Hydrogen Dry-Type Rectifier Transformer Product Introduction

1. Product Introduction

The hydrogen dry-type rectifier transformer is a professional power conversion equipment independently developed and optimized for industrial hydrogen production electrolysis systems. Different from traditional oil-immersed rectifier transformers, this product adopts epoxy resin cast dry-type structure, completely eliminating insulating oil filling, which fundamentally avoids oil leakage, fire and explosion risks in hydrogen production environments with high safety requirements.

Tailored for the working characteristics of alkaline water electrolysis and PEM hydrogen production equipment, the transformer realizes precise voltage regulation and phase-shift rectification, converting industrial high-voltage alternating current into stable direct current suitable for electrolytic hydrogen production. It matches the high-load, continuous and stable operation demands of hydrogen production projects. With mature dry-type insulation technology and optimized winding structure design, the equipment can maintain long-term stable operation in closed, humid and high-cleanliness hydrogen production workshops, serving as the core power supporting equipment for green hydrogen and industrial hydrogen production lines.

2. Core Product Technical Parameters

The product supports customized design for multiple specifications to adapt to hydrogen production projects of different scales. The mainstream conventional technical parameters are listed below, and all indicators comply with international industrial power standards and hydrogen production industry safety specifications.

3. Product Core Features

3.1 Ultra-high Safety for Hydrogen Production Scenarios

Adopts full dry-type oil-free design with no flammable insulating oil inside, completely eliminating fire, explosion and oil leakage risks in hydrogen-rich working environments. The H-class high-temperature resistant insulating material and integral cast winding structure can effectively resist insulation aging, avoid breakdown and short-circuit faults, and meet the strict safety production standards of hydrogen production plants. The sealed structure also prevents internal spark leakage, ensuring zero safety hazards in flammable and explosive hydrogen production workshops.

3.2 Stable and Efficient Power Conversion Performance

Optimized multi-winding phase-shift rectification structure with precise phase shift control effectively reduces harmonic interference, outputs stable DC power, and perfectly matches the continuous power supply demand of electrolytic hydrogen production equipment. The whole machine adopts high-quality silicon steel sheets and copper windings, with extremely low no-load loss and load loss, and the full-load efficiency is up to 98.5% or above, which effectively reduces the energy consumption cost of long-term hydrogen production operation. The low partial discharge design ensures that the equipment will not have insulation attenuation during long-term continuous operation.

3.5 Strong Environmental Adaptability

The product can adapt to harsh industrial environments such as high humidity, dust and large temperature difference in hydrogen production workshops. It can operate stably in the environment with relative humidity ≤90% (20℃) without additional moisture-proof protection. The standard model is suitable for altitudes below 1000 meters, and high-altitude customized models can meet the operation requirements of altitudes up to 2000 meters. The overall structure is compact, with strong vibration resistance and anti-interference ability, and will not be affected by the operation vibration of surrounding hydrogen production equipment.

3.4 Low Maintenance and Long Service Life

Compared with oil-immersed transformers that require regular oil testing and replacement, this dry-type product has no consumable oil products. The integral cast winding has good anti-aging and anti-corrosion properties, with a designed service life of more than 30 years under normal operating conditions. The equipment runs with low noise and low failure rate, avoiding frequent shutdown maintenance and effectively improving the continuous operation rate of the hydrogen production line.

5. Product Maintenance and After-sales Service

5.1 Daily Maintenance Guidelines

This product is designed with low maintenance characteristics, and routine daily inspection and maintenance can ensure long-term stable operation without complex professional operation. First, regularly clean the dust and sundries on the surface of the winding and casing to avoid dust accumulation affecting heat dissipation, especially for forced air cooling models, ensure the air inlet and outlet of the cooling fan are unobstructed. Second, regularly check the operating status of cooling fans, temperature control and temperature measuring devices to ensure the normal operation of heat dissipation and temperature monitoring systems.

In addition, it is necessary to regularly observe the insulation surface for cracks, discoloration and aging phenomena, and use professional instruments to measure the insulation resistance value. If abnormal data is found, stop operation for inspection in time. It is recommended to conduct a comprehensive professional inspection every six months and a full performance test every year to eliminate potential faults in advance.

5.2 Fault Handling Instructions

In case of abnormal noise, excessive temperature rise, alarm trip and other faults during operation, the equipment shall be shut down immediately for inspection, and it is forbidden to operate with faults. For simple faults such as fan damage and line looseness, on-site maintenance personnel can replace and fix them according to the operation manual; for complex faults such as insulation abnormality and internal component failure, do not disassemble privately, and contact the after-sales technical team in time for professional processing.
