Transformer Dry Air Generator: Operation Procedure & Industrial Applications

Introduction to Dry Air Generators

Power & System Activation

1. Electrical Connection
   Link the power supply to the control panel terminals, verifying correct voltage compatibility.
2. Compressor Startup

• Switch the circuit breaker's air compression switch to "ON," ensuring the compression valve is fully open.

• The air compressor will initiate, building initial pressure.

3. Cooling System Activation
   Turn the cooling system switch to "ON" to maintain optimal operational temperature.

Dry Air Generation Setup

1. Automatic Drying Mode
   Set the air-drying heat reduction control switch to "AUTO." The system will automatically dehydrate incoming air via alternating "A" and "B"
2. drying chambers, completing a 5-minute regeneration cycle.
3. Operational Mode Selection

• Switch to "MAIN," then alternate between "A" (dehydration system) and "B" (circulation system) based on process requirements.

4. Pressure Regulation

• Monitor the exhaust pressure gauge after activating all systems.

• Close the exhaust valve gradually until pressure stabilizes at 0.5MPa.

Technical Considerations

• Dew Point Monitoring: Ensure generated air dew point meets equipment requirements (typically ≤ -40°C for transformer applications).

• Seal Integrity: Regularly inspect flanges and connections to prevent dry air leakage.

• Shutdown Protocol: Depressurize the system in reverse operational order to avoid equipment damage.
