Premium slitting line manufacturer: Power quality plays a crucial role in the performance and longevity of distribution transformer substation. Poor power quality can lead to increased losses, reduced efficiency, and shorter equipment lifespan. Therefore, effective strategies for power quality management are indispensable for the optimal operation of distribution transformers. Harmonic currents, particularly those of higher frequencies, can significantly affect the performance of transformers. These currents are produced by non-linear loads such as computers, variable speed drives, and certain types of lighting systems, causing distortions in the sinusoidal waveform of the electrical supply.

Why do transformers use silicon steel sheets as iron cores? Transformers use silicon steel sheets as iron cores because silicon steel sheets have high magnetic permeability and low resistance. In a transformer, the iron core mainly undertakes the role of conducting magnetic flux. Therefore, the magnetic permeability of the iron core is very critical. Silicon steel sheet is a specially treated steel with very high magnetic permeability, can effectively conduct magnetic flux, and can reduce the loss of magnetic flux and eddy current loss. In addition, the transformer will produce electromagnetic induction phenomenon during the working process, which will generate eddy current in the iron core. These eddy currents cause loss of energy and heating of the core, reducing the efficiency of the transformer. The silicon steel sheet has low resistance characteristics, which can reduce eddy current loss and improve the efficiency of the transformer. Therefore, using silicon steel sheet as the material of the transformer core can improve the efficiency of the transformer, reduce energy loss, and reduce heat generation of the transformer, thereby prolonging the service life of the transformer.
Rising temperature: The capacity of the transformer will decrease as the temperature rises. Therefore, it is necessary to consider the appropriate heat dissipation method and heat dissipation area when designing the transformer to ensure that the temperature rise of the transformer does not exceed the allowable range. Connection method: Different transformer connection methods, such as star, delta, etc., will also affect the capacity of the transformer. For the star connection, the capacity of the transformer can be increased by about 3 times; for the delta connection, the capacity of the transformer is relatively small. Insulation level: The insulation level of the transformer determines the insulation capability and safety performance of the transformer, and also affects the capacity of the transformer. To sum up, the capacity of the transformer is related to factors such as input voltage and output voltage, load nature, temperature rise, connection method and insulation level. When selecting a transformer, it is necessary to comprehensively consider various factors according to the actual situation to ensure the normal operation and stability of the transformer.

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.
As a result of mutual inductance, a transformer produces a transformed voltage or current when the magnetic flux produced by one winding (primary winding) links with another winding (secondary winding). There is a magnetic coupling between these two windings, and they are electrically isolated. In addition, magnetic reluctance is also known as opposition to magnetic flux flow. If, for example, the magnetic flux produced by a primary winding passes through air or any nonferrous material in order to reach a secondary winding in a transformer, it would result in a reduction in magnetic flux. Due to the high reluctance of air or nonferrous materials, it will reduce magnetic flux. Read additional information on canwindg.com

The main pillar of the smart grid is the smart substation, which is not only an important hub for power transmission and distribution, but also directly affects the operational and monitoring capabilities of the smart grid through its operational safety and stability. Through the network, information can be exchanged, and the transformer can share information with the process layer and the station control layer. On the premise of ensuring product performance, the integration of monitoring, control, measurement, protection, and metering is designed to achieve the integration of transformer components with actuators, sensors, and transformers.
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.
