Easy Control Portable Movable Transformer Oil Processing Equipment
1. This transformer oil processing equipment adopts an interlock protection system to connect the oil pump, heater and liquid level sensor to avoid blank heating, blank pumping, oil leakage and electricity leakage. If there is any fault, the machine can automatically cut off the power.
2. It can be used in conjunction with an insulating oil regeneration device to decolorize (remove acids, oxides, free carbon), reduce dielectric loss, and make the processed oil clearer.
3. Transformer oil filtration equipment can not only handle waste transformer oil. This machine can also process acid, sludge, carbon and decolorize and get food quality transformer oil.
Usages of Transformer Oil Processing Plant:
-
Tongrui ZJAseries double-stage vacuum transformer oil processing equipment is widely used for industries of the power plant, power station, electricity company, transformer factory, metallurgy, petrochemical, mechanical engineering, transportation, railway and transformers manufacturing, etc.
-
Especially, it applies to the maintenance of transformers above 110KV and deep purification of high-grade new transformer oil, imported transformer oil, mutual inductor oil and ultra-high voltage transformer oil.
-
It can be also used for oil vacuum filling and vacuum drying as well as transformer vacuum evacuation operation. Moreover, the machine can be working online without the stop of transformers.

Advantages of Transformer Oil Processing Plant:
1.Advanced double-stage large capacity dehydration and degassing system which adopts large-area three-dimensional flash evaporation technique.
2. Widely used for transformers on-site installation or maintenance to fill oil into transformers and circuit breakers under vacuum condition or conduct transformers evacuation operation.
3.The precise filtration system, high-quality filtering elements and multi-stage filtration with gradual precision.
4. Equipped with automatic temperature control system, liquid-level control system, defoaming control system, pressure protection system and high-quality main components.

5. The machine supports on-line operations without supervision with indicators to show operation status.
6. The transformer oil processing equipment adopts a humanization design with low noise, easy operation, long free-maintenance time and energy saving to lower the operation cost.
7.With electrical control inter-lock design. The vacuum system, oil pump system and heating system are interlocked in control.
8. Equipped with an indication for changing filters and automatic stop devices for overloaded filters.
9. Equipped with an emergency stop for electric leakage and power overload to protect the motor.
10. With phase-sequence, the phase loses protection function and safety control for sudden shut-down.
11. Equipped with vacuuming interface for the transformer evacuation operation.
12. The outlet and inlet can be interchanged.
