The choice between a dry-type transformer and an oil-immersed transformer primarily depends on specific application requirements and environmental conditions. Below are the typical application scenarios for both types:
High-Rise Buildings and Commercial Centers: Dry-type transformers, due to their fire-resistant and explosion-proof features, are ideal for installation in high-occupancy areas such as high-rises, shopping malls, and office buildings.
Hospitals and Schools: In environments demanding high safety and reliability, dry-type transformers ensure stable power supply while offering ease of maintenance.
Industrial Production Lines: Dry-type transformers are well-suited for industrial environments requiring high reliability and low maintenance, such as automated production lines and precision machine tools.
Data Centers and Communication Base Stations: Owing to their high efficiency, low noise, and absence of oil contamination, dry-type transformers are optimally suited for power supply systems in data centers and communication base stations.
Underground & Tunnel Applications: Dry-type transformers’ oil-free cooling design makes them a safer choice for fire-risk-sensitive environments like subways and utility tunnels.
Heavy Industrial & Power Grid Applications: Oil-immersed transformers excel in high-capacity, high-load scenarios like factories, substations, and transmission networks.
Outdoor and Harsh Environments: Owing to their superior heat dissipation capabilities, oil-immersed transformers are ideally suited for installation in outdoor or demanding conditions, such as pole-mounted setups and open-air locations.
High-Humidity and High-Temperature Environments: Oil-immersed transformers are capable of stable operation in high-humidity and high-temperature conditions, making them well-suited for industries such as petroleum and chemical processing.
Budget-Driven Scenarios: Oil-immersed transformers’ lower upfront costs make them a preferred choice for cost-conscious projects.
Dry-type transformers: Utilize air or solid insulating materials (e.g., epoxy resin) and do not require insulating oil, thus eliminating the need for regular replacement or disposal of insulating oil. Maintenance primarily focuses on periodic cleaning and inspection of the condition of the insulating materials.
Oil-immersed transformers: Use insulating oil as both an insulating and cooling medium, requiring regular inspection and maintenance of the oil's quality, including its electrical properties, moisture content, and impurity levels. Oil filtration or replacement must be performed when necessary.
Dry-type transformers: Typically employ natural air cooling or forced air cooling. Maintenance primarily focuses on ensuring the proper operation of ventilation equipment and regularly cleaning heat sinks and ventilation ducts.
Oil-immersed transformers: Rely on oil circulation and external cooling systems (e.g., radiators) for heat dissipation. Maintenance involves inspecting the condition of cooling systems, ensuring their proper functionality, and preventing transformer overheating.
Dry-type transformers: Require periodic inspections of windings, core, and insulation materials to prevent dust accumulation and insulation degradation. Additionally, verify proper tightness of fasteners and electrical connections to ensure operational safety.
Oil-immersed transformers: Require regular monitoring of oil level, oil temperature, and variations in voltage and current levels. Additionally, the condition of silica gel in the breather must be inspected, with moisture-saturated silica gel promptly replaced.
Dry-type transformers: In the event of failures such as winding or insulation material damage, full unit replacement may be required. Maintenance tasks are relatively straightforward, but fault resolution often demands specialized technical expertise.
Oil-immersed transformers: Fault resolution may involve oil replacement and transformer drying processes. Maintenance tasks are comparatively complex but can extend equipment lifespan through targeted component replacement.
Dry-type transformers: Suitable for indoor use and environments requiring high standards of fire and explosion prevention, with maintenance tasks primarily focused on ensuring cleanliness and dryness of the equipment.
Oil-immersed transformers: Suitable for outdoor deployment and harsh environments, with maintenance requiring measures such as waterproofing, dust resistance, and anti-corrosion treatments.
