Introduction
GB/T 35710—2017 Standard Overview
The National Standard of the People's Republic of China GB/T 35710—2017 "Guidelines for Capacity Assessment of Power Transformers of Voltage Levels 35kV and Below" was issued in 2017, which mainly provides detailed guidance specifications for capacity assessment of power transformers of voltage levels 35kV and below.
Standard Framework Comparison
| Dimensions | Contents | Interpretation |
|---|---|---|
| Testing Conditions | Testing Environment, Instrument Accuracy, Current and Voltage Transformer Requirements | Ensure data accuracy and avoid external interference affecting test results. |
| Evaluation process | Preset capacity assumptions, load loss calculation, short-circuit impedance correction | Through step-by-step verification, determine whether the actual capacity of the transformer meets the standard. |
| Implementation suggestions | Temperature rise test, capacity reduction treatment, actual application case analysis | Optimize the transformer capacity evaluation plan based on site conditions and operating environment. |
Interpretation of core clauses
Testing requirements (4.1-4.2)
GB/T 35710 specifies the necessary test conditions and items for power transformer capacity evaluation, including DC resistance, load loss, no-load loss and temperature rise test. These test items require the use of high-precision instruments and ensure that the test environment meets the standard requirements.
Evaluation method (5.2)
The standard details the specific steps of transformer winding DC resistance measurement, preset capacity assumptions, load loss calculation and short-circuit impedance correction. Through step-by-step verification, the accuracy and reliability of the evaluation results are ensured.
Implementation suggestions
In actual applications, the capacity assessment of power transformers needs to be combined with site conditions and operating environment, and the following implementation suggestions should be taken:
- For oil-immersed transformers, focus should be placed on whether the temperature rise test results meet the requirements of GB/T1094.2.
- For dry-type transformers, temperature rise tests should be carried out at the preset capacity, and the capacity level should be adjusted as needed.
- During the evaluation process, if the short-circuit impedance deviation is found to exceed ±10%, the capacity should be re-assumed and verified in a timely manner.
