Cut to length line manufacturer by canwindg.com: 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.
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.
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 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.

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. See extra info at 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.
Poor power quality can severely impact the performance of transformer equipment, leading to a variety of negative outcomes. These consequences not only affect the operational efficiency of the equipment but also pose significant economic concerns. One of the primary damages caused by poor PQ is the deterioration of the transformer’s health. Poor PQ, characterized by factors like voltage sags, swells, harmonics, and transients, can cause excessive heating in transformers. This undue heat can degrade the insulation material used in transformers, subsequently reducing their lifespan and potentially leading to catastrophic failures. Therefore, poor power quality can lead to considerable damage to transformer equipment, resulting in economic losses, reduced energy efficiency, and decreased productivity. Therefore, maintaining high power quality is crucial for the optimal performance of transformer equipment and overall operational efficiency.
