La description

During storage and operation, transformer oil can come into contact with air and gases, which reduces its electric strength by ****0% (if there are no bubbles formed). Air dissolved in oil and in solid insulation reduces the electrical strength of the entire insulation structure of the transformer, which leads to the development of electrical discharges. CMM*0.6 oil purification station prevents the described above phenomena.

Many manufacturers and operators put forward strict requirements to the evacuation of power transformers and the presence of gases in transformer oils, which can extend the life and reliability of the insulation system. At the same time, the performance of transformer oil is also greatly affected by contamination with mechanical impurities and the presence of moisture. Degassing and cleaning of the insulating liquid before it is poured into the equipment allows us to guarantee good heat dissipation from the heating parts of the transformer and insulation of current-carrying elements.

Globecore Ð¡ÐœÐœ*0.6 unit is presented as mobile cart equipment, which has the next elements:

• an outlet pump;
• an electrical heater;
• fine and coarse filtrating elements;
• a cylindrical chamber with a filler;
• a vacuum pump;
• a control cabinet with a parameters display and process controlling s.

All the process can be divided into 3 main steps:

1. Pumping oil inside the vacuum pump creates a vacuum inside of the chamber, then the difference in pressure pulls dirty oil right through the first filter to remove solid particles and pumps it up into the heater.
2. Heating Inside of the electrical heater oil temperature is raised to the required for operation. Overheating is not possible because of the sensor that switch-off the heater as soon as the temperature is reached and switch-on when it drops below the installed minimum.
3. Degassing and filtration After heating oil goes into the main vessel space, loaded with a special filler that is able to extract water. The oil stream flows down to the bottom through all filler elements while vacuum also extracts moisture and gases from it. This allow us to degass and remove water at the same time, then the outlet pump draws oil through the pipe at the bottom and into the final filter, before releasing it through the outlet valve. Operator presence is not required during the process, he only needs to select a mode of operation and press the start .
