Product Introduction
The cutting-edge CEEG 24-pulse cast resin dry-type rectifier transformer stands as a beacon of innovation in the realm of locomotive traction substations, EMU (Electric Multiple Unit) traction substations, urban rail transit systems, and electrified highway systems. It offers unparalleled safety, reliability, eco-friendliness, energy efficiency, and longevity compared to traditional oil-immersed transformers. This groundbreaking product features two 12-pulse axial split traction rectifier transformers, setting a new standard in transformer technology.
Product Features
Harmonic Filtering: Leveraging advanced 24-pulse rectification technology, it dramatically reduces harmonics and balances essential technical parameters, significantly minimizing non-characteristic harmonics for optimal performance.
Advanced Temperature Control: Equipped with an embedded PT thermistor, it offers precise transformer temperature detection and control. It includes an over-temperature alarm and trip functionality, audio-visual alerts, fan start and overload protection, as well as a computer interface for seamless integration.
Low Loss and Low Noise: Featuring a 45°C full-stepped joint iron core with a specialized resin coating on the surface, this transformer significantly reduces no-load loss, no-load current, and operational noise, ensuring a quieter, more efficient performance.
High Insulation: Constructed with F-class insulation materials, it maintains partial discharge levels below 5pC, ensuring superior insulation and reliability.
Moisture and Rust Resistance: The longitudinal airway foil structure of the low-voltage coils, combined with an epoxy resin coating, provides exceptional resistance to moisture and rust, enhancing the transformer's durability.
Customizable: Designed with flexibility in mind, it can be quickly adapted to meet specific requirements, ensuring a tailored solution for every application.
