The safe operation of electric power system has always been a concern of power enterprises and users. In the course of operation, the oil-immersed transformer will not only affect the service life of the equipment, but also threaten the operation safety of the transformer. So, what is the harm to the flood of the oil-immersed transformer? How to prevent it?
It is harmful to the electrical properties and physical and chemical properties of the insulating medium. The presence of moisture damage of transformer oil dielectric strength, promote organic acid corrosion of copper, iron and other metals, but also plays a role of catalytic oxidation of transformer oil, the increase of transformer oil aging faster than dry 2-4 times. Even the insulation of paper is permanently damaged. If the transformer is not processed in time, it may even cause the coil to break through to the ground, causing the equipment to be damaged.
In the operation of the oil-immersed transformer, if the transformer is found to be damp, it should be dried in a timely manner so as to avoid damage to the transformer equipment and affect the safe operation of the power system. In addition, there is also a good prevention work, avoid the oil - immersed transformer in the water - flooding problem. The preventive measures are as follows:
1. Test the oil before changing the oil or oil, so as to prevent the oil from entering the water due to improper storage during storage.
2. Before refueling the transformer, put a small amount of oil in the oil pillow. At the same time, aim the oiler at the refueling port, then slowly add it to ensure that the oil level is between 1/4 and 3/4 of the oil mark.
3. When refueling or changing oil, it should be carried out at noon on a dry sunny day, with a clean and dry container to fill the oil. It is absolutely impossible to lubricate the transformer in rainy weather.
4. Prevent transformer oil shortage. When the transformer oil level drops below the transformer shell, the contact area between oil and air increases, and the transformer oil absorbs moisture easily in the air.
5. For large-capacity transformers, use respirators and use moisture absorbent to prevent water accumulation. For small capacity transformers, it is necessary to increase the height of the tubing in the oil pillow to prevent water from entering the transformer body.
In a word, in the operation of the oil-immersed transformer, it is necessary to do a good job in the prevention work, and avoid the flooding of the oil-immersed transformer to ensure the safe operation of the power system.
