Transformer core cutting line manufacturer from China: 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.

What is eddy current? What are the disadvantages of eddy current generation? Eddy current refers to a kind of current generated in the conductor, which is the induced current caused by the change of the magnetic field. The eddy current forms a circular current flow path in the conductor, and this current forms a motion state similar to an eddy current inside the conductor, so it is called an eddy current. The generation of eddy currents has the following disadvantages: Energy loss: Eddy currents create circular currents in conductors, which generate heat as they flow continuously in conductors. Since the generation of eddy currents is caused by changes in the magnetic field, in equipment such as transformers and motors.
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.

Oil immersed transformers are the most commonly used equipment mainly because of their simple structure and reliable operation. It has faster heat dissipation, uniform conduction, and better insulation performance than the dry-type transformer.Oil transformers are used in power distribution or electrical substations. Their transformer core and coils are immersed in oil, which cools and insulates. Oil circulates through ducts in the coil and around the coil and core assembly, moved by convection.
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.
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.

Connection group label: According to the phase relationship between the primary and secondary windings of the transformer, the transformer windings are connected into various combinations, which are called the connection group of the windings. In order to distinguish different connection groups, the clock notation is often used, that is, the phasor of the line voltage on the high-voltage side is used as the long hand of the clock, fixed at 12, and the phasor of the line voltage on the low-voltage side is used as the short hand of the clock. The number of the short hand indicates the connection group label. For example, Dyn11 indicates that the primary winding is (triangle) connected, and the secondary winding is (star) connected with a center point, and the group number is (11) points.
