Transformer Oil Treatment Equipment Vacuum Oil Filling Oven for power industry

Vacuum oil filling machine for transformers

1. Overview of Transformer Oil Treatment Equipment Products

The transformer oil treatment equipment is designed specifically for treating insulating oil in transformers, aiming to remove impurities, moisture, and gases from the oil, restore its insulation performance, and ensure safe operation of the equipment.

The main application is in: Oil-immersed transformers need to ensure insulation performance through vacuum oil injection technology. This process requires that the oil temperature be higher than the temperature of the transformer body (it is recommended that the temperature difference be more than 10-20℃), and the oil injection speed be controlled within 2-3T /h. Oil injection should be stopped when the oil level is 100-200mm above the top of the box, and the vacuum state should be maintained for no less than 2 hours

7. Working principle of transformer oil treatment equipment:

When the filter is working, the oil enters the primary filter through the inlet under the action of internal and external pressure difference, and large particle impurities are filtered out. After multi-stage infrared heating, the oil enters a specially designed personalized vacuum separator, where it first forms a mist and then a film, expanding its contact area in vacuum to hundreds of times its original size. The moisture in the oil is quickly vaporized under high heat, high vacuum degree, large surface, and high pumping speed conditions and discharged from the vacuum system.

The water vapor discharged from the upper part of the vacuum separator in the transformer oil treatment equipment is first cooled and dehumidified by the condenser, and then enters the cooler for further cooling. The condensed water enters the water storage tank and is discharged. After two rounds of condensation and dehumidification, the gas is finally discharged into the air by the vacuum pump.

The dry oil liquid after vacuum vaporization and dehydration in the vacuum separator is pumped from negative pressure to positive pressure by the oil outlet pump, filtered, and then discharged from the oil outlet to complete the entire oil purification process.
