An amorphous alloy power transformer is a highly efficient and energy-saving transformer that utilizes amorphous alloy strip as its core material.
In-Depth Analysis of Amorphous Alloy Power Transformers
1. Product Overview
An amorphous alloy power transformer is a highly efficient and energy-saving transformer that utilizes amorphous alloy strip as its core material. Its core advantage lies in significantly reducing no-load and load losses through the unique physical properties of amorphous alloy materials, such as high magnetic permeability and low coercivity, thereby enhancing operational efficiency. This type of transformer is widely used in power grids, industrial, commercial, and other fields, making it an ideal replacement for traditional silicon steel transformers and aligning with China's "dual carbon" strategic goals.
2. Technical Characteristics and Performance Advantages
| Technical Characteristic | Detailed Description |
|---|---|
| High Efficiency and Energy Saving | No-load losses are reduced by 60%-80% compared to traditional silicon steel transformers, while load losses are reduced by 10%-15%. |
| Material Properties | Amorphous alloy strips (e.g., Fe-Si-B series) feature an atomically disordered structure, resulting in extremely low energy losses during magnetization. |
| Environmental Performance | The manufacturing process consumes less energy, reducing full lifecycle carbon emissions by approximately 50% and complying with RoHS environmental standards. |
| Operational Stability | Low magnetostriction coefficient leads to a noise level 5-10 dB lower than that of traditional transformers. |
| Short-Circuit Resistance | Compact core structure enhances short-circuit withstand capability by over 20%. |
3. Core Performance Parameters
| Parameter Category | Typical Value/Range | Description |
|---|---|---|
| Rated Capacity | 30KVA-5000KVA | Covers small to large distribution needs (e.g., SH15-630KVA, SH15-2500KVA models). |
| Voltage Class | High-voltage side: 10kV/35kV; Low-voltage side: 0.4kV | Standard power system configuration, with customizable voltage combinations supported. |
| Energy Efficiency Grade | National Grade 1 | Complies with GB 20052-2020 standards, with no-load loss limits significantly lower than those of traditional transformers. |
| Connection Group | Dyn11/Yyn0 | Ensures voltage stability and operational reliability. |
| Short-Circuit Impedance | 4%-6.5% | Enhances short-circuit withstand capability and ensures equipment safety. |
| Noise Level | <50dB (10 dB lower than national standards) | Optimized core and coil structures reduce noise pollution. |
| Cooling Method | Oil-immersed self-cooling/Dry-type self-cooling | Suitable for various environmental requirements. |
