Insulating or Transformer Oil Handling Plant
for handling and maintenance of large quantity of transformer oil
Insulating/Transformer Oil Handling System is the complete solution to handle the insulating/transformer oil, the system is able to keep the new and old oil in excellent condition. The Insulating/transformer oil handling system consists of the following equipment:
- Skid or Trolley mounted Insulating/Transformer oil filtration plant with inbuilt transformer evacuation system,
- Regenerative air dryer,
- Insulating oil transfer pump,
- Insulating oil storage tank,
- Separate Evacuation System for Transformer tanks
Regenerative Air dryers
The air dryer is regenerative type to fill the dry air in transformers when required.
Transformer Evacuation System
Transformer evacuation system consisting of vacuum pumps, roots pump, etc. is provided for purpose of evacuating transformer tank and have sufficient capacity and evacuation level, when connected to main transformer tank. Vacuum gauges is also provided to monitor vacuum at various stages in the transformer evacuation system.
Oil Storage Tank
The oil tank is horizontally mounted on wheels equipped with inspection manholes & gauge glasses. The tank can also be provided with suitable saddles so that it can be rested on ground after removing from the trolley. All tank vents are fitted with dehydrators to prevent the entry of moisture into the tanks. The oil tanks shall be vacuum tested and for leakage as well.
Oil Transfer Pump
The oil transfer pump is of vacuum tight positive displacement gear type with horizontal driving shaft directly connected to its electric motor through a flexible coupling. The oil transfer pump can be wheel (castor wheel or pneumatic wheel) mounted or skid mounted. The transfer pump is equipped with pressure relief valve to protect the pump against excessive pressure in case of throttling in the discharge line.
