Rectifier Transformer Product Introduction
The Rectifier Transformer is a high-performance device specifically designed for high-load power conversion scenarios, widely used in rail transportation, industrial manufacturing, and other fields. With its excellent energy-saving performance, anti-short circuit capability, and fully sealed protective design, it can ensure stable operation even in extreme environments, helping customers achieve efficient, reliable, and safe power supply needs for their power systems. It supports customized capacity ranges (30kVA-3200kVA) to meet diverse engineering requirements.
Product features
The core function of the rectifier transformer: to provide accurate voltage matching for the rectifier device, and to offer efficient and stable power conversion support for high-energy-consuming industrial scenarios.
Development objectives: focus on suppressing waveform distortion generated during the rectification process, thereby reducing harmonic pollution to
Core : The rectifier transformer uses 30Q130 high magnetic conductivity silicon steel sheets and adopts an advanced 3～6 level step-lap core stacking multi-level lamination method, significantly reducing no-load losses, no-load current, and noise.
Windings : The electromagnetic wire of the transformer uses highly conductive oxygen-free copper wire. The windings adopt new overall assembly processes such as cylindrical, double pancake, and novel helical structures, making the product structure more compact and ensuring effective main insulation. Strengthening of the first and last layers improves insulation performance. The outer surface of the windings is wrapped with high-strength tightening straps, enhancing the mechanical strength of the windings and greatly improving the product's impact resistance and short-circuit resistance.
Body : Insulating spacers in the body are all made of high-strength laminated wood and laminated cardboard for support, achieving over 95% support area at the ends of the windings, further enhancing the product's short-circuit resistance and operational reliability. The connection between the body and the tank cover adopts a flat plate with a buffer structure, overcoming issues of "suspension" and "lid pressing." Insulation materials are all wound with high-strength, high-density cable paper, with an allowable pressure of 45Mpa.
Tank : The tank uses heat-dissipating oil pipes (double and triple-row oil pipes use plug-in methods), or stepped sheet-type coolers. It can also be calculated and installed with sheet-type coolers according to user requirements, or corrugated tanks, forced oil air cooling, or forced oil water cooling coolers may be used. Surface treatment of the tank: The transformer shell paint uses "three-proof paint" (salt fog-proof, damp heat-proof, mold-proof). This paint has strong adhesion with the primer, good decorative properties, excellent film oil resistance, corrosion resistance, gloss retention, color retention, good leveling, and excellent covering power.
