Live water flushing has emerged as a pivotal technological advancement in power transformer cooling, effectively addressing the long-standing challenge of inefficient heat dissipation—especially for outdoor transformers in summer. CHH Power has adopted this innovative method to enhance cooling performance, ensuring safe and stable operation of power transformers during peak load periods.
1. Background: Traditional Cooling Pain Points
Power transformer cooling has long been a key challenge for manufacturers. In summer, transformers face high heat generation and slow heat dissipation, leading to excessive temperature rise. Traditional cooling methods offer limited and delayed cooling effects, failing to meet the demands of safe operation during extreme conditions. This gap prompted the development of live water flushing technology—a game-changer in transformer thermal management.
2. Applicable Scenarios & Core Problems Solved
CHH Power’s live water flushing is specifically designed for forced oil circulation air-cooled power transformers—the primary main transformers in outdoor substations.
Core Problem Addressed
Long-term outdoor operation causes heavy dirt accumulation in radiator gaps. This dirt severely blocks airflow, reducing fan cooling efficiency and leading to a significant rise in transformer oil temperature. High oil temperature poses major hidden dangers to the transformer’s safe and stable operation, especially during summer peak loads.
3. Implementation Requirements & Standard Process
To ensure safe and effective live water flushing, CHH Power strictly follows a standardized workflow and safety protocols:
(1) Pre-Implementation Preparation
- Formulate a comprehensive live water flushing operation plan, detailing flushing sequence, water pressure parameters, and emergency response measures.
- Establish strict on-site safety measures: isolate the operation area, deploy insulation protection, and assign dedicated safety supervisors.
- Inspect flushing equipment in advance (e.g., high-pressure water pumps, insulated nozzles) to ensure no leaks, stable pressure, and compliance with electrical safety standards.
(2) On-Site Flushing Execution
- Conduct flushing with the transformer energized (eliminating the need for power outage, ensuring continuous power supply).
- Target radiator gaps with controlled high-pressure water to remove dirt without damaging the radiator or insulation components.
(3) Post-Flushing Verification
- Confirm radiator cleanliness and unobstructed airflow.
- Monitor transformer oil temperature for 24–48 hours to verify cooling efficiency improvement.
4. Core Advantages of Live Water Flushing Technology
- Rapid Temperature Reduction: Directly removes heat-blocking dirt, quickly alleviating transformer overheating issues.
- Enhanced Heat Dissipation Efficiency: Restores radiator performance, ensuring fans operate at optimal cooling capacity.
- Reduced Failure Risk: Post-flushing, the transformer’s failure probability is significantly lowered, improving operational reliability.
- Peak Load Guarantee: Effectively supports the transformer to cope with summer peak power demand, avoiding overload shutdowns.
- No Power Outage Required: Live operation ensures uninterrupted power supply to users, minimizing economic losses from downtime.
5. Technological Progress & Future Outlook
Live water flushing represents a major leap in power transformer cooling technology, providing critical technical support and innovative momentum for transformer applications. CHH Power is committed to continuous technological optimization:
- Improve flushing equipment precision to adapt to different transformer models.
- Optimize water pressure and flow control to enhance dirt removal efficiency while protecting transformer components.
- Integrate intelligent monitoring to automatically detect radiator dirt accumulation and trigger timed flushing.
This ongoing innovation will further maximize the technology’s advantages, enabling transformers to deliver more reliable performance in diverse operating environments.
