The safe operation of power system has always been a concern of power enterprises and users. In the course of operation, the oil-immersed transformer can not only affect the service life of the equipment, but also threaten the operation safety of the transformer. So, what is the harm in the flood water of baoding oil immersed transformer? How to prevent it?

It is harmful to the electric and physical 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 handled in a timely manner, it can even cause the coil to hit the ground or the coil is short-circuited, causing the equipment to be damaged.

In the operation of the oil-immersed transformer, if the transformer is found to be wet, the transformer should be dried in a timely manner so as to avoid damaging the transformer equipment and affecting the safe operation of the power system. In addition, it is also good to prevent the flooding of oil-immersed transformer. The preventive measures are as follows:

1. Before replacing oil or refueling transformer, test the oil products to prevent oil products from entering the water during storage.

2. Before refueling the transformer, a small amount of oil should be put out of the oil pillow. At the same time, the oiler should be pointed at the refueling port, then slowly add it to ensure the oil level is between 1/4 and 3/4 of the oil mark.

3. During the oil filling or oil change, it should be carried out at noon on a dry sunny day and filled with oil in a clean and dry container. It is absolutely impossible to refueling the transformer in rainy weather.

4. Prevent oil shortage from transformer. When the transformer oil level drops below the transformer shell, the contact area of oil and air increases, and the transformer oil can absorb moisture easily in the air.

Use respirators for large capacity transformers and use hygroscopic agents to prevent water accumulation. For small capacity transformers, it is necessary to improve the height of the tubing in the oil pillow to prevent water from entering the transformer body.

In conclusion, in the operation of the oil-immersed transformer, it is necessary to do a good job in preventing the water flooding of the oil-immersed transformer in order to ensure the safe operation of the power system.
