Top dry type transformer supplier: When these harmonic currents flow through a transformer, they can cause increased core losses due to hysteresis and eddy currents. Hysteresis loss is related to the magnetization and demagnetization of the transformer’s core material in response to the alternating current. Eddy current loss occurs when induced currents circulate within the core material, creating local magnetic fields that oppose the main field. Both these losses increase with the frequency of the current. Thus, higher frequency harmonic currents can lead to considerably higher core losses, reducing the transformer’s efficiency and causing it to overheat, which can shorten its lifespan.

The cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When air cooled naturally, the transformer can run continuously for a long time under rated capacity. When forced air cooling, transformer output capacity can be increased by 50%. Suitable for intermittent overload operation, or emergency overload operation; Because the load loss and impedance voltage increase greatly during overload, it is in non-economic operation state, so it should not be in continuous overload operation for a long time.Welcome to inquiry price for dry type substation transformer.
The transformer coils are referred to as the primary and secondary windings. When applying AC current to the primary winding of the transformer, the transformer coil creates a pulsing magnetic field. The core of the transformer works to direct the path of the magnetic field between the primary and secondary coils to prevent wasted energy.The machine is a very powerful and versatile machine which can wind a wide range of HV coils for distribution transformers using round and rectangular wires. It is fully automatic with paper strip winding.Winding material lnsulated with an epoxy resin -environmentally friendly.
Adopt energy-saving measures: During the operation of the transformer, energy-saving measures can be adopted, such as adopting a high-efficiency cooling system, reducing the load rate of the transformer, optimizing the operation scheduling of the transformer, etc., to reduce energy loss and improve efficiency. Regular maintenance and overhaul: Regular maintenance and overhaul of transformers can maintain the normal operation and stability of transformers, thereby reducing energy loss and improving performance. Choose the appropriate transformer connection method: Different connection methods of the transformer will also affect the performance of the transformer. When choosing a transformer connection method, the optimal connection method can be selected according to actual needs and load characteristics to improve efficiency. To sum up, improving transformer efficiency can be achieved by optimizing design, selecting high-quality materials, adopting energy-saving measures, regular maintenance and overhaul, and selecting appropriate connection methods. In practical applications, various factors need to be considered comprehensively to select the most suitable method for improving performance.

With the development of the times, people’s demand for power supply and the reliability of power supply are increasingly high, so the smart grid has emerged accordingly.In the power system, the core and hub of the substation is the transformer.The function of the transformer is mainly to distribute and convert electric energy. The normal operation of the transformer directly affects the normal function of the substation.The intelligent operation of the transformer mainly involves the protection and status monitoring of the transformer, so as to achieve real-time monitoring of the transformer and ultimately ensure the safety and reliability of power supply.
Impedance voltage (%): Short-circuit the secondary winding of the transformer and slowly increase the voltage on the primary winding. When the short-circuit current of the secondary winding equals the rated value, the voltage applied on the primary side is the impedance voltage. It is usually expressed as a percentage of the rated voltage. Phase number and frequency: Three-phase is represented by S, and single-phase is represented by D. The frequency f of China’s national standard is 50Hz.There are countries abroad with 60Hz (such as the United States).I. Temperature rise and cooling: The difference between the temperature of the transformer winding or upper oil layer and the temperature of the surrounding environment is called the temperature rise of the winding or upper oil layer. The limit value of the temperature rise of the oil-immersed transformer winding is 65K, and the temperature rise of the oil surface is 55K.There are also various cooling methods: oil-immersed self-cooling, forced air cooling, water cooling, tube type, sheet type, etc.
Why should the iron core of the transformer be grounded? Transformer core grounding is for safety and electromagnetic compatibility considerations. On the one hand, grounding the transformer core prevents contact voltages caused by ground faults, which can pose a shock hazard to humans. Because when a ground fault occurs on one side of the transformer, the iron core on the other side may have a voltage in contact with the earth. If it is not grounded, this voltage cannot be released. On the other hand, grounding the transformer core can also reduce electromagnetic radiation interference, especially for radio equipment and communication systems. This is because the current will generate a magnetic field in the iron core. If the iron core is not grounded, this magnetic field may leak into the surrounding environment and interfere with the normal operation of other equipment. In conclusion, grounding the transformer core is a protective measure against shock hazards and electromagnetic interference.
