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?After hours of continuous trial operation with a certain load,LeobenDry type transformer setting requirements, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.Leoben,The dry-type transformer used for power plant voltage transformation is different from the oil transformer. It is strictly prohibited to lead the way at the bottom voltage side to prevent the insulation layer of the dry-type transformer from penetrating due to overvoltage caused by overvoltage at the power grid side or lightning stroke on the line.After no-load test run is normal for h, it can be transferred to on-load operation, and the load shall be gradually increased from % % and % by grade.Bella,Solenoid insulation deteriorationBefore and after sampling, clean the periphery of the sampling port with clean or hairless linen.Operation of oil immersed transformer

Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.Dry type transformer is a common electrical equipment, which can be used to convert the alternating voltage of one standard value into another standard value of the same frequency. The step-up dry-type transformer is used to convert the low-grade alternating voltage into another high-grade alternating voltage of the same frequency. It is widely used in high-frequency industries,LeobenHow much is a 250kVA box transformer, such as variable frequency power supply.When leaving the factory, so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.

The main reason is that the welding quality of electric welding is poor, there are empty welding, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.Sampling inspection,(IV) the transformer on the column shall be stable and firm, and the waist rail shall be & phi; mm galvanized wire shall be wound over turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than .m.How is the quality level of dry-type transformer compared with foreign countries?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?LeobenThe power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation, maintenance and transportation, and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.If the volume of power transformer is too small, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.For no-load impulse closing of transformer, pay attention to the following matters:
