Product Overview & Applications
The 2-stage Trailer Vacuum Insulating Transformer Oil Purifier Machineis a high-capacity, mobile filtration system designed to reclaim, purify, and dehydrateinsulating oil used in high-voltage electrical equipment like power transformers, circuit breakers, and switchgear. Its primary purpose is to restore contaminated oil to a condition that meets or exceeds international standards (e.g., IEC 60297), ensuring the reliability and longevity of critical electrical assets.
Applications
1. Power Transformer Commissioning and Installation:Treating new insulating oil before filling into newly installed power transformers
2.Emergency Response to Transformer Faults:On-site purification after internal transformer faults
3.Preventive Maintenance Programs::Scheduled maintenance for in-service transformer oil
4.Renewable Energy Farm Maintenance:Servicing step-up transformers in remote wind and solar farms
5.Industrial Plant Transformer Overhaul:
Maintenance of critical process transformers
6. Hydroelectric Power Plant Maintenance:Treatment of transformer oil in high-humidity environments
7.Railway Traction Power Systems:Maintenance of railway substation transformers
8.HVDC Converter Station Maintenance:Specialized purification for converter transformers
9. Disaster Recovery Operations:Restoring transformers after floods or storms
10.Oil Recycling and Reclamation::Processing used oil for reuse.
Key Features & Advantages
1. Advanced Vacuum Separation System
* Dual-stage vacuum design with 3D thin-film evaporation technology.
* Equipped with atomizer, reactor, separation chamber, foam breaker, and infrared automatic level control.
* Prevents re-dissolution of moisture and gas into oil.
2. High-Efficiency Heating System
* Indirect far-infrared radiation heating (60 kW total).
* Automatic temperature control with safety interlocks (no heating without vacuum or oil flow).
* Sectional heating control to extend component lifespan.
3. Multi-Stage Filtration System
* Three-stage filtration:
* Primary filter (80 µm, stainless steel).
* Secondary filter (20 µm, reusable stainless steel).
* Precision filter (5 µm, high flux).
* Overpressure alarm and shutdown protection.
4. Robust Vacuum System
* Rotary-vane vacuum pump (Shanghai Shengang) + Roots pump (Shanghai Cuiman).
* Cooling system for pump longevity.
* Anti-oil-backflow design and non-return valves.
5. Intelligent Control System
* Industrial-grade components (Zhengjiang Chint Electronics).
* Interlocks for vacuum pump, oil pump, and heater.
* Overload protection, thermal relays, phase sequence protection.
* User-friendly interface with indicator lights and emergency shutdown.
6. Durable Construction
* Stainless steel interfaces and bolts (304-grade).
* Anti-rust phosphate coating and spray-plastic surface.
* Trolley design with reinforced base for mobility.
7. Safety and Reliability
