Oil leakage of heat pipe radiatorThe scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?Priviza,When the output power P of the transformer is equivalent to the input power P, the efficiency & ETA; Equivalent, the transformer will not cause loss. But in fact, there is no such transformer. The electromagnetic energy of transformer always causes loss. The key of this kind of loss is copper loss and iron loss. Copper loss refers to the loss caused by the number of turns of transformer coil. When the current has a fever according to the number of turns of the coil, it is called copper loss.When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?Miryang,PrivizaOverload capacity of oil immersed transformer,From the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer and only the shell can be seen for oil immersed transformer;The method and whole process of taking oil sample of power transformer are as follows:Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.

If you want to check the activated carbon fiber for the hanging cover, first take out the low-voltage waterproof sleeve and the on load transformer power switch,PrivizaDry type transformer applications, then lower the bell cover anchor bolt of the large cover, slowly hang the galvanized steel wire rope with sufficient lifting net weight on the commonly used earrings, wear round steel from top to bottom in the surrounding screw holes, and count the spacing and specifications for easy reinstallation. At the same time, the cable wind shall be added on all sides to ensure that the core international body will not be damaged during the whole lifting process. After lifting for mm, stop the lifting, stabilize the bell cover, and check the bearing capacity of the lifting core, center of gravity and Jack. After everything is normal, lift it again until the bell cover exceeds the relative height of the body,PrivizaThree phase transformer 100kW, and rotate the crane to place the bell cover on the clean skid.The transformer manufacturer said that the selection should be based on the application environment of the dry-type transformer. For the extremely extreme environment, it can operate immediately. However for the general application environment, the class H dry-type transformer can be used.If the above provisions are not met, the problem of dryness shall be solved. Generally, it is OK to operate the centrifugal fan for a period of time. Check the cleanliness of the power transformer. If too much dust is found, it must be eliminated to ensure indoor ventilation and avoid insulation penetration. In particular, pay attention to cleaning the insulators of the power transformer and the top and bottom ends of winding resistance installation. Portable centrifugal fan or dry air compression or N shall be used to clean the dust in indoor space that is not easy to reach, such as ventilation duct, and there shall be no dirt.technical service,When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.What about oil immersed transformer fire?What is the reason for the shutdown of power transformer?

The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?recommend,How much is the power transformerSeveral detection methods for installing transformerFault judgment of power transformerPrivizaIn specific daily life, oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact, computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is, the greater the output power is. On the contrary, it is very small.Power transformers are used in all walks of lifeThe tap changer of power transformer shall also have strong insulation. kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.
