Why Choose Trailer Type Vacuum Transformer Oil Filter?

Writer： Kaiqian Oil Purifier Release time：2025-11-03 16:17 Clicks：

   In the fields of power generation, industrial manufacturing, and large-scale infrastructure, the purity of transformer oil directly impacts the safe operation and service life of electrical equipment. For scenarios requiring frequent relocation between job sites, addressing sudden oil treatment needs, or operating in remote outdoor locations, trailer-mounted transformer oil vacuum oil purifiers have become indispensable mobile oil treatment solutions. Their exceptional mobility, ease of operation, and perfect adaptability to large-scale, dispersed, or emergency operations make them indispensable.

The Core Advantages:

1. Ultimate Mobility and Flexibility

• Addressing Distributed Operations: Power systems have numerous substations and power distribution stations, which are widely distributed. A trailer-mounted oil purifier acts like a "mobile purification station," easily towed by construction vehicles (such as pickup trucks or trucks) to each site requiring treatment. This allows for "multi-purpose use" and serves the entire regional network.

• Fast Response to Emergency Repairs: When transformers require urgent treatment of insulating oil due to faults (such as water ingress, moisture, or degradation) or emergencies, time is of the essence. The trailer-mounted design allows for rapid deployment and immediate operation upon arrival, minimizing power outages and restoring power.

• Suitable for Off-site or Off-Power Sites: Some transformers are located in remote areas or new construction sites, where fixed power may not yet be available. A trailer-mounted oil purifier can be equipped with a diesel generator set as a power source, enabling fully self-sufficient operation, independent of site infrastructure.

2. Reduce Equipment Wear and Transportation Costs

• Eliminate Repeated Lifting and Transportation: Oil purifiers are precision equipment, containing core components such as vacuum pumps, oil pumps, and filters. If the equipment is fixed or trolley-mounted, each relocation requires a crane or forklift for loading and unloading. This not only incurs additional rental and labor costs, but the frequent jolting and lifting can also easily damage the equipment, affecting its accuracy and lifespan.

• Integrated design protects the overall structure: The trailer securely integrates all components of the oil filter (including the vacuum tank, heater, filtration system, control cabinet, and even the generator) onto a sturdy chassis. Transported as a single unit, it offers exceptional stability, reducing vibration and wear on internal piping and components.

3. Rapid deployment improves work efficiency

• Ready to use immediately: Upon arrival, the equipment requires simple preparation: lower the trailer legs for stability, connect the inlet and outlet oil pipes, and connect the power supply (or start the built-in generator). The operation is then ready to begin. This eliminates the need for complex on-site assembly and commissioning.

• High degree of integration: The trailer design provides ample space for the rational layout of all components. This typically allows for more standardized integration of oil, electrical, and control systems, providing ample access for operation and maintenance, and further improving operational efficiency.

4. Powerful Functionality and Processing Capacity
Trailer-mounted oil purifiers don't sacrifice performance for mobility. On the contrary, they are typically designed as medium-to-large, high-flow models to meet the processing needs of major projects and core equipment.

Large-Capacity Processing: They can handle the oil volume of large ultra-high voltage transformers, achieving fast and efficient dehydration, degassing, and impurity removal.

Comprehensive Functionality:

High-Efficiency Dehydration and Degassing: High vacuum and a large degassing tower deeply remove moisture and dissolved gases from the oil.

Precision Filtration: Multi-stage filter elements (with particle sizes of 1-3 microns or higher) remove mechanical impurities and free carbon.

Heating and Temperature Control: Uniform heating reduces oil viscosity, improving purification efficiency, while precisely controlling oil temperature to prevent overheating and aging.

5. Economic 
Multi-site shared equipment: For corporate groups, power companies, or professional oil filtration service companies with multiple substations, investing in a high-performance trailer-mounted oil purifier offers significantly higher utilization rates and a higher return on investment than equipping each site with a fixed unit or purchasing multiple smaller units.

Lower Overall Costs: While the purchase cost of a single trailer-mounted unit may be higher, it saves significant equipment transportation and installation costs, as well as downtime losses caused by equipment failures and repairs.

Applicable Scenarios:
Emergency maintenance ：

• Sudden transformer failures requiring on-site oil filtration, dehydration, and degassing;
• Rapid purification and regeneration of insulating oil during regular substation maintenance.

Field and remote operations：

• Maintenance of power facilities located far from cities, such as wind farms, photovoltaic power plants, and water conservancy projects;
• Oil treatment needs at substations along mines and railway lines.

Installation and commissioning of large equipment：

• Deep purification of newly commissioned transformers before oil filling.
• Recirculating oil for dehydration and degassing after transformer maintenance to ensure insulation strength.

Petrochemical and metallurgical industries:

• Multi-node oil treatment tasks within the plant, enabling efficient multi-point dispatching from one machine;

• Regeneration of industrial lubricating oil in high-temperature and highly polluted environments.
