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.

A transformer core is a static device that provides a channel for magnetic flux to flow in a transformer. The core is constructed using thin strips of silicone steel. The silicon steel sheets are electrically isolated and coupled to reduce no-load losses in the transformer.The core of a transformer is made of soft iron. Transformers are used in various fields like power generation grid, distribution sector, transmission, and electric energy consumption.
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.
The metal laser cutting machine focuses the laser emitted from the laser into a laser beam with high power density through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or gasified metal. With the movement of the relative position between the beam and the workpiece, the material will finally form a slit, so as to achieve the purpose of cutting. Laser cutting process uses invisible light beam to replace the traditional mechanical knife. It has the characteristics of high precision, fast cutting, not limited to the limitation of cutting pattern, automatic typesetting, material saving, smooth incision and low processing cost. It will gradually improve or replace the traditional metal cutting process equipment.Want to konw more about metal cutting machine, contact us, one of the most professional metal laser cutting machine manufacturers & suppliers in China.

The cut to length line is a special equipment for the production of transformer core, is our latest generation of cross shear line. This cut to length production line is used for shearing, O punching and V notch of transformer core sheet. The special point of this ctl line is that two O punch and one V notch can work at the same time to produce transformer core pieces with 3, 5, 7 steps in vertical direction and 3, 5, 7 steps in horizontal direction.
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. Discover even more info on https://www.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.
What does the rated value on the nameplate of the transformer mean? The rated value on the transformer nameplate refers to some important electrical parameters and performance indicators of the transformer. Usually includes the following aspects: Rated capacity: The rated capacity of a transformer refers to the maximum load electric power that the transformer can continuously supply. For example, a 10MVA transformer means that the transformer’s maximum load can reach 10 megawatts. Rated voltage: The rated voltage of the transformer refers to the design voltage of the transformer. For example, a 220kV/110kV transformer means that the input voltage of the transformer is 220 kV and the output voltage is 110 kV. Rated frequency: The rated frequency of a transformer refers to the power frequency for which the transformer is designed. In China, the power frequency is usually 50Hz. Short-time withstand current: The short-time withstand current of a transformer refers to the maximum current value that the transformer can withstand in a short period of time. For example, the short-term withstand current of a transformer is 50kA, which means that the transformer can withstand an instantaneous current of up to 50 kA.
