Water Removal Transformer Oil Filtration Machine with Roots Pump

Introduction：

Technical parameters：

Advantages：

1. Deep Purification Treatment of Transformer Insulating Oil: Simultaneously removes moisture, air, acetylene fault gases, and solid mechanical impurities from the oil. New oil undergoes pretreatment before storage, regenerates deteriorated oil from overhauls, and periodically filters operating oil online. The treated oil directly meets the insulation requirements for equipment commissioning.

   
   

2. Vacuum Injection Operation for Large Electrical Equipment: A separate dual-stage vacuum system allows for vacuum drying and vacuum oil injection into transformers, instrument transformers, and capacitor tanks ≤50m³. This dual-purpose machine eliminates the need for a separate vacuum unit.

   
   

3. Hot Oil Circulation Drying and Maintenance: An adjustable heating system (30~70℃) circulates hot oil to dehumidify damp transformer bodies, rapidly restoring insulation performance and shortening the drying period after overhauls.

   
   

4. Two-Way Oil Transfer and Circulation: Interchangeable oil circuits allow a single unit to perform self-circulation for a single transformer, cross-tank oil transfer for multiple transformers, and centralized purification of batches of oil from the oil depot.

   
   

5. Supporting intelligent functions:

• ① Constant temperature automatic heating, temperature range freely set from 30 to 70 degrees Celsius, automatic start/stop heating with a temperature difference of 4 degrees Celsius;

• ② Variable frequency oil pump with stepless speed regulation and automatic vacuum level balancing;

• ③ Independent audible and visual alarms for multiple faults, one-button reset for faults;

• ④ Dedicated sampling valve for collecting oil samples for testing during operation;

• ⑤ Centralized drain valve for the entire unit, allowing for regular draining without disassembling pipelines.

Suitable Application Scenarios

1. Provincial/Municipal Large Substation Operation and Maintenance:Overhaul of 220kV and 500kV ultra-high voltage main transformers, hot oil drying and deep purification of insulating oil; centralized batch oil filtration for multi-bay transformers; trailer-mounted mobility eliminates the need for repeated equipment hoisting; suitable for mobile maintenance of county-level distributed substations.

2. Transformer/Instrument Transformer Manufacturing Plants:Pre-treatment of new oil for large-capacity oil-immersed transformers; vacuum oil injection of finished products; hot oil drying of transformer body; 6000L/H high flow rate suitable for continuous operation on workshop production lines, improving factory quality inspection efficiency.

3. Third-Party Power Testing Oil Laboratory:Regeneration treatment of deteriorated oil from faulty transformers; deep purification of oil samples to produce oil products that pass insulation testing, meeting third-party certified testing oil standards.

4. International Power Transmission and Transformation EPC Projects:Suitable for 220V 60Hz power supply systems; trailer-mounted integrated unit for export; complete English operation manual; on-site oil treatment and equipment vacuum drying acceptance at substations in Europe, America, and Southeast Asia.

5. Large-scale photovoltaic/wind power substations: Outdoor, remote new energy substations undergo regular oil purification, are moved by trailer, and operate stably in the field for extended periods without fixed buildings.

6. Self-owned high-voltage power plants in metallurgy and chemical industries: Large-capacity self-owned main transformers and high-voltage reactors undergo regular insulation oil maintenance to quickly remove moisture and fault gases generated during operation, preventing partial discharge breakdown accidents.
