Dry Type Transformer Maintenance Checklist: Key Tips

The maintenance of dry type transformers is crucial for ensuring their longevity and optimal performance. This checklist provides key tips for maintaining these transformers, with a focus on the products offered by Zhejiang Shuntong Electric Co., Ltd.

Oil Type Transformer Maintenance Checklist

While the focus is on dry type transformers, it’s important to understand the maintenance of oil type transformers for comparison. Key points include:

• Inspection of Oil Levels: Ensuring the oil level is within the recommended range.

• Testing Oil Quality: Regular testing for contamination and degradation.

• Checking for Leaks: Inspecting the transformer for any oil leaks.

Dry-Type Transformer Maintenance Cycle

Dry type transformers have a different maintenance cycle compared to oil-filled transformers. The cycle typically includes:

• Visual Inspections: Regular visual checks for any physical damage, corrosion, or loose connections.

• Thermal Imaging: Using thermal imaging to detect hotspots that could indicate potential issues.

• Electrical Testing: Periodic testing of winding resistance, insulation resistance, and impedance.

Tips for Preventive Maintenance

Preventive maintenance is essential for avoiding unexpected downtime and extending the life of dry type transformers. Here are some key tips:

• Regular Cleaning: Cleaning the transformer to remove dust and debris can prevent overheating.

• Monitoring Load Conditions: Keeping an eye on load fluctuations can help prevent overloading.

• Climate Control: Ensuring the environment around the transformer is within the specified temperature and humidity range.

Dry Type Transformer Installation Checklist

Proper installation is the first step in maintenance. The installation checklist should include:

• Site Preparation: Ensuring the installation site meets the manufacturer’s requirements.

• Correct Alignment: Verifying that the transformer is correctly aligned and leveled.

• Electrical Connections: Checking all electrical connections for tightness and proper grounding.

• Professional Assistance: Consulting with professionals for complex maintenance tasks or when issues arise.
