Transformer core cutting line manufacturer today
Excellent dry type transformer 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.

The efficiency of the transformer refers to the energy conversion efficiency of the transformer, that is, the ratio of the output power to the input power. Improving the performance of transformers can reduce energy loss and energy consumption, thereby improving the economy and reliability of transformers. Here are a few ways to improve transformer performance: Optimizing transformer design: When designing a transformer, optimized design methods can be used, such as reducing the reluctance of the iron core and winding, reducing copper loss and iron loss, etc., thereby reducing the energy loss of the transformer and improving performance. Choose high-quality materials: When manufacturing transformers, you can choose high-quality materials, such as low-loss silicon steel sheets, high-conductivity materials, etc., to reduce material loss and energy consumption and improve performance.
Laser welding machine is an efficient and precise welding method using high energy density laser beam as a heat source. Laser welding is one of the important applications of laser material processing technology. It mainly used for welding thin wall material and low speed in the 1970 s. The welding process is thermal conduction, i.e. the laser radiation heating surface, the surface heat to the internal diffusion through heat conduction, by controlling the width of laser pulse, energy, peak power and repeating frequency, parameters such as melting of components, to form specific molten pool. Because of its unique advantages, it has been successfully used in precision welding of micro and small parts.As one of the best laser welding machine manufacturers in China, Canwin specialized in handheld laser welding machine and wholesale fiber laser welding machine making for over 20 years.

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.

Digital measurement – Digital measurement of transformers or other components can be conducted, and the measurement results can be called and collected from the process layer and station control layer through digital networks, thus monitoring transformers and other equipment.Status visualization – The operation status of transformers can be visualized and observed in the power grid.Smart grid or other related systems can express the status information of transformer self-detection or information interaction.
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.
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.
