Features
1. Innovative and advanced design strategy
Leveraging sophisticated computer software, the winding electric field is scrutinized under high voltage conditions to precisely calculate electric field gradients. This ensures the winding structure withstands high-voltage impulses. The insulation structure is thoroughly analyzed to guarantee safe operation, while meticulous calculations of magnetic leakage and temperature fields align field performance with design specifications. The lamination design is optimized to diminish magnetic distortion in gaps, thereby enhancing no-load performance.
2. Premium Iron Cores
Crafted from superior grain-oriented cold-rolled silicon-steel sheets, the iron core is precision-cut by specialized machinery to achieve minimal burr. The use of multi-step and 45° all-leaning joints effectively reduces no-load loss, no-load current, and noise. The core's clamping device, featuring a board structure, ensures high mechanical strength, while fastening nails provide adequate padding block pressure along the transformer's axis.
3. Pure Oxygen-Free Copper Windings for Reduced Load Loss
The inner coil is meticulously wound on the insulation barrel, with chamfered spacers and padding blocks to uniform the electric field and bolster stability. Employing BDK-80M synchronized lifting-up equipment during assembly guarantees precise axial placement of windings, strengthening axial robustness.
4. Superior Tank Design
Constructed with wide-width steel plates to minimize welding seams, the tank features a folded plate design, offering both elegance and formidable mechanical strength, successfully passing standard pressure and vacuum tests. Advanced welding technology and groove-type flanges ensure long-lasting, leak-free operation. The wide plate radiation system, equipped with robust, low-noise blowers, enhances heat dissipation efficiency, reduces the need for extra radiating plates, and prevents leaks. The innovative capsule-type conservator prolongs oil durability under vacuum, bolstering electric strength.
5. Comprehensive Protection System
Equipped with Pt100 thermal resistors for temperature control, a pressure relief valve with contacts on the tank's top, an oil level indicator with contact, vacuum relays on the conservator, and an oil pressure indicator with contacts in the tank, this system excels at signal conversion and transfer. Featuring pollution-retardant porcelain oil bushings for both HV and LV, it extends insulation space for high pollution environments. Stainless steel padding plates and terminal cases add a touch of elegance to the design.
