Product Introduction
The CEEG 24-pulse cast resin dry-type rectifier transformer stands as a beacon of innovation for locomotive traction substations, EMU (Electric Multiple Unit) traction substations, urban rail transit systems, and electrified highway systems. This advanced transformer offers unparalleled safety, reliability, environmental friendliness, and energy efficiency, all while boasting an extended service life compared to conventional oil-immersed transformers. The product architecture includes two robust 12-pulse axial split traction rectifier transformers.
Product Features
Harmonic Filtering: Employing 24-pulse rectification, this transformer minimizes harmonics; its balanced key technical parameters effectively reduce non-characteristic harmonics, enhancing overall system performance.
Advanced Temperature Control: Equipped with an embedded PT thermistor, it facilitates precise temperature detection and control. The system includes an over-temperature alarm, trip functions, audio-visual alerts, fan start, fan overload protection, and a computer interface for seamless monitoring.
Low Loss and Low Noise: Featuring a 45°C full-stepped joint iron core with a specialized resin coating, this design significantly reduces no-load loss, no-load current, and operational noise, ensuring a quieter, more efficient transformer.
High Insulation: Constructed with F-class insulation materials, the transformer maintains partial discharge levels well below 5pC, ensuring superior insulation performance.
Moisture and Rust Resistance: Designed with longitudinal airway foil structure low-voltage coils and an epoxy resin coating, this transformer offers exceptional resistance to moisture and rust, prolonging its operational lifespan.
Customizable: With a flexible design, the transformer can be tailored swiftly to meet specific requirements, ensuring a quick response to customer needs.
