy of the core. Ground reduces noise and reduces losses.
2. The coil is made of high-strength enameled wire (or paper-wrapped wire), cylindrical (or cake-type) structure, uniform distribution of ampoule, reasonable insulation structure and strong resistance to short circuit.
3. The transformer body is fastened with anti-loose structure, the fastening part has self-locking locknut, and the non-suspended core structure is adopted, which can ensure the looseness after running for long-distance transportation.
4. The corrugated sheet of the corrugated oil tank replaces the oil conservator. The corrugated sheet can be shrunk with the change of the volume of the transformer oil, so that the transformer is isolated from the atmosphere, preventing and slowing the deterioration of the oil and the moisture of the insulation, enhancing the operational reliability, and avoiding normal operation. maintain.
5. Equipped with "telemetry" signal thermometer and pressure reliefvalve to enhance the reliability of transformer operation
