630KVA dry-type transformer

　　The 630KVA dry-type transformer is a widely used power equipment in both industrial and commercial sectors. Below is an introduction covering its technical parameters, performance advantages, application scenarios, pricing, and selection recommendations:

　　I. Technical Parameters

　　Rated Capacity: 630KVA, suitable for medium-scale power demand scenarios.

　　Voltage Levels: Common voltage configurations include 10kV/0.4kV, meeting the power distribution needs of most industrial and commercial applications.

　　Cooling Method: Typically employs air natural cooling (AN) or air natural cooling with fan assistance (AF) to maintain an appropriate operating temperature under normal conditions.

　　Insulation Class: Generally utilizes H-class or F-class insulation materials, offering high heat resistance and mechanical strength.

　　Voltage Regulation: The high-voltage side is usually equipped with taps, with a voltage regulation range of ±2×2.5% or ±5%, allowing voltage adjustment based on actual load requirements.

　　II. Performance Advantages

　　Safety and Reliability: Dry-type transformers do not use oil as an insulating medium, eliminating potential safety hazards such as oil leakage and fire risks associated with oil-immersed transformers, thus ensuring safer and more reliable operation.

　　Environmental Friendliness and Energy Efficiency: By adopting high-quality insulation materials and advanced manufacturing processes, they reduce no-load and load losses, improving energy utilization efficiency and meeting energy conservation and emission reduction requirements.

　　Easy Maintenance: With a simple structure, they are relatively easy to maintain and service, eliminating the need for regular replacement of insulating oil and reducing long-term operating costs.

　　Strong Adaptability: Capable of operating under harsh environmental conditions, such as humid, dusty, or high-temperature environments, demonstrating high environmental adaptability.

　　III. Application Scenarios

　　Industrial Sector: Suitable for power distribution systems in manufacturing plants, chemical factories, mines, and other industrial enterprises, providing stable power supply to various production equipment.

　　Commercial Buildings: Can be used for power distribution in large shopping malls, office buildings, hotels, and other commercial facilities, meeting the power demands of lighting, air conditioning, elevators, and other equipment.

　　Public Facilities: In schools, hospitals, transportation hubs, and other public facilities, 630KVA dry-type transformers can provide safe and reliable power guarantees to ensure the normal operation of these facilities.

　　IV. Pricing

　　The price of a 630KVA dry-type transformer is influenced by various factors, such as brand, materials, and configuration. Generally, dry-type transformers are more expensive than oil-immersed transformers. Taking the SCB10-630KVA dry-type transformer as an example, its price is approximately around 56,000 yuan per unit, but prices may vary among different manufacturers and configurations.

　　V. Selection Recommendations

　　Determine Load Requirements: Select a transformer with an appropriate rated capacity based on the size and nature of the actual electrical load to avoid overloading or excess capacity.

　　Consider Environmental Conditions: Choose products with corresponding protection classes and adaptability based on the environmental conditions of the transformer installation site, such as temperature, humidity, and altitude.

　　Focus on Product Quality and After-Sales Service: Select manufacturers with good reputation and production strength to ensure reliable product quality. Pay attention to the manufacturer's after-sales service capabilities to ensure timely technical support and maintenance services during use.
