How to do when the oil immersed transformer is damp? In the power system, the safe operation of the transformer is of great concern. However, the transformer is prone to many faults in operation, and the insulation is one of the main reasons for the insulation failure. It can be seen that the transformer is affected by the moisture of the transformer, especially the oil-immersed transformer. If it is not handled in time, it may directly affect the main body. So what should we do with the transformer after it gets damp? Today baoding oil - immersed transformer suppliers for the simple introduction of several methods.
The solution of the oil-immersed transformer after damp ingress:
1. Hot air drying method. The transformer is placed in the drying chamber and the hot air is used for drying. This will allow the moisture in the transformer to dissipate slowly, and the transformer will return to normal as long as the moisture is dissipated. When adopting this method, it is important to pay attention to the following two points: first, the drying chamber should be as small as possible. It is better to use the wall plate to fit the transformer body size, and the spacing between the wall plate and the transformer should not be greater than 200mm. The second is covered with asbestos board or other impregnated canvas or asbestos linen.
2. Induction heating method. Put the body in the original tank, the outer wound coil of the oil tank through the current, use the box skin eddy heat to dry. However, this method is generally not used, and the risk factor is very high. If it is not necessary, try not to use this method.
3. Zero phase sequence drying method. The transformer winding is used to heat the fuel tank, iron core and windings. Compared with other methods, this method has the advantages of simple device, small consumption, low power consumption, short drying time and high insulation quality after drying. At the same time, there are some disadvantages. It is that the transformer needs to be put in oil before and after drying, and it is necessary to change the connection mode of the winding. The heavy workload is not easy to control, and it may cause local overheating.
4. Vacuum drying method. A special kerosene vapor is used as a heat carrier, and the kerosene vapor that is imported into a vacuum tank condenses and releases a large amount of heat energy in the transformer, which is then heated by the dryer body. The thermal energy of kerosene steam can make the transformer body dry and heated more thoroughly, more uniform, efficient, and also very small to the damage degree of insulation material.
Transformer dry processing can well solve the problem of transformer be affected with damp be affected with damp, in addition to the above method, commonly used dry transformer dry processing method and eddy current method, short circuit drying method, drying oven drying method, etc., in the baoding oil-immersed transformer supplier not introduce one by one. In addition, it is important to avoid the occurrence of transformer dampness, and it is particularly important to prevent the transformer from dampening, so as to solve or avoid the problem of transformer dampness more effectively.
