Model of amorphous alloy transformer

　　Amorphous alloy transformers are renowned for their high efficiency and energy-saving advantages. Common models are classified based on structure, function, and series, with key parameters and selection recommendations provided as follows:

　　I. Models Classified by Structure/Function

　　E-Type Amorphous Alloy Transformer

　　Features: Designed for low-frequency applications, with low core losses and high efficiency, suitable for power systems.

　　Typical Applications: Used in power distribution within modern power grids to replace traditional high-loss transformers.

　　T-Type Amorphous Alloy Transformer

　　Features: Supports multiple input/output channels, exhibits high saturation induction intensity and low magnetic permeability, adapting to complex voltage/current conditions.

　　Typical Applications: Employed in industrial automation, renewable energy integration, and other scenarios requiring multi-voltage matching.

　　RF-Type Amorphous Alloy Transformer

　　Features: Optimized for high-frequency applications, featuring high saturation magnetic flux density and low hysteresis loss.

　　Typical Applications: Utilized in RF circuits, communication equipment, and other high-frequency electronic domains.

　　II. Models Classified by Series

　　SCBH Series (Dry-Type Transformers)

　　Sub-Series: SCBH15, SCBH17, SCBH19, etc.

　　Features: Primarily epoxy-resin cast, offering fire resistance, explosion prevention, and maintenance-free operation, ideal for indoor, densely populated settings.

　　Capacity Range: 30 kVA to 3,150 kVA, with voltage ratings of 10 kV/35 kV.

　　Energy Efficiency: Reduces no-load losses by 75% and load losses by 15% compared to GB standards.

　　Typical Models:

　　SCBH15-1250/10: 1,250 kVA, 10 kV class, suitable for large commercial complexes.

　　SCBH19-1000/10: 1,000 kVA, Class 1 energy efficiency, meeting high-density load demands.

　　SGBH Series (Dry-Type Transformers)

　　Features: Similar to the SCBH series, but specific models vary by manufacturer, all offering energy-saving capabilities.

　　Typical Applications: Overlap with SCBH series; selection requires reference to manufacturer-specific technical parameters.

　　SH15 Series (Oil-Immersed Transformers)

　　Features: Oil-immersed natural cooling, suitable for outdoor use or settings with lower fire safety requirements.

　　Capacity Range: 30 kVA to 2,500 kVA, with voltage ratings of 10 kV/20 kV.

　　Energy Efficiency: Reduces no-load losses by 80% compared to S9 series, significantly improving operational economy.

　　Typical Models:

　　SH15-500/10: 500 kVA, 10 kV class, ideal for rural power grid upgrades.

　　SH15-1600/20: 1,600 kVA, 20 kV class, meeting medium-voltage, long-distance transmission needs.

　　III. Models for Special Applications

　　SRN-MD Series (Underground Transformers)

　　Features: Fully sealed, high fire-point oil, high-temperature resistance (F-class insulation), with an IP68 enclosure rating, capable of submerged operation.

　　Typical Applications: Used in underground substations and flood-prone areas, such as the SRN-MD 500/10 produced by Jiangsu Zhongdian Group.

　　ZCGSH15 Series (Pad-Mounted Transformers)

　　Features: Integrated co-box structure, combining high-voltage switches and low-voltage distribution for space savings.

　　Typical Applications: Deployed in urban compact substations and temporary power supply projects.

　　IV. Key Selection Parameters and Recommendations

　　Voltage Rating: Choose from 10 kV, 20 kV, or 35 kV based on grid requirements.

　　Capacity Matching:

　　Commercial Buildings: Estimate based on load density (e.g., 1,000 kVA for 10,000 m² office buildings).

　　Industrial Users: Reserve a 20% margin based on total equipment power.

　　Energy Efficiency Rating: Prioritize Class 1 energy efficiency models (e.g., SCBH19 series) for lower long-term operational costs.

　　Environmental Adaptability:

　　Humid/Corrosive Environments: Select dry-type transformers (SCBH/SGBH series) with enhanced protective coatings.

　　Outdoor/High-Altitude Areas: Opt for oil-immersed transformers (SH15 series) with adjusted insulation ratings.

　　Manufacturer Variations: Note that model naming conventions may differ slightly among manufacturers (e.g., "H" indicating amorphous alloy); verify against specific parameter tables.
