Dry type transformer manufacturer factory 2024: 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.

A transformer coil winding machine is an intricate piece of machinery with an essential role in the manufacturing of transformers, combining modern technology and meticulousness to create high-quality products efficiently. The process starts with the feeding of copper wire into the machine, which passes through a line-up of calibrations guides and tensioners designed to secure alignment and prevent damage. An automated system then causes rotation, gradually looping copper wire around the transformer coil. A computerized system oversees variables such as speed, pitch control, layer count and insulation thickness for consistent turns. Moreover, for distinct transformer models or designs, these machines can be fitted with extra features such as automatic lead cutting and tapping mechanisms for increased versatility and productivity.
Current source inverter has a higher power factor: The current source inverter has a higher power factor, which can achieve higher power factor correction, thereby reducing grid harmonic pollution. However, since a higher power factor requires larger capacitor support, a transformer with a larger capacity needs to be selected to meet the power supply requirements of the capacitor. Current source inverter needs additional power supply: The circuit of current source inverter needs additional power supply to ensure the normal operation of the current loop control. These additional power sources need sufficient capacity to support, so a transformer with a larger capacity needs to be selected to meet the power supply requirements. Therefore, the current source inverter needs a larger transformer capacity to ensure the normal operation of the intermediate inductor, support the power supply of the capacitor and meet the power supply requirements. When selecting a transformer, it needs to be selected according to the actual electrical parameters and performance requirements to ensure the normal operation and stability of the inverter.

The loss in magnetic flux in the transformer must therefore be minimized by providing a suitable mean between the primary and secondary windings. For this purpose, silicon steel magnetic cores are usually used. By using a core type transformer, magnetic losses are reduced and a greater amount of magnetic flux is conveyed between the primary and secondary coils, thereby increasing the transformer’s overall efficiency. Electrical materials play an important role in the field of engineering technology. Various technologies should be realized through certain equipment, and the equipment needs to be made of specific materials. Without corresponding materials, even technologies and products that are feasible in principle cannot be realized. The emergence of new materials can often bring significant technological progress.

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.
What are the consequences of parallel operation of transformers that do not meet the parallel operation conditions? Parallel operation of transformers that do not meet the parallel operation conditions may lead to the following consequences: Voltage instability: Different transformers may have different electrical parameters, such as transformation ratio, resistance, inductance, etc. If these transformers with different parameters are forced to run in parallel, the overall electrical parameters after paralleling may be unstable, thereby affecting the quality of power supply. Uneven load distribution: If the transformers with uneven load distribution are forced to run in parallel, different transformers may bear different loads, thus affecting the service life and stability of the transformers. Excessive temperature rise: If different transformers are operated in parallel, their heat dissipation conditions and methods may be different, which may cause excessive temperature rise of some transformers, and may even damage the transformer.
