Introduction
1. Standard Overview
GB/T 22072-2018 "Technical Parameters and Requirements for Dry-type Amorphous Alloy Core Distribution Transformers" is a national standard of the People's Republic of China, which specifies the terms and definitions, performance parameters, technical requirements, etc. of dry-type amorphous alloy core distribution transformers. This standard is applicable to indoor three-phase dry-type amorphous alloy core non-excitation voltage-regulating distribution transformers with system nominal voltages of 6kV, 10kV, 20kV and 35kV.
2. Comparison of standard frameworks
| Standard version | Applicable voltage level (kV) | Main technical changes | Description of modified content |
|---|---|---|---|
| GB/T 22072—2018 | 6, 10, 20, 35 | Added performance parameters and sound level levels of 20kV and 35kV products | Adjusted normative references, no-load current and sound level |
| GB/T 22072—2008 | 6, 10 | - | Technical requirements for 20kV and 35kV products are not included |
3. Implementation Suggestions
When selecting amorphous alloy core transformers, focus on the following factors:
- Select a transformer with appropriate capacity according to load requirements
- Ensure that the transformer meets the requirements of GB/T 1094.11 and GB/T 1094.12
- In high temperature or high humidity environments, pay attention to the measurement and protection of insulation resistance values
4. Analysis of Technological Evolution
From GB/T 22072-2008 to GB/T 22072-2018, the main technical improvements include:
- Added support for higher voltage levels (20kV and 35kV)
- Optimized control of no-load current and sound level
- Improved accuracy of load loss calculation
