1. Scope of application

High Efficiency EnergySaving Dry Type Rectifier Transformer is a power transformer designed for rectification system. Its core task is to convert AC power into DC power, and provide stable power support for industrial DC power supply system by optimizing voltage matching and harmonic suppression. As the core component of the rectifier, it is widely used in electrolysis, electroplating, new energy hydrogen production, new energy storage, rail transit, communication base stations and other scenarios that require stable DC power supply. More than 90% of industrial DC power supplies need to be converted through rectifier transformers and rectifier equipment.

2. Product standards

    GB/T1094.1    GB/T1094.11   GB/T1094.12    GB/T10228   JB/T10088

    GB20052      GB/T7354      JB/T3837       GB/T4208    IEC60076-11  

3. Operation environment

1) Altitude: ≤1000 meters.

2) Ambient temperature: Maximum +40oC, Minimum -40oC.
3) Max outdoor wind speed: ≤45m/s.

4) Max Ground ramp degree: ≤3°.
5) Seismic level: ≤3m/s2 at horizontal direction and ≤1.5m/s2 at vertical direction.
6) Installation environment: No obvious and heavy pollution, no explosive and corrosive gas and dust, with good air ventilation and no severe vibration and shock.
7) If the application environment is different from the above standard conditions, please contact for customized designs.

4. Product advantages

1) The short-circuit current resistance is up to 150kA/2s, which can cope with frequent start-stop and high current shocks in scenarios such as electrolysis and electroplating.

2) Adopting 24-pulse or higher-order rectifier system, the harmonic suppression rate can reach more than 95%, significantly reducing power loss.

3) Support wide voltage regulation range (±10%), adapt to grid voltage fluctuations and complex load environments, some models integrate intelligent monitoring interfaces (such as 485 communication) to achieve remote operation and maintenance.

4) Focus on compact structure, low noise design, and urban grid harmonic control.

5) The winding has high mechanical strength, strong resistance to short circuit and current shock, and meets the durability requirements of industrial scenarios.

6) Multi-phase output configuration optimizes waveform smoothness to meet special needs such as electrolysis and high-frequency welding.
