High Vacuum Transformer Oil Purifier Insulating Oil Dehydration Degassing Movable
High Vacuum Transformer Oil Purifier Insulating Oil Dehydration Degassing Movable
1. Functions
Sino-NSH vacuum oil filter is used to filter the insulating oil in the transformer. It removes moisture, gas, and impurities in the oil efficiently through degassing, dehydration, and precision filtration, and improves the voltage characteristics of the transformer insulating oil.
- Oil heating.
- Oil dehydration and degassing.
- Solid particle removal.
- Oil delivery.
- Air vacuum from external equipment.
2. Working Principle
When the oil filter is working, the oil enters the primary filter through the inlet under the action of the internal and external pressure difference, and the large particles of impurities are filtered out. After multi-stage electric heating, the oil enters the special personalized vacuum separator. In the vacuum separator, the surface area of the oil mist is expanded to hundreds of times the original. The water in the oil is quickly vaporized under the conditions of high heat, high vacuum, large surface, and high pumping speed and discharged by the vacuum system.
The water vapor discharged from the upper part of the vacuum separator is first cooled and dehumidified by the condenser and then cooled again in the cooler. The condensed water enters the water storage tank and is discharged. The gas after two condensation and dehumidification is finally discharged into the air by the vacuum pump.
The dry oil after vacuum vaporization and dehydration in the vacuum separator is raised from negative pressure to positive pressure by the oil pump. After fine filtration, the clean oil is discharged from the oil outlet, completing the entire oil purification process.
3. Features
- Duel-stage extreme vacuum system: can completely and efficiently remove moisture and gas.
- High-efficiency and high-power oil heating system: the heating temperature can be adjusted from 20 to 80 degrees.
- Multi-stage high-precision filtration system: completely removes trace solid particles in the oil.
- Adopt a highly secure alarm system and interlocking control: including power phase loss, phase error, overpressure, blockage alarm, etc., to ensure the automatic and safe operation of the machine.
- High automatic control: vacuum pump Roots pump oil pump heater interlocking control, and automatic start and stop.
- Simple operation, suitable for novices with no operating experience.
- With a vacuum connector: the oil filter can also be used as a vacuum pump system to vacuum equipment such as transformers.
