Features
1. Scientific and Advanced Design Scheme
Harnessing cutting-edge computer software, the transformer's winding electric field is meticulously analyzed under high voltage to precisely map the field gradient distribution. This ensures the winding structure withstands high voltage impulses safely. Comprehensive analysis of the insulation and magnetic structures guarantees impeccable operational safety and performance. The lamination design is expertly optimized to minimize distortion and elevate no-load efficiency, setting a new benchmark in engineering excellence.
2. Iron Cores
The heart of this transformer lies in its high-grade, grain-oriented cold-rolled silicon-steel sheets, precision-cut with specialized shearing machinery to ensure minimal burr. These iron cores, featuring innovative multi-step and 45° all-leaning joints, significantly reduce no-load losses, current, and noise. The robust board structure clamping device imparts exceptional mechanical strength, while secure fastening nails maintain optimal axial padding block pressure for unrivaled performance.
3. High Purity Oxygen-Free Copper Windings
Meticulously wound on insulation barrels, the inner coils are fortified with chamfering spacers and padding blocks to harmonize the electric field, bolstering stability. The use of BDK-80M synchronized lifting-up equipment during assembly ensures precise axial positioning and strengthens the windings' axial integrity, reducing load loss effectively.
4. Tank
Crafted from wide-width steel plates, the tank boasts fewer welding seams on its flat roof for a sleek, compact design with superior mechanical strength, passing stringent positive pressure and vacuum evaluations. Employing state-of-the-art welding techniques and groove-type flanges, the construction guarantees long-lasting, leak-free performance. The equipped wide plate radiation system with heavy-duty, low-noise blowers enhances heat dissipation efficiency, cutting down on radiating plates while preventing leaks. The integrated capsule-type conservator optimally delays oil aging under vacuum conditions, reinforcing electrical strength.
5. Protection System
For advanced safety and operational efficiency, the transformer incorporates a Pt100 thermal resistor temperature control system. Atop the tank sits a pressure relief valve with contacts, complemented by an oil indicator with contact and vacuum relays in the conservator. Inside the tank, an oil pressure indicator with contacts provides further reliability. Both HV and LV bushings are pollution-resistant, porcelain oil types designed for high-pollution environments. The transformer's aesthetic and durability are enhanced by stainless steel padding plates and terminal cases, ensuring an elegant and robust appearance.
