Comparative Analysis of Standard Frameworks
Compared with GB7251.6-2015, this standard is mainly optimized in the following aspects:
- New Content:Special requirements for wind power generation environment, such as vibration resistance, corrosion resistance, etc.
- Detailed requirements: More stringent indicators are proposed for the insulation materials and protection level of the bus duct.
Implementation suggestions
To ensure the safe and stable operation of the wind power bus duct system, the following measures are recommended:
- Strictly follow the installation instructions for operation, especially in high altitude and low temperature environments.
- Regularly check the effectiveness of the protection circuit to ensure that the grounding resistance is ≤0.1Ω.
- Under special environmental conditions (such as areas with salt spray or dust), it is recommended to use a bus duct system with a higher protection level.
